How to freeze buttermilk

A refrigerated carton of unopened buttermilk should be safe to drink up to two weeks after its best-by date. An opened container stored in the fridge, meanwhile, will be good for 14 days after it's opened. 

How Can You Tell If Buttermilk Has Gone Bad?

When buttermilk is past its prime, its consistency will change: It will become thick and chunky instead of smooth. Fresh buttermilk has a relatively tangy odor, but expired buttermilk will smell strong and sour. Of course, if your buttermilk is growing mold or is discolored, throw it out. 

Can You Freeze Buttermilk?

Yes! You can freeze buttermilk, and you absolutely should if you don't think you'll use it up before it expires. It should stay good in the freezer for about three months — about two and a half months longer than refrigerated buttermilk. 

How to Freeze Buttermilk

You can freeze buttermilk in its original carton, but only if you've already used some of it. Liquid expands as it freezes, so it needs a little bit of room to grow. You can also freeze buttermilk in an ice cube tray (this is especially handy if you'll only use a little bit at a time). 

Our favorite way to freeze buttermilk, though, is in precise measurements in freezer-safe bags. Why? You'll only have to thaw exactly how much you need for a given recipe. Make life a little easier on your future self by dividing the liquid up into common portions (1 cup, ½ cup, ¼ cup, etc.) and labeling the containers with the date and amount. 

To freeze buttermilk:

  1. Decide how you want to divide the buttermilk. One quart-sized carton contains about 4 cups. You could freeze four cups separately or you can mix and match the measurements: Cover all your bases by freezing two 1-cup portions, two ½-cup portions, and four ¼-cup portions. 
  2. Label freezer-safe bags with the date and measurements. You’ll want to get your labeling out of the way before divvying up the buttermilk, as it’s no fun trying to write on liquid-filled bags. If you want to go the extra mile, you can pull out your calendar and calculate the date three months from now — this’ll serve as your easily accessible expiration date. 
  3. Pour the buttermilk (in pre-measured portions) into the bags. Remove as much excess air as you can before sealing the top. Lay the bags flat in the freezer to save space. 

How to Thaw Buttermilk

To thaw frozen buttermilk, simply transfer it from the freezer to the fridge the night before you plan to use it. If you're short on time, fill a bowl with warm (not hot or boiling) water and submerge the sealed bag. The buttermilk should thaw in about half an hour, though you may need to replace the water once or twice as it cools.

If you’re like me, you lament the fact that buttermilk is only available in quart-sized containers. I mean, really, you can buy a pint or half-pint of cream, heck, you can even buy pint of milk these days, but only full quarts of buttermilk?

If you’re also like me, buttermilk isn’t exactly the most commonly used item in your kitchen. You need it every now and then when you are making some biscuits or pancakes or chess pie, but those use maybe a cup or two at most. Sure, since buttermilk is already slightly soured it does last longer than regular milks, but it won’t last forever. And if you’re (once again) like me in that you feel the good, full-fat stuff is well worth the extra money, you don’t exactly like the idea of wasting it.

How to freeze buttermilk

Luckily, freezing buttermilk is incredibly easy, and if you measure it out according to what you most use it for, (3/4 cup for one batch of biscuits in my case) you can thaw it out as needed.

First, make room in the freezer. You’ll want space for a cookie sheet to lie flat and level in your freezer. I find arranging a bunch of boxes of waffles and bags of frozen fruit to form a sort of level platform. But maybe your freezer is more orderly than ours (it wouldn’t take much) and you’ve got plenty of space. If so, lucky you. You should really freeze more stuff.

How to freeze buttermilk

Label your bags. I recommend including the description and amount of what’s inside, as well as the date. Because no matter how good you think your memory is now, you will not remember what that random bag of stuff is in 4 months. I promise you. Labeling is your friend.

How to freeze buttermilk

Portion out your leftover buttermilk into the labeled bags. Fold them over to press out any remaining air inside, then seal and lay them flat on a cookie sheet.

How to freeze buttermilk

Why flat? Well, they’ll freeze that way. And then you can stack them up nice and neat in your freezer, alongside your egg whites and tomato sauce and basil pesto (which you can also freeze the same manner). Like your own little frozen foods library.

How to freeze buttermilk

To thaw your buttermilk, just put the bag in the fridge overnight until it’s thawed. Or, if you’re like me (and really, most of you probably are in this sense) you forget to thaw it ahead of time and need to use it immediately. Fill a baking pan with lukewarm water and submerge the bag. Swap out the cold water for new lukewarm water once or twice as needed, and in about 20 minutes your buttermilk should be totally thawed. That’s another benefit to flat-freezing: much quicker thawing times than if you were to freeze them in a blocky container.

Do you have leftover buttermilk and don’t want it to go to waste? You can freeze buttermilk to save for use at a later date! Let me show you how.

Can you freeze buttermilk?

A reader recently asked for recipes using buttermilk because she always has some leftover. Blueberry buttermilk scones, parmesan buttermilk drop biscuits, and cheddar jalapeno buttermilk bread are all great options for using that leftover buttermilk but I also want to let you in on a little secret…

You can freeze leftover buttermilk and never worry about wasting it again. It’s actually quite simple to freeze and it will last several months in the freezer.

How long will frozen buttermilk last?

You can freeze buttermilk for up to 3 months. After three months, the buttermilk will begin to clump and congeal.

How to freeze buttermilk?

Step 1: Portion the buttermilk for freezing.

I like to portion the buttermilk into ¼ and ½ cups. Use zip-top freezer bags and write the portion size and date on the bag.

You can also use a silicone muffin pan to portion ¼ cup sizes.

Step 2: Freeze for up to 3 months.

Lay the bags of buttermilk flat on a baking sheet and freeze for 3 hours. You can then rearrange the bags to fit better in your freezer. I like to place all the same size portions in a larger zip-top bag.

If you are using a silicone muffin pan, you can pop the portions out of the pan once they are frozen solid and store them in a large zip-top bag.

The great thing about laying the bags flat to freeze is the thin layer of frozen buttermilk will thaw quickly. Just set it out on the countertop for 15-20 minutes.

If you are in a huge hurry, you can set the bag of frozen buttermilk in a bowl of warm water for about 5 minutes.

The consistency of the buttermilk will be different after it thaws. It may even appear separated. Give it a good whisk and it’ll be ready for use in your baked goods.

When you don’t have buttermilk on hand at all, you can actually make a quick substitute. See my thorough post on how to make buttermilk at home.

How to freeze buttermilk

Can’t use that quart of buttermilk soon enough? No problem! You can freeze buttermilk so that you can use it later in your favorite recipes.

Buttermilk is a versatile cooking and baking ingredient that brings tangy creaminess to Buttermilk Ranch Dressing and marinades and makes Buttermilk Cornbread light and fluffy. It’s an essential ingredient in a number of recipes, so keep some on hand!

What gives Fried Chicken Sandwiches their characteristic tenderness under the breaded coating? What makes Buttermilk Biscuits fluffy? What makes Creamy Garlic Dressing with Cilantro so creamy?

Buttermilk, that’s what.

Buttermilk, the highly underrated dairy product is a powerhouse in the kitchen. On family farms it’s the liquid left after churning butter, but commercially it’s a cultured milk that’s slightly thick and tangy. It does wonders for marinades, dressings, baked goods, and any number of recipes that call for buttermilk.

The only problem is that it’s not cheap and unless you’re in the habit of using it, it can be difficult to use up the full quart. You can culture your own buttermilk, of course, to reduce costs a bit, but you still need to use it up.

Can you freeze buttermilk?

Yep, you sure can!

Why Do This

It helps you avoid food waste and save time and money. If you’ll use it eventually but can’t just right now, why not freeze it to use later and buy yourself some time and money?

Freezing buttermilk and other ingredients you can’t use before they spoil is a great way to extend their shelf life, stock your kitchen, and make the most of your grocery dollar.


How to freeze buttermilk

All you need is buttermilk! This can be cultured buttermilk that you make yourself or the commercial style that you picked up in the dairy section of the grocery store.

Make sure that it smells good. Usually it smells fresh and creamy, though it might have a slight sour smell. It won’t smell bad. If it does, discard it; freezing won’t help.

So long as your buttermilk is fresh, you should have no problems freezing it to use later.

Step-by-Step Instructions

You’re most likely to use buttermilk in 1- or 2-cup portions so freeze it already measured and ready to go. You can use small freezer-safe containers with lids or freeze it in 1- or 2-cup Souper Cubes (like large ice cube trays).

If you use individual containers, be sure to label them before you fill them and leave 1/2-inch headspace to allow for expansion.

If you use Souper Cubes, transfer the frozen bricks to a labeled, ziptop freezer bag in the freezer.

Thawing Instructions

To thaw buttermilk to use in recipes, transfer the container to the refrigerator to thaw overnight. If you used Souper Cubes, you can transfer a 1-cup brick into a wide-mouth mason jar and place that in the fridge.

Allow the buttermilk to thaw completely before whisking it to recombine any milk fat that may have separated. Then use it in your recipes.

If you don’t have any buttermilk, you can make a “sour milk” to use in baking recipes by combining 1 tablespoon of white vinegar with regular milk to equal 1 cup. Allow this to set for a few minutes before using in your recipe. It tends not to work well in marinades and dressings.

Alternatively, you can combine equal parts of milk with sour cream or plain yogurt. This works in all kinds of recipes.

Buttermilk is a thick, cultured milk that is excellent in dressings and marinades. It also adds lift to baked goods, thanks to the acidity present. It’s often used in scones, biscuits, pancakes, waffles, and fried chicken recipes.

Buttermilk is often an essential ingredient in baking recipes. But unless you use buttermilk regularly, you could end up with a partial container left over from a recipe. It won’t last long in the fridge. So the question is, can you freeze buttermilk so you can use it in future recipes? The answer is yes, buttermilk can be frozen. The USDA says the shelf life of buttermilk in the refrigerator is about two weeks, and once it is frozen it will last for three months. After three months, you should find a way to use it or you should discard it.

How to Freeze Buttermilk

Before you freeze leftover buttermilk, check it to be sure it hasn’t gone bad. Even if it isn’t past its “best by” date, it could have been mishandled or contaminated and that would speed up the rate of spoilage. If it is so chunky you can’t pour it, has visible mold, or a strong sour odor, toss it out rather than freeze it.

You can freeze buttermilk in its original container, but be sure there is enough space left in the carton to allow it to expand when it freezes. If you’re freezing the milk in the container, keep in mind that you’ll have to use it all when you defrost it.

It’s more convenient to freeze buttermilk pre-measured in the amounts you will use in future recipes. If you generally use a small amount, freeze the buttermilk in ice cube trays and store the cubes in a freezer bag once they are frozen hard.

Silicone baking forms for muffins or mini-muffins are handy to use for freezing a cup or half cup of buttermilk. Measure and pour it into the form and allow it to freeze. Then pop out the frozen buttermilk cakes and store them in a freezer bag.

Always label the frozen buttermilk and the date you froze it. Otherwise, it's easy to lose track of when you froze it and keep it longer than it is good to use. You might also confuse it with other items in your freezer.

Using Frozen Buttermilk

Frozen buttermilk is best used in cooked or baked dishes. It won’t maintain its qualities for drinking or using in uncooked recipes after you have frozen it. Frozen buttermilk maintains its acid content, which is used in baking and is the quality that tenderizes meat when used as a marinade.

Thaw the frozen buttermilk in the refrigerator before you use it. If you’re looking for ways to use buttermilk, look no further than traditional Southern cooking, where it’s found in two tasty examples: cornbread and breading for fried chicken.

Is It Safe to Use Thawed Buttermilk After a Power Outage?

If you have a power outage while your buttermilk is in the freezer, the USDA recommends discarding it and other milk products if they have been held at a temperature above 40 F for more than 2 hours. Butter would be safe to use.

We've all been there: You bought a quart of buttermilk to make our best-ever biscuits, and suddenly a week has gone by and you still have half of a carton left in the refrigerator. While there are tons of delicious and creative ways to use buttermilk (Herbed Buttermilk Ranch Dressing or Triple-Chocolate Buttermilk Pound Cake, anyone?), you can store it in your freezer with great results.

Simply give the buttermilk a good shake and pour it into ice cube trays by the tablespoon. Once they are frozen, pop the cubes into a ziplock plastic freezer bag. Like all frozen foods, buttermilk will keep indefinitely if properly frozen, but it will taste best if used within three months.

Watch: Triple Chocolate Buttermilk Pound Cake

When a recipe calls for buttermilk, defrost as many cubes as you need in a small bowl or jar in the refrigerator, or heated for ten seconds at a time on ‘LOW' in the microwave. Once frozen, the buttermilk solids and whey will separate, so before you use the defrosted buttermilk, be sure to vigorously stir or shake it until the liquid comes together.

Before you break out the ice cube trays, buttermilk can be kept in the refrigerator longer than you might think. After you open the carton, it can be refrigerated up to three weeks if you keep the carton tightly closed. If you're unsure of whether it has gone ‘off' or not, give it a whiff and make sure the texture is smooth, not lumpy.

As refrigerated buttermilk ages, it loses its signature tanginess, so while it has a long shelf life, for the most flavor, you should use it up sooner rather than later—or freeze it.

Buttermilk is hard to come by in the smaller quantities usually required in baking and cooking recipes. This means that you will generally be left with half a container of buttermilk that won’t last long even when refrigerated. So, how can you avoid wasting the leftover buttermilk?

Dairy products don’t usually have a good reputation when it comes to freezing, however, since buttermilk is mostly used for cooking and in baking recipes, it can successfully be stored in the freezer to prolong its shelf life.

Now you can measure out the quantities required in your recipes, freeze them and simply pull out the amount you need without wasting a single drop.

Here is everything you need to know about freezing buttermilk.

Types of Buttermilk

Buttermilk first originated as a by-product after churning butter out of cultured cream. Modern-day buttermilk, however, is a fermented, or cultured milk product.

Although some populations enjoy buttermilk as a drink, it is often used in baking and marinating meat due to its acidic quality.

The acid in buttermilk reacts with raising agents in baked products such as sour-dough bread and scones to create an airy, well-risen dough. The acid also helps to tenderize meat, retain moisture, and enhance added flavorings when cooking meat.

Buttermilk may seem like just a sour milk product, but it adds great quality and enhances both sweet and savory cooked, baked, battered- and fried dishes.

Can Buttermilk Be Frozen?

Buttermilk is suitable for freezing only if you are planning to use it for baking or adding to a cooked dish after freezing.

The consistency of buttermilk changes on freezing appearing separated once thawed. By whisking the thawed buttermilk, you can reconstitute its smoother consistency.

It is important to keep buttermilk in air-tight packaging in the freezer to prevent it from absorbing odors from surrounding items. The last thing you want is buttermilk with a slightly fishy or oniony flavor.

Buttermilk needs to be frozen while it is still fresh. Placing it in the freezer will not revive old buttermilk, so keep in mind that if it is already off, it is best to throw it away. Buttermilk that has been in the refrigerator for more than 2 weeks should not be frozen.

How To Freeze Buttermilk

Step 1: Quality Check

Check that the buttermilk you are going to freeze has not gone bad. If it has a strong sour odor, has mold, or is too chunky to pour, it needs to be discarded.

Step 2: Portion and Pack

It is best to portion the buttermilk into the quantity you will be needing once thawed. You can either do this by freezing it in an ice cubes tray or by measuring out ½ to one cup portions into freezer bags.

Ice cubes

To freeze the buttermilk in small portions, pour it into an ice-cube tray and place it in the freezer until fully frozen. Remove the frozen buttermilk cubes from the tray and transfer them into a resealable freezer bag.

Before sealing the freezer bag, press out all the air to avoid freezer burn and the absorption of surrounding odors.

Freezer Bags

Alternatively, measure out the desired quantity and pour the buttermilk into a resealable freezer bag. Press out the air, seal the bags, and lie them flat on a baking tray.

Place the level baking tray in the freezer to allow the buttermilk sachets to freeze evenly making for easy storage, no spillage, and even thawing.

Once frozen, you can remove the baking tray and conveniently stack the bags.

Step 3: Label

Label the freezer bags with the content and date of freezing. No matter how good your memory is, chances are you will either forget what the product is or for how long it has been in the freezer as the weeks tick by.

Place the labeled bag of cubes, or flat-frozen freezer bags into the freezer until needed.

How To Thaw Frozen Buttermilk

Method 1: Refrigerator

Remove the portion of buttermilk you would like to defrost from the freezer and place it directly into the fridge to thaw for a few hours.

On thawing, the buttermilk would have split and become watery. Mix it well with a whisk to reconstitute a smooth consistency.

Method 2: Water Bath

If you do not have time to wait for the buttermilk to defrost in the refrigerator, you can also place the sealed zip lock bag in a bowl of water for 20 to 30 minutes to defrost.

How long does buttermilk last?

Buttermilk will last for 2 weeks in the refrigerator once opened. When kept in an air-tight container or sealed freezer bag, buttermilk will last safely for 3 months in the freezer.

How do you know if buttermilk is off?

Once buttermilk becomes thick, lumpy, and is no longer smooth to pour, it is likely spoiled. Buttermilk that has gone off will also develop a sour odor and slight change in color.

Can you freeze unopened buttermilk in its store-bought container?

You can freeze buttermilk in its original container, unopened, by placing it directly in the freezer. You do, however, want to ensure that there is enough headroom for the buttermilk to expand in the freezer so that the container does not burst. You can place the container in a sealed zip lock freezer bag as an extra precaution.

Keep in mind that you will have to defrost the entire carton when needed, so it may be more convenient to decant it into smaller quantities for future use.

Can you refreeze buttermilk?

No, buttermilk should only be frozen once. Freezing and thawing buttermilk more than once will break down the texture further and cause harmful bacteria to breed.


Since freezing buttermilk does not affect its taste or acidic quality, it is the perfect way to preserve this dairy ingredient to save money and prevent food wastage.

It won’t be suitable to drink as is after freezing, however, you can use it for any baking, cooking, and marinating meat. Buttermilk is also a popular ingredient in making batters for deep-fried items. If you run out of this ingredient, you can always find a buttermilk substitute for your recipe.

Just remember, if you want the best out of your frozen buttermilk long-term, it needs to be kept in an air-tight freezer bag or container. Once thawed, give it a good whisk to reconstitute its creamy consistency, and get baking!

How to Freeze Buttermilk

If you buy buttermilk for a recipe, and the rest of the quart always go bad before you find a way to use it, then, do what I do, and freeze the extras. Here’s the method that I’ve been using for years.

The Best Way to Freeze Buttermilk

While it’s perfectly fine to freeze buttermilk in its original container (with a cup or two of milk removed to allow for expansion), this leaves you having to thaw the entire jug every time you need buttermilk for a recipe, – which could take days – and will once again leave you with a large amount of buttermilk to either use up or refreeze.

Since most recipes call for a cup of buttermilk, or less, it’s far more convenient to freeze your buttermilk in small, pre-measured amounts. This allows you to grab just what you need, while drastically reducing thaw time.

How to freeze buttermilk

Muffin pans and ice cube trays make this easy to do. Just measure how much liquid fits into a single ice cube compartment or muffin cup. Ice cube trays typically hold two Tablespoons, and muffin pans typically hold between 1/4-1/2 cup, but it’s good to know precisely what yours holds. Be sure to write the measurements down somewhere, so you’ll have them for future reference.

How to freeze buttermilk

Then, fill the compartments with buttermilk, and pop the trays or pans in the freezer.

How to freeze buttermilk

I stick my muffin pans or ice cube trays on a baking sheet. Then, carve out a level spot for it in the freezer, before I start pouring. This allows me to go straight from the counter to the freezer without any spills.

How to freeze buttermilk

Once the buttermilk is fully frozen, pop the cubes out of the trays or pans, and transfer them to freezer bags. Label the bags with the contents and portion sizes, to avoid recipe mix ups.

How to freeze buttermilk

If your ice cube tray holds two Tablespoons, like mine, here are the cube-to-cup conversions:

  • 2 cubes = 1/4 cup
  • 4 cubes = 1/2 cup
  • 6 cubes = 3/4 cup
  • 8 cubes =1 cup

How to Use Frozen Buttermilk

To use your frozen buttermilk, simply grab the number of cubes you need, and allow them to thaw in the fridge overnight. If you’re using them in a hot dish, like mashed potatoes or soup, just drop the frozen cubes straight into the dish; they’ll thaw as the dish cooks.

In a hurry? Then, heat the buttermilk in a small pan, or microwave it for 10 seconds at a time, until it thaws.

Freezing buttermilk causes the whey to separate from the solids. There’s no need to do anything about it, if you’re using it for cooking or baking. But, if you’re using your buttermilk to make salad dressing, or another uncooked dish, you’ll want to reincorporate them. This just requires a quick whirl in the blender.

Does Freezing Buttermilk Kill the Active Cultures?

Nope, the cultures become inactive when they’re frozen, but as soon as the buttermilk thaws they become active again. So, if you want to use your frozen buttermilk to make sour cream, cheese or another recipe that relies on the active cultures in the buttermilk, you can still do that. Just allow the buttermilk to thaw in the fridge (not the microwave), and you’re good to go.

The Shelf Life of Frozen Buttermilk

Frozen buttermilk is best used within three months, but it’ll keep indefinitely. Just squeeze the air out of your freezer bags, before you seal them, so your buttermilk doesn’t develop freezer burn, and it’ll keep, until you need it.

Uses for Buttermilk

Switch to Powdered Buttermilk

If you never seem to have buttermilk when you need it, or you’re tired of having to buy a quart, when you only need a cup, consider switching to powdered buttermilk. Just reconstitute it with water to make as much, or as little, as you need, and there won’t be any waste. Easy!

Can you freeze buttermilk is a question often asked by bakers everywhere – for good reason too! Buttermilk only seems to come in large portions and it is rare for any baking recipe to require the whole carton. So does it freeze ok?

Buttermilk can be frozen for up to 3 months. You can either freeze it in good-quality freezer bags or you can use a muffin tray depending on the quantity you would normally use in your cooking and baking.

Can You Refreeze Buttermilk? No

How To Freeze Buttermilk

There are a couple of methods of freezing buttermilk and both work absolutely fine. The method you choose is down to your personal preferences and the amount you want to have in each portion.

The first method we have outlined below is perfect in large quantities. If you know you’ll only need a little at a time, then the second method using a muffin tray is perfect.

How to Freeze Buttermilk In Freezer Bags

The first method is perfect for larger portion sizes of buttermilk – great for those times when you have lots of baking to do.

  1. Label Bags
    Label some freezer bags so you know exactly what is in the bag. You will want to add the date too so you know when you need to use it by.
  2. Portion Out
    Measure out a portion of buttermilk. Choose a portion size you use regularly in your recipes. Ladle the portion into the freezer bag.
  3. Seal
    Squeeze out any excess air and seal the bag so that it is airtight.
  4. Place Onto Baking Tray
    Lay the buttermilk and freezer bag flat onto a baking sheet and flatten. Do this with every portion of buttermilk you have.
  5. Freeze
    Once you have all of your buttermilk in bags and laid flat on the baking sheet, pop the whole thing, including the baking sheet, into the freezer. Make sure you have space to keep the baking sheet flat and allow the buttermilk packets to freeze for a few hours.
  6. Remove From Tray
    Once they have frozen you can remove the baking sheet and pop the frozen buttermilk back into the freezer.

How to Freeze Buttermilk In Muffin Trays

If you only use small amounts of buttermilk in recipes then you can freeze them in handy portions that you can grab out whenever you need.

Each section of a deep muffin tray will hold about a quarter of a cup of buttermilk – the perfect amount for most recipes.

  1. Ladle Portions Into Muffin Tray
    Grab a silicone muffin tray and ladle a portion of buttermilk into each section. Make sure you leave a gap at the top to allow for the buttermilk to expand as it freezes.
  2. Freeze
    Put the muffin tray onto a baking sheet so you can easily keep it flat and then pop it into the freezer.
  3. Remove from the Freeze
    Allow the buttermilk to freeze for a few hours then remove them from the freezer.
  4. Bag Up
    Pop the frozen buttermilk portions out of the muffin tray and into a freezer bag.
  5. Freeze Again
    Date and label the bag and put it back into the freezer. You can grab out a portion from the bag any time you need.

How to Freeze Buttermilk Biscuits

If you have already used your buttermilk to bake some delicious biscuits or scones then you can freeze these too! Baked goods freeze well for a few months so you always have a tasty treat to hand.

Simply wait for your biscuits to cool after baking and pop them into the freezer in a labelled and dated freezer bag.

Most baked goods can be frozen in the same way so no matter what recipe you use buttermilk in you can pop them into the freezer for a great packed lunch addition or sweet treat.

3 Tips for Freezing Buttermilk

Now you know how to freeze it, we’ve got our 3 top tips which we strongly recommend following when freezing buttermilk to have the best results:

Consider Your Use
Think about the ways in which you use buttermilk and then freeze it in appropriate containers.

Label It Clearly
Once frozen, buttermilk can look like cream and milk. Make sure you label it clearly so you know exactly what it is you’re defrosting.

Whisk After Thawing
Once thawed, you may notice a change in the texture of the buttermilk. You can rectify this by giving it a quick but vigorous whisk to incorporate the separated fats.

How Long Can You Freeze Buttermilk?

Buttermilk can be kept in the freezer for up to three months. After this, the texture and taste might start to deteriorate too much to be tasty. So make sure you label the buttermilk well so you don’t forget to use it in time.

You Can Freeze Buttermilk for Around 3 Months

How Do You Defrost Buttermilk?

Defrosting buttermilk is easy to do but you do need to be patient because the slower you thaw it out the better. There are a couple of methods you can use when defrosting.

The first method is to take your frozen buttermilk out of the freezer, pop it into a bowl and then put it in the fridge overnight to thaw out slowly. This works well for whichever method you used to freeze the buttermilk.

If you need your buttermilk a little faster then you can pop a bag of frozen buttermilk into a bowl of cold water. Make sure you keep it in the bag or the buttermilk will mix with the water and become a little too watery to use.

If you have frozen the buttermilk flat this shouldn’t take too long to defrost and you can start baking

Can You Refreeze Buttermilk?

We wouldn’t recommend that any food is refrozen in its original state so once you have thawed out your buttermilk make sure you use it within a few hours. If it has been defrosted over a day then it is best to throw it away.

However, not refreezing only applies to the buttermilk in its uncooked state. Once you have used it in your baking you should be able to freeze the baked results with no problems at all.

Does Buttermilk Freeze Well?

Buttermilk isn’t one of those items that freeze perfectly. When it is frozen it does change the texture and might even separate out. A quick blend with a blender or whisk should sort this out and you can mix it up again.

Unfortunately, it will never quite have the same texture again once it has been frozen.

Although buttermilk doesn’t freeze perfectly, once you have blended it and added it to a recipe you shouldn’t be able to tell the difference at all. So make sure you pop any leftover buttermilk you have in the freezer ready for the next time you bake.
