Can You Freeze Buttermilk to Use Later?

Buttermilk is a tangy cooking and baking staple that gives your pancakes, biscuits, dressings, and other goodies a signature touch of sour flavor. But if your recipe only calls for a little buttermilk—and you're not planning a big buttermilk pancake breakfast—you may have leftovers that could go bad before you use them. So you may wonder whether you can freeze buttermilk, and how to do that safely.

Follow this advice to avoid wasting a single drop of buttermilk—and always have some on hand whenever the urge to make biscuits strikes.

Can You Freeze Buttermilk?

Like other dairy products, buttermilk is just fine to freeze. You may experience a little change in consistency and some separation between the milk liquids and solids when you thaw it out, but it will work perfectly fine in all your buttermilk-based recipes after being frozen.

For the best quality, you'll want to use frozen buttermilk within three months of freezing it. After that it's still safe to use, but the quality may begin to decline.

Tips for Freezing Buttermilk

Freezing buttermilk is a relatively simple thing to do—but using a few key freezing strategies can make it easier for you to use the buttermilk when you're ready to bake again.

You can freeze buttermilk in its original carton

As long as you've used enough of the buttermilk to leave room for your carton's contents to expand when frozen, it's fine to freeze it in the original container. But that means you'll need to thaw all of your frozen buttermilk in one go—and you may not have a use for that much buttermilk the second time around, either.

Consider freezing it in recipe-sized portions

The best strategy for freezing your buttermilk is to think about how you plan to use it—and freeze in appropriate portions. An ice cube tray works great: You can pour the remainder of your buttermilk into an ice cube tray, then once the cubes are frozen, pop them into a freezer-safe bag.

Each compartment is about one ounce (or two tablespoons), so you'd need to thaw two ice cubes per quarter cup of buttermilk in your recipe.

Freeze your buttermilk while it's fresh

Once you know you're not going to get through the whole buttermilk carton, freeze it ASAP to preserve as much freshness as possible. That'll ensure that your buttermilk is at peak quality for your next round of biscuits or pancakes.

How to Thaw Frozen Buttermilk

The easiest way to thaw buttermilk is to put the amount you need into the refrigerator and let it thaw gently overnight. If you're in a hurry, you can also put the buttermilk in a well-sealed container and submerge it in warm water for about 30 minutes, or run water over it in your sink for about 20 minutes. (The larger the container of buttermilk, the longer it will take to thaw.)
