Learn all the tips and tricks for Freezing Buttermilk to save money and prevent food waste. A stash of frozen buttermilk can be used for breakfast recipes, dressings/sauces, and baked goods, and it makes a fantastic marinade!
Buttermilk is a super versatile ingredient, but sometimes you can’t use the whole container before the expiration date.
Sure, there are buttermilk substitutions out there, but sometimes you just want the real stuff without having to run to the store.
With just a few simple tricks, you can build a freezer stash of frozen buttermilk to use in so many delicious recipes.
Can You Freeze Buttermilk?
Yes! Thanks for the high-fat content in buttermilk, it freezes incredibly well.
Once thawed, you may notice some separation but a quick whisk by hand or an immersion blender will return it to a perfectly useable state. It won’t be as thick as it was when it was fresh, but you’ll still get that great buttermilk taste.

There are a lot of different containers you can use for storing frozen buttermilk. I prefer jam/jelly jars (4 or 8 oz) Souper Cubes (1/2 cup or the 2 tbsp size are my favorite), ice cube trays, freezer bags, or muffin tins.
Freezing buttermilk in Ice cube trays/Souper Cubes/Muffin Tins
Pour buttermilk into your tray of choice. I prefer 1/2 cup or 2 tbsp size trays because they allow you to easily measure how much buttermilk to defrost for recipes.
Transfer the trays to the freezer and allow them to freeze until hard (~2-4 hours). Once frozen, remove the cubes from the trays and transfer them to freezer-safe storage.
Freezing Buttermilk in Canning Jars
To freeze buttermilk in canning jars, select clean wide-mouth jars. Allow for 1 inch of headspace (the space between the top of the liquid and the top of the jar) to give everything room to expand in the freezer.
Freezing buttermilk in freezer bags
If you’re short on freezer space, freezing in sandwich or quart-size freezer bags works exceptionally well. You can fill the bags, secure them, and lay them down on a baking sheet or plate, and freeze them flat. Once frozen, you can store them stacked to save space.
How to Use Buttermilk
I love to keep buttermilk on hand for making Whole Wheat Pancakes, Healthy Banana Chocolate Chip Muffins, Whole Wheat Waffles, Yogurt Ranch Dressing, Whole Wheat Blueberry Muffins, Apple Pie Pancakes, or Strawberry Biscuits.
Buttermilk is also perfect for making Stuffing Biscuits, Air Fryer Popcorn Chicken, Air Fryer Cornbread, and Crispy Air Fryer Green Bean Fries.
Frequently asked questions
You can keep frozen buttermilk in a conventional freezer for up to three months, or 6-12 months in a deep/stand-alone freezer.
If freezing in jars, you can defrost at room temperature for a few hours by placing it in a bowl of cool water. Alternatively, you can put it in the fridge overnight. Do not microwave frozen jars as they could crack.
If you froze in muffin tins or ice cube trays and stored in freezer bags, you can defrost directly in the freezer bag placed in a bowl of cool water. Additionally, you can microwave the cubes on low power in a microwave in 30 second bursts.
You could use the original packaging as long as there is a secure way to close the lid and the container isn’t completely full.
You need to allow space for the buttermilk to expand as it freezes.
Pro Tips/Recipe Notes on Freezing Buttermilk
- To prevent waste, freeze the buttermilk in portions that you know you’ll use for favorite recipes. Once you have defrosted it, you’ll need to use it within two days.
- If you know you’ll need to defrost your portions quickly, it is best to freeze them in smaller portions so they’ll melt faster.
