“Can buttermilk be frozen? How do I freeze and store buttermilk? How long is it good for? Let’s dive into these common buttermilk questions!”

How many times have you gone to make a recipe that requires buttermilk and you are fresh out of it? It happens to me often. Thank God for buttermilk substitutions, but let’s face it, there is really nothing like that creamy, thick, buttery-tart tasting buttermilk, the real deal!

How To Freeze Buttermilk

It makes cakes and biscuits so moist and makes for the creamiest homemade salad dressings. There is no doubt about it, buttermilk is definitely one of my favorite ingredients. Judging from how often I throw it into my recipes on this site, I’m pretty sure you’ve figure that out by now : )

So to ensure that I don’t run out of my precious buttermilk I’ve started freezing it! Normally it would sit in the fridge and go bad, but now after I make a recipe I freeze the rest of it.

How do you freeze buttermilk?

Ice cube trays!! Yep, first measure out 1 cup of buttermilk. Then pour that cup into the ice cube trays. Now you know how many cubes equal a cup. Write this on the front of a gallon freezer bag so you’ll know in the future how many cubes to thaw out.

Freeze and then you’ll have fresh buttermilk on hand whenever you need to make a batch of buttermilk pancakes at the last minute! Let me tell you, it comes in handy!

How do you thaw frozen buttermilk?

To thaw out, I nuke it in the microwave in short intervals or let it thaw out in the fridge overnight. Another quick way to thaw it out is to place the cubes in a sealed sandwich bag and submerge the bag in hot water (helloo breastfeeding days oh how I do not miss thee)

Be sure to stir or whisk vigorously  after it has thawed since it tends to separate a bit. It may not be as creamy as it once was when it was in it’s fresh, pre-frozen state but it works just as good!  Kinda like going from your 20’s and into your mid 30’s and 40’s. You may not look the same but you can still get the job done- OKAY!

How long does buttermilk last?

Fresh buttermilk in the fridge lasts about 2-3 weeks after opening it. Don’t be tempted to use old buttermilk thinking “well it’s sour milk anyway” (This is so my grandmother) After the expiration date old buttermilk begins to lose it’s buttery flavor and aroma and becomes bitter and off tasting.

How long does frozen buttermilk last ?

Frozen, fresh buttermilk can last about 3 months. I confess to using my cubes past this mark though when I vacuum seal them.

Ok so go look in your fridge and see if you have any buttermilk, check the expiration date and if it’s still some good, FREEZE IT!!!!
