Can You Freeze Plain Yogurt?

Freezing plain yogurt is really a decision to trade its smooth texture for shelf life, and it's worth making that trade deliberately rather than by accident — a container frozen specifically for a future smoothie is a good call, while a forgotten tub pulled out months later expecting a spoonable snack will be disappointing. Small portions frozen in an ice-cube tray or muffin tin thaw faster and let you use exactly the amount a recipe calls for. The grainy texture that develops on thawing comes from the same protein structure breaking down that also happens to cream and sour cream once frozen — a physical change, not a sign anything's wrong with the yogurt.

Freezing does reduce some of the live active cultures yogurt is often bought for in the first place — the bacteria don't all die from the cold, but their numbers drop somewhat through a freeze-thaw cycle, worth knowing if the specific reason for buying a cultured yogurt was its probiotic content rather than just its flavor or protein. The thin liquid that naturally separates on top of an unfrozen tub is routine and stirs back in easily, a different matter from the more thoroughly separated, grainy result a thawed and previously frozen tub produces, which no amount of stirring fully restores. Whole-milk yogurt tends to hold its texture slightly better through freezing than a nonfat version, since the extra fat provides a bit more structure for the protein network to lean on as ice crystals form.
