Yes, you can freeze milk for several months. However, it's best used within one to two months of being frozen to maintain texture.
Freezing causes milk's components to separate, resulting in a grainy texture upon thawing. A good shake can restore some of the original consistency.
Skim and low-fat milk freeze best as they separate less upon thawing. Higher fat content milk will show more separation.
Freeze milk in its original plastic container, leaving a gap at the top for expansion. Glass or cardboard containers are not suitable.
For small quantities, freeze milk in ice cube trays. These can be added directly to sauces, iced coffee, or smoothies.
Thaw milk in the fridge overnight or submerge the container in a bowl of cold water. Never thaw milk at room temperature.
Non-dairy milks like almond, oat, and soy milk can be frozen but may become grainier. Use them in smoothies or cooking.
