Can you freeze whole milk?

Quick answer

Yes, university extension services say pasteurized milk can be frozen. Expect some separation or graininess after thawing; stirring or shaking helps. Leave room in the container because milk expands, and thaw it in the refrigerator.

How do you freeze whole milk?

Mississippi State University Extension advises removing an inch or two of milk from the container before freezing to allow for expansion. The University of Nebraska-Lincoln (UNL) says to freeze milk in small containers and leave extra space at the top. Mississippi State also suggests individual-serving containers or ice cube trays for small amounts used in cooking.

How long can you keep frozen milk?

UNL says to use frozen milk within a month for best quality. Mississippi State gives no freezer time, only to freeze products before their expiration dates. Neither page gives a separate rule for whole (full-fat) milk; UNL refers to pasteurized milk in general.

Does frozen milk taste the same?

Some people find that freezing changes the flavor, according to Mississippi State, which advises testing a small amount first if you plan to drink it. UNL says frozen milk works best for cooking, though it may still be fine for drinking. Mississippi State also says freezing does not change the milk’s nutritional value.

How do you thaw it, and why does it separate?

Both universities say to thaw milk in the refrigerator. Mississippi State explains that fats and proteins thaw faster than the water, so the milk separates. Shake it or whisk it to bring it back together, then use it right away. UNL says thawed milk may be slightly grainy.

Can you refreeze milk?

North Dakota State University Extension groups milk with dairy products that should be thawed in the refrigerator and not refrozen.

People also ask

Can you freeze full fat milk?

Yes. The extension pages we read cover pasteurized milk in general and do not give a different rule for full-fat milk. Leave headspace, thaw in the fridge and shake well.

Can whole milk be frozen and still be used for drinking?

UNL says frozen milk works best for cooking but may still be okay for drinking. Mississippi State says some people notice a flavor change, so try a small amount first.

How much room should you leave when freezing milk?

Mississippi State Extension says to remove an inch or two of milk from the container before freezing; UNL says to leave extra space at the top because milk expands.
