Yes! Will there be a loss in quality? Depends—but in general, it’s worthwhile.
What Kind of Milk Can You Freeze?
You can freeze any kind of dairy milk: skim, 2%, whole milk, even cream. The higher the fat content, the more the milk will change after thawing (the fat will separate out), but a good shake post-thaw will fix it for more uses. What about non-dairy milk? Yes, you can freeze non-dairy milk. It, too, will separate when thawed but should come together after shaking.
How to Freeze Milk
For the least freezer-y taste, use the milk within 3 months of freezing.
How to Thaw Frozen Milk
Thaw frozen milk in the refrigerator. Depending on the volume, milk can take 8 to 48 hours to thaw. If you froze it in a carton or jug, put a plate or tray underneath to catch any liquid, just in case there’s a new leak in the packaging.
How Milk Changes After Freezing
If the frozen milk has a higher-fat content, the fat may separate out once it’s thawed. It’s not a thing we’re used to seeing with homogenized milk and can be off-putting if you’re planning on using it by drinking the milk or pouring it on cereal or in coffee. To remedy this, shake the milk right before using it or blend briefly with an immersion blender.
