Can You Freeze Milk?
Written by Jordan Morley · Reviewed against USDA FoodKeeper · Last updated 28 October 2026
Yes, you can freeze milk. Best quality within 3 months; it stays safe beyond that at a constant -18°C.
What freezing does to milk
Milk freezes safely, and it is one of the few fridge staples worth freezing to cut waste: at -18°C the bacteria stop multiplying. The fat can separate when it thaws and the texture may be slightly grainy, but a good shake or a blitz with a stick blender fixes most of it, and it is fine for tea, cereal, cooking and baking. FoodKeeper gives milk a best-quality freezer window of 3 months. For comparison, the same database gives butter 6–9 months, double cream 3–4 months, yoghurt 1–2 months.

How long can you freeze milk? Two rivals, two answers
| Source | Freezer time | Notes |
|---|---|---|
| Tesco Real Food | Up to 3 months once frozen solid, but 'it's wise not to freeze milk for more than 1 month' | Shorter for better texture |
| Healthline (updated 15 Oct 2026) | Up to 6 months, with about a month suggested for best quality | US site |
| USDA FoodKeeper (this page) | 3 months for best quality | Quality, not safety |
The figures are about texture. At a constant -18°C frozen food stays safe. Our practical call is to use frozen milk within a month or two.
How to freeze and thaw it
- Pour some milk out first. Milk expands as it freezes, so leave head space (Tesco suggests about 1½ inches at the top of a bottle).
- Use a freezer-proof plastic container and label it with the date.
- Thaw in the fridge overnight. For speed, stand the bottle in cold water and change the water after 30 minutes (Tesco). Healthline says never use warm or hot water, and Tesco says avoid the microwave and room-temperature thawing.
- Shake or blend before use: freezing 'can make your milk separate and go grainy' (Tesco).
How long it lasts once thawed
Tesco says frozen milk keeps for as many days as it had left before its use-by date when it went into the freezer. So milk frozen on its last day has about a day once thawed. Healthline does not give a thawed-milk window. We could not find a UK government figure, so treat the label date as the starting point and use thawed milk within that window and in cooking or tea if the texture is off.
Which milks freeze badly
Healthline says almond, soy, oat and dairy milk may all separate or turn grainy, and that canned coconut, evaporated and sweetened condensed milk should not be frozen in the can; sweetened condensed milk will not freeze solid. It does not cover whole versus skimmed.

Does milk go grainy when frozen?
It can separate and turn grainy; shaking or blending usually fixes it (Tesco). It suits tea, cereal and cooking.

In the fridge overnight. Cold water works faster if you change the water after 30 minutes. Avoid the microwave and the counter.
How long does thawed milk last?
Tesco says as many days as it had left before the use-by date when you froze it. We found no UK government figure.
Do I need to leave room in the bottle?
