Yes — you can freeze milk.

Yes, you can freeze milk, and it’s a handy way to avoid waste if you’ve over-bought or you’re going away. The main thing to remember is that milk expands as it freezes, so you need to make room in the container first. Frozen and thawed milk can separate a little and turn slightly grainy, so most people prefer to use it for cooking, baking and sauces rather than in a cup of tea.

How to freeze it

Freeze it fresh, well before the use-by date. Pour a splash out to leave room for expansion, then freeze — either the whole container or in smaller portions and ice-cube trays for adding to recipes. Thaw it in the fridge and give it a good shake to bring it back together.

How to freeze milk

  1. Freeze milk before its use-by date, while it's still fresh.
  2. Pour a little out first — milk expands as it freezes, so the container needs room.
  3. For handy amounts, freeze it in portions or an ice-cube tray for tea and cooking.
  4. Seal well and label with the date.

How long it keeps

Up to 3 months for the best quality.

How to defrost

Thaw in the fridge overnight — never at room temperature — and use within a day or two.

How to reheat

No need to reheat; use cold once thawed.

When not to freeze it

  • Don't freeze milk in glass bottles — they can crack as the milk expands.
  • Whole and semi-skimmed can separate or turn slightly grainy; it's fine for cooking and baking but you may prefer fresh for tea.

Food safety: Always thaw milk in the fridge, not on the worktop, and keep it chilled. Use thawed milk within a day or two, and don't refreeze it.
