Leeks Top tips

How to freeze and defrost

To freeze: Leeks can be frozen! Simply slice and freeze them on a tray, before popping into a sealed container.

To defrost: When you take food or drink out of the freezer, it’s important to defrost it safely. Don’t defrost at room temperature.

Ideally, defrost fully in the fridge and use within 24 hours. Or, use a microwave on the defrost setting directly before cooking or reheating.

Eating the whole food

Use the green ends of leeks the same way you would the white part. Just wash thoroughly.

Be fabulous with leftovers

Leftover fresh leeks

Leftover leeks are a great addition to a vegetable soup or a cheese sauce.

Leftover cooked leeks

You can add cooked leeks to mashed potato or use to top cottage pie.

Buying tips

Think about buying leeks loose to help you buy only what you need. This will ensure that all your food is more likely to be eaten and saved from the bin.

Think about swapping fresh leeks for chopped, frozen ones. Frozen foods last a long time in the freezer, you can use as much as you need when you need to and they can often be a cheaper option.
