Onions are a popular veg used in many savoury dishes. They are part of the allium class of the lily family along with leeks, garlic and chives and come in different shapes, sizes, flavours and colours including spring onions and red and white onions. They add a depth of flavour to recipes such as soups, stews and currys, and can also be eaten raw in salads. They are full of goodness including vitamin C and fibre.

How to store

How to store fresh onions

Only spring onions should be stored in the fridge. Brown, red and white onions are best stored in a cool, dry, dark place, ideally in a cloth bag.

Freezing onions

Onions can be frozen in a sealed bag or airtight container for up to 3 months.

Storing cooked onions

Store in an airtight container in the fridge for up to 2 days.

How to freeze and defrost

To freeze: If you only need half an onion, chop up the rest and freeze to save time when you next need to cook in a hurry - they can be cooked straight from frozen.

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.

Use from frozen in your cooking or use a microwave on the defrost setting directly before cooking or reheating.  Always check the on-pack guidance for frozen foods.

Eating the whole food

Spring onions: There’s no need to stop chopping when you get to the green bits of spring onions - the green ends of leeks and spring onions are full of flavour and perfectly edible. Use them in the same way as you would the rest of the onion.

Be fabulous with leftovers

Add leftover onion to a stock bag and freeze along with celery and carrots as a flavourful base ready for soups, stews and pasta sauces. Finely slice (or grate) raw cabbage, carrots and leftover onions and mix with mayonnaise for a quick and easy homemade coleslaw.

Buying tips

Think about buying onions 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 onions for chopped, frozen ones (no tears!) 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.

Buy smaller onions as they’re often cheaper and there’s less waste if you’re cooking for one person.
