How to Store Onions

Onion is an ingredient we use in many meals. If it’s stored correctly, it can remain fresh for up to 3 months or up to 6 months if you keep it in the freezer.

5-Minute Crafts shares recommendations on how to store whole, halved, and cut onions. We will also tell you about which kind of onion is good for freezing and how to do it correctly.

How to store whole onions

Store whole onions in a cold, dry, dark, and well-ventilated place. For example, in a closed kitchen cabinet. Don’t put them into the fridge: the onions will absorb the extra moisture, get soft, and go bad faster.

Don’t keep the onions in a plastic bag or a thick fabric bag. It’s better to use a net or a box with holes to let the air circulate.

Whole onions can be stored for 2 to 3 months.

How to store halves of onions

If you have half an onion after cooking, put it into the fridge.

  1. Wrap the piece in food film.
  2. Put it into a thick bag with a zipper or a sealed container.
  3. Use this onion only for making hot meals. It might lose its taste features, so it’s not recommended to eat fresh.

You can store half an onion this way for up to 2 weeks.

How to store cut onions

Store cut onions in a sealed container without film. Use them as fast as possible: the longer they are in the fridge, the more oxidized they’ll get and the fewer vitamins they’ll have.

You can store cut onions for 7-10 days.

Can you freeze onions?

Like many other foods, onions can be frozen. But don’t put whole onions into the freezer. It’s better to cut them or put them in a plastic bag with a zipper or a sealed container.

Before freezing, make sure you’ve removed all the extra moisture and air from the bag or container. It can prolong the life of your onions.

You can store the onions for up to 6 months.
