It’s common to store vegetables in the refrigerator to extend their life. But can you store onions in the refrigerator?

Yes, you can store onions in the refrigerator. However, it’s not the best way to store onions. Refrigerating onions will extend their shelf life by at least a week, but the moist environment will change their texture. It’s better to store onions in a cool, dry, and dark place at room temperature.

Let’s understand this in a bit more detail.

How Long Do Onions Usually Stay Fresh?

Unlike other produce that spoil quickly, onions remain fine for a very long time.

This is one of the reasons why you can buy onions in bulk. It’s both cost-effective and practical.

When stored properly, onions will stay fresh for at least a month.

However, improper storage and exposure to moisture can spoil them. When onions rot, they smell terrible and stink up the whole place.

Onions hold up well in cool, dry, and dark storage spaces with good air circulation.

You can keep them in an open plastic bin or basket in a suitable location, and they will keep well.

At room temperature, onions remain fresh for several weeks.

Under ideal conditions where the storage temperature is between 45°F and 50°F (just above refrigeration temperature levels), they may even last for up to a year.

So you can safely put them in a dark and dry corner of your pantry or kitchen, and they will be fine.

However, any exposure to moisture or light can cause rotting or sprouting. Moisture can also spoil onions and emit foul, moldy odors.

How Long Do Onions Remain Fine In A Refrigerator?

The refrigerator is the best place to store most produce. However, it’s not ideal for storing onions.

They would do better when stored at room temperature. Nevertheless, you can put onions in the refrigerator.

By refrigerating onions, you can extend their shelf life by a week or more.

Nevertheless, the cold and moist environment of a refrigerator can alter their structure. Refrigerated onions tend to absorb moisture and become soggy.

How long onions keep in the refrigerator depends on the type of onion and how you store it. Most varieties last for up to two weeks when refrigerated properly.

However, whole, raw onions last for less time than peeled or sliced onions. Sliced onions stay good for a week to ten days.

Cooked onions will last only a few days, much lesser than raw onions.

If you must store onions in a refrigerator, it’s best to peel them and store them in an airtight bag or container.

Can You Store Uncut Onions In The Refrigerator?

Although you can store whole unpeeled and uncut onions in the refrigerator, it’s not a good idea.

If you look closely, you will see that store-bought onions have thin, papery skin. This is because onions are cured after harvesting.

So when you expose these onions to moisture, the dehydrated skin absorbs moisture. Water makes the onions soggy, soft, and prone to spoilage.

When you store store-bought onions in the humid environment of a refrigerator, they absorb moisture and become mushy. It increases their chances of spoilage.

The better option is to store them outside the refrigerator at room temperature.

Alternately, you can also peel the onions before putting them in the refrigerator. Peeled onions will last for seven to ten days in the refrigerator.

Can You Store Peeled Onions In The Refrigerator?

If you have no other option but to store onions in the refrigerator, it’s best to peel them before placing them in the refrigerator.

The thin, papery skin of onions soaks moisture when exposed to humidity. This makes them moist and soggy, thus increasing the chances of spoilage.

To avoid this issue, peel the onions first. Remove the papery skin and transfer the onion into an airtight container or bag before putting them in the refrigerator.

Peeled onions will keep for up to two weeks when stored properly.

But if you slice or chop the onions, they will not keep for long. Use them within a week to ten days to avoid any risk of spoilage.

How To Identify A Spoiled Onion?
