Do onions go in the fridge?

No, onions do not go in the fridge. Onions are one of the few fresh ingredients that are not recommended to be stored in the fridge as cold temperatures can severely affect the quality of the ingredient.

As onions have the outer layer dried, the humidity of the fridge will not have good consequences. The best place to store onions is in the pantry, where you can keep them in a cool, dark, and dry place.

What are the effects of refrigerating onions?

Onions are a staple in everyone’s kitchen as they are used to prepare most dishes, and trust me when I say onions add that last touch to your food. They can be consumed cooked, grilled, pickled, or chopped. What is your favorite way to eat onions?

All over the world, onions have a major role in the gastronomic field, but do you know what is the best way to preserve their taste for longer? Onions should not be stored in the fridge unless they are peeled, as this can cause most of their features to be affected. 

But why is that? Well, when onions are submitted to a cold and humid environment, the starch will be converted into sugars that will cause quicker spoilage. However, if you have ever stored onions in the fridge you know they spread their odor to any ingredient near them.

So, if you want to avoid mushy onions and your yogurt tastes like onion, you should stop refrigerating them.

How do you need to store onions?

Onions are composed of several layers that need to be kept away from cold temperatures and damp environments. The best space to store onions is one that ensures all of the following features

  • Cool place. But not as cool as the fridge, experts say that the best temperature to store onions are between 45 to 50° F. If you can not store them at this temperature, leaving them at room temperature can also work.
  • Dry space. The humidity will cause onions to go bad quickly and acquire a mushy texture that is not appetizing at all!
  • Avoid keeping your onions in a plastic bag. This will leave them without any air to breathe and they can spoil quickly.
  • Do not store onions near potatoes. When potatoes are stored, they tend to liberate moisture, which can cause rapid spoilage of onions, as we have already discussed.
  • Are you tired of crying when chopping onions? Well, you can reduce the sulfur compounds responsible for the tears by letting onions chill 30 minutes before using them. If you want further guidance on this subject, you can click here

Can you freeze onions?

Freezing onions can be really useful to avoid wasting all the leftovers, and they can still be used to prepare cooked dishes, like casseroles, soups, or stews. But you do need to attend to several recommendations to avoid any side effects

  • First, pick mature onions to freeze.
  • You need to peel them and then clean them with the help of a scrub.
  • You can freeze chopped or diced onion, there is no problem, but make sure you do tiny fragments to permit better freezing.
  • Now, you only need to place your chopped onions into freezer bags, squeeze out all the air, and seal them. Try to avoid them clumping to guarantee an easier use for recipes.

Also, most dishes will not need onions to be fully thawed, so do not stress out about it.

How long do onions last?

Whole onions exhibit a large life, compared to other fresh goods, they can last for up to 1 to 3 months, or even longer! It all depends on the effort you put in when storing them. 

If you have chopped or sliced onions, their shelf life will be reduced to only 4 to 7 days.

Also, if you do not use them shortly, you must check for any spoilage signs, when one onion has started rotting, the other ones will be affected as well.

How can you tell when onions have gone bad?

Spotting rotten onions is not rocket science, in less than 1 minute you can tell if you can still use them! Make sure you check for these signs before using a stored onion, even more, if they have been sitting in the pantry for a long time.

  • Choose onions with a firm texture.
  • Avoid the ones with sprouts.
  • Check for any dark spots.
  • Discard slimy layers.
