Have you been storing your onions incorrectly all along? Confusion Cleared by Food Experts!

An onion is one of the most useful ingredients you can keep in your kitchen. Their flavor can be enhanced in soups, sauces, and so much more. However, onions don’t last forever, and if you don’t store them properly, they can go bad quickly.

How about the good news?  You can keep your onions fresher for longer by following a few simple storage tips. Check out these culinary pros’ tips for storing onions.

What is the shelf life of onions?

Let us start with the basics: How long do onions last? A culinary dietitian from Charlotte, North Carolina, Melanie Marcus, RD, says whole raw onions can retain their quality for three to six months, depending on storage conditions. Cooked onions, however, usually last three to four days in the refrigerator if they are stored properly.

What you need to know about storing whole onions!

Depending on the type of onions you have, you should store them differently. Do you have a bunch of whole raw onions? It is advised by the National Onion Association to store onions in cool, dry, well-ventilated areas such as a pantry or cellar, ideally with an average temperature of 45 to 55 degrees Fahrenheit, according to Elizabeth Shaw, RDN, president of Shaw Simple Swaps. “They also recommend avoiding placing onions in a bag or with other produce that releases moisture as both practices will reduce their shelf life.”

According to the National Onion Association, whole onions can last up to 180 days when stored properly in the fall and winter, and up to 60 days in the spring and summer.

According to Marcus, it is best to put whole onions in a mesh bag or wire basket (not plastic). Also, don’t refrigerate whole onions with the peel because “this will allow moisture from the fridge to penetrate into the paper layers and accelerate decomposition.” To keep them dry, wrap them individually in newspaper or paper towels if you have to store them in the refrigerator to keep them cool.

The best way to store cut onions!

Now that you know how to store whole onions, what about peeled and cut onions? In case you’re wondering how to store cut onions, here’s a good tip: “Peeled and cut onions should be stored in an airtight container in the refrigerator for seven days,” advises Marcus. If you want to store cut onions, make sure your refrigerator is set to 40 degrees Fahrenheit or below.

Here is how to store green onions!

Shaw recommends storing green onions in the fridge under 40 degrees Fahrenheit for best quality if you want to use them as a garnish for pasta, soup, or salads. I like to discard any outer parts of the green onion that are past their prime, then rinse it under cool water, pat it dry, and wrap it in paper towels for easy storage in the refrigerator’s produce drawer.

Marcus, meanwhile, offers this advice: “Treat green onions the same way you would fresh herbs.” Place the root end in a glass of shallow water, then cover it with a plastic bag to keep the moisture in. Also, you can store them in the fridge in a zip-top bag with a damp paper towel to maintain moisture.”

The Best Way to Store Potatoes and Onions!

Have you ever wondered how potatoes and onions should be stored? We hate to break the bad news, but you shouldn’t store them together. “Onions should not be stored with potatoes or other vegetables because they contain moisture and may make the onions rancid faster,” says Shaw.

Whenever onions and potatoes are stored close to each other, onions emit ethylene gas, which causes potatoes to ripen quickly. Potatoes, on the other hand, have a high moisture content, which makes onions go bad when stored together. It is important to provide ample space and air flow when storing them in order to prevent them from spoiling. In close proximity to onions, raw potatoes will absorb their smell, which will be reflected in their flavor when cooked.

The Best Way to Store Cooked Onions!

Cooked onions require different storage methods than raw onions. The best way to store cooked onions is to store them in an airtight container in the refrigerator for three to four days.

What is the best way to freeze onions?

Yes, raw onions can be frozen to extend their shelf life. The onion should be rinsed under cool running water, drained, and cut into pieces after being patted dry. Place them in an airtight container or resealable bag after they have been cleaned In order to absorb moisture, “I personally like to place a paper towel inside the bag.” she says. Lastly, label and date the bag and use the raw, uncut onions within a month.

Marcus offers this tip for freezing raw, chopped onions: “Spread chopped onions on a baking tray in a single layer.” Place in the freezer for at least an hour before transferring to a zip-top bag. You can keep them in the freezer for three to six months.”

An easy way to tell if onions are bad!

When an onion is past its prime, it’s pretty easy to tell. First and foremost, Shaw says, you should be able to tell by the smell. “If it smells foul or off, compost it or throw it away,” she says. The onion should be thrown out if there is visible mold or it feels tender, squishy or slimy when you peel it back. If you want to know if an onion is still good, feel it with your fingers; it should be firm and not soft.
