How Long Are Chopped Onions Good For?
Chopped onions are said to be good for only one week or ten days – that too if placed in the fridge. However, make sure that they are covered or wrapped securely. Apart from that, whole onions can last for several weeks without even the need of being refrigerated.
We just covered the practice of making our onions last longer by cutting them, placing them into appropriate containers, and keeping them in your fridge or freezer.
When you keep cooked onions in the fridge, once you put them into appropriate containers, they will stay good for three to five days. Onions can also be stored in the freezer, and the best way to store them is by peeling the top layer first, then cutting or chop onion, then placing them into an airtight container or a heavy-duty freezer bag. When choosing onions, look for ones that are firm, without any soft spots, and completely covered by their skin, which should look papery and dry. Do not choose onions with mold, discoloration, bruises, cuts, or any strange odors. The best way to store whole onions is in a cool, dark, dry place, where they can last for up to two months. Ideally, onions should be stored in a cool, dark area that is 45-55 degrees Fahrenheit. Raw, whole onions will last for two or three months if stored in a cool, dry area.
| Storage | Shelf Life |
| Pantry/Kitchen counter | 1 week |
| In the refrigerator | 10-14 days |
| Freezer | 2 months |
If you cannot make it to last, whole, raw onions should be refrigerated for the best shelf life. Whole, raw onions will last for up to 2 months in the refrigerator. That is, if you do not have room for a refrigerator, and keeping onions at room temperature is the only option, whole, raw onions will last for two to four weeks at room temperature. If you do not have a pantry, basement, or even garage, onions are best stored in a refrigerator, where they will last for up to two weeks, or at room temperature, where they will last for about a week. While onions will last for a month or longer if stored correctly, you can buy extra time by freezing them.

Whole onions typically last for six weeks when stored on the counter, but they can last for two months if stored in the freezer. In general, onions should last seven to 10 days in the fridge, and six to eight months in the freezer, but it can all depend on how you store them. If you store onions at room temperature (like the pantry), they will last around two or perhaps three weeks during warmer months, and around one month during cooler months.
If you store them in a vented basket in your kitchen or pantry, they last half that time. As long as you intend to be cooking onions, not using them raw as a flavoring or seasoning, where texture is key, you can keep them frozen for months. Once onions are peeled or chopped any way, they are best stored in a sealed bag or container in the fridge. Onions have the longest shelf life when chopped or cut into pieces and stored in an airtight container and then placed in the fridge.

It is recommended that you keep your chopped onions in a sealed container or plastic bag when you are in the fridge. The same rules of storage should be applied when freezing onions, meaning that you should put them into a sealed container or plastic bag before placing them into your upright or chest freezer. Spring onions also have a higher water content than other onions, so a better storage method is in a sealed plastic zip-lock bag in the vegetables section of the fridge. It is also critical that you store your uncut onions in a mesh bag or an open basket instead of plastic bags, as plastic bags lack proper ventilation, which will help your onions last longer.
If you have a pile of onions in storage, check on them every couple days and throw away any that are starting to spoil. If you want to ever store fresh, uncooked onions for a longer period, you also need to slice, slice, or chop them before storing. With proper preservation, cut, cut, or diced onions can last in your refrigerator for up to 20 days.
If you really want a constant supply of slices, cut or diced onions for soups, casseroles, and stews, you may want to opt for freezing your slices, which will keep them in tip-top condition for three to six months. When following proper food preservation guidelines, scallions keep up to two weeks inside your refrigerators crisper drawer.

Half-cut onions will last in the refrigerator no longer than 2 weeks, but degradation can occur much more quickly depending on the variety of onions. Use all of your chopped onions within six to 10 days after chilling, unless you choose to experiment with the Pickled Onions recipe. Onions also keep in the refrigerator for at least two to three months — just keep in mind their texture can become slightly soft when they are cold, since onions soak up moisture so easily. We already covered how to store cooked onions, so we are going to cover the other forms of onions as well and reliable ways of storing them to keep them as fresh as possible.
While there are ways to be creative with leftover onions (caramelizing them, for instance, or combining with bell peppers and onions), we usually fall into the habit of saving a half of an onion, or a sliced/chopped onion, for later. When using fresh onions, we keep unused parts for up to a week in our refrigerator, either in ziploc bags or in sealable Rubbermaid-style containers. Most bags of onions, and those that come in a grocery store bag, are happier stored in a cool, dry area, away from light, ideally (these are the storage onions — just regular red, white, and yellow ones).
