They can be stored in an airtight container for roughly three to five days. Similar to regular onions, shallots should be stored in a cool, dry, dark, and well-ventilated place, as a lack of air circulation will reduce their shelf life, says Massachusetts-based registered dietitian Kimberly Greene Murachver , R. You can store them in a mesh bag, wire basket, or even pantyhose to maximize air circulation and keep them fresh as long as possible. Place them loosely into a plastic bag before storing the onions in your crisper drawer.
Because they have a higher water content, chives are the most delicate of the bunch and have a shorter shelf life. If using within a few days, you can stand them up root ends down in a jar that contains a few inches of water and cover them loosely with a plastic bag before popping them into the fridge, says Aguirre. You can also store them in a resealable plastic bag, with the air still inside to prevent excess moisture from spoiling them , for up to one week.
By Krissy Brady October 24, But because their signs of spoilage aren't as obvious as that of some other vegetables, you may be keeping your onions well past their prime and not even know it. Learn exactly how to store onions, and how long you should go before you toss them.
Here's how long onions last, provided you're storing them correctly. Ideally, onions should be stored in a cool, dark place between 45 and 55 degrees F. Whole, raw onions will last two to three months when stored in a cool, dry place. Places that provide these conditions could include a cellar, pantry, unheated basement, or garage. But for many of us, it's a challenge to find a cool spot like this in our homes. If this is the case for you, you're better off storing onions in the fridge for maximum shelf life.
But if you lack fridge space and storing onions at room temperature is your only option, whole, raw onions will last for up to a week at room temperature. When storing onions, whether at room temperature or below, be sure to provide proper ventilation to prevent molding. An open basket, mesh bag, or loosely covered paper bag will do the trick.
Do not store onions in a plastic bag, as this will not allow for proper ventilation. While the fridge isn't ideal for storing onions, it will extend the shelf life of whole, raw onions beyond a week at room temperature.
Onions absorb moisture very easily however, so their texture may get somewhat soft in the fridge. Click here to find this airtight onion keeper on Amazon. For an unpeeled onion, refrigeration is not the best option. Cooling creates a moist, but cold, environment to inhibit the growth of bacteria. This environment causes onions to soak up too much moisture, becoming mushy and spoiling quickly.
It is best to keep unpeeled onions out of the refrigerator. The best place to store whole onions is in a cool, dry place with a temperature between degrees Fahrenheit. This area should also be well ventilated, to ensure onions stay as fresh as possible for as long as possible!
Either a pantry or cellar location in a home meets these requirements. Both locations are typically cool, dry, and well ventilated to prolong the life of onions.

If it is cut or sliced, use an airtight container to store onion in the refrigerator.
Refrigerated, cut onion will last for days because a cool, airtight environment is optimal to prevent bacterial growth and spoilage. Again, use an airtight container because it will contain the odor produced from the onion. An airtight container also reduces the amount of moisture the onion is exposed to, so the onion does not get mushy and spoil.
If you have a whole, unpeeled onion, then refrigeration is not recommended. This is because refrigeration contains a significant amount of moisture, which the onion absorbs. Extra dampness inside the onion will cause it to spoil faster. There are multiple options to be able to store onions for a month or longer. The first option is useful for uncooked onions, by storing them in a cold, dry room. You can also use proper ventilation techniques, discussed later, to extend the life of whole onions past one month.
The second option is to freeze the onion. Make sure to remove as much moisture as possible from storage container. Removing moisture will ensure the onion will not be too mushy for a decent cooked result in the future. If you are looking to store onions for an extended period, make sure to not utilize plastic wrap or store onions in plastic bags. Plastic wrap and plastic bags reduce ventilation for the onion, meaning the onion will spoil much faster.
Prolong onion storage beyond a month by freezing.
