How Long Do Onions Last?

How Long Can You Store Onions?

Whole onions can be stored for up to 3 months in a cool, dry, and dark area, preferably in the pantry, and for 1-2 months in the refrigerator. However, even in ideal conditions, onions will begin to dry up and eventually shrivel if left too long.

How Do You Know When Onions Are Bad?

  • Discoloration: The appearance of black or brown spots on the onion’s outer peel is the first indicator that it is going rotten. This happens when whole onions have stayed too long.
  • Mold: Mold is a classic indication of food degradation, and onions are no exception. On the surface of onions that have been exposed to moisture, mold will form.
  • Odor: Onions, whether whole or sliced, have a distinct odor. When an onion begins to smell bad, it will usually show other indicators of spoilage, such as discoloration, leaking, and a soft texture. In this case, it is time to get rid of those onions.
  • Sprouting and drying: When onions are left in the pantry for too long, they may sprout, but there is no harm in eating them. However, the onion may turn spongy and then shrivel up shortly after sprouting, indicating that it has lost its freshness.

How Long Do Onions Last At Room Temperature?

Onions should be kept between 45 and 55ᵒF in a cool, dark environment. When stored in a cool, dry place, whole raw onions will last two to three months. A cellar, pantry, unheated basement, or garage are examples of places that provide these conditions. However, finding a cool space like this in our homes might be difficult for many of us. If this is the case, you can store onions in the refrigerator to extend their shelf life. If you don’t have enough fridge space and have to store onions at room temperature, the entire, raw onions will survive up to a week at room temperature.

If you’re storing onions at room temperature or below, make sure they’re well ventilated to avoid mold. An open basket, mesh bag, or a paper bag with a loose cover will suffice. If you store onions in a plastic bag, they will not be able to breathe.

How Long Do Onions Last In The Fridge?

Whole onions can be kept in the fridge for 1-2 months, but this isn’t the most efficient use of fridge space. Also, they can readily absorb moisture in the refrigerator and go bad quickly. Cut onions have a shorter shelf life and can only be kept in the fridge for about a week before losing their freshness. Cut onions should be stored in an airtight container and opened as few times as possible for best effects.

Can You Freeze Onions?

Frozen onions can be stored for up to eight months, but expect them to lose their crispness and flavor if you do so for too long. It’s ideal to keep onions frozen for no more than one month, especially if you want them to retain some crunch when thawed.

How To Freeze Onions?

  1. Peel and slice or chop. Whole onions should not be frozen since they cannot tolerate extremely cold temperatures and will defrost into a gooey mess. To keep the onions from getting too mushy when thawed, chop them into thick slices.
  2. Freeze the onions in little chunks that can be used all at once in freezer bags. Onions aren’t very good at refreezing.
  3. To keep the onions as dry as possible, squeeze out as much air as possible.
  4. Place the container in the freezer until ready to use.

How Long Does It Take To Freeze Onions?

In the freezer, onions require at least 2 hours to freeze. If the onions aren’t firm enough, freeze them for 4 to 5 hours.

How Long Do Onions Last In The Freezer?

There’s good news! Raw onions can be frozen to extend their shelf life. Begin by peeling the onions, then chopping or slicing them to your preference. Wrap them tightly in aluminum foil or plastic wrap and store them in an airtight container or freezer bag. In the freezer, raw onions can last up to eight months. When stored in an airtight container or freezer bag, cooked onions can be frozen for up to 12 months.

How Long Do Onions Last In Cold Storage?

Onions are prepared for cold storage by gradually lowering the temperature by 0.5°C per day to attain the appropriate cold storage temperature. In cold storage, onions are kept at temperatures ranging from 0 to 2°C, depending on the type. Onions can be kept in the refrigerator for up to 10 months without deteriorating. In order to keep onions fresh, they need to be ventilated. Onions are not transported directly from cold storage to the market after being stored, but are heated in temperature-controlled conditions to avoid condensation.

Best Way To Store Onions

To maintain peak freshness, onions, like most fresh vegetables, must be stored in the proper conditions. To get the most out of your onions, follow these guidelines on how to keep them properly:

  • Protect Them From Moisture: Moisture provides the ideal environment for germs and mold to thrive
  •  Ensure That The Temperature Is Correct: The best temperature for storing them is between 40 and 50°F. If it’s too hot, the onions will sprout and dry; if it’s too cold, they will lose their hardness, color, and become moldy.
  • Keep it separate from other foods: Store onions separately from potatoes, tomatoes, apples, melons, and bananas, in particular. Ethylene from these foods causes onions to ripen, making them mushy.
  • Store in the refrigerator: Cut your onions into little pieces with a slicer or a food processor. Then, in little amounts that may be used all at once, store the chopped onions in freezer bags. Flatten each freezer bag to eliminate air bubbles and make stacking them in the freezer easier.
  • Use Appropriate Packaging
