How Long Does Onion Last?

The shelf life of onions is determined by how they are kept, their age, and whether they are whole, chopped, or fried. Whole onions may be stored for up to 3 months if kept cold, dry, and dark, ideally in the pantry. When onions are stored for an extended period, even under ideal circumstances, they begin to dry out and shrivel.


You should be able to consume old onions, but you’ll probably have to eliminate many layers before you get to the fresher core. Whole onions may be stored in the fridge for around 1-2 months. Cut onions have an even shorter shelf life and will only last about a week in the fridge before their quality declines. For optimal results, keep sliced onions in an airtight container and restrict the number of times the container is opened.


Although freezing sliced onions may prolong their life by 5-8 months, they will become limp and soggy once thawed. Finally, if you saute your onions, they will last in the fridge for about 2-3 days before spoiling.

4 Ways to Tell If an Onion Is Bad

1. Discoloration

The appearance of black or brown patches on the outer peel of onion is the first indicator that it is going rotten. This occurs when whole onions are left over an extended period. Unless it is soft and stinky, it should last a few days before being discarded. We suggest peeling the onions, removing discolored patches in the inner layer, and using them as quickly as feasible.

2. Mold

Mold is a common indicator of rotting in any food, including onions. Onions that have been exposed to moisture will develop mold on the surface. However, before discarding moldy onions, look for other indicators of decomposition such as discoloration, an off-odor, and squishiness.


If it is just mold, you may prolong the shelf life of the onions by cleaning off the mold with a dry cloth and keeping them in the refrigerator until ready to use. It is preferable to utilize molding onions as soon as possible since they will accumulate moisture in the fridge and begin to deteriorate.

3. Smell

Onions, whether whole or sliced, have a distinct odor. When the onion begins to smell bad, it frequently has additional indicators of decomposition, such as discoloration, oozing, and feeling squishy to the touch. In this scenario, the onions must be removed.


Cut onions left out at room temperature for more than two hours may not display the usual indications of rotting, but they should be discarded if not refrigerated for that long. Cooked onions that have gone rotten will smell fishy and seem slimy. We do not advocate sampling cooked onions that are older than three days.

4. Sprouting And Drying

When onions are left in the pantry for too long, they may sprout, but there is nothing wrong with eating them. However, immediately after sprouting, the onion may turn spongy and eventually shrivel up, losing its freshness.

How To Store Vidalia Onions

Due to their high water content, Vidalia onions have a shorter shelf life than other onion cultivars. Keeping them cool and dry is the key to keeping them from going bad soon. One of the best locations to keep them is in the refrigerator’s vegetable bin, where they may stay for weeks.


To extend their shelf life, even more, we suggest wrapping each onion separately in a paper towel, which aids in moisture absorption. Then, with the vents closed, store them in the crisper drawer apart from other vegetables. Potatoes and onions should be kept separately since onions generate gasses that cause your potatoes to sprout, and potatoes release moisture that causes onions to become soft.
