The Right (And Wrong) Way To Store Onions
Onions are a kitchen essential, but storing them improperly can make them sprout, soften, or spoil far sooner than they should. Knowing the right environment helps them stay firm and flavorful for weeks.
With a few simple habits, you can extend their shelf life and keep them ready for any recipe.
Should whole onions go in the fridge?
Refrigerators are too cold and humid for whole onions. The moisture can soften their outer layers and make them spoil faster. Cold temperatures also encourage them to absorb odors from nearby foods.
Unless the onion is already cut, the fridge will shorten its life rather than extend it. Room temperature storage is usually best.
The right way to store onions
Whole onions last longest in a cool, dry, and well ventilated space. A pantry, open basket, or mesh bag works well because air can circulate freely.
Keeping them away from direct sunlight and moisture helps maintain their firmness. Proper airflow prevents mold and slows sprouting, which keeps onions fresh for much longer.
Keep them away from potatoes
Storing onions next to potatoes causes both to spoil faster. Potatoes release moisture and gases that encourage onions to soften and sprout.
Keeping them in separate areas helps each last longer. A little distance goes a long way in reducing waste and keeping your pantry ingredients in good shape.
The best way to store cut onions
Once an onion is cut, the fridge becomes the right place. Wrap the pieces tightly or store them in an airtight container to keep odors contained and prevent them from drying out.
Cut onions stay fresh for a few days, but it is best to use them quickly for the strongest flavor. Always check for sliminess or strong odor before using.
The bottom line
Proper onion storage is simple but makes a noticeable difference. Whole onions need a dry, ventilated space, while cut onions belong in the fridge.
Keeping them away from potatoes and moisture helps them stay firm and flavorful. By making these simple adjustments to your storage habits, your onions will last longer and taste better in every dish.
