Store onions in a cool, dry, and dark place. Avoid places with moisture or sunlight. Use mesh bags or baskets to allow air flow. Do not store onions near potatoes. Potatoes release moisture that makes onions spoil faster.
Once cut, wrap onions tightly in plastic wrap or store in airtight containers. Keep cut onions in the refrigerator to slow down spoilage. Use them quickly, as cut onions lose freshness fast.
