Shelf Life Tips

• How long do onions last? The precise answer to that question depends to a large extent on storage conditions - after purchasing, keep whole raw onions in a dry, dark area.
• Whole raw onions will last for 2 to 3 months in a cool (45-55° F; warmer than the refrigerator, but colder than normal room temperature) dark area.
• If a cool, dark area is not available, then onions should be refrigerated to ensure maximum shelf life.
• Properly stored, whole raw onions will last for 2 to 3 months in the refrigerator.
• To extend the shelf life of onions, store onions in a loosely covered paper or mesh bag or basket to allow for air circulation; do not store onions in plastic bags, as the lack of air movement will reduce their shelf life.
• To further extend the shelf life of onions, do not store onions near potatoes, as the chemical reaction will speed the spoilage of both.
• How long do raw onions last after they've been sliced or chopped? Chopped raw onions will last 7 to 10 days in the refrigerator; store in covered airtight containers.
• How long do onions last in the fridge once they have been cooked? Cooked onions will usually stay good for 3 to 5 days in the refrigerator and 10 to 12 months in the freezer.
• Can you freeze raw onions? Yes, to freeze: (1) Peel, then slice or chop onions; (2) Place in airtight containers or heavy-duty freezer bags, or wrap tightly in heavy-duty aluminum foil or plastic wrap.
• How long do raw onions last in the freezer? Properly stored, they will maintain best quality for about 6 to 8 months, but will remain safe beyond that time.
• The freezer time shown is for best quality only - onions that have been kept constantly frozen at 0°F will keep safe indefinitely.
• How to tell if onions are bad or spoiled? Onions that are spoiling will typically become soft and discolored, and will often develop dark patches; discard any onions that have an off smell or appearance.
