Onion, Golden SpainShelf Life, Storage, and Spoilage Guide
Pantry
1-3 months
Store whole, unpeeled onions in a cool, dry, dark, and well-ventilated place. Avoid storing with potatoes, as both release gases that can accelerate spoilage.
Refrigerator
7-10 days
Whole, unpeeled onions are best stored in a cool, dry, dark place. If you must refrigerate whole onions, they may become soft and lose some flavor. Once cut, store in a sealed container in the refrigerator.
Freezer
3-6 months
Onions should be chopped and blanched before freezing for best quality. Freezing whole raw onions is not recommended as it significantly degrades texture.
Signs of Spoilage
- Soft spots or mushy texture
- Mold growth
- Strong, unpleasant odor
- Discoloration (dark spots)
- Excessive sprouting (while edible, indicates quality decline)
Room Temperature Safety
40°F–140°F (4°C–60°C)
Cut or cooked onions should not be left at room temperature (between 40°F and 140°F) for more than 2 hours. If the ambient temperature is above 90°F (32°C), they should not be left out for more than 1 hour.
Safe Handling
Wash hands thoroughly with soap and water before and after handling onions.
Wash whole onions under running water before peeling or cutting.
Prevent cross-contamination by keeping raw onions separate from ready-to-eat foods and using separate cutting boards and utensils.
Refrigerate cut, peeled, or cooked onions promptly within 2 hours (1 hour if the ambient temperature is above 90°F/32°C).
