Storage chart
| Type | Pantry | Fridge | Freezer |
|---|---|---|---|
| yellow, white, red, etc. | 1 month | 2 months | 10–12 months |
| spring or green | 1 month | 1 week | 10–12 months |
Fridge at 40°F (4°C) or colder, freezer at 0°F (−18°C). Freezer times are for best quality; food kept frozen stays safe indefinitely.
Keep it longer
Keep most produce whole and unwashed until you use it; washing adds moisture that speeds spoilage. Store fruit that gives off ethylene (apples, bananas, avocados) away from leafy greens.
Common questions
How long do onions last in the fridge?
2 months in the refrigerator at 40°F (4°C) or below, according to USDA FoodKeeper data.
Can you freeze onions?
Yes. Frozen at 0°F (−18°C), onions keep best quality for 10–12 months. Frozen food stays safe indefinitely; the time is for taste and texture.
How long do onions last at room temperature?
1 month in a cool, dry pantry.
How can I tell if onions have gone bad?
Throw them out if you see mold, a slimy texture, an off smell or an odd color. For anything perishable, go by the storage time rather than smell: bacteria that cause food poisoning don't usually change how food looks or smells.
