Storage tips
- This is the recommended storage method for whole potatoes.
- The United States Potato Board notes refrigeration can cause potatoes to darken during cooking and to develop an unpleasantly sweet taste.
- Freezer timeline applies to cooked and mashed potatoes.
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 potatoes last in the fridge?
1–2 weeks in the refrigerator at 40°F (4°C) or below, according to USDA FoodKeeper data.
Can you freeze potatoes?
Yes. Frozen at 0°F (−18°C), potatoes keep best quality for 10–12 months. Frozen food stays safe indefinitely; the time is for taste and texture.
How long do potatoes last at room temperature?
1–2 months in a cool, dry pantry.
How can I tell if potatoes 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.
