Pantry storage
How long do potatoes last in the pantry?
About 30 days for potatoes in a cool, dark pantry. USDA gives whole potatoes 1 to 2 months; Well Stockd plans on the short end. FoodKeeper doesn’t split potatoes by kind, so the same times are a fair guide for russet, Yukon Gold, red, yellow, fingerling and baby potatoes.
Times are for a cool, dark, ventilated spot. They’re a guide, not a safety guarantee.
How we checked this: the storage times here come from USDA FoodKeeper and USDA FSIS, plus any other source named on the page, and each one is checked against its source before the page goes live. Editorial policy

How long they keep
- Whole, uncut potatoes
- 1 to 2 months in a cool dark place; refrigeration is not recommended Source: USDA FoodKeeper: Potatoes (opens in a new tab)
- Peeled or cut potatoes
- About 24 hours in the fridge, in a covered bowl of cold water. Source: Idaho Potato Commission: storing peeled potatoes (opens in a new tab)
- Freezer
- 10 to 12 months for cooked or mashed potatoes at best quality. Frozen food stays safe indefinitely at 0°F; the time is about texture and flavor. Source: USDA FoodKeeper: Potatoes (opens in a new tab)Compare freezer times for other foods on the printable freezer storage chart.
- How to store them
- Dark, ventilated, away from onions. Do not refrigerate whole, raw potatoes: cold converts starch to sugar and darkens them on cooking. Green patches are solanine; cut them away generously or discard.
How to tell if potatoes have gone bad
Dates are estimates; these are the checks that actually decide it. Don’t taste food to check whether it has gone bad.
Throw them out at once if you see:
- Green under the skin, or green over a large area
Where the first sign comes from: Health Canada: glycoalkaloids in foods (opens in a new tab), Iowa State University Extension: sprouting or greening potatoes (opens in a new tab), Michigan State University Extension: food safety of potatoes (opens in a new tab)
Warning signs (throw them out if you notice more than one):
- Green skin
- Sprouting eyes
- Soft or weeping flesh
- Musty smell
Sources and limits
Even a longer time like this depends on the packaging, the temperature, how ripe the food is and whether it’s been opened.
Well Stockd doesn’t know when this food was harvested, packed or bought. Write down the date you bought or stored it, follow the package directions, keep it somewhere cool and dark, and check the official listing when food safety is in question.
USDA FoodKeeper gives whole potatoes 1 to 2 months in the pantry, and Well Stockd plans on the low end.
The times in the table come from USDA FoodKeeper, USDA FSIS guidance on pantry storage, and any source named beside a row. The number at the top is Well Stockd’s own estimate. It’s a guide, not a safety guarantee: FoodKeeper says storage times are guidelines, and quality varies with how food is grown, handled, shipped and stored. This page was last updated .
