How Long Does Russet potato Last?

Storage times and freshness tips for russet potato in different conditions.

Safety first: This guide provides general information. When in doubt, throw it out! Trust your senses and err on the side of caution. If something smells, looks, or tastes off, don't consume it.

uncooked in cool, dark pantry
2-4 weeks (up to 1-2 months under ideal root cellar conditions)

Signs of Spoilage

Soft spots or mushy texture, extensive greening of the skin, significant sprouting (more than small eyes), wrinkled or shriveled skin, visible mold (fuzzy white, black, or green patches), an earthy, musty, or unpleasant odor.

How to Check

Visually inspect for green areas, large sprouts, mold, or shriveling. Gently squeeze the potato; it should feel firm. Softness or mushiness is a sign of spoilage. Smell the potato; a fresh potato has a mild, earthy scent. Any strong, sour, or musty odor indicates it's past its prime.

Storage Tips

Store in a cool (45-55°F / 7-13°C), dark, and well-ventilated place. Avoid storing in the refrigerator, as cold temperatures convert starch to sugar, affecting flavor and texture. Keep away from onions and apples, as gases they emit can accelerate sprouting. Do not wash potatoes until just before use, as moisture can encourage mold growth.

raw, cut in fridge
1-2 days

Signs of Spoilage

Significant browning or graying (oxidation), slimy texture, sour or fermented smell.

How to Check

Visually check for extensive discoloration (beyond slight browning from initial air exposure) and a slimy film. Smell for any sour or unpleasant odors. Touch to check for sliminess.

Storage Tips

To prevent browning and extend freshness slightly, submerge cut potatoes in cold water in an airtight container in the refrigerator. Change the water daily if storing for longer than a few hours. This is a short-term solution for prepped potatoes.

cooked in fridge
3-5 days

Signs of Spoilage

Slimy or sticky texture, sour or off-putting smell, visible mold growth (white, green, black fuzzy spots), unusual discoloration (dark spots, graying).

How to Check

Visually inspect for mold or discoloration. Smell for any sour, fermented, or generally unpleasant odors. Touch the potato; if it feels slimy or sticky, it's spoiled.

Storage Tips

Store cooked potatoes in an airtight container to prevent drying out and absorption of other food odors. Ensure potatoes are cooled completely before refrigerating to prevent bacterial growth and condensation.

cooked in freezer
10-12 months (quality best within 6 months)

Signs of Spoilage

Severe freezer burn (dry, discolored, leathery patches), significant deterioration in texture upon thawing (excessively mushy or watery, though some texture change is normal), off-flavors (rare if properly stored).

How to Check

Visually inspect for extensive freezer burn. After thawing, assess texture; if it's unpleasantly mushy or watery, quality has degraded significantly. A smell test might reveal off-odors, though this is less common for properly frozen potatoes.

Storage Tips

Raw potatoes do not freeze well; they become mushy upon thawing. Always cook or blanch potatoes before freezing. Mash, roast, or par-cook diced potatoes before freezing for best results. Store in airtight, freezer-safe containers or heavy-duty freezer bags to prevent freezer burn.
