how long do sweet potatoes last

Whole, raw sweet potatoes usually last 1–2 weeks at room temperature and up to about a month in a cool, dark, well‑ventilated place like a pantry or cellar.

Quick Scoop

  • Whole, raw (room temp, on the counter): roughly 1–2 weeks, sometimes up to 3–4 weeks if your kitchen is cool and dry.
  • Whole, raw (ideal cool storage 55–60°F / 12–16°C, dark, ventilated): about 1–3 months, with some sources noting several months in root‑cellar‑like conditions.
  • Cut, raw: about 2–5 days in the fridge if kept airtight; 2–3 days if stored in water that you change daily.
  • Cooked: about 3–5 days in the fridge in a shallow, airtight container.
  • Frozen cooked: best quality for 6–12 months when well wrapped and kept at 0°F.

Quick spoilage check

Toss your sweet potatoes if they are very soft or mushy, heavily shriveled, show significant mold, or have large dark, rotten areas; a small bad spot can be cut away if the rest looks and smells normal.
