Store in a cool, dark, well-ventilated place (55-60°F or 13-15°C). Do not store in plastic bags as this can trap moisture and promote spoilage.

Refrigerator

Not Recommended

Not recommended for raw; 3-5 days for cooked

Do not refrigerate raw sweet potatoes as it can cause a hard core, undesirable flavor, and accelerate spoilage. Store cooked sweet potatoes in a shallow airtight container.

Freezer

10-12 months (cooked)

Cooked sweet potatoes (mashed, pureed, or baked) can be frozen. Cool completely before freezing in airtight containers or heavy-duty freezer bags. Raw sweet potatoes do not freeze well.

Signs of Spoilage

  • Soft spots or mushy texture
  • Mold growth (white, green, or black fuzzy spots)
  • Strong, unpleasant odor
  • Excessive sprouting or shriveling

Room Temperature Safety

Cooked sweet potatoes should not be left out at room temperature for more than 2 hours (1 hour if the temperature is above 90°F/32°C). Raw, whole sweet potatoes are stored at cool room temperature (pantry conditions) and are not subject to the 2-hour rule.

40°F–140°F (4°C–60°C)

Promptly refrigerate cooked sweet potatoes to prevent bacterial growth. Raw sweet potatoes should be stored in a cool, dark, well-ventilated area, not directly on the counter in warm conditions.
