Sweet PotatoShelf Life, Storage, and Spoilage Guide
Pantry
3-5 weeks
Store raw sweet potatoes in a cool, dark, well-ventilated place (ideally 55-60°F or 13-16°C). Do not store in plastic bags as this can trap moisture and promote spoilage.
Refrigerator
Not RecommendedNot recommended for raw
Raw sweet potatoes should not be refrigerated as cold temperatures can cause a hard center, alter flavor, and speed up spoilage. Cooked sweet potatoes can be stored in an airtight container for 3-5 days.
Freezer
Not RecommendedNot recommended for raw
Raw sweet potatoes do not freeze well. For best quality, cook sweet potatoes (e.g., bake, boil, mash, or blanch cut pieces) before freezing. Store cooked sweet potatoes in airtight freezer-safe containers or bags for 10-12 months.
Signs of Spoilage
- Soft spots or mushy texture
- Mold growth (fuzzy spots, often white, green, or black)
- Unpleasant or sour odor
- Excessive sprouting with shriveled skin
- Discoloration beyond natural variations
Room Temperature Safety
The 'Danger Zone' for food is between 40°F (4°C) and 140°F (60°C), where bacteria can multiply rapidly.
Raw sweet potatoes can be stored at room temperature in a cool, dark place for several weeks. Once cooked, sweet potatoes should be promptly refrigerated or frozen to prevent bacterial growth.
Safe Handling
Wash sweet potatoes thoroughly under running water before peeling or cutting.
Avoid cross-contamination by using separate cutting boards and utensils for raw produce and raw meat/poultry.
Cook sweet potatoes to a safe internal temperature for consumption.
Promptly refrigerate or freeze cooked sweet potatoes within 2 hours.
