Sweet potatoes are sturdy root vegetables that thrive when kept in a cool, dark, and dry environment. When stored properly in a well-ventilated spot like a pantry, they typically maintain peak quality for 3 to 5 weeks. It is important to avoid refrigeration for raw sweet potatoes, as cold temperatures can alter their texture and flavor. For the best results, keep them away from moisture and other ethylene-producing fruits. This guide helps you identify the stages of freshness, from the ideal firm state to the clear signs of spoilage like mold or deep soft spots. Understanding these cues ensures you use your produce while it is nutritious and flavorful.

Heads up: shelf-life ranges are estimates based on home storage. We make no guarantee of accuracy. When unsure, throw it out.
