At room temperature, a healthy sweet potato lasts one to two weeks. In a cool, dark pantry (around 55°F), they can stretch to three or four weeks. If you cook them first, they’ll last in the fridge for about a week. But never leave them out after cooking—they’ll turn into bacterial nightclubs.
Here’s the weird trick: don’t wash them until you’re ready to use them. Moisture is the enemy. A wet sweet potato is a sad, moldy sweet potato. Treat them like a vampire—keep them dry and in the shadows.
