Most vegetables go in the fridge. Sweet potatoes are an exception. Raw ones do better in a cool pantry, and cold can harm them. Cooked ones are the opposite, and they need the fridge fast. Below: what Extension sources say, what to do if you already refrigerated them, and how to handle cut and cooked sweet potatoes.
Do sweet potatoes need to be refrigerated?
The Short Answer
Not raw. Extension sources say refrigerating whole sweet potatoes can cause a hard center and a bitter or unpleasant taste, so keep them in a cool, dark, dry spot instead. Cut or peeled pieces and cooked sweet potatoes do need the fridge: refrigerate within 2 hours, and use cooked ones within 3 to 4 days, per USDA. If you already refrigerated whole raw ones, cold mainly damages texture and flavor, so check for mold, rot or an off odor and cook them soon.

Key Takeaways

No, whole raw sweet potatoes shouldn’t go in the fridge. Utah State, NC State, Missouri, Oregon State and the NC SweetPotato Commission all link refrigeration to a hard center, and most add a bitter or unpleasant taste.
Penn State ties this to chilling injury below about 50 to 55°F, says not to refrigerate fresh roots, and lists a hard center after cooking as a symptom.
A cool, dark, dry, ventilated spot is the target. Penn State gives 55 to 60°F. Missouri Extension says room temperature is fine for up to a week.
Cooked sweet potatoes do need the fridge. USDA says to refrigerate within 2 hours and use within 3 to 4 days.
Cut or peeled raw pieces belong in the fridge too. FDA says to refrigerate peeled or cut veggies, and USDA says to do it within 2 hours. Neither gives a sweet-potato-specific shelf life.
Sweet potato pie made with eggs and milk should be treated like pumpkin and custard pies: refrigerate within 2 hours.
