Tips

  • How long do cooked sweet potatoes last in the fridge or freezer? The exact answer to that question depends to a large extent on storage conditions - refrigerate sweet potatoes (including mashed and baked sweet potatoes) within two hours of cooking.
  • To maximize the shelf life of cooked sweet potatoes for safety and quality, refrigerate the sweet potatoes in shallow airtight containers or resealable plastic bags.
  • Properly stored, cooked sweet potatoes will last for 3 to 5 days in the refrigerator.
  • How long can cooked sweet potatoes be left at room temperature? Bacteria grow rapidly at temperatures between 40 °F and 140 °F; cooked sweet potatoes should be discarded if left out for more than 2 hours at room temperature.
  • To further extend the shelf life of cooked sweet potatoes, freeze them.
  • To freeze whole baked sweet potatoes: Wrap potatoes individually in foil and then place together in heavy-duty freezer bags or airtight containers.
  • To freeze boiled and sliced or mashed sweet potatoes: sprinkle first with a small amount of lemon juice to prevent discoloration and then place in covered airtight containers or heavy-duty freezer bags.
  • How long do cooked sweet potatoes last in the freezer? Properly stored, they will maintain best quality for 10 to 12 months, but will remain safe beyond that time.
  • The freezer time shown is for best quality only - cooked sweet potatoes that have been kept constantly frozen at 0°F will keep safe indefinitely.
  • How long do cooked sweet potatoes last after being frozen and thawed? Cooked sweet potatoes that have been thawed in the fridge can be kept for an additional 3 to 4 days in the refrigerator before cooking; sweet potatoes that were thawed in the microwave or in cold water should be eaten immediately.
  • How to tell if cooked sweet potatoes are bad? The best way is to smell and look at the sweet potatoes: discard any that have an off smell or appearance, do not taste first.
