Tips

  • How long do cooked potatoes last in the fridge or freezer? The exact answer to that question depends to a large extent on storage conditions - refrigerate all cooked potatoes (including baked, scalloped, roasted and mashed potatoes) within two hours of cooking.
  • To maximize the shelf life of cooked potatoes for safety and quality, refrigerate the potatoes in shallow airtight containers or resealable plastic bags.
  • Properly stored, cooked potatoes will last for 3 to 5 days in the refrigerator.
  • How long can cooked potatoes be left at room temperature? Bacteria grow rapidly at temperatures between 40 °F and 140 °F; cooked potatoes should be discarded if left out for more than 2 hours at room temperature.
  • Can you freeze whole baked potatoes or boiled potatoes? Whole cooked potatoes will be watery when thawed, and freezing is not recommended.
  • Can you freeze mashed, roasted or scalloped potatoes? Yes, these types of cooked potatoes freeze well; freeze in covered airtight containers or heavy-duty freezer bags.
  • How long do cooked 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 potatoes that have been kept constantly frozen at 0°F will keep safe indefinitely.
  • How long do cooked potatoes last after being frozen and thawed? Cooked potatoes (including mashed, roasted or scalloped potatoes) that have been thawed in the fridge can be kept for an additional 3 to 4 days in the refrigerator before cooking; potatoes that were thawed in the microwave or in cold water should be eaten immediately.
  • How to tell if cooked potatoes are bad? The best way is to smell and look at the potatoes: discard any that have an off smell or appearance, do not taste first.
