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