Shelf Life Tips

  • How long does frozen lasagna last? The precise answer to that question depends to a large extent on storage conditions - keep lasagna frozen at all times.
  • Properly stored, frozen lasagna will maintain best quality for about 18 months in the freezer, although it will usually remain safe to eat after that.
  • Is frozen lasagna safe to eat after the expiration date on the package? Yes, if properly stored - commercially frozen lasagna will typically carry a Best By," "Best if Used By," Best Before, or "Best When Used By" date but this is not a safety date, it is the manufacturer's estimate of how long the lasagna will remain at peak quality.
  • How long will frozen lasagna remain safe to eat? Frozen lasagna that has been kept constantly frozen at 0°F will keep safe indefinitely, as long as it has been stored properly and the package is not damaged.
  • How long can you safely leave frozen lasagna at room temperature? Frozen lasagna should be discarded if left for more than 2 hours at room temperature, as bacteria grow rapidly at temperatures between 40 °F and 140 °F.
  • How long does frozen lasagna last in the fridge after being cooked? Frozen lasagna that has been cooked can be kept for 3 to 5 days in the fridge; refrigerate the lasagna in airtight containers or wrap tightly in aluminum foil or plastic wrap.
  • How to tell if frozen lasagna is no longer good? If dry spots or discoloration have developed on the frozen lasagna, freezer burn has begun to set in - this will not make the lasagna unsafe to eat, but it will harm the texture and taste.
