10-12 months (best quality)



  • How long does frozen kale last? The precise answer to that question depends to a large extent on storage conditions - keep kale frozen at all times.
  • Properly stored, frozen kale will maintain best quality for about 12 months in the freezer, although it will usually remain safe to eat after that.
  • Is frozen kale safe to eat after the expiration date on the package? Yes, if properly stored - commercially frozen kale 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 frozen kale will remain at peak quality.
  • How long will frozen kale remain safe to eat? Frozen kale 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 kale at room temperature? Frozen kale should be discarded if left for more than 6 hours at room temperature, as bacteria grow rapidly at temperatures between 40 °F and 140 °F.
  • How to tell if frozen kale is no longer good? If dry spots or discoloration have developed on the frozen kale, freezer burn has begun to set in - this will not make the kale unsafe to eat, but it will harm the texture and taste.
