The Impossible Burger should be handled as you would any other raw protein-- keep food safety in mind, and keep it cold!
If you choose to keep it frozen, we recommend thawing it for 24 hours in the fridge before using it. It will stay fresh for 10 days thawed and sealed in the fridge or 3 days once the package has been opened. If you don’t think you’ll be able to use the full package in one go, you may choose to thaw and portion what you need, then re-freeze the rest.
However you choose to store it, just be sure you use the entire package before the “best by” date. We can’t wait to see what you cook up!
