You can store Impossible Burger just like any other meat -- it poses no unique food safety risks.
Our products are sold both thawed and frozen; offerings will vary by store.
If sold thawed, the package should have a sticker with a “best by" date (added by the store). For best quality and freshness, we recommend keeping it in your refrigerator and finishing it off before that date. Like any other perishable food, though, after you’ve opened the package, the freshness starts to diminish. After the package has been opened, we recommend finishing it within three days, or by the “best by” date on the sticker -- whichever comes first.
You can re-freeze Impossible Burger to use later if needed. To make sure it stays fresh, we recommend it spend no more than three days total thawed once the package has been opened, and that you finish it off before the "use by" date printed on the back of the packaging.
If you purchase a frozen brick of Impossible Burger, you may choose to thaw it in the refrigerator prior to cooking. Once thawed, it will stay fresh with the package sealed for 10 days, or for three days once the package has been opened -- whichever comes first. The package should be consumed prior to the "use by" date printed on the back of the package.
If you purchase a frozen package of Impossible Burger patties, you can cook the patties from frozen or after thawing -- they're great either way! To thaw, remove as many patties as needed and cook them once they're thawed. Any remaining patties should be stored frozen in the sealed pouch, and the whole package should be consumed prior to the "use by" date printed on the back of the package.
