You can easily store leftover goujons in the fridge for up to three days. Once cooled, put any leftover cooked chicken goujons in an airtight container. Then, store them until you’re ready to eat the chicken tenders. You can also freeze these chicken strips (before or after you cook them). Lay them out flat on a baking sheet in the freezer. Once the strips are frozen, transfer them into an airtight container. Make sure to use frozen chicken fingers within six weeks.
