Yes, you can freeze leftover turkey. In fact, freezing turkey is a great way to reduce food waste and stretch your grocery budget. Leftover turkey can be stored in the freezer indefinitely, though it begins to lose flavor and moisture after three or four months. Before freezing, eliminate as much air as possible from the container or freezer bag to help preserve moisture and flavor. Separate turkey meat from the bones before freezing, but don't throw away the bones. Save them to make a savory stock! For convenience, freeze small portions of cooked leftover turkey in individual freezer bags for easy meal prep.
