Stuffing cooked separately can be just as delicious. And it is safer because if you stuff the turkey there is a risk that the internal temperature of the stuffing will not reach a safe bacteria-killing temperature which is 165 degrees or higher. The unstuffed turkey will also cook faster reducing the risk of dried-out, overcooked meat. Leftover turkey, stuffing and gravy should be used within one month after freezing. Use freezer wrap or freezer containers.
Proper packaging is important to the success of frozen leftovers.
Do not leave air space. Squeeze excess air from freezer bags and fill rigid freezer containers to the top with dry foods.
