Turkey: Cooked turkey can be kept in a fridge for three or four days. The USDA does not provide guidelines on freezing turkey leftovers. The same is true if your family likes to partake in other meat-based protein sources on Thanksgiving day, including cooked chicken, cooked pork and cooked beef. Plant-based alternatives like tofu can be stored for up to one week in a fridge if fresh or five months in a freezer, according to the USDA’S FoodKeeper App.
Stuffing: The USDA said leftover stuffing should be consumed or frozen within three or four days. When frozen, stuffing can last between two and three months. Uncooked stuffing can also be frozen but it will need to be cooked immediately when removed from a freezer, according to the USDA’s "Handling Stuffing with Care Guide." The frozen stuffing should be cooked until it reaches 165 degrees Fahrenheit.
Potatoes, Yams and Green Beans: Mashed potatoes and other Thanksgiving vegetables like yams and green beans can last three or four days when stored in a fridge.
Cranberry Sauce: Thanksgiving cranberry sauce can be homemade or come from a can, but both options have a drastically different shelf life. According to the USDA’s FoodKeeper App, homemade cranberry sauce can be refrigerated seven to 10 days after purchase while canned cranberry sauce can be refrigerated for one to two weeks after opening. Freezing is not recommended because thawing cranberry sauce may make it "become too watery."
Gravy: Leftover gravy can be stored in a fridge for three to four days or in a freezer for four to six months, according to the USDA. When reheating gravy, the USDA recommends boiling the liquid to ensure its safety. The same is true for leftover sauces and soups.
Pie: The USDA said homemade pies that contain egg, cream or chiffon can be stored in a fridge for three to four days, including pumpkin, pecan, lemon meringue and custard pies. Fruit-based pies, on the other hand, can be stored at room temperature for one to two days or in a fridge for up to a week. Store-bought or bakery pies may contain preservatives, so the USDA recommends consulting the pie's packaging or baker in these instances.
While the USDA does not have freezing guidelines for baked pies, the Michigan State University Extension school reports that baked pies can be frozen for up to six months.
