Can I make this ahead of time?

Yes. Assemble the casserole, cover tightly, and refrigerate for up to 24 hours. Add about 10 extra minutes to the baking time if it’s going in the oven straight from the fridge.

Ingredients

▢ 3 cups leftover stuffing or 6 ounces box Turkey-flavored stuffing mix, prepared
▢ 1 ½ cups leftover gravy or 12-ounce jar turkey gravy, divided
▢ 3 cups chopped or shredded leftover cooked turkey
▢ 14 ounces canned cranberry sauce, whole or jellied
▢ 3 cups leftover mashed potatoes or 24 ounces refrigerated container
▢ 1 ½ cups sharp cheddar cheese, shredded

Optional Garnish

▢ Fresh sage, chopped
▢ Salt and pepper, to taste

Instructions

Preheat Oven: Preheat oven to 375 °F and lightly coat 9×13-inch baking dish in nonstick cooking spray.
Layer Stuffing: Spread stuffing evenly across bottom of the prepared baking dish.
Add Gravy: Pour about ½ cup of gravy over stuffing to moisten it.
Add Cranberry Sauce: Spread cranberry sauce in an even layer on top of stuffing.
Add Turkey: Evenly scatter chopped or shredded turkey over cranberry layer.
Top with Mashed Potatoes: Spoon mashed potatoes over turkey and, using a rubber spatula, gently spread them into an even layer.
Add Remaining Gravy and Cheese: Drizzle remaining gravy over potatoes, then sprinkle shredded cheese evenly on top.
Bake Covered: Cover dish with aluminum foil and bake in preheated oven for 15 minutes.
Uncover and Finish Baking: Remove foil and bake for another 20 minutes, until cheese is melted and edges are lightly golden.
Cool and Serve: Allow casserole to cool for about 10-15 minutes so it can set a little. Taste and add salt and pepper if needed, then garnish with fresh chopped sage and serve.

Recipe Notes

Refrigerator Storage: Store in an airtight container and use within 3 days, as long as you’re still within 3-4 days of when the Thanksgiving food was first cooked.

Freezer Storage: After baking, cool it completely, then wrap tightly in foil or plastic wrap and freeze for up to 2 months. Thaw overnight in the refrigerator.

Reheating Instructions: Reheat individual portions in the microwave or cover the whole dish with foil and warm in a 350°F oven until the center is hot and steamy (165°F on a food thermometer). Add a little extra gravy if it looks dry.
