Ingredients

Scale

Base Layer

  • 2 ½ cups mashed potatoes
  • 1 cup turkey gravy (divided from total)

Protein Layer

  • 2 cups shredded turkey
  • ½ cup turkey gravy (remaining)

Vegetable & Stuffing Layer

  • 2 cups stuffing
  • 1 cup green beans (drained)
  • ¼ cup chicken broth (optional, to moisten stuffing)

Topping

  • 4 tablespoons butter (divided into pats)

Serving

  • 1 cup cranberry sauce

Instructions

  1. Preheat and Prepare Dish: Preheat your oven to 350° F. Lightly grease a 9×13 or 9×9 baking dish to prevent sticking and set it aside.
  2. Prepare Mashed Potato Layer: In a medium mixing bowl, combine the mashed potatoes with 1 cup of the turkey gravy until smooth. Spread this mixture evenly across the bottom of the greased baking dish to form the base layer.
  3. Add Turkey and Gravy: Sprinkle the shredded turkey evenly over the mashed potato layer. Pour the remaining ½ cup of gravy over the turkey to keep the dish moist and flavorful.
  4. Layer Stuffing and Green Beans: Evenly spread the stuffing over the turkey layer, then add the drained green beans on top. If your stuffing feels dry, gently pour up to ¼ cup of chicken broth over the stuffing and beans to add moisture.
  5. Top with Butter and Bake: Place small pats of the butter evenly across the top of the casserole to melt during baking, adding richness. Bake in the preheated oven for 25-30 minutes, or until the casserole is heated through and bubbly.
  6. Serve with Cranberry Sauce: Remove from oven and serve hot with cranberry sauce on the side for a perfect balance of sweet and savory flavors. Enjoy your comforting Thanksgiving leftovers casserole!

Notes

  • Use leftover turkey gravy for authentic flavor, or substitute with a store-bought turkey or chicken gravy.
  • If stuffing is very dry, do not skip adding chicken broth to prevent dryness in the casserole.
  • Feel free to add other leftover vegetables for extra texture, such as roasted carrots or peas.
  • Use a 9×9 dish for a thicker casserole; a 9×13 dish will yield thinner layers and shorter baking time.
  • Leftovers can be refrigerated for up to 3 days and reheated in the oven until warmed through.
