Serving

Instructions
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
