Ingredients
 

Main Ingredients

  • 4.5 cup leftover stuffing, loosely packed
  • 3 cup cooked turkey, chopped
  • 2.25 cup turkey gravy
  • 2 cup mixed vegetables, thawed corn, peas, and carrots work well
  • 3.5 cup mashed potatoes use leftover potatoes
  • 1.5 cup shredded cheddar cheese
  • 0.5 cup milk any kind
  • 2 tbsp unsalted butter, melted
  • 0.25 cup sliced green onions optional garnish
  • 1 tsp garlic powder
  • 0.5 tsp dried thyme
  • 0.5 tsp kosher salt adjust to taste
  • 0.5 tsp black pepper

Instructions

Preparation Steps

  • Heat oven to 375°F. Grease a 9x13-inch baking dish.
  • Warm gravy with milk in a saucepan over medium heat until smooth and steamy.
  • Stir in turkey, mixed vegetables, garlic powder, thyme, and black pepper. Simmer 2 minutes.
  • Spread stuffing in the prepared dish. Drizzle with half the melted butter and press gently into an even layer.
  • Pour the turkey-vegetable gravy mixture evenly over the stuffing.
  • Dollop mashed potatoes over the top, then spread to cover. Brush with remaining butter and sprinkle with salt.
  • Top with cheddar and green onions.
  • Bake 30–35 minutes until bubbling and golden at the edges. Rest 10 minutes before serving.

Notes

Try a sweet-savory twist by dotting the potato layer with a few teaspoons of cranberry sauce. For a crispier top, broil the last 2 minutes. Leftovers keep 3–4 days chilled; reheat covered at 350°F until hot.
