Ingredients

Scale

Filling Ingredients

  • 2 cups shredded leftover turkey
  • 1 cup frozen mixed vegetables
  • 1 medium onion, chopped
  • 2 cloves garlic, minced
  • 1 cup heavy cream
  • 1 cup low-sodium chicken broth
  • 3 tbsp flour
  • 2 tbsp olive oil
  • 1 tsp dried thyme
  • 1 tsp dried sage
  • Salt and pepper to taste

Topping

  • 1 sheet puff pastry, thawed
  • 1 egg (optional, for egg wash)

Instructions

  1. Preheat Oven and Prepare Dish: Preheat your oven to 375°F (190°C) and grease a large casserole dish to prevent sticking and easy cleanup.
  2. Sauté Aromatics: In a skillet over medium heat, warm the olive oil. Add the chopped onion and minced garlic, sautéing them for about 3-4 minutes until they are soft and fragrant, forming the flavor base for the filling.
  3. Cook Vegetables: Add the frozen mixed vegetables to the skillet and cook until they are heated through, stirring occasionally to blend flavors nicely.
  4. Make Roux: Sprinkle the flour evenly over the vegetable mixture, stirring constantly to prevent lumps. Cook for 2-3 minutes to form a roux, which will thicken the sauce later.
  5. Add Liquids and Season: Gradually whisk in the heavy cream and chicken broth to the roux, stirring continuously. Bring the mixture to a simmer and let it thicken for about 5 minutes. Season with dried thyme, sage, salt, and pepper to enhance the flavor.
  6. Combine Turkey: Gently fold the shredded leftover turkey into the sauce until the turkey is well coated and evenly distributed throughout the mixture.
  7. Transfer to Casserole Dish: Pour the turkey and vegetable filling into the greased casserole dish and spread it out evenly.
  8. Add Puff Pastry Topping: Cover the filling with the thawed puff pastry sheet. Cut small slits in the pastry to allow steam to escape during baking. Optionally, brush the pastry with a beaten egg to achieve a shiny, golden crust.
  9. Bake: Place the casserole in the preheated oven and bake for 25-30 minutes, or until the puff pastry is puffed up and golden brown.

Notes

  • Use any combination of leftover turkey parts for the best flavor and texture.
  • Feel free to substitute frozen mixed vegetables with fresh ones of your choice.
  • For a lighter version, consider using half-and-half instead of heavy cream.
  • Make sure the puff pastry is fully thawed but still cold to prevent tearing when placing over the filling.
  • Let the casserole rest for 5-10 minutes after baking to set before serving.
