A creamy baked spaghetti dish perfect for using leftover turkey, featuring mushrooms, a cheesy sauce, and a golden crumb topping.

Ingredients

Scale
  • 1 pound spaghetti or egg noodles
  • 2 tablespoons butter
  • 1 cup chopped mushrooms
  • 1/2 cup chopped onion
  • 1/4 cup all-purpose flour
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • 2 cups turkey broth
  • 1 1/2 cups milk
  • 1 cup shredded cheddar cheese
  • 1/2 cup grated Parmesan cheese
  • 3 cups shredded cooked turkey
  • 1 cup frozen peas
  • 1/2 cup bread crumbs
  • 2 tablespoons melted butter

Instructions

  1. Preheat your oven to 375°F (190°C). Cook spaghetti or egg noodles according to package directions. Drain and set aside.
  2. In a large skillet, melt 2 tablespoons of butter over medium heat. Add mushrooms and onion and cook until softened, about 5 minutes.
  3. Stir in the flour, salt, and pepper. Cook for 1 minute, stirring constantly.
  4. Gradually whisk in the turkey broth and milk until smooth. Bring to a simmer, stirring constantly, until the sauce thickens.
  5. Remove from heat. Stir in the cheddar cheese and Parmesan cheese until melted and smooth.
  6. Add the shredded turkey and peas to the sauce. Stir to combine.
  7. Add the cooked noodles to the sauce and toss gently to coat.
  8. Pour the mixture into a 9×13 inch baking dish.
  9. In a small bowl, combine the bread crumbs and 2 tablespoons of melted butter. Sprinkle evenly over the top of the casserole.
  10. Bake for 20-25 minutes, or until bubbly and the topping is golden brown.

Notes

  • For a richer sauce, you can use half-and-half instead of milk.
  • A splash of dry sherry or white wine can be added with the broth for extra depth of flavor.
  • If you don’t have leftover turkey, cooked chicken can be substituted.
  • This casserole is a great make-ahead meal; assemble it and refrigerate, then bake when ready, adding a few extra minutes to the baking time.
