Use your leftover turkey to make this creamy, comforting pasta bake. This casserole combines shredded turkey, mushrooms, and spaghetti in a rich sauce, topped with cheese and baked until bubbly.

Ingredients

Scale
  • 2 cups cooked, shredded turkey
  • 8 ounces spaghetti or egg noodles
  • 1 tablespoon butter
  • 1/2 cup chopped onion
  • 8 ounces sliced fresh mushrooms
  • 1 can (10.5 ounces) condensed cream of mushroom soup
  • 1/2 cup chicken broth
  • 1/2 cup milk
  • 1/2 cup shredded Parmesan cheese, plus extra for topping
  • 1/4 cup dry sherry or white wine (optional)
  • 1 cup frozen peas, thawed
  • 1/2 cup breadcrumbs

Instructions

  1. Preheat your oven to 375 degrees F. Lightly grease a 2-quart baking dish.
  2. Cook the spaghetti or egg noodles according to package directions until al dente. Drain well.
  3. While the pasta cooks, melt the butter in a large skillet over medium heat. Add the onion and mushrooms. Cook until the vegetables soften, about 5 to 7 minutes.
  4. Stir in the condensed cream of mushroom soup, chicken broth, and milk into the skillet. Cook, stirring constantly, until the mixture is smooth and heated through.
  5. Remove the skillet from the heat. Stir in the 1/2 cup of Parmesan cheese, sherry (if using), shredded turkey, and thawed peas. Mix until everything is coated.
  6. Fold the cooked pasta into the sauce mixture. Pour the entire mixture into the prepared baking dish.
  7. In a small bowl, mix the extra Parmesan cheese with the breadcrumbs. Sprinkle this topping evenly over the casserole.
  8. Bake for 20 to 25 minutes, or until the casserole is hot and the topping is golden brown. Let it rest for 5 minutes before serving.

Notes

  • For a richer flavor, substitute the chicken broth with turkey broth made from your holiday drippings.
  • If you do not have breadcrumbs, crush plain crackers to create a topping.
  • This recipe works well with leftover chicken if you do not have turkey.
