How to Make Creamy Turkey Or Chicken Spaghetti Bake

  1. Preheat oven to 350°F (175°C). Butter a 3-quart casserole dish.
  2. In a large heavy saucepan, melt 2 tablespoons of butter over medium heat. Add 8 ounces of sliced fresh mushrooms and cook, stirring occasionally, until they release their liquid and begin to soften (about 5-7 minutes).
  3. Add 1 medium onion (chopped), 2 cloves garlic (minced), 2 stalks celery (finely chopped), and 1/4 teaspoon red pepper flakes. Sauté for 5-6 minutes until softened.
  4. Stir in 1/4 cup all-purpose flour and cook for 2-3 minutes, stirring constantly, until the flour is lightly toasted.
  5. Gradually whisk in 2 cups half-and-half, 1 tablespoon Dijon mustard, 1 cup chicken broth, and 1/4 cup dry white wine. Bring to a gentle boil, stirring constantly, then reduce heat and simmer for 20 minutes, stirring occasionally.
  6. Stir in 1/2 cup grated Parmesan cheese and simmer for 1 minute.
  7. While the sauce simmers, cook 1 pound spaghetti according to package directions until al dente. Drain very well.
  8. In a large bowl, combine the cooked spaghetti, 1 cup frozen peas, and 2 cups cooked, shredded turkey or chicken. Pour the sauce over the pasta mixture and toss gently to combine.
  9. Transfer the mixture to the prepared casserole dish.
  10. Sprinkle 1 cup shredded mozzarella cheese over the top.
  11. In a small bowl, combine 1/2 cup breadcrumbs, 1/4 cup grated Parmesan cheese, and 2 tablespoons melted butter. Sprinkle this mixture evenly over the mozzarella cheese.
  12. Bake for 30-35 minutes, or until the topping is golden brown and bubbly. Let stand for 10 minutes before serving.
