10 - 1/2 cup heavy cream
11 - 1 cup grated Parmesan cheese
12 - 1 cup shredded mozzarella or Gruyère cheese

18 - 1/4 teaspoon black pepper
→ Topping
19 - 1/2 cup panko breadcrumbs
20 - 2 tablespoons unsalted butter, melted
21 - 2 tablespoons grated Parmesan cheese
# Directions:
01 - Preheat the oven to 375°F. Grease a 9x13-inch baking dish thoroughly.
02 - Boil salted water and cook spaghetti until just al dente. Drain and set aside.
03 - Melt 4 tablespoons butter in a large skillet over medium heat. Add chopped onions and sauté for 2 minutes. Incorporate mushrooms and cook until softened and slightly browned, about 5 minutes. Stir in minced garlic and cook for 1 more minute.
04 - Sprinkle flour over the sautéed vegetables and cook while stirring for 2 minutes to eliminate raw taste.
05 - Gradually whisk in the white wine, scraping the skillet to release browned bits, then simmer for 2 minutes.
06 - Whisk in chicken broth, whole milk, and heavy cream until smooth. Simmer the sauce until it thickens slightly, approximately 3 to 4 minutes.
07 - Add dried thyme, freshly grated nutmeg, kosher salt, and black pepper to the sauce. Remove from heat.
08 - Stir the cooked turkey, peas if using, and drained pasta into the sauce. Fold in grated Parmesan and shredded mozzarella or Gruyère cheese until evenly combined.
09 - Transfer the mixture into the prepared baking dish, spreading evenly.
10 - Mix panko breadcrumbs with melted butter and grated Parmesan. Sprinkle the topping uniformly over the casserole.
11 - Bake uncovered for 25 to 30 minutes until the top is bubbling and golden brown. Allow to rest for 10 minutes before serving.
