# Step-by-Step Directions:
01 - Preheat oven to 375°F. Grease a 9x13-inch baking dish.
02 - Boil salted water and cook spaghetti until just al dente. Drain and set aside.
03 - Melt 4 tablespoons of butter in a large skillet over medium heat. Add chopped onions and sauté for 2 minutes. Add sliced mushrooms and cook until softened and lightly browned, about 5 minutes. Stir in minced garlic and cook for an additional minute.
04 - Sprinkle flour over the vegetables and cook, stirring continuously, for 2 minutes.
05 - Gradually whisk in white wine, scraping up any browned bits from the pan, and simmer for 2 minutes.
06 - Add broth, whole milk, and heavy cream while whisking to maintain smoothness. Bring to a simmer and cook until sauce slightly thickens, approximately 3 to 4 minutes.
07 - Stir in dried thyme, freshly grated nutmeg, kosher salt, and black pepper. Remove from heat.
08 - Fold cooked turkey, optional peas, and drained pasta into the sauce. Mix in grated Parmesan and shredded mozzarella or Gruyère cheese evenly.
09 - Transfer the mixture into the prepared baking dish.
10 - In a small bowl, mix panko breadcrumbs, melted butter, and grated Parmesan. Sprinkle evenly over the casserole. Bake for 25 to 30 minutes until bubbly with a golden crust.
11 - Allow casserole to rest for 10 minutes before serving to set flavors.
