→ Dairy
07 - 4 tbsp unsalted butter
08 - 1/4 cup all-purpose flour
09 - 2 cups whole milk
10 - 1/2 cup heavy cream
11 - 1 cup grated Parmesan cheese
12 - 1 cup shredded mozzarella or Gruyère cheese
→ Liquids
13 - 1/2 cup dry Chardonnay or other dry white wine
14 - 1 cup low-sodium chicken or turkey broth
→ Seasonings
15 - 1/2 tsp dried thyme
16 - 1/4 tsp freshly grated nutmeg
17 - 1/2 tsp kosher salt, plus more to taste
18 - 1/4 tsp black pepper
→ Topping
19 - 1/2 cup panko breadcrumbs
20 - 2 tbsp unsalted butter, melted
21 - 2 tbsp 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 - In a large skillet over medium heat, melt 4 tablespoons unsalted butter. Add finely 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 1 additional minute.
04 - Sprinkle 1/4 cup all-purpose flour over the vegetables and cook, stirring continuously, for 2 minutes to remove the raw flour taste.
05 - Gradually whisk in 1/2 cup dry white wine, scraping the skillet to loosen browned bits. Simmer for 2 minutes. Add 1 cup low-sodium broth, 2 cups whole milk, and 1/2 cup heavy cream, whisking until smooth. Bring to a gentle simmer and cook until the sauce thickens slightly, approximately 3 to 4 minutes.
06 - Stir in 1/2 teaspoon dried thyme, 1/4 teaspoon freshly grated nutmeg, 1/2 teaspoon kosher salt, and 1/4 teaspoon black pepper. Remove from heat.
07 - Add the cooked turkey, frozen peas if using, and the drained pasta into the sauce. Toss well to combine. Fold in 1 cup grated Parmesan and 1 cup shredded mozzarella or Gruyère cheese until evenly incorporated.
08 - Transfer the mixture into the prepared baking dish and spread evenly.
09 - In a small bowl, mix 1/2 cup panko breadcrumbs with 2 tablespoons melted unsalted butter and 2 tablespoons grated Parmesan cheese. Sprinkle the mixture uniformly over the casserole.
10 - Bake uncovered for 25 to 30 minutes, until bubbly and the topping turns golden brown. Let rest for 10 minutes before serving.
