Step 1: Preheat and Prep
Preheat your oven to 375°F (190°C). Lightly grease a 9x13-inch baking dish.
Step 2: Cook the Pasta
Cook the spaghetti according to the package instructions until al dente. Drain and set aside.
Step 3: Cook the Chicken
In a large skillet, heat the olive oil over medium-high heat. Season the chicken with salt and pepper, then add it to the skillet. Cook until golden brown and cooked through, about 5-7 minutes. Remove the chicken from the skillet and set aside.
Step 4: Sauté the Mushrooms and Garlic
In the same skillet, add the mushrooms and cook until softened, about 5 minutes. Add the minced garlic and cook for another minute.
Step 5: Make the Sauce
Sprinkle the flour over the mushrooms and stir to combine. Gradually whisk in the chicken broth and heavy cream, stirring constantly to avoid lumps. Bring the mixture to a simmer and cook until thickened, about 3-5 minutes. Stir in the Parmesan cheese until melted.
Step 6: Combine Everything
In a large mixing bowl, combine the cooked pasta, chicken, mushroom sauce, and frozen peas (if using). Toss until everything is well coated.
Step 7: Assemble and Bake
Transfer the mixture to the prepared baking dish. Sprinkle the shredded mozzarella cheese over the top. Bake for 20-25 minutes, or until the cheese is melted and bubbly.
Step 8: Garnish and Serve
Remove from the oven and let cool for 5 minutes. Garnish with chopped parsley and serve warm.
