This beloved casserole combines tender chicken with pasta, mushrooms, and a rich, creamy sauce, topped with a crispy breadcrumb layer. It's a classic dish that's perfect for family dinners, potlucks, or any occasion where you want to serve something delicious and satisfying.

Ingredients:
2 cups cooked chicken, diced (use rotisserie chicken or leftover chicken for convenience)
8 oz spaghetti or linguine (uncooked)
1 cup sliced mushrooms (white or cremini)
1 small onion, finely chopped
3 cloves garlic, minced
1 cup frozen peas (optional)
1/4 cup butter
1/4 cup all-purpose flour
2 cups chicken broth
1 cup heavy cream
1 cup grated Parmesan cheese
1/2 teaspoon dried thyme
Salt and pepper to taste
1/2 cup shredded mozzarella cheese
1/2 cup breadcrumbs
2 tablespoons olive oil (for toasting breadcrumbs)
Instructions:
Prepare the Pasta:

Cook the spaghetti or linguine according to package instructions until al dente. Drain and set aside.
Cook the Vegetables:

In a large skillet, melt 1 tablespoon of butter over medium heat. Add the chopped onion and cook until softened, about 5 minutes. Add the sliced mushrooms and garlic, cooking until the mushrooms are tender and the garlic is fragrant. If using peas, stir them in during the last few minutes of cooking. Set the vegetable mixture aside.
Make the Sauce:

In the same skillet, melt the remaining butter. Stir in the flour and cook for 1-2 minutes, creating a roux. Gradually whisk in the chicken broth, ensuring no lumps form. Continue to cook until the sauce begins to thicken.

Stir in the heavy cream and Parmesan cheese, cooking until the cheese is melted and the sauce is smooth. Season with dried thyme, salt, and pepper.

Assemble the Casserole:

Preheat your oven to 375°F (190°C). In a large mixing bowl, combine the cooked pasta, chicken, and vegetable mixture. Pour the creamy sauce over the top and stir until everything is well coated.

Transfer the mixture to a greased 9x13-inch baking dish.
Add the Topping:

In a small bowl, mix the breadcrumbs with olive oil. Sprinkle the breadcrumb mixture evenly over the top of the casserole. Then, sprinkle the shredded mozzarella cheese on top of the breadcrumbs.
Bake:

Bake in the preheated oven for 25-30 minutes, or until the top is golden brown and the casserole is bubbly.
Serve:

Let the casserole cool for a few minutes before serving. Enjoy it as a hearty main dish or pair it with a side salad for a complete meal.
Tips for Success:

For Extra Flavor: Add a pinch of nutmeg to the sauce or a splash of white wine for a touch of sophistication.

Make Ahead: Prepare the casserole up to a day in advance and refrigerate before baking. Just add a few extra minutes to the baking time.
