Ingredients

• 2 pounds spaghetti
• 6 cups cooked chicken breast, shredded
• 1 cup butter
• 1 cup all-purpose flour
• 6 cups chicken broth
• 3 cups heavy cream
• 4 cups sliced white mushrooms
• 2 medium onion, finely chopped
• 4 cloves minced garlic
• 2 cups grated Parmesan cheese
• 4 cups shredded mozzarella cheese
• 2 teaspoons salt
• 1 teaspoon black pepper
• 2 tablespoons dried parsley (optional, for garnish)

Directions

Step 1

Preheat your oven to 350°F (175°C) and grease two large 9x13-inch baking dishes.

Step 2

Cook the spaghetti in a large pot of salted boiling water until al dente. Drain and set aside.

Step 3

In a large skillet, melt the butter over medium heat. Add the chopped onions and garlic, and sauté until softened, about 2-3 minutes.

Step 4

Add the sliced mushrooms to the skillet and cook until they release their liquid and are lightly browned, about 5-6 minutes.

Step 5

Sprinkle the flour over the mushroom mixture and stir well to combine. Cook for 1-2 minutes to remove the raw flour taste.

Step 6

Gradually whisk in the chicken broth and heavy cream, stirring constantly until the mixture thickens into a smooth, creamy sauce.

Step 7

Add the Parmesan cheese, salt, and black pepper to the sauce, stirring until the cheese is melted and incorporated.

Step 8

In a large mixing bowl, combine the cooked spaghetti, shredded chicken, and the creamy mushroom sauce. Toss well to coat everything evenly.

Step 9

Divide the mixture evenly between the two greased baking dishes. Sprinkle shredded mozzarella cheese on top of each dish.

Step 10

Bake in the preheated oven for 25-30 minutes, or until the cheese is melted and bubbly.

Step 11

Garnish with dried parsley if desired and serve hot. Enjoy!
