Ingredients

• 12 oz spaghetti
• 6 tbsp butter
• 1 cup all-purpose flour
• 4 cups chicken broth
• 2 cups whole milk
• 4 cups cooked, shredded chicken
• 8 oz sliced mushrooms
• 1 cup grated Parmesan cheese
• 1 cup shredded cheddar cheese
• 1 cup sour cream
• 1 tsp salt
• 0.5 tsp black pepper
• 0.5 tsp garlic powder
• 1 tbsp olive oil
• 1 cup breadcrumbs
• 2 tbsp chopped parsley (optional, for garnish)

Directions

Step 1

Preheat your oven to 350°F (175°C) and grease a 9x13-inch baking dish.

Step 2

Cook the spaghetti according to package instructions until al dente. Drain and set aside.

Step 3

In a large skillet, heat 1 tablespoon of olive oil over medium heat. Add the sliced mushrooms and sauté until tender, about 5-7 minutes. Remove from heat and set aside.

Step 4

In a medium saucepan, melt 6 tablespoons of butter over medium heat. Whisk in the flour and cook for 1-2 minutes, stirring constantly, to make a roux.

Step 5

Gradually whisk in the chicken broth and milk. Cook, stirring constantly, until the sauce thickens, about 5 minutes.

Step 6

Stir in the Parmesan cheese, salt, pepper, and garlic powder. Remove the pan from heat.

Step 7

In a large mixing bowl, combine the cooked spaghetti, shredded chicken, sautéed mushrooms, sour cream, and cheddar cheese. Pour the sauce over the mixture and stir to combine evenly.

Step 8

Transfer the mixture into the prepared baking dish and spread it out evenly.

Step 9

Sprinkle the breadcrumbs evenly over the top of the casserole.

Step 10

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

Step 11

Remove from the oven and let the casserole rest for 5-10 minutes before serving.

Step 12

Garnish with chopped parsley, if desired, and serve warm at your potluck or family meal.
