Description
A creamy, comforting baked pasta casserole made with tender shredded chicken, spaghetti, mushrooms, and a rich Parmesan cream sauce, topped with melty cheese and optional golden breadcrumbs.
Ingredients
12 oz spaghetti
3 cups cooked chicken breast, shredded
2 tablespoons butter
1 small onion, finely chopped
3 cloves garlic, minced
8 oz mushrooms, sliced
1/4 cup all-purpose flour
2 cups chicken broth
1 cup whole milk
1/2 cup sour cream
1 cup shredded mozzarella cheese
1/2 cup grated Parmesan cheese
1 teaspoon Italian seasoning
1/2 teaspoon salt
1/2 teaspoon black pepper
1/2 cup breadcrumbs (optional)
1 tablespoon chopped fresh parsley (for garnish)
Instructions
- Preheat oven to 350°F (175°C) and lightly grease a 9x13-inch baking dish.
- Cook spaghetti according to package instructions until al dente. Drain and set aside.
- In a large skillet, melt butter over medium heat. Add onion and cook until softened. Stir in garlic and mushrooms and cook until tender.
- Sprinkle flour over the mushroom mixture and stir continuously to form a roux.
- Slowly whisk in chicken broth and milk, stirring constantly until the sauce thickens.
- Remove from heat and stir in sour cream, mozzarella, Parmesan, Italian seasoning, salt, and pepper until smooth.
- In a large bowl, combine cooked spaghetti and shredded chicken. Pour sauce over and toss to coat evenly.
- Transfer mixture to prepared baking dish and spread evenly. Sprinkle breadcrumbs on top if using.
- Bake for 25–30 minutes, until bubbly and lightly golden.
- Garnish with chopped parsley before serving.
Notes
Use rotisserie chicken for convenience.
Add peas or steamed broccoli for extra vegetables.
Substitute part of the mozzarella with provolone for deeper flavor.
Use low-fat milk and reduced-fat sour cream for a lighter version.
Store leftovers in the refrigerator for up to 4 days or freeze for up to 2 months.
