Ingredients
Scale
1 lb spaghetti, cooked al dente
2–3 cups cooked chicken (shredded or diced), such as rotisserie chicken
1 tbsp olive oil
1 medium onion, chopped
1 bell pepper (any color), chopped
1 (10.5 oz) can cream of mushroom soup or cream of chicken soup
1/2 cup sour cream or cream cheese, softened
1/2 cup chicken broth
2 cups shredded Sharp cheddar cheese, plus more for topping
Salt and black pepper to taste
Optional: Red pepper flakes, diced jalapeño, corn, peas, spinach, carrots, roasted broccoli, smoked gouda, Monterey Jack cheese
Instructions
Preheat your oven to 375°F (190°C).
Cook spaghetti according to package directions until al dente. Drain and set aside.
In a large skillet or Dutch oven, heat olive oil over medium heat. Add chopped onion and bell pepper and sauté until tender, about 5-7 minutes. If adding other vegetables like carrots, incorporate them here.
Stir in the cream of mushroom/chicken soup, sour cream or softened cream cheese, and chicken broth. Whisk until smooth. If using cream cheese, ensure it’s fully melted and incorporated.
Gradually add 2 cups of shredded cheddar cheese to the sauce, stirring until melted and smooth. Season with salt and black pepper to taste. For a spicy kick, add red pepper flakes or diced jalapeño.
In a large bowl, combine the cooked al dente spaghetti with the cooked chicken. Pour the creamy cheese sauce over the spaghetti and chicken mixture and stir gently until everything is well coated.
Transfer the mixture into a 9×13 inch baking dish. Ensure even distribution. Sprinkle the remaining shredded cheese generously over the top of the casserole.
Bake in the preheated oven for 25-35 minutes, or until the sauce is bubbly around the edges and the cheese on top is melted and golden brown. If the top browns too quickly, you can loosely cover it with foil.
Remove from the oven and let the casserole rest for 10-15 minutes before serving. This allows the sauce to set and makes for easier, cleaner portions. Garnish with fresh parsley or green onions if desired.
Serve warm with your favorite side dishes, such as a green salad or garlic bread.
