  • Total Time: 45 minutes
  • Yield: 6 servings

Ingredients

  • 12 oz spaghetti, uncooked
  • 2 cups cooked shredded chicken
  • 1 can (10.5 oz) cream of chicken soup
  • 1 can (10.5 oz) cream of mushroom soup
  • 1 cup sour cream
  • 2 cups shredded cheddar cheese, divided
  • ½ cup diced green bell pepper
  • ½ cup diced onion
  • 1 teaspoon garlic powder
  • 1 teaspoon paprika
  • Salt and black pepper to taste
  • ¼ cup chicken broth, optional

Instructions

  1. Preheat oven to 350°F (175°C) and lightly grease a 9×13-inch baking dish.
  2. Cook spaghetti in salted boiling water until al dente. Drain and set aside.
  3. Sauté diced onion and green bell pepper in a skillet with a little oil or butter until softened. Set aside.
  4. In a large bowl, mix cream of chicken soup, cream of mushroom soup, sour cream, garlic powder, paprika, salt, and black pepper. Stir in chicken broth if the mixture is too thick.
  5. Add cooked spaghetti, shredded chicken, sautéed vegetables, and 1½ cups of shredded cheddar cheese. Mix until well combined.
  6. Spread the mixture evenly into the prepared baking dish. Sprinkle remaining cheese on top.
  7. Bake uncovered for 25–30 minutes, until cheese is melted and bubbly.
  8. Let rest for a few minutes before serving.

Notes

  • Use rotisserie chicken for convenience and added flavor.
  • Swap cheddar with Monterey Jack or mozzarella for a different taste.
  • Add veggies like mushrooms or spinach for variety.
  • To lighten it up, use spaghetti squash instead of pasta.
  • This dish freezes well before baking; add extra time when baking from frozen.
