Ingredients

Scale
  • 12 oz spaghetti

  • 2 cups cooked chicken, shredded (rotisserie works great)

  • 1 tablespoon butter or olive oil

  • 1/2 cup onion, diced

  • 1/2 cup green bell pepper, diced

  • 2 cloves garlic, minced

  • 1 (10.5 oz) can cream of mushroom soup

  • 1 (10.5 oz) can cream of chicken soup

  • 1 (10 oz) can diced tomatoes with green chilies (like Rotel), undrained

  • 1/2 cup chicken broth (or water)

  • 2 cups shredded cheddar cheese (divided)

  • 1/2 teaspoon salt

  • 1/2 teaspoon black pepper

  • 1/2 teaspoon paprika (optional)

  • Chopped parsley (for garnish)


Instructions

  1. Preheat the oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish.

  2. Cook the spaghetti:
    Bring a large pot of salted water to a boil. Cook spaghetti until just al dente. Drain and set aside.

  3. Sauté the vegetables:
    In a large skillet, melt butter over medium heat. Add onion and bell pepper. Sauté for 3–4 minutes until softened. Add garlic and cook another 30 seconds.

  4. Make the sauce:
    Stir in cream of mushroom soup, cream of chicken soup, diced tomatoes with chilies, chicken broth, 1 ½ cups of shredded cheese, and seasonings. Mix until smooth and creamy.

  5. Combine:
    Add the cooked spaghetti and shredded chicken to the sauce. Toss everything together until well coated.

  6. Bake:
    Transfer the mixture to the prepared baking dish. Sprinkle the remaining 1/2 cup of cheese over the top. Bake uncovered for 25–30 minutes, until bubbly and golden.

  7. Serve:
    Let rest for 5 minutes. Garnish with chopped parsley and serve warm.

Notes

  • You can use cream of celery soup instead of one of the others.

  • Add cooked mushrooms, peas, or chopped spinach for more veggies.

  • This freezes well—assemble, cover tightly, and freeze before baking.
