  • Total Time: 1 hour 15 minutes
  • Yield: 8 servings

Ingredients

Pasta and Sauce

  • 16 ounces spaghetti noodles
  • 10 ounces cream of chicken soup
  • 10 ounces cream of mushroom soup
  • 1 cup chunky salsa
  • 1 teaspoon black pepper
  • 1 teaspoon garlic powder
  • 0.75 cup reserved pasta water

Chicken and Cheese

  • 3 cups shredded cooked chicken
  • 3 cups shredded cheese, divided

Instructions

  1. Preheat Oven: Preheat your oven to 350°F (175°C) and grease a 9×13-inch baking dish with cooking spray to prevent sticking; set aside.
  2. Cook Spaghetti: Boil the spaghetti noodles until al dente according to package instructions. When draining, reserve 3/4 cup of the pasta water to add moisture and flavor to the casserole.
  3. Mix Ingredients: In a large bowl, combine the cream of chicken soup, cream of mushroom soup, chunky salsa, black pepper, garlic powder, shredded cooked chicken, reserved pasta water, the cooked spaghetti noodles, and 1 1/2 cups of shredded cheese. Stir well until everything is evenly coated.
  4. Assemble Casserole: Pour the mixture into the prepared baking dish, spreading it out evenly. Sprinkle the remaining 1 1/2 cups of shredded cheese evenly over the top.
  5. Bake Covered: Cover the casserole with aluminum foil and bake in the preheated oven for 30 minutes. This step allows the flavors to meld and the casserole to heat through.
  6. Bake Uncovered: Remove the foil and continue baking for another 15-20 minutes, or until the casserole is bubbly around the edges and the cheese on top is fully melted and starting to brown slightly.

Notes

  • You can use leftover rotisserie chicken or boiled chicken breasts shredded finely for ease.
  • Chunky salsa adds texture and flavor; mild or medium works well depending on your spice preference.
  • If you prefer, substitute the canned soups with homemade cream sauces for a fresher taste.
  • Let the casserole rest 5-10 minutes before serving to set and make portioning easier.
  • This dish stores well in the refrigerator for 3-4 days and can be reheated in the oven or microwave.
