  • 1 can (10.5 oz) cream of mushroom soup (room temperature)
  • 1 can (10 oz) Rotel diced tomatoes and green chilies (do not drain unless you want less liquid)
  • 2 cups shredded cheddar cheese (divided; 1 1/2 cups mixed into the casserole, 1/2 cup for topping)
  • 1/2 cup chicken broth (low-sodium preferred)

Instructions

  • Preheat your oven to 350°F (175°C) and lightly grease a 9×13-inch baking dish with butter or cooking spray.

  • Add garlic powder, onion powder, salt, and pepper to the soup mixture, stirring well to blend all the flavors evenly.
  • Fold in the shredded cooked chicken, cooked spaghetti, and chicken broth until all ingredients are thoroughly combined.
  • Stir in 1 1/2 cups of shredded cheddar cheese so it is evenly mixed throughout the casserole filling.
  • Pour the mixture into the prepared baking dish, spreading it out evenly and smoothing the top with a spatula.
  • Sprinkle the remaining 1/2 cup of shredded cheddar cheese over the top of the casserole for a cheesy crust.
  • Bake in the preheated oven for 25 to 30 minutes, or until the cheese on top is fully melted, bubbly, and slightly golden brown.
  • Remove from the oven and let the casserole sit for a few minutes before serving.
  • Serve warm and enjoy this comforting, cheesy chicken spaghetti dish!
