Main Ingredients

  • 8 ounces spaghetti Cooked to al dente
  • 1 pound chicken breast, cooked and shredded Rotisserie chicken works well
  • 1 can (10.5 ounces) cream of mushroom soup
  • 1 can (10.5 ounces) cream of chicken soup
  • 1 cup chicken broth Low-sodium recommended
  • 1 cup grated cheddar cheese Plus extra for topping, if desired

  • 1/4 cup chopped fresh parsley Optional, for garnish

Instructions
 

Preparation

  • Preheat your oven to 350°F (175°C). Grease a 9x13-inch or similar baking dish.
  • Cook the spaghetti according to package directions until just al dente. Drain well and set aside.
  • In a large skillet over medium heat, sauté the diced onion and bell pepper with a tablespoon of oil until softened, about 5 minutes. Season lightly with salt and pepper.
  • In a large mixing bowl, combine shredded chicken, cream of mushroom soup, cream of chicken soup, chicken broth, grated cheddar, and garlic powder. Stir until smooth.
  • Fold the cooked spaghetti and the sautéed onion/pepper into the chicken-and-soup mixture. Taste and adjust seasoning.
  • Pour the mixture into the prepared baking dish and spread into an even layer. Top with an extra sprinkle of cheddar if you like.
  • Bake for 25–30 minutes, until the casserole is bubbly and the top is lightly golden. Let rest 5 minutes, then garnish with parsley and serve.

Notes

This casserole is freezer-friendly and adaptable to ingredients on hand. For lighter options, consider reduced-fat soups and cheese. Enjoy with sides like salads or garlic bread.
