Ingredients

Scale

Pasta:

  • 12 ounces uncooked spaghetti, broken in half

Sauce and Seasonings:

  • 1 can (10-3/4 ounces) condensed cream of chicken soup, undiluted
  • 1 can (10-3/4 ounces) condensed cream of mushroom soup, undiluted
  • 1 cup sour cream
  • 1/2 cup whole milk
  • 1/4 cup butter, melted, divided
  • 2 tablespoons dried parsley flakes
  • 1/2 teaspoon garlic powder
  • 1/2 teaspoon salt
  • 1/4 teaspoon pepper

Cheeses and Vegetables:

  • 2 cups shredded part-skim mozzarella cheese
  • 1 cup grated Parmesan cheese
  • 2 to 3 celery ribs, chopped
  • 1 medium onion, chopped
  • 1 can (4 ounces) mushroom stems and pieces, drained

Protein:

  • 5 cups cubed cooked chicken

Topping:

  • 11/2 cups crushed cornflakes

Instructions

  1. Preheat and Cook Pasta: Preheat your oven to 350°F (175°C). Cook the spaghetti according to the package directions until al dente, then drain thoroughly.
  2. Make the Sauce Mixture: In a large bowl, combine the undiluted cream of chicken soup, cream of mushroom soup, sour cream, whole milk, 2 tablespoons of the melted butter, dried parsley flakes, garlic powder, salt, and pepper. Stir until smooth and well combined.
  3. Add Cheese and Vegetables: Add the shredded mozzarella, grated Parmesan, chopped celery, chopped onion, and drained mushrooms to the sauce mixture. Stir to incorporate all ingredients evenly.
  4. Combine Chicken and Pasta: Fold in the cubed cooked chicken and the drained spaghetti carefully, making sure everything is well distributed through the creamy base.
  5. Prepare for Baking: Transfer the mixture into a greased 3-quart baking dish. The dish will be quite full, so use a dish with the appropriate capacity.
  6. Add Topping: In a small bowl, combine the crushed cornflakes with the remaining 2 tablespoons of melted butter, stirring to coat the flakes. Sprinkle this mixture evenly over the top of the casserole.
  7. Bake: Place the baking dish uncovered in the preheated oven and bake for 45 to 50 minutes or until the casserole is bubbly and the topping is golden brown.

Notes

  • Use cooked chicken you have on hand such as rotisserie or leftover roasted chicken for convenience.
  • Make sure the spaghetti is cooked al dente to avoid mushy pasta after baking.
  • Substitute cornflake topping with breadcrumbs or crushed crackers if desired.
  • Feel free to add vegetables like bell peppers or mushrooms for additional flavor and nutrition.
  • This dish can be prepared ahead and refrigerated before baking; just add extra baking time if starting from cold.
