Learn how to make delicious Chicken Spaghetti Casserole. Easy recipe with step-by-step instructions.

  • Total Time: 45 minutes
  • Yield: 4 servings 1x

Ingredients

Scale

  • 12 ounces spaghetti
  • 2 tablespoons olive oil
  • 1 pound boneless, skinless chicken breasts, cubed
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • 1 teaspoon garlic powder
  • 1 teaspoon onion powder
  • 1 bell pepper, diced
  • 1 cup mushrooms, sliced
  • 1 can (14.5 ounces) diced tomatoes, drained
  • 1 cup chicken broth
  • 1 cup heavy cream
  • 2 cups shredded cheddar cheese
  • 1/2 cup grated Parmesan cheese
  • 1 tablespoon fresh parsley, chopped

Feel free to substitute the chicken with turkey or even tofu for a vegetarian twist. If you’re out of cheddar, mozzarella or Monterey Jack can add a delightful creaminess.

Instructions

  1. Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish and set aside.
  2. Cook the spaghetti according to package instructions until al dente. Drain and set aside.
  3. In a large skillet over medium heat, heat the olive oil. Add the chicken, salt, pepper, garlic powder, and onion powder. Cook until the chicken is browned and cooked through, about 5-7 minutes.
  4. Add the bell pepper and mushrooms to the skillet and sauté until softened, about 5 minutes.
  5. Stir in the diced tomatoes, chicken broth, and heavy cream. Bring to a simmer and cook for 5 minutes, allowing the flavors to meld.
  6. Remove from heat and stir in the cooked spaghetti, 1 cup of cheddar cheese, and all of the Parmesan cheese. Mix until well combined.
  7. Transfer the mixture to the prepared baking dish. Top with the remaining cheddar cheese.
  8. Bake in the preheated oven for 20-25 minutes, or until the cheese is melted and bubbly.
  9. Garnish with fresh parsley before serving.

A tip from Mama Lou: Always let the casserole sit for a few minutes after baking. This helps the flavors settle and makes serving easier.
