Ingredients
  

  • 12 ounces spaghetti
  • 2 cups cooked shredded chicken

  • 1 can cream of chicken soup

  • 8 ounces cream cheese softened
  • 2 cups shredded cheddar cheese divided
  • 1 teaspoon Italian seasoning
  • 1 teaspoon onion powder
  • 1 teaspoon garlic powder
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • 1 cup diced tomatoes drained
  • 2 tablespoons chopped parsley

Equipment

  • 9 x 13 inch baking dish
  • Large pot
  • Large skillet

Method
 

  1. Preheat the oven to 350°F. Lightly grease a 9 x 13 inch baking dish.
  2. Bring a large pot of salted water to a boil. Cook the spaghetti until just al dente according to package instructions. Drain and set aside.
  3. Heat olive oil in a large skillet over medium heat. Add diced onion and cook for 4 to 5 minutes until softened. Stir in garlic and cook for 30 seconds.
  4. Add cream of chicken soup, cream of mushroom soup, chicken broth, sour cream, and cream cheese to the skillet. Stir until smooth and creamy.
  5. Mix in 1 1/2 cups cheddar cheese, Italian seasoning, onion powder, garlic powder, salt, black pepper, and diced tomatoes.
  6. Fold in the shredded chicken and cooked spaghetti until evenly coated.
  7. Transfer the mixture to the prepared baking dish and spread evenly. Top with the remaining cheddar cheese.
  8. Bake uncovered for 30 to 35 minutes until hot and bubbly and the cheese is melted.
  9. Sprinkle with chopped parsley before serving.

Notes

For extra creamy texture, allow the casserole to rest for 10 minutes before serving so the sauce thickens slightly.
