Chicken Spaghetti

Chicken Spaghetti is a baked casserole featuring cooked spaghetti combined with a creamy cheese sauce made from butter, onion, garlic, flour, milk, cheddar cheese, and cream cheese. The sauce coats shredded or diced chicken and diced tomatoes with chilies for added flavor, then is baked topped with more cheddar cheese to form a golden, melty crust.

Description

This recipe uses a white sauce base created by sautéing onions and garlic in butter, then thickened with flour and milk. Cheddar cheese and cream cheese are melted into the sauce, creating a rich, creamy mixture with balanced sharpness and smooth texture. Cooked spaghetti, chicken, and Ro-Tel tomatoes with chilies are folded into the sauce for combined flavors and textures.

Transferring the mixture to a sprayed baking dish and topping with additional cheddar cheese adds a browned cheesy crust once baked. The combination of pasta, chicken, and cheese sauce with tomato’s mild heat creates a comforting, flavorful one-dish meal suitable for family dinners.

Using freshly grated cheddar cheese helps the sauce melt smoothly, and cooked chicken can be roasted, shredded, leftover, or rotisserie style. Baking at 350 °F for 20-25 minutes melds flavors and melts the topping without overcooking.

Servings
  • 16 ounces spaghetti
  • 1/4 cup butter
  • 1/2 cup onion finely diced
  • 1 1/2 teaspoons garlic minced
  • 1/4 cup flour
  • 3 cups milk
  • 4 cups cheddar cheese divided use, shredded
  • 4 ounces cream cheese cut into 1 inch pieces.

  • 3 cups chicken diced or shredded, cooked
  • 10 ounce can diced tomatoes with chilies drained, Ro-Tel brand

Instructions

  1. Preheat the oven to 350 degrees F. Coat a 9"x13" pan with cooking spray.
  2. Cook the spaghetti in a large pot of salted water according to package directions.
  3. Melt the butter in a large skillet over medium heat. Add the onion and cook for 3-4 minutes or until softened.
  4. Add the garlic and cook for 30 seconds. Stir in the flour and cook for 1 minute.
  5. Slowly add the milk to the pan, whisking constantly.
  6. Bring the milk mixture to a simmer and cook for 3-4 minutes or until just thickened.
  7. Remove the sauce from the heat, and mix in 2 1/2 cups of cheddar cheese, along with the cream cheese. Stir until cheeses are melted. Season with salt and pepper to taste.
  8. Drain the spaghetti and return it to the cooking pot. Add the chicken and tomatoes to the pasta.
  9. Pour the cheese sauce over the pasta and toss to coat evenly.
  10. Place the pasta mixture into the prepared pan. Sprinkle the remaining 1 1/2 cups of cheddar cheese over the top.

Notes

  • Any cooked chicken works for this recipe: roasted, shredded, leftover, or rotisserie chicken can be used.
  • Use freshly grated cheddar cheese for the smoothest melt; pre-shredded cheese often contains anti-caking agents that affect texture.
