  • 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 shredded cheddar cheese divided use
  • 4 ounces cream cheese cut into 1 inch pieces.
  • salt and pepper to taste
  • 3 cups cooked chicken diced or shredded
  • 10 ounce can Ro-Tel tomatoes with chilies drained
  • 2 tablespoons chopped parsley

Instructions

  • Preheat the oven to 350 degrees F. Coat a 9"x13" pan with cooking spray.
  • Cook the spaghetti in a large pot of salted water according to package directions.
  • Melt the butter in a large skillet over medium heat. Add the onion and cook for 3-4 minutes or until softened.
  • Add the garlic and cook for 30 seconds. Stir in the flour and cook for 1 minute.
  • Slowly add the milk to the pan, whisking constantly.
  • Bring the milk mixture to a simmer and cook for 3-4 minutes or until just thickened.
  • 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.
  • Drain the spaghetti and return it to the cooking pot. Add the chicken and tomatoes to the pasta.
  • Pour the cheese sauce over the pasta and toss to coat evenly.
  • Place the pasta mixture into the prepared pan. Sprinkle the remaining 1 1/2 cups of cheddar cheese over the top.
  • Bake for 20-25 minutes, until casserole is bubbly and cheese is melted. Sprinkle with parsley, then serve.
