Preheat your oven to 375°F (190°C) and grease a 9x13-inch baking dish with vegetable or olive oil.
Bring a large pot of salted water to a boil and cook the spaghetti according to the package instructions until al dente. Drain and set aside.
In a medium saucepan over medium heat, melt the butter. Sprinkle in the flour and whisk continuously for 1-2 minutes to form a roux.
Slowly pour in the chicken broth and milk, whisking constantly to avoid lumps. Cook until the mixture has thickened, about 3-4 minutes.
Add the cream cheese to the saucepan and stir until melted and smooth.
Stir in the diced tomatoes with green chilies, garlic powder, onion powder, salt, and black pepper. Simmer for 2-3 minutes to combine the flavors.
In a large mixing bowl, combine the cooked spaghetti, shredded chicken, sauce mixture, and 1 cup of shredded cheddar cheese. Toss until evenly coated.
Transfer the mixture to the prepared baking dish, spreading it out evenly.
Sprinkle the remaining shredded cheddar cheese and mozzarella cheese evenly over the top.
Bake in the preheated oven for 25-30 minutes, or until the cheese on top is bubbly and golden brown.
Allow the casserole to cool for 5 minutes before serving. Garnish with fresh parsley, if desired. Enjoy!
