Instructions

Preheat your oven to 350°F. Cook the spaghetti according to package directions until al dente. Drain well.
In a large mixing bowl, combine the cream of chicken soup, undrained diced tomatoes and green chilies, sour cream, chicken broth, garlic powder, onion powder, and cayenne pepper. Stir until smooth and well-combined.
Add the cooked spaghetti, shredded chicken, 1 cup of cheddar cheese, and cubed Velveeta to the sauce. Gently fold everything together until evenly coated.
Transfer the mixture to a greased 9×13 inch baking dish. Spread into an even layer.
Sprinkle the remaining 1 cup of cheddar cheese and Parmesan cheese evenly over the top.
Bake for 25-30 minutes, or until cheese is melted and casserole is bubbly around the edges. For a golden top, broil for the last 1-2 minutes, watching carefully.
Let the casserole rest for about 5 minutes before serving. Garnish with fresh parsley if desired.

Notes

Smart Swaps: Use gluten-free pasta and soup for gluten-free version. For lower fat, substitute low-fat dairy products. Adjust spice level by using mild or hot Rotel and increasing/decreasing cayenne pepper. Do not overcook the pasta as it will continue cooking in the oven. Letting the casserole rest after baking helps the sauce set for easier serving.
