Make this easy, cheesy chicken spaghetti casserole using rotisserie chicken and Rotel for a comforting, family-friendly weeknight dinner.

Ingredients

Scale
  • 1 pound spaghetti, broken into thirds
  • 2 cups cooked, shredded chicken (use rotisserie chicken for ease)
  • 1 (10.5 ounce) can cream of chicken soup
  • 1 (10.5 ounce) can cream of mushroom soup
  • 1 (10 ounce) can diced tomatoes and green chilies (Rotel), undrained
  • 1 cup sour cream
  • 1 cup milk
  • 1 cup shredded Monterey Jack cheese
  • 1 cup shredded sharp cheddar cheese
  • 1 cup Velveeta cheese, cubed
  • 1 (4 ounce) can diced green chilies, drained
  • 1 teaspoon garlic powder
  • 1/2 teaspoon onion powder
  • 1/4 teaspoon black pepper
  • 1 cup shredded Colby Jack cheese, for topping

Instructions

  1. Preheat your oven to 375 degrees Fahrenheit. Lightly grease a 9×13 inch baking dish.
  2. Cook the spaghetti according to package directions until al dente. Drain well and set aside.
  3. In a large bowl, combine the cream of chicken soup, cream of mushroom soup, Rotel, sour cream, milk, Monterey Jack cheese, cheddar cheese, Velveeta cheese, drained green chilies, garlic powder, onion powder, and pepper. Stir until the cheeses are mostly melted and the sauce is smooth.
  4. Add the cooked, drained spaghetti and the shredded chicken to the sauce mixture. Stir gently until everything is evenly coated.
  5. Pour the chicken spaghetti mixture into the prepared baking dish.
  6. Sprinkle the Colby Jack cheese evenly over the top of the casserole.
  7. Bake for 25 to 30 minutes, or until the casserole is bubbly and the top cheese is melted and lightly golden.
  8. Let the casserole rest for 5 minutes before you serve it. This is a quick comfort food dinner.

Notes

  • Using rotisserie chicken makes this a fast weeknight chicken meal.
  • For a Texas style chicken spaghetti flavor, increase the Rotel to one large can.
  • You can assemble this cheesy pasta bake ahead of time; cover and refrigerate for up to 24 hours before baking. Add 10 minutes to the bake time if cooking directly from the refrigerator.
