  • Total Time: 1 hour
  • Yield: 6 servings

Ingredients

Main Ingredients

  • 1 lb spaghetti cooked
  • 1 lb chicken shredded meat about 1 rotisserie chicken

Sauce and Cheese

  • 2 tablespoons unsalted butter
  • 1 lb Velveeta cheese cut into chunks
  • 1 cup milk
  • 1 10-ounce can original Rotel
  • 1 10-ounce can cream of mushroom soup
  • salt and pepper to taste

Topping

  • 1 cup shredded cheddar cheese
  • ½ cup panko bread crumbs
  • crushed red pepper flakes for serving

Instructions

  1. Prepare casserole dish and oven: Grease a 9×13 casserole dish with Crisco and set aside. Preheat oven to 350 degrees Fahrenheit.
  2. Make the cheese sauce: Combine butter, Velveeta cheese chunks, Rotel, cream of mushroom soup, and milk in a large stockpot. Cook over medium heat, stirring constantly, until the cheese has fully melted and the mixture is smooth.
  3. Combine chicken and spaghetti: Add shredded chicken, cooked spaghetti, salt, and pepper to the cheese sauce. Toss thoroughly to fully combine all ingredients.
  4. Assemble casserole: Pour the mixture into the prepared casserole dish and level the top with a spoon. Evenly sprinkle shredded cheddar cheese and panko bread crumbs on top.
  5. Bake covered: Cover the casserole with foil and bake for 30 minutes or until the cheese is hot and bubbling.
  6. Broil topping: Remove foil and broil for 3 to 5 minutes, watching carefully, until the breadcrumbs are lightly browned and crisp.
  7. Rest and serve: Remove casserole from oven and let it rest for five minutes. Sprinkle crushed red pepper flakes to taste before serving.

Notes

  • Using a rotisserie chicken saves time and adds flavor, but cooked shredded chicken breast can be substituted.
  • For extra spice, add additional crushed red pepper flakes into the cheese sauce.
  • If you prefer a creamier topping without breadcrumbs, substitute with extra shredded cheese.
  • To avoid burning breadcrumbs under the broiler, watch closely and remove as soon as they begin to brown.
  • This casserole can be prepared a day ahead; refrigerate before baking and increase baking time slightly if baking chilled.
