Ingredients

Scale
  • 2 cups cooked white rice
  • 2 cups cooked, shredded chicken breast
  • 1 (10.5 ounce) can condensed cream of chicken soup
  • 1 (10.5 ounce) can condensed cream of mushroom soup
  • 1 cup mayonnaise
  • 1 cup sour cream
  • 1 teaspoon onion powder
  • 1 teaspoon garlic powder
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper
  • 1 cup milk
  • 1 (10 ounce) package frozen broccoli florets, thawed and drained
  • 2 cups shredded sharp cheddar cheese, divided
  • 1/2 cup crushed butter crackers (optional, for topping)
  • 2 tablespoons melted butter (if using cracker topping)

Instructions

  1. Preheat your oven to 375 degrees Fahrenheit. Lightly grease a 9×13 inch baking dish.
  2. In a large bowl, combine the cream of chicken soup, cream of mushroom soup, mayonnaise, sour cream, onion powder, garlic powder, salt, and pepper. Whisk until the mixture is smooth.
  3. Stir in the milk until the sauce is well combined.
  4. Gently fold in the cooked rice, shredded chicken, thawed broccoli, and 1 1/2 cups of the shredded cheddar cheese. Mix until all ingredients are evenly coated in the creamy sauce.
  5. Transfer the mixture into your prepared baking dish, spreading it into an even layer.
  6. In a small bowl, mix the remaining 1/2 cup of cheddar cheese with the crushed butter crackers and melted butter, if you are using a topping. Sprinkle this mixture evenly over the casserole.
  7. Bake for 30 to 35 minutes, or until the casserole is hot throughout and the topping is golden brown.
  8. Let the casserole rest for 5 minutes before you serve it.

Notes

  • For a make-ahead option, assemble the entire casserole, cover it tightly with foil, and refrigerate for up to 24 hours. Add 10 to 15 minutes to the baking time if baking directly from the refrigerator.
  • You can use leftover rotisserie chicken for faster prep time.
  • If you prefer a lighter version, substitute half the mayonnaise with plain Greek yogurt.
