Method
 

Prepare the Base Ingredients
  1. Make sure your cooked chicken and rice are ready to go. If using frozen broccoli, thaw and drain it; fresh broccoli can be lightly steamed for 2–3 minutes so it stays vibrant and crisp-tender.
Make the Creamy Cheese Sauce
  1. In a skillet, melt butter and sauté diced onions until soft. Add garlic and cook briefly until fragrant. Sprinkle in flour and whisk to form a roux. Slowly pour in chicken broth and milk, whisking until the mixture thickens. Season with paprika, onion powder, salt, and pepper. Reduce heat and stir in half the cheddar cheese until melted.
Combine Everything Together
  1. In a large bowl, mix chicken, broccoli, rice, and the homemade cheese sauce. Make sure everything is evenly coated.
Transfer to a Baking Dish
  1. Spread the mixture into a greased 9×13-inch casserole dish and top with the remaining cheddar and mozzarella.
Add an Optional Crunchy Topping
  1. Mix crushed crackers or breadcrumbs with melted butter and sprinkle over the casserole for a golden, crisp finish.
Bake
  1. Bake uncovered at 375°F (190°C) for 25–30 minutes or until bubbling and golden on top.
Serve
  1. Let the casserole rest for a few minutes before slicing. Garnish with fresh parsley for a burst of color.
