Instructions

1. Mix the filling — In a large bowl, combine the shredded chicken, broccoli, rice, cream of chicken soup, sour cream, 1 1/2 cups of the cheddar cheese, salt, and pepper.
2. Assemble — Spread the mixture into a greased 9×13-inch baking dish and top with the remaining cheese.
3. Add the topping — Mix the breadcrumbs with the melted butter and sprinkle evenly over the casserole.
4. Bake & serve — Bake at 375F (190C) for 30 minutes, until bubbly and golden. Let it rest for 5 minutes, then serve warm.

Tips

• Use rotisserie chicken to save even more time.
• Chop the broccoli into small, even pieces so it cooks through.
• For extra crunch, broil for the last 2 minutes — watch it closely so the topping doesn’t burn.
• Let the casserole rest 5 minutes before serving so it sets and slices cleanly.

Storage

Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in the oven at 350F (175C) until warmed through, or microwave individual portions.
