Heat the oven to 375°F. Simmer the rice in the broth, covered, for 15 minutes until tender. Meanwhile shred about 3 cups of rotisserie chicken.
Microwave the frozen broccoli 3-4 minutes until thawed and chop any big pieces.
In a large bowl stir together the cooked rice, chicken, broccoli, sour cream, milk, 1.5 cups cheddar, garlic powder, onion powder, salt, and pepper.
Spread in a greased 9x13 dish and top with the remaining cheddar.
Bake 15 minutes until bubbly, the cheese is melted, and the center is heated through to 165°F. Let it sit 5 minutes before serving.
Make-ahead: assemble, cover, and refrigerate up to a day; add 10 minutes to the bake time.
