How to Make It
Preheat your oven to 375°F (190°C).
In a large baking dish, combine the diced chicken, broccoli, cooked rice, cream of chicken soup, garlic powder, onion powder, salt, and pepper.
Mix everything together until well combined.
Sprinkle the shredded cheddar cheese on top of the mixture.
Bake in the oven for 25-30 minutes, until the chicken is cooked through and the cheese is bubbly.
