Step 1

Preheat your oven to 350 degrees.  Spray a 9 by 13 inch casserole dish with cooking spray.

Step 2

In a large sauce pan, melt the butter. Add the onion, and cook until translucent, about 5 minutes.  Stir in the broccoli, and cook until no longer frozen, about 5 minutes.

Step 3

In a large bowl, whisk together the condensed cream of chicken soup, milk, onion powder, garlic powder, salt, and pepper. Stir in the broccoli onion mixture, diced chicken, instant rice, and 1 cup of cheddar cheese. Pour into the prepared casserole dish.

Step 4

Top with remaining cheese and fried onions. Bake covered for 30 minutes. Remove foil and continue baking for 15 minutes.
