Start by thawing the broccoli and microwaving it for about 5 minutes. Make sure to drain it thoroughly and cut any large florets into bite-sized pieces.

In a mixing bowl, combine warm cooked rice, diced onion, cream of mushroom soup, milk, salt, pepper, garlic powder, paprika, and 1 cup of shredded cheddar. Stir until well combined, then gently fold in the broccoli.

Transfer the mixture into a greased 9x13-inch baking dish and sprinkle the remaining 1 cup of shredded cheddar cheese on top.

Bake at 350℉ for 35 - 40 minutes until it's bubbling and the cheese is just starting to develop a golden brown hue. Enjoy!
