How to Make It
Preheat your oven to 350°F (175°C).
In a large bowl, mix the cooked rice, broccoli, cheese, cream of mushroom soup, milk, garlic powder, onion powder, salt, and pepper.
Transfer the mixture to a baking dish and spread it evenly.
If using, sprinkle breadcrumbs on top for a crispy finish.
Bake for 25-30 minutes, until bubbly and golden on top.
