  • Preheat oven to 425 degrees F.
  • In a saucepan, bring the water to a boil with half of the salt, reduce the heat, cover, and simmer for about 45 minutes, until the rice is tender and has absorbed the water.
  • When rice cooks and is about halfway done, butter casserole dish. In a large pot, melt 3 tablespoons butter and flour over medium heat until golden in color to make a quick roux.
  • Add mushrooms, onion, garlic, garlic powder, cayenne pepper, heavy cream, and vegetable broth. Add broccoli, half of the cheese, and rice. Season with salt and pepper, to taste.
  • Pour into buttered dish and top with remaining shredded cheese. Bake until cheese is melted and golden, about 20 minutes.
