Preheat your oven to 350°F (175°C). Grease a 9x13 inch baking dish with a little olive oil or cooking spray.
In a medium saucepan, bring the vegetable broth to a boil. Stir in the brown rice, cover, reduce heat to low, and let it simmer for about 45 minutes or until the rice is tender and liquid is absorbed.
While the rice is cooking, steam the broccoli florets until they are bright green and tender, about 5-7 minutes. Set aside.
In a large mixing bowl, combine the cooked rice, steamed broccoli, shredded cheddar cheese, cream of mushroom soup, milk, garlic powder, onion powder, black pepper, and salt. Mix until everything is well combined.
Pour the mixture into the prepared baking dish, spreading it out evenly.
In a small bowl, combine the breadcrumbs with olive oil and Parmesan cheese. Sprinkle the breadcrumb mixture over the rice and broccoli layer in the baking dish.
Bake in the preheated oven for 25-30 minutes, or until the top is golden brown and bubbly.
Once done, remove from the oven and let it cool for a few minutes before slicing. Garnish with fresh chopped parsley for an extra touch.
Notes
For a homemade cream of mushroom soup, sauté mushrooms and blend with cream.
