Creating the Cheesy Hamburger Rice Casserole is straightforward. Follow these easy steps for a delightful meal:

1. Preheat the Oven: Start by preheating your oven to 350°F (175°C).
2. Brown the Beef: In a large skillet over medium heat, add the ground beef and diced onion. Cook until the meat is browned and the onions are translucent, about 5-7 minutes.
3. Season: Add garlic powder, onion powder, salt, and pepper to the meat mixture, stirring well to combine.
4. Combine Ingredients: In a large mixing bowl, combine the browned beef mixture with the uncooked rice, cream of mushroom soup, diced tomatoes (with juices), and beef broth. Mix everything until well combined.
5. Transfer to Casserole Dish: Pour the prepared mixture into a greased 9×13-inch baking dish. Spread it out evenly.
6. Add Cheese: Top the casserole with 1 ½ cups of shredded cheddar cheese, spreading it evenly over the top.
7. Cover and Bake: Cover the baking dish with aluminum foil and bake in the preheated oven for 30 minutes.
8. Uncover and Continue Baking: Remove the foil and bake for an additional 15 minutes, or until the cheese is melted and bubbly.
9. Garnish: Remove from the oven and let it sit for 5-10 minutes. Finish by garnishing with fresh parsley if desired.
