Creating Hamburger Rice Casserole is an easy and straightforward process. Follow these steps for a delicious outcome:

1. Preheat the Oven: Begin by preheating your oven to 350°F (175°C).
2. Brown the Beef: In a large skillet, cook the ground beef over medium heat until browned. Drain any excess fat.
3. Sauté Vegetables: Add the diced onion and bell pepper to the skillet. Cook until softened, about 5 minutes.
4. Combine Ingredients: Stir in the rice, beef broth, cream of mushroom soup, diced tomatoes, garlic powder, onion powder, Italian seasoning, and salt and pepper. Mix until well combined.
5. Transfer to Casserole Dish: Pour the mixture into a greased 9×13-inch baking dish, and spread it evenly.
6. Cover with Foil: Cover the dish tightly with aluminum foil to keep moisture in while it bakes.
7. Bake: Place the dish in the preheated oven and bake for 30-35 minutes or until the rice is tender and has absorbed most of the liquid.
8. Add Cheese: Remove from the oven, uncover, and sprinkle shredded cheese over the top. Return to the oven and bake uncovered for another 5-10 minutes until the cheese is melted and bubbling.
9. Garnish and Serve: Once cooked, allow it to sit for a few minutes. Garnish with fresh parsley if desired, and serve warm.

These steps ensure you end up with a delicious Hamburger Rice Casserole that everyone will love.
