Creating Beef and Rice Casserole is easy if you follow these straightforward steps:

1. Preheat Your Oven: Start by preheating your oven to 350°F (175°C).

2. Brown the Beef: In a large skillet over medium heat, cook the ground beef until browned. Drain any excess grease.

3. Sauté the Vegetables: Add chopped onion and bell pepper to the skillet. Cook until they become tender, about 3-4 minutes.

4. Add Rice and Mix: Stir in the uncooked rice, diced tomatoes (with their juices), cream of mushroom soup, and beef broth.

5. Season: Sprinkle in garlic powder, onion powder, salt, and black pepper. Mix until well combined.

6. Incorporate Mixed Vegetables: Gently fold in the frozen mixed vegetables to add flavor and nutrition.

7. Transfer to Baking Dish: Pour the mixture into a greased casserole dish, spreading it evenly.

8. Cover and Bake: Cover the dish with foil and bake in the preheated oven for 30 minutes.

9. Add Cheese (Optional): If desired, remove the foil and sprinkle shredded cheddar cheese on top. Bake uncovered for an additional 10 minutes or until the cheese is melted and bubbly.

10. Cool and Serve: Once baked, let it sit for a few minutes before serving. This allows the casserole to set and makes it easier to scoop.
