Creating a delicious Ground Beef & Rice Casserole is straightforward and enjoyable if you follow these steps:

1. Preheat the Oven: Set your oven to 375°F (190°C) to prepare for baking.
2. Cook the Ground Beef: In a large skillet over medium heat, brown the ground beef until no longer pink. Drain excess fat if necessary.
3. Add Aromatics: Add diced onions, bell peppers, and garlic to the skillet. Cook until vegetables are soft, about 5 minutes.
4. Combine Ingredients: Stir in rice, beef broth, diced tomatoes, Worcestershire sauce, salt, pepper, oregano, and paprika. Mix thoroughly.
5. Transfer to Baking Dish: Pour the mixture into a greased 9×13 inch baking dish, spreading evenly.
6. Bake: Cover the dish with aluminum foil and bake for 25 minutes in the preheated oven.
7. Add Cheese: Remove the foil and sprinkle the shredded cheese over the top. Bake uncovered for an additional 10 minutes, or until the cheese is melted and bubbly.
8. Garnish and Serve: Once cooked, remove from the oven and let cool slightly. Sprinkle fresh parsley on top before serving.

These steps will ensure that your Ground Beef & Rice Casserole turns out flavorful and enjoyable.
