Creating Ground Beef & Rice Casserole is straightforward when you follow these steps:

1. Preheat Your Oven: Begin 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 fat.
3. Add Vegetables: Stir in the chopped onion and minced garlic. Sauté until they are soft and translucent.
4. Combine Ingredients: In the skillet, add the rice, diced tomatoes (with juices), cream of mushroom soup, mixed vegetables, beef broth, Worcestershire sauce, salt, black pepper, and paprika. Mix thoroughly until combined.
5. Transfer to Baking Dish: Pour the mixture into a greased 9×13-inch baking dish, spreading it evenly.
6. Cover and Bake: Cover the dish with aluminum foil and bake in the preheated oven for 25 minutes.
7. Uncover and Add Cheese: Remove the foil and sprinkle shredded cheese on top. Bake for an additional 15-20 minutes, or until the rice is tender and the cheese is melted.
8. Let It Rest: Once finished, remove the casserole from the oven and let it sit for 5-10 minutes. This cooling period helps it set, making it easier to serve.
9. Serve and Enjoy: Dish out portions and savor this incredible comfort food!
