Preheat your oven to 375°F (190°C) and grease a 9x13-inch baking dish with cooking spray or butter.

In a large skillet over medium-high heat, brown the ground beef, breaking it apart with a spoon as it cooks, about 6-8 minutes until no pink remains.

Add the diced onion to the skillet with the beef and cook for 4-5 minutes until the onion becomes translucent and fragrant.

Stir in the minced garlic and cook for an additional 30 seconds until aromatic.

Add the uncooked rice to the skillet and stir to combine with the beef mixture, cooking for 2 minutes to lightly toast the rice.

Pour in the beef broth, Worcestershire sauce, garlic powder, paprika, black pepper, and salt, stirring everything together thoroughly.

Transfer the entire mixture to your prepared baking dish, spreading it evenly across the bottom.

Cover the dish tightly with aluminum foil and bake for 25 minutes.

Remove from oven, take off the foil, and sprinkle the shredded cheddar cheese evenly over the top.

Return to the oven, uncovered, and bake for an additional 15-20 minutes until the cheese is melted, bubbly, and golden brown.

Let the casserole rest for 5 minutes before serving, then garnish with fresh chopped parsley.

Serve hot and enjoy this comforting, satisfying meal that's sure to become a family favorite.
