Preheat your oven to 350°F and grease a 9x13-inch baking dish.

In a large skillet over medium-high heat, brown the ground beef with the diced onion until cooked through, about 6–8 minutes. Drain excess fat, then stir in the minced garlic and cook for 1 more minute.

Add Worcestershire sauce, garlic powder, salt, and pepper to the beef mixture. Stir to combine.

In a large bowl, mix together the cream of mushroom soup, sour cream, beef broth, and uncooked rice until well combined.

Stir the beef mixture into the bowl and fold everything together.

Pour into your prepared baking dish and top with 1 cup of the shredded cheddar.

Cover tightly with aluminum foil and bake for 25 minutes.

Remove the foil, sprinkle the remaining ½ cup of cheese on top, and bake uncovered for another 5 minutes until the cheese is golden and bubbly.

Let it rest for 5 minutes before serving. Garnish with fresh parsley if you like.
