Heat the oven to 350°F (175°C). Grease a 9x13-inch baking dish.

Cook the ground beef in a large skillet over medium-high heat, breaking it up as it cooks, until no pink remains, about 5-7 minutes. Drain excess fat.
03 -
Remove from heat. Stir in the French onion soup mix, condensed soup, beef broth, sour cream, Worcestershire sauce, garlic powder, and black pepper. Fold in the dry rice until evenly combined.
04 -
Pour the mixture into the prepared baking dish and spread into an even layer. Cover tightly with aluminum foil, pressing it down around all edges.
05 -
Bake for 50 minutes, until the rice has absorbed the liquid and is tender. Peel back a corner of the foil to check. If the rice still feels firm in the center, re-cover and bake another 5-8 minutes.
06 -
Remove the foil entirely. Scatter the shredded cheese evenly across the top, then add the crispy fried onions. Bake uncovered for 10 more minutes, until the cheese is melted and bubbling at the edges. Serve hot.
