Ingredients

Scale

Main Ingredients

  • 1 lb ground beef
  • 1 cup long-grain white rice (uncooked)
  • 1 packet French onion soup mix
  • 2 cups beef broth
  • ½ cup sour cream
  • 1 ½ cups shredded mozzarella or Swiss cheese
  • ½ cup French-fried onions

Instructions

  1. Preheat Oven: Preheat the oven to 350°F (175°C) and grease a 9×13-inch baking dish to prevent sticking and ensure easy serving.
  2. Cook Ground Beef: In a skillet over medium heat, brown the ground beef until fully cooked, breaking it apart with a spatula. Drain any excess grease. Season the beef with salt, pepper, and garlic powder to enhance the flavor.
  3. Mix Rice and Soup Base: In a large bowl, combine the uncooked rice, French onion soup mix, and beef broth. Stir well to evenly distribute the soup mix.
  4. Combine Ingredients: Stir the cooked, seasoned ground beef and sour cream into the rice mixture until all components are thoroughly mixed, creating a creamy and flavorful base.
  5. Assemble Casserole: Transfer the mixture into the prepared baking dish, spreading it evenly. Sprinkle the shredded mozzarella or Swiss cheese evenly over the top.
  6. Bake Covered: Cover the dish with aluminum foil and bake in the preheated oven for 40 minutes, allowing the rice to cook through and flavors to meld.
  7. Bake Uncovered: Remove the foil and continue baking for an additional 10-15 minutes, or until the cheese is melted and bubbly.
  8. Add Topping and Final Bake: Sprinkle the French-fried onions evenly over the cheesy surface, then bake for another 5 minutes until the onions turn golden brown and crispy.

Notes

  • To ensure the rice cooks evenly, do not pre-cook it; the baking process will cook it fully.
  • You can substitute mozzarella with Swiss cheese or a cheese blend for different flavor profiles.
  • Use lean ground beef to reduce excess fat and grease.
  • If desired, add mushrooms or other vegetables to the sautéed beef for extra nutrition and taste.
  • Let the casserole rest for 5 minutes after baking for easier serving.
