Ingredients

Scale

Main Ingredients

  • 1 lb ground beef
  • 3 cups cooked white rice
  • 1 can (10.5 oz) condensed French onion soup
  • 1 cup sour cream
  • 2 cups shredded mozzarella cheese

Seasonings & Extras

  • 2 tbsp butter
  • 1 tsp onion powder
  • 1 tsp garlic powder
  • Salt, to taste
  • Black pepper, to taste
  • 1 tbsp chopped parsley (optional)

Instructions

  1. Brown the Ground Beef: In a large skillet, melt the butter over medium heat. Add the ground beef and cook until it is fully browned. Drain any excess fat to avoid greasiness.
  2. Season the Beef: Stir in onion powder, garlic powder, salt, and black pepper to the browned ground beef, mixing well to distribute the seasonings evenly.
  3. Combine the Casserole Mixture: In a mixing bowl, combine the cooked ground beef, cooked white rice, condensed French onion soup, and sour cream. Mix thoroughly until all ingredients are well incorporated.
  4. Prepare the Baking Dish: Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish to prevent sticking.
  5. Assemble the Casserole: Spread the combined mixture evenly in the greased baking dish. Sprinkle the shredded mozzarella cheese uniformly over the top.
  6. Bake the Casserole: Bake the dish uncovered in the preheated oven for 25–30 minutes, or until the cheese has melted, is bubbly, and slightly golden.
  7. Garnish and Serve: Remove the casserole from the oven and garnish with chopped parsley if desired. Serve warm for a delicious comforting meal.

Notes

  • You can substitute the mozzarella cheese with cheddar or a blend of cheeses for a different flavor.
  • For a lower-fat version, use lean ground beef and reduced-fat sour cream.
  • Cook rice ahead of time or use leftover rice for convenience.
  • Add some sautéed mushrooms or caramelized onions for extra depth of flavor.
  • The parsley garnish is optional but adds a fresh touch and color to the dish.
