Ingredients

Scale

  • 1 lb ground beef

  • 1 medium yellow onion, thinly sliced

  • 1 cup uncooked long-grain white rice

  • 2 cups beef broth (low-sodium recommended)

  • 1 can (10.5 oz) condensed French onion soup

  • 1 tbsp Worcestershire sauce

  • 1 tsp garlic powder

  • Salt and black pepper, to taste

  • 1 tbsp olive oil or butter

  • 1 cup shredded mozzarella cheese

  • 1 cup shredded Swiss or Gruyère cheese

Optional Add-ins:

  • 1/2 cup sliced mushrooms

  • 1/2 cup frozen peas or green beans

  • 1/2 tsp fresh thyme or rosemary (optional)

Instructions

  • Preheat oven to 350°F (175°C). Grease a 9×13-inch casserole dish and set aside.

  • In a large skillet over medium heat, heat olive oil or butter. Add sliced onions and cook for 15-20 minutes, stirring occasionally, until caramelized and golden brown.

  • Add ground beef to the skillet with the onions. Cook until browned and fully cooked through, about 6-8 minutes. Drain excess fat if necessary.

  • Stir in garlic powder, Worcestershire sauce, salt, and pepper. Mix well.

  • In a large bowl (or directly in the casserole dish), combine the cooked beef-onion mixture with uncooked rice, beef broth, and French onion soup. Mix thoroughly.

  • If using optional vegetables or herbs, fold them into the mixture.

  • Pour the mixture into the prepared casserole dish. Cover tightly with aluminum foil.

  • Bake for 45 minutes.

  • Remove foil, sprinkle mozzarella and Swiss (or Gruyère) cheese evenly over the top.

  • Return to oven and bake uncovered for another 10-15 minutes, until cheese is melted and bubbly and rice is tender.

  • Let the casserole rest for 5-10 minutes before serving.

Notes

  • For a vegetarian version, substitute beef with plant-based ground meat and use vegetable broth.

  • Pre-cooked rice can be used; reduce broth to 1/2 cup and bake uncovered until heated through.

  • This dish freezes well. Let it cool completely before wrapping and storing.
