  • Total Time: 1 hour 10 minutes
  • Yield: 8 servings

Ingredients

Main Ingredients

  • 1 lb lean ground beef
  • 1 medium yellow onion, diced
  • ½ teaspoon salt
  • ½ teaspoon pepper
  • 1 oz onion soup mix
  • 2 cups instant white rice, uncooked
  • 2 cups beef broth
  • 1 cup sour cream
  • 2 cups shredded mozzarella cheese
  • 1 cup crispy fried onions

Optional Topping

  • Fresh chopped parsley

Instructions

  1. Preheat Oven: Preheat your oven to 350°F (175°C) to prepare for baking the casserole.
  2. Cook Ground Beef and Onions: Place the ground beef in a large skillet over medium-high heat, breaking it apart as it cooks. Add diced onions and stir well. Cook until the beef is fully browned and the onions are tender.
  3. Season Meat Mixture: Add salt, pepper, and onion soup mix to the browned beef mixture. Stir thoroughly to coat the beef evenly. Remove the skillet from heat.
  4. Prepare Baking Dish: Spray a 9 x 13 inch baking dish with cooking spray to prevent sticking.
  5. Layer Rice: Spread the uncooked instant rice evenly across the bottom of the baking dish.
  6. Add Meat Mixture: Spoon the ground beef and onion mixture evenly over the rice layer.
  7. Pour Broth: Evenly pour the beef broth over the ground beef and rice layers to provide moisture for cooking the rice.
  8. Cover and Bake: Cover the dish tightly with aluminum foil and bake in the preheated oven for 40 minutes.
  9. Add Toppings: Remove the casserole from the oven and lift off the foil. Spoon sour cream evenly over the beef layer, then sprinkle shredded mozzarella cheese on top, followed by crispy fried onions.
  10. Finish Baking: Return the casserole to the oven, uncovered, and bake for another 10 to 15 minutes or until the cheese is fully melted and bubbly.
  11. Rest and Garnish: Let the casserole rest for a few minutes after baking. Sprinkle fresh chopped parsley on top if desired.
  12. Serve: Cut into servings and enjoy your comforting French Onion Ground Beef and Rice Casserole.

Notes

  • You can substitute the instant white rice with instant brown rice if preferred, but cooking times may vary slightly.
  • For a lower-fat version, use reduced-fat sour cream and mozzarella cheese.
  • If you prefer a spicier dish, add a pinch of cayenne pepper or chili flakes when seasoning the beef.
  • Leftovers can be stored in the refrigerator for up to 3 days and reheated in the oven or microwave.
  • Adding fresh chopped parsley at the end adds a fresh flavor and a pop of green color to the casserole.
