Ingredients

Scale
  • 1 pound ground beef
  • 1 medium yellow onion, finely chopped
  • 1 teaspoon dried thyme
  • 1 teaspoon garlic powder
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper
  • 1 (10.5 ounce) can condensed cream of mushroom soup
  • 1 (10.5 ounce) can condensed cream of celery soup
  • 1 (10 ounce) can French onion soup, undiluted
  • 1 cup beef broth
  • 1 cup uncooked long-grain white rice
  • 1 cup shredded Swiss cheese
  • 1/2 cup shredded mozzarella cheese
  • 1/4 cup crispy fried onions (for topping)

Instructions

  1. Preheat your oven to 375 degrees Fahrenheit. Lightly grease a 9×13 inch baking dish.
  2. In a large skillet over medium heat, cook the ground beef, chopped onion, thyme, garlic powder, salt, and pepper. Cook until the beef is browned and the onion is soft, about 8 minutes. Drain off any excess grease.
  3. Stir the cream of mushroom soup, cream of celery soup, French onion soup, beef broth, and uncooked rice into the skillet with the beef mixture. Mix well to combine all ingredients.
  4. Pour the entire mixture evenly into the prepared baking dish. Cover the dish tightly with aluminum foil.
  5. Bake covered for 45 minutes.
  6. Remove the foil. Sprinkle the Swiss cheese and mozzarella cheese evenly over the top of the casserole.
  7. Return the dish to the oven, uncovered, and bake for an additional 10 to 15 minutes, or until the cheese is melted and bubbly and the rice is tender.
  8. Remove from the oven. Sprinkle the crispy fried onions over the melted cheese layer. Let the casserole rest for 5 minutes before serving.

Notes

  • You can substitute the Swiss cheese with Gruyère for a more authentic French onion flavor.
  • If you want a creamier texture, substitute 1/2 cup of the beef broth with 1/2 cup of sour cream, stirring it in with the condensed soups.
  • This casserole freezes well. Assemble the entire dish (without the final cheese and onion topping), cover tightly, and freeze for up to 3 months. Thaw overnight in the refrigerator before baking as directed, adding about 15 minutes to the covered baking time.
