Ingredients

Scale
  • 1 tablespoon olive oil
  • 1.5 pounds ground beef
  • 1 large yellow onion, thinly sliced
  • 1 teaspoon dried thyme
  • 1/2 teaspoon black pepper
  • 1/2 teaspoon salt
  • 1 (10.5 ounce) can condensed cream of mushroom soup
  • 1 (10.5 ounce) can condensed cream of celery soup
  • 1 packet (1.25 ounces) dry onion soup mix
  • 2 cups cooked white rice
  • 1 cup beef broth
  • 1 cup shredded Swiss cheese
  • 1/2 cup crispy fried onions, for topping

Instructions

  1. Preheat your oven to 375 degrees Fahrenheit. Lightly grease a 9×13 inch baking dish.
  2. Heat the olive oil in a large skillet over medium heat. Add the sliced onion and cook, stirring occasionally, until the onions are soft and beginning to caramelize, about 10 to 15 minutes. Remove the onions from the skillet and set them aside.
  3. Add the ground beef to the same skillet. Cook over medium-high heat, breaking it up with a spoon, until it is fully browned. Drain off any excess grease from the beef.
  4. Return the caramelized onions to the skillet with the ground beef. Stir in the dried thyme, salt, and pepper. Cook for one minute until fragrant.
  5. In a large bowl, whisk together the cream of mushroom soup, cream of celery soup, and the dry onion soup mix until smooth.
  6. Stir the cooked rice and beef mixture into the soup mixture. Add the beef broth and mix well to combine all ingredients.
  7. Spread the beef and rice mixture evenly into the prepared baking dish.
  8. Cover the dish tightly with aluminum foil. Bake for 25 minutes.
  9. Remove the foil. Sprinkle the shredded Swiss cheese evenly over the top of the casserole.
  10. Return the dish to the oven, uncovered, and bake for another 10 to 15 minutes, or until the cheese is melted and bubbly.
  11. Sprinkle the crispy fried onions over the melted cheese before serving. Let the casserole rest for 5 minutes before you cut and serve portions.

Notes

  • You can use pre-cooked rice to save time on a busy weeknight.
  • For a richer flavor, substitute 1/2 cup of the beef broth with dry red wine and let it cook down slightly with the beef.
  • If you do not have cream of celery soup, you can substitute it with an equal amount of cream of chicken soup.
