Ingredient You Will Need

To make this delightful casserole, gather these simple ingredients:

  • 1 lb ground beef
  • 1 cup long-grain white rice (uncooked)
  • 1 packet French onion soup mix
  • 2 cups beef broth
  • ½ cup sour cream
  • 1 ½ cups shredded mozzarella or Swiss cheese
  • ½ cup French-fried onions
  • 1 tbsp butter
  • ½ tsp garlic powder
  • Salt and black pepper to taste

Step-by-Step Baking Fun

1. Preheat and Prepare Your Ingredients

Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish to ensure your casserole comes out easily. In a skillet over medium heat, cook the ground beef until it’s nicely browned. Once cooked, drain the excess grease to keep the dish light. Season the beef with salt, pepper, and garlic powder for extra flavor.

2. Mix the Main Ingredients

In a large mixing bowl, combine uncooked rice, the packet of French onion soup mix, and beef broth. Give it a good stir to mix everything well. Now, it’s time to add in the cooked ground beef and sour cream, blending it all together. The creamy sour cream adds a delightful richness. Once combined, transfer this delicious mixture to your prepared baking dish. Spread it out evenly so every bite is flavorful!

3. Bake to Perfection

Top your casserole with shredded cheese for that irresistible bubbly goodness. Cover the dish with aluminum foil and bake it in the oven for 40 minutes. Next, remove the foil and bake for an additional 10-15 minutes until the cheese is bubbly and golden. For a final touch, add the French-fried onions on top and bake for another 5 minutes until golden brown. Once baked, let it cool slightly before serving, and enjoy the aromatic goodness.

How to Serve French Onion Ground Beef and Rice Casserole in Style

How to Store (If Any Survive!)

If you find yourself with leftovers (though I doubt it), storing them is easy! Let the casserole cool completely after baking. Cover the dish with plastic wrap or transfer servings to airtight containers. You can keep it in the refrigerator for up to 3 days. For longer storage, freeze portions for up to 2 months. Just pop it in the oven to reheat, and it’ll taste almost as good as new!

Fun Twists and Variations

Feel free to make this recipe your own! You can add steamed vegetables like broccoli or green beans for a colorful twist. Swap the beef for ground turkey or chicken to lighten it up. Want a spicy kick? Add a bit of chili powder or diced jalapeños. Drizzle a bit of barbecue sauce over the top before baking for that sweet and tangy flavor. The possibilities are endless!
