Step-by-Step Instructions
Preheat the Oven
Start by preheating your oven to 350°F (175°C). This step helps the casserole cook evenly.
Caramelize the Onions
In a large skillet, heat 2 tablespoons of olive oil over medium heat. Add 1 large onion, thinly sliced. Cook for 10-12 minutes. Stir the onions often. You want them golden brown and sweet. This process brings out their natural sugars.
Cook the Ground Beef
Once the onions are done, push them to one side of the skillet. Add 1 pound of ground beef to the empty side. Cook the beef until it is fully browned. Break it apart with a spatula as it cooks. Season it with 1 teaspoon of garlic powder, 1 teaspoon of dried thyme, salt, and pepper to taste. Mix the beef with the onions when it’s cooked.
Combine All Ingredients
In a large mixing bowl, combine the cooked rice, beef, and onion mixture. Add 2 cups of beef broth and 1 cup of French onion dip. Stir everything together until well mixed. This helps all the flavors blend nicely.
Prepare the Casserole Dish
Transfer the mixture into a greased 9×13 inch casserole dish. Spread it out evenly. This ensures that every part cooks the same way.
Baking Instructions
Sprinkle 1 cup of shredded Swiss cheese on top. Cover the dish with aluminum foil. Bake it in the preheated oven for 25 minutes. Then, remove the foil and bake for another 10-15 minutes. This helps the cheese melt and bubble. When done, let it rest for 5 minutes before serving. Garnish with fresh parsley if you like.
Tips & Tricks
Best Practices for Caramelizing Onions
To get sweet, golden onions, you need patience. Start with medium heat. Use a large skillet for even cooking. Add olive oil and let it warm. Stir the onions often for even browning. It takes about 10 to 12 minutes. Watch for that deep, rich color. If they stick, lower the heat slightly. You can sprinkle a pinch of salt to help draw out moisture. This extra step enhances their flavor.
Cooking Tips for Perfect Beef
For juicy beef, use ground beef with some fat. It adds flavor and keeps it moist. Cook in the same skillet after the onions. This helps blend flavors. Break the beef apart with a spatula for even cooking. Season with garlic powder, thyme, salt, and pepper. Make sure it’s fully browned. This means no pink spots remain.
How to Avoid a Soggy Casserole
To keep your casserole from being soggy, use cooked rice that’s not overcooked. If possible, use day-old rice. This rice is firmer and absorbs less moisture. When mixing ingredients, don’t add too much broth. You want a creamy texture but not a soup. Spread the mixture evenly in the casserole dish. Cover with foil for the first part of baking. This traps steam for cooking, but remove it later to crisp the cheese.
Pro Tips
- Use Fresh Ingredients: Always opt for fresh onions and beef for the best flavor. Fresh ingredients can elevate the dish significantly.
- Layering Cheese: For an extra cheesy top, consider using a mix of cheeses like mozzarella and Gruyère along with the Swiss cheese.
- Resting Time: Allowing the casserole to rest after baking helps the flavors meld together and makes serving easier.
- Customize Your Rice: Feel free to use flavored rice or add sautéed vegetables to the rice mixture for additional texture and taste.

Variations
Alternative Proteins
If you want to switch up the protein in this dish, you have options. Ground turkey or chicken works great. You can also use a plant-based meat substitute if you prefer. These proteins still give that tasty flavor we love in this casserole. Just remember to adjust cooking times based on what you choose.
Vegetarian Option
To make a vegetarian version, skip the meat. Use lentils or mushrooms for hearty texture. Cooked quinoa can also add protein and flavor. Use vegetable broth instead of beef broth. Combine with the rice, onion, and dip, and you’ll have a delicious dish without meat.
Cheese Substitutes
If you want to change the cheese, you have some choices. Gruyère or mozzarella works well in place of Swiss cheese. You can try a vegan cheese for a dairy-free option. Just make sure whatever cheese you pick melts well. This will keep your casserole creamy and rich.
