Step-by-Step Instructions
Preparing the Casserole
1. Preheating the oven: Start by preheating your oven to 350°F (175°C). This step is key for cooking the casserole evenly.
2. Cooking onions and garlic: In a large skillet, heat 2 tablespoons of olive oil over medium heat. Add 2 large onions, thinly sliced. Cook them for about 15 to 20 minutes until they turn golden brown. Stir them often to avoid burning. After the onions are caramelized, add 2 cloves of minced garlic. Sauté for another 2 minutes until the garlic smells great. Remove the skillet from heat.
3. Browning the beef: In the same skillet, add 1 pound of ground beef. Cook it over medium-high heat until it is browned. Break the beef up with a spatula as it cooks. Once browned, drain any excess fat to keep it lean and tasty.
Combining and Baking
1. Mixing the ingredients: In a large mixing bowl, combine the cooked beef, caramelized onions, and garlic. Add 1 cup of uncooked long-grain rice, 2 cups of beef broth, 1 tablespoon of Worcestershire sauce, 1 teaspoon of dried thyme, and salt and pepper to taste. Mix everything well until it is evenly combined.
2. Assembling the casserole: Pour the mixture into a greased 9×13 inch baking dish. Spread it out evenly to ensure even cooking.
3. Baking time and cheese addition: Cover the dish with aluminum foil and bake in the preheated oven for 30 minutes. After 30 minutes, remove the foil. Sprinkle 1 cup of shredded Swiss cheese evenly over the top. Return the dish to the oven and bake uncovered for another 10 to 15 minutes until the cheese is melted and bubbly. Enjoy the aroma that fills your kitchen!
Tips & Tricks
Perfecting the Dish
To make the best French onion beef and rice casserole, start with the onions. Caramelizing them is key.
- Heat olive oil over medium heat.
- Add sliced onions and stir often.
- Cook for about 15-20 minutes until they turn golden brown.
- Add minced garlic and sauté for 2 more minutes.
This brings out their natural sweetness.
Next, browning the beef can be tricky.
- Use medium-high heat in the same skillet.
- Break the meat apart as it cooks.
- Cook until browned, then drain any fat.
This step adds depth to the dish.
Enhancing Flavor
Using homemade beef broth can make a big difference. Store-bought broth often lacks the rich taste you want. If you can, make your own.
- Simmer beef bones with water, veggies, and herbs.
- Strain and store it for later use.
This adds a fresh, deep flavor.
Herbs and spices also boost the taste.
- Add dried thyme for a warm note.
- Don’t forget to season with salt and pepper.
You can also try other herbs. Fresh parsley adds brightness when you garnish the dish.
These steps will ensure your casserole shines with flavor!
Pro Tips
- Tip Title: Use Sweet Onions: For a richer flavor, opt for sweet onions like Vidalia or Walla Walla when caramelizing. Their natural sugars will enhance the dish’s sweetness.
- Tip Title: Beef Broth Variations: Experiment with low-sodium beef broth for a healthier option, or use homemade broth to elevate the overall taste of your casserole.
- Tip Title: Cheese Choices: While Swiss cheese is classic, feel free to mix in Gruyère or a sharp cheddar for added flavor and a delightful cheese pull.
- Tip Title: Leftovers Storage: Store any leftovers in an airtight container in the fridge for up to 3 days. Reheat in the oven for best results, ensuring the cheese stays melty.

Variations
Ingredient Swaps
Alternative meats
You can switch out the ground beef for other meats. Ground turkey or chicken works well. You can also try ground lamb for a richer flavor. Each meat gives the dish a unique taste.
Different cheese options
Swiss cheese is great, but feel free to mix it up. Gruyère cheese offers a nutty flavor. You can use cheddar for a sharper taste. If you want a creamier texture, try mozzarella. Each cheese choice adds its own twist.
Dietary Modifications
Gluten-free adjustments
To make this dish gluten-free, use gluten-free beef broth. You can also swap the rice for quinoa or cauliflower rice. Both options taste good and keep the dish gluten-free.
Vegetarian version ideas
For a vegetarian option, replace the beef with lentils or mushrooms. Use vegetable broth instead of beef broth. You can also add more veggies, like bell peppers or carrots, for extra flavor. This way, you enjoy a hearty meal without meat.
Storage Info
Cooling and Storing
To cool your casserole properly, let it sit at room temperature for about 30 minutes. This helps prevent moisture buildup. After cooling, transfer it to an airtight container. Glass or plastic containers work well. Make sure they are food-safe and can handle heat.
Reheating Casserole
For reheating, the best method is using the oven. Preheat it to 350°F (175°C). Place the casserole in an oven-safe dish. Cover it with foil to keep it moist. Bake for about 20-25 minutes.
You can also use the microwave. Use a microwave-safe dish and cover it. Heat in short bursts, stirring in between. This helps keep the rice from drying out. To keep your casserole moist, add a splash of beef broth or water before reheating.
