Step‑by‑Step Instructions for Hearty French Onion Ground Beef and Rice Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). This temperature is key for baking the casserole evenly. While the oven is warming up, you can prepare the other ingredients, ensuring that everything is ready to create your flavorful French Onion Ground Beef and Rice dish.
Step 2: Cook the Ground Beef
In a large skillet over medium heat, add your ground beef and cook until it’s well browned, about 6-8 minutes. Use a wooden spoon to break it apart, allowing it to cook evenly and nicely. Once browned, be sure to drain any excess fat, as this will keep your casserole from being overly greasy.
Step 3: Combine Rice and Soup
Next, in the skillet with your cooked ground beef, mix in the cooked rice and French onion soup. Stir the mixture until everything is well combined and heated through, which should take about 2-3 minutes. The rice will absorb the savory flavors, creating a delicious foundation for your French Onion Ground Beef and Rice casserole.
Step 4: Transfer to Baking Dish
Carefully transfer the beef and rice mixture into a greased baking dish, spreading it evenly across the bottom. Make sure the mixture is level to ensure even cooking. This form will provide a solid base for the cheese topping and make serving easier once baked.
Step 5: Add Cheese Topping
Now it’s time to crown your casserole! Generously sprinkle your choice of cheese over the beef and rice mixture. Depending on your preference, you can mix different cheeses for added flavor, or just stick to one. Aim for a nice, even layer to create a golden and bubbly top as it bakes.
Step 6: Bake and Enjoy
Place the baking dish in the preheated oven and bake for 25-30 minutes. Keep an eye on it until the cheese is melted, bubbly, and slightly golden on top. The aroma will fill your kitchen, hinting at the comforting flavors of your French Onion Ground Beef and Rice casserole that awaits.
Step 7: Cool and Serve
Once baked to perfection, carefully remove the casserole from the oven and let it cool for about 5 minutes. This resting time helps it set a little, making it easier to serve. Prepare to enjoy a warm helping of this hearty dish that’s sure to delight your family and friends!

Make Ahead Options
These Hearty French Onion Ground Beef and Rice Casserole is perfect for meal prep enthusiasts looking to save time! You can prepare the casserole up to 24 hours in advance by assembling all the ingredients except the cheese and refrigerating the unbaked dish. To maintain the best flavors and texture, cover the casserole tightly with plastic wrap. When you’re ready to enjoy, simply sprinkle the cheese on top and bake it straight from the fridge, adding an extra 5-10 minutes to the baking time.

French Onion Ground Beef and Rice Casserole Recipe FAQs

What should I do if my casserole turns out dry?
