Step‑by‑Step Instructions for French Onion Ground Beef and Rice Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). This ensures the French Onion Ground Beef and Rice Casserole will bake evenly, resulting in a bubbly and golden cheese layer on top. Set a timer for later, as this step prepares your oven for the deliciousness to come.
Step 2: Brown the Ground Beef
In a large skillet over medium heat, add the ground beef and cook until it’s browned, typically about 5-7 minutes. As it cooks, break up any large clumps with a spatula. Once browned, drain any excess fat from the skillet, retaining the beef juices as a flavorful base for your casserole.
Step 3: Caramelize the Onions
In the same skillet, add sliced onions to the remaining juices. Sauté them on medium heat for about 10-15 minutes, stirring frequently until they become deeply caramelized and golden brown. This step is crucial for developing the rich, sweet flavor that will elevate your French Onion Ground Beef and Rice Casserole.
Step 4: Combine Ingredients
In a large mixing bowl, combine the cooked rice, browned ground beef, caramelized onions, beef broth, Worcestershire sauce, thyme, salt, and pepper. Gently mix everything together until well incorporated, ensuring that every bite of the casserole will be packed with flavor.
Step 5: Transfer to Casserole Dish
Next, lightly grease a 9×13-inch casserole dish with cooking spray or oil. Pour the beef and rice mixture into the dish, spreading it out evenly. Ensure the mixture is evenly distributed to achieve uniform cooking and texture throughout your French Onion Ground Beef and Rice Casserole.
Step 6: Add Cheese Topping
Generously sprinkle shredded cheddar cheese evenly over the top of the casserole. The cheese will melt and create a beautifully gooey layer, adding that comforting touch that is essential for any good casserole. Don’t hold back—this layer is vital for delicious flavor!
Step 7: Bake the Casserole
Place the casserole in the preheated oven and bake for 30 minutes. Keep an eye on it; you’ll know it’s done when the cheese is bubbly and has turned a lovely golden brown. The warm aroma wafting through your kitchen will be a sure sign that dinner is nearly ready.
Step 8: Serve and Enjoy
Once the French Onion Ground Beef and Rice Casserole is out of the oven, let it rest for a few minutes before serving. This will allow the flavors to meld together beautifully. Then scoop out generous portions and enjoy a delightful meal that’s sure to bring comfort to your table!

Make Ahead Options
These French Onion Ground Beef and Rice Casserole is perfect for meal prep enthusiasts! You can assemble the entire casserole up to 24 hours in advance by following the initial steps and then covering it tightly with plastic wrap or aluminum foil.

For even better results, you can caramelize the onions and brown the beef earlier in the week, storing them in the refrigerator for up to 3 days before use. When you’re ready to bake, simply uncover and pop it in the oven, adding an extra few minutes to the baking time if it’s chilled. This way, you’ll have a comforting meal ready with minimal effort, perfect for those busy weeknights!
