French Onion Ground Beef and Rice Casserole Ingredients
• Get ready to create a comforting masterpiece!
For the Casserole
- Ground Beef – Provides protein and richness; lean beef works well for a lighter option.

- Uncooked Rice – Acts as the main body; long-grain white rice offers the best texture for this dish.

Step‑by‑Step Instructions for French Onion Ground Beef and Rice Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C). This ensures that the French Onion Ground Beef and Rice Casserole bakes evenly and thoroughly. While the oven heats up, gather all your ingredients and equipment, like a large skillet and a 9×13-inch baking dish. Having everything ready will make your cooking process smooth and enjoyable.
Step 2: Brown the Ground Beef
In a skillet over medium heat, add the ground beef and cook until it’s browned and no longer pink, which should take about 5-7 minutes. As the beef cooks, use a spatula to break it into small pieces. Once cooked, drain any excess fat, but leave about a tablespoon in the skillet to enhance flavor.
Step 3: Caramelize the Onions
Reduce the heat to medium-low and add butter along with the sliced onions to the skillet, stirring well. Allow the onions to caramelize for 10-15 minutes, stirring occasionally, until they turn a lovely golden brown. This sweet, aromatic stage enhances the depth of flavor in your French Onion Ground Beef and Rice Casserole, filling your kitchen with a delicious fragrance.
Step 4: Combine the Ingredients
Now, stir in the uncooked rice, cream of mushroom soup, and beef broth into the caramelized onions and browned beef. Season with salt and pepper to taste. Mix everything thoroughly until the rice is evenly coated with the creamy sauce. This mixture will create the hearty filling for your casserole, combining flavors beautifully.
Step 5: Transfer to Baking Dish
Carefully transfer the mixture to a greased 9×13-inch baking dish, spreading it out evenly. To lock in moisture and steam the rice perfectly, cover the dish tightly with aluminum foil. Place the casserole in your preheated oven and bake for 25 minutes, allowing the rice to cook and absorb the rich flavors.
Step 6: Add Cheese and Finish Baking
After 25 minutes, remove the foil and sprinkle a generous amount of shredded cheddar cheese on top of the casserole. Return the dish to the oven and bake uncovered for an additional 10 minutes. This step will melt the cheese and create a bubbly, golden layer that adds a delightful texture to your French Onion Ground Beef and Rice Casserole.
Step 7: Rest Before Serving
Once the cheese is melted and bubbly, take the casserole out of the oven and let it rest for about 5 minutes. This resting period allows the flavors to meld further and makes serving easier. Once ready, scoop out portions and enjoy this heartwarming dish with your family, savoring every flavorful bite!
