How to Make French Onion Ground Beef and Rice Casserole Recipe
Step 1: Caramelize the Onions
Melt the butter in a large skillet over medium-low heat, then add the sliced yellow onions. Patience is key here because slowly cooking the onions for about 20 to 25 minutes until they’re deeply golden and caramelized is what gives the casserole its rich, sweet backbone. Stir occasionally to prevent burning and ensure even color development.
Step 2: Brown the Ground Beef and Sauté Garlic
While the onions work their magic, brown your ground beef in another skillet over medium heat. Once the beef is cooked through, drain the excess fat to keep the dish from feeling greasy. Toss in the minced garlic and cook for just another minute—this way the garlic’s flavor stays fresh and vibrant. Season the beef with salt and black pepper to build the savory foundation of the casserole.
Step 3: Combine All Ingredients
In a large bowl, mix together the caramelized onions, ground beef mixture, uncooked rice, canned French onion soup, beef broth, and sour cream. This step is where the magic happens, transforming simple ingredients into a luscious, creamy filling that promises each serving is bursting with flavor and texture.
Step 4: Prepare for Baking
Grease a 9×13-inch baking dish to ensure nothing sticks and pour your combined mixture inside. Spread it evenly, then cover the dish tightly with foil. Covering it helps cook the rice through steam without drying out the casserole.
Step 5: Bake the Casserole
Place the dish in a preheated oven at 350°F (175°C) and bake for 50 to 55 minutes. During this time, the rice soaks up all the flavorful broth, turning soft and fluffy while the ingredients meld together into a comforting harmony.
Step 6: Add Cheese and Broil
Remove the foil and sprinkle a generous layer of shredded mozzarella and Gruyère cheese over the top. Return the casserole to the oven, uncovered, and bake for another 10 minutes. Finish by broiling for 1 to 2 minutes to achieve a golden, bubbly, irresistibly cheesy crust that is the crowning glory of this French Onion Ground Beef and Rice Casserole Recipe.
Step 7: Serve and Enjoy
Once out of the oven, let the casserole rest briefly before serving. If desired, garnish with fresh herbs like parsley or thyme to brighten the rich flavors with a pop of color and freshness.
How to Serve French Onion Ground Beef and Rice Casserole Recipe
Garnishes
Simple garnishes like chopped fresh parsley, chives, or a sprinkle of additional Gruyère cheese add a fresh and savory touch that balances the richness without overwhelming the main dish.
Side Dishes
This casserole is quite hearty on its own but pairs wonderfully with a crisp green salad dressed lightly with vinaigrette. Roasted or steamed vegetables, such as green beans or asparagus, also provide a nice, fresh contrast to the creamy, cheesy casserole experience.
Creative Ways to Present
For a rustic family-style meal, serve it straight from the baking dish with a large serving spoon. Alternatively, present individual portions scooped into small ramekins topped with a sprig of thyme for an elegant dinner party impression that will impress your guests with minimal fuss.
Make Ahead and Storage
Storing Leftovers
Store any leftover French Onion Ground Beef and Rice Casserole Recipe in an airtight container in the refrigerator. It will keep well for 3 to 4 days, allowing you to enjoy its comforting flavors even after the initial meal.
Freezing
This casserole freezes beautifully. Portion it out into freezer-safe containers or freeze the entire dish before baking. When you’re ready, thaw overnight in the fridge and follow the reheating instructions for the best texture and taste.
Reheating
Reheat leftovers in the oven at 350°F (175°C) covered with foil to prevent drying, until warmed through. A quick broil at the end will bring back that delicious golden cheese topping and ensure every bite tastes freshly baked.
FAQs
Can I use brown rice instead of white rice?
Absolutely! If you prefer brown rice, just be aware it will require a longer cooking time. You might need to pre-cook it or adjust the liquid amounts and cooking time in the casserole for optimal tenderness.
Is it necessary to use both mozzarella and Gruyère cheese?
Using both cheeses adds a great balance of meltiness and distinctive flavor. Mozzarella gives gooey stretchiness, while Gruyère provides that nutty, sophisticated taste classic to French onion dishes. You can substitute with other cheeses, but expect a different flavor.
Can I make this casserole dairy-free?
Yes! Swap butter for a dairy-free alternative, use a plant-based sour cream, and choose dairy-free cheese varieties. The casserole will still be delicious, though the flavor profile will slightly differ from the original recipe.
What’s the best way to caramelize onions faster?
Low and slow is the gold standard for caramelization to develop that rich flavor fully. If you’re short on time, adding a pinch of baking soda can speed up the browning, but be cautious as it can change texture if overused.
Can I prepare the casserole entirely in advance?
You can mix all the ingredients and prepare the dish the day before baking. Keep it covered in the fridge and bake right before serving to maintain freshness and flavor.

- 1 cup beef broth
- 1 (10.5-ounce) can French onion soup
- 1/2 cup sour cream
- 1 cup shredded mozzarella cheese
- 1 cup shredded Gruyère cheese
- 1/2 teaspoon salt
- 1/2 teaspoon black pepper
Instructions
- Caramelize Onions: Melt the butter in a large skillet over medium-low heat. Add the sliced onions and cook slowly, stirring occasionally, for about 20 to 25 minutes until they are beautifully caramelized and soft, developing a sweet and rich flavor.
- Brown Ground Beef: In a separate skillet, brown the ground beef over medium heat. Once cooked through, drain any excess fat. Stir in the minced garlic and cook for an additional minute to infuse the beef with garlic flavor. Season the mixture with salt and black pepper.
- Combine Ingredients: In a large mixing bowl, combine the browned ground beef mixture, caramelized onions, uncooked rice, French onion soup, beef broth, and sour cream. Stir everything thoroughly to ensure the rice and meat are evenly coated with the flavorful sauce.
- Prepare for Baking: Transfer the combined mixture into a greased 9×13-inch baking dish. Spread it out evenly and cover the dish tightly with aluminum foil to keep moisture in during baking.
- Bake the Casserole: Place the covered casserole in a preheated oven at 350°F (175°C). Bake for 50 to 55 minutes until the rice is tender and fully cooked through.
- Add Cheese Topping: Remove the foil. Sprinkle shredded mozzarella and Gruyère cheese evenly over the top of the casserole. Return it to the oven and bake uncovered for an additional 10 minutes. Then, switch to the broil setting and broil for 1 to 2 minutes or until the cheese is golden, bubbly, and slightly browned.
- Serve and Garnish: Serve the casserole hot, optionally garnishing with fresh herbs like chopped parsley or thyme for a burst of color and fresh aroma.
Notes
- For a richer flavor, use homemade beef broth or low-sodium broth to control saltiness.
- You can substitute Gruyère with Swiss cheese if unavailable, though Gruyère offers a nuttier flavor.
- Ensure rice is fully cooked before serving; if undercooked, cover and bake a bit longer.
- For a lighter version, use lean ground beef and reduced-fat sour cream.
- Leftovers keep well refrigerated for up to 3 days and reheat nicely in the oven or microwave.
