What You’ll Need
This recipe calls for simple, readily available ingredients. You likely already have most of them in your pantry! Here’s what you’ll need:
- 1 pound (450g) lean ground beef: The foundation of our flavor-packed casserole. Lean ground beef ensures a healthier, less greasy dish.
- ½ to 1 tsp garlic salt, or to taste: This adds a subtle yet essential savory punch. Adjust the amount according to your preference.
- 2 cans (10.5 oz each) beef consomme: Provides a rich, savory base for the casserole, enhancing the overall flavor profile.
- 2 cans (10.5 oz each) French onion soup: The star of the show! This delivers that signature sweet and savory French onion flavor.
- 180ml (¾ cup) water: Helps to create a creamy, flavorful sauce for the rice and ground beef.
- 2 cups long grain white rice, uncooked: The perfect base that soaks up all that delicious French onion and beefy goodness.
- 170g (¾ cup) butter, sliced (1 ½ sticks): Adds richness and helps create a creamy, comforting texture. Don’t be afraid of the butter – it’s worth it!
Step-by-Step Instructions
Let’s get cooking! This recipe is surprisingly simple, but the results are unbelievably delicious.
- Preheat your oven to 375°F (190°C). This ensures the casserole cooks evenly and perfectly.
- Brown the ground beef: In a large oven-safe skillet or casserole dish, brown the ground beef over medium-high heat, breaking it up with a spoon as it cooks. Tip: Drain off any excess grease once the beef is browned. This helps keep the casserole from being too greasy.
- Season the beef: Once the beef is browned, sprinkle it with ½ to 1 teaspoon of garlic salt (or to taste). Stir well to combine. Tip: Taste the beef and adjust the seasoning as needed. You can add a pinch of black pepper or other herbs for extra depth of flavor.
- Add the liquids: Pour in the beef consommé, French onion soup, and water. Stir gently to combine, ensuring the beef is well coated in the flavorful liquid.
- Stir in the rice: Add the uncooked long grain white rice to the skillet. Stir gently to distribute the rice evenly throughout the liquid.
- Dot with butter: Arrange the sliced butter evenly over the top of the rice and liquid mixture. Tip: This helps create a creamy, rich sauce as the casserole bakes.
- Bake: Cover the skillet or casserole dish tightly with a lid or aluminum foil. Bake for 30-35 minutes, or until the rice is cooked through and the liquid is absorbed. Tip: Check the rice for doneness after 30 minutes. If it’s still too firm, continue baking for a few more minutes, checking every 2-3 minutes.
- Rest and serve: Once cooked, remove the casserole from the oven and let it rest for 5-10 minutes before serving. This allows the flavors to meld and the casserole to set slightly. Serve warm and enjoy!
Tips for Success
Here are a few tips to guarantee a perfect French Onion Ground Beef and Rice Casserole every time:
Don’t overcook the rice: Overcooked rice can become mushy. Start checking for doneness at the 30-minute mark and adjust cooking time as needed. The rice should be tender but still have a slight bite to it.
Use good quality ingredients: The better the ingredients, the better the casserole will taste. Look for flavorful beef consommé and a French onion soup that you enjoy.
Adjust seasonings to your taste: Don’t be afraid to experiment with different herbs and spices. A pinch of thyme, rosemary, or even a dash of Worcestershire sauce can add a delicious twist.
Let the casserole rest: Allowing the casserole to rest for a few minutes before serving allows the flavors to meld together and creates a more cohesive, flavorful dish.
Variations to Try
Feeling adventurous? Try these variations to personalize your French Onion Ground Beef and Rice Casserole:
Add vegetables: Sautéed mushrooms, diced carrots, or chopped bell peppers would be delicious additions, adding extra texture and nutrients.
Spice it up: A pinch of red pepper flakes or a dash of your favorite hot sauce will add a kick.
Make it cheesy: Sprinkle shredded cheddar, Gruyère, or even some Parmesan cheese on top during the last 10 minutes of baking for an extra cheesy layer of deliciousness.
Vegetarian option: Substitute the ground beef with 1 cup of cooked lentils or crumbled vegetarian ground beef for a hearty vegetarian version.

Storing and Reheating
Leftovers are just as delicious! Store your French Onion Ground Beef and Rice Casserole in an airtight container in the refrigerator for up to 3 days. To reheat, simply microwave individual portions until warmed through, or reheat gently in a skillet over low heat, adding a splash of water or broth if needed to prevent it from drying out.
Freezing is also an option! Allow the casserole to cool completely before transferring it to a freezer-safe container. It will keep for up to 3 months in the freezer. Thaw overnight in the refrigerator before reheating.
