- Long grain white rice: The perfect base, providing fluffy texture that absorbs the soup’s flavor beautifully.
- Condensed French onion soup: This is the star ingredient, delivering that iconic savory onion and beef broth combo.
- Beef broth: Adds depth and a richer meaty undertone; you can swap with chicken or vegetable broth if you prefer.
- Butter: Sliced on top to melt and create a velvety finish with a hint of richness.
- Sliced mushrooms (optional): Introduce an earthy, meaty texture and amplify the depth of flavor.
- Garlic powder: Enhances the overall aroma and adds a subtle hint of garlic without overpowering.
- Onion powder: Boosts the onion flavor, complementing the soup for an extra punch.
- Salt and black pepper: Essential for seasoning to taste, balancing all the flavors perfectly.
- Fresh parsley (optional): Gives a fresh, vibrant color and a mild herbal note as a finishing touch.
How to Make French Onion Soup Rice Recipe
Step 1: Prepare Your Oven and Baking Dish
Start by preheating your oven to 375°F (190°C). Lightly grease a 9×9-inch (or similar size) baking dish to prevent sticking and ensure easy cleanup. This step sets the stage for perfectly cooked rice that won’t cling to the pan.
Step 2: Combine Ingredients in the Dish
In your greased baking dish, add the uncooked rice, the can of condensed French onion soup, and the beef broth. Sprinkle in the garlic powder and onion powder for extra flavor, then toss in the sliced mushrooms if you’re using them. Give everything a good stir to mix the ingredients evenly so each grain of rice gets coated and ready to soak up every bit of flavor.
Step 3: Add Butter and Cover
Now take your sliced butter and arrange it evenly over the rice mixture’s surface. This step is key because as the butter melts during baking, it creates a rich, creamy surface that enhances every bite. Next, cover the dish tightly with foil to trap steam, which helps the rice cook evenly and absorb all the delicious broth.
Step 4: Bake and Finish
Pop the dish into your preheated oven and bake covered for 30 minutes. After that, remove the foil and continue baking for another 25 to 30 minutes, or until the rice is tender and has mostly absorbed the liquid. Fluff the rice gently with a fork to separate the grains. Your French Onion Soup Rice Recipe is now ready for the finishing touches and serving!
How to Serve French Onion Soup Rice Recipe

Garnishes
A sprinkle of freshly chopped parsley adds a welcoming burst of green that brightens the dish visually and adds a subtle herbal freshness that beautifully offsets the savory depth of the rice. For an indulgent twist, a light dusting of shredded Gruyère or mozzarella cheese melted on top in the last 10 minutes of baking can turn this into a decadent treat.
Side Dishes
This rice pairs wonderfully as an accompaniment to grilled meats like steak or chicken, where it absorbs any fantastic pan juices. Roasted vegetables or a crisp green salad provide a fresh and crunchy contrast that balances out the creamy richness of the rice.
Creative Ways to Present
Serve this rice in individual ramekins or small bowls for a charming presentation that feels restaurant-worthy. You can even hollow out mini bell peppers or tomatoes to serve the rice inside for a colorful and fun twist that guests will love. A drizzle of extra broth or a dollop of sour cream on top can add an extra dimension of flavor and moisture.
Make Ahead and Storage
Storing Leftovers
If you have leftovers (and that might be tough!), transfer them to an airtight container and refrigerate for up to 3 days. The rice will thicken as it cools, so reheating gently with a splash of broth can help restore its creamy texture.
Freezing
This French Onion Soup Rice Recipe freezes well, making it perfect for meal prep. Place cooled rice in freezer-safe containers or bags, leave some space for expansion, and freeze for up to 2 months. Thaw overnight in the fridge before reheating.
Reheating
Rewarm the rice in a saucepan over low heat or in the microwave with a little added broth or water to loosen it up. Stir occasionally until heated through and creamy again. Avoid overheating to keep the texture tender and tasty.
FAQs
Can I use brown rice in this French Onion Soup Rice Recipe?
Brown rice requires a longer cooking time and more liquid, so it’s not ideal for this recipe as written. However, you could partially pre-cook the brown rice before following the recipe steps to ensure it cooks thoroughly.
Is this recipe vegetarian-friendly?
Yes! By swapping the beef broth for vegetable broth and using vegetarian French onion soup or a homemade version, you can easily make this dish vegetarian while keeping the same comforting flavors.
Can I add cheese to the French Onion Soup Rice Recipe?
Absolutely, cheese like Gruyère or mozzarella is a fantastic addition. Sprinkle it on in the last 10 minutes of baking to get a melty, golden crust that makes the dish even more indulgent.
What can I substitute for mushrooms if I don’t like them?
If mushrooms aren’t your thing, you can omit them or replace them with diced bell peppers, caramelized onions, or even cooked spinach for a different vegetable boost without changing the flavor too much.
How do I make sure the rice doesn’t stick to the baking dish?
Greasing the baking dish lightly at the beginning is crucial. Also, avoid baking uncovered until the very end, as the foil trap steam and helps cook the rice evenly, preventing sticking and burning on the edges.
