Ingredients for Classic French Onion Soup
Gathering the right ingredients is essential for making the best classic French onion soup. Here’s what you’ll need:
- 4 large onions, thinly sliced: The stars of the show! I love using sweet onions like Vidalia for that perfect balance of sweet and savory.
- 4 tablespoons butter: This adds richness and depth. Don’t skimp on the butter—it’s crucial for caramelizing those onions beautifully!
- 1 tablespoon olive oil: A little splash helps prevent the butter from burning and adds a nice flavor.
- 1 teaspoon sugar: This helps with the caramelization process, enhancing the sweetness of the onions.
- 8 cups beef broth: A good-quality broth is key. You want it to be rich and flavorful, so choose one you love.
- 1/2 cup dry white wine: This adds a wonderful acidity and complexity to the soup. I usually go for something like Sauvignon Blanc.
- 1 teaspoon thyme: Fresh or dried works! This herb complements the onions beautifully.
- 1 bay leaf: A must for adding depth to the flavor profile; just remember to remove it before serving!
- Salt and black pepper to taste: Essential for seasoning, so don’t forget to taste as you go!
- 8 slices of baguette: The perfect vehicle for that gooey cheese! I like to use a nice crusty baguette that can hold up under the weight of the toppings.
- 2 cups grated Gruyère cheese: This cheese is the crowning glory of the soup—melty, creamy, and oh-so-delicious. If you can’t find Gruyère, Swiss cheese is a great substitute.
With these ingredients on hand, you’re ready to create a bowl of classic French onion soup that’s both comforting and luxurious. Trust me, the aroma alone will have everyone gathering around the kitchen!
How to Prepare Classic French Onion Soup
Now that we’ve got our ingredients ready, let’s dive into the delicious process of making classic French onion soup! It’s all about patience and those beautiful caramelized onions. Trust me, this step is what makes all the difference!
- Melt the butter and olive oil: In a large pot, combine the butter and olive oil over medium heat. You want the butter to melt completely without browning—this creates the perfect base.
- Add the onions and sugar: Toss in your thinly sliced onions and sprinkle the sugar over them. Stir everything together and let it cook, stirring occasionally, for about 30 minutes. You want those onions to turn a gorgeous golden brown and develop their sweet flavor.
- Deglaze with wine: Once the onions are caramelized, pour in the dry white wine and let it simmer for about 5 minutes. This step is crucial as it lifts all those yummy bits stuck to the bottom of the pot, enhancing the flavor.
- Pour in the broth: Add the beef broth, thyme, bay leaf, salt, and pepper to the pot. Bring everything to a gentle simmer and let it bubble away for about 30 minutes. This allows all those flavors to meld beautifully.
- Prepare to broil: Preheat your oven to broil while the soup simmers. You want it nice and hot for the final cheesy topping!
- Toast the baguette: While the soup is simmering, toast your baguette slices until they’re golden brown. This adds a nice crunch to your soup!
- Assemble for broiling: Remove the bay leaf from the soup, and ladle it into oven-safe bowls. Top each bowl with a slice of toasted baguette and sprinkle generously with the grated Gruyère cheese.
- Broil the cheese: Place the bowls under the broiler for about 3-5 minutes, or until the cheese is bubbly and golden. Keep an eye on them—it happens fast!
- Serve hot: Carefully remove the bowls from the oven (they’ll be hot!) and serve your classic French onion soup immediately. Enjoy every cheesy, savory spoonful!
And there you have it! A warm, comforting bowl of classic French onion soup that’s perfect for any occasion. Just remember, the key is in the caramelization of those onions—so take your time, and let the flavors shine!

Classic French onion soup is delicious on its own, but serving it with a few sides can elevate your meal! I love pairing it with a simple green salad tossed in a light vinaigrette to balance the richness of the soup. Some crusty French bread or a warm baguette is also perfect for dipping into that cheesy goodness. For an extra treat, consider serving it with a charcuterie board featuring cured meats, cheeses, and pickles—it’s a delightful way to complement the flavors of the soup and create a cozy, inviting meal. Enjoy!
Storage & Reheating Instructions
If you’re lucky enough to have leftovers of your classic French onion soup, you’ll want to store them properly to maintain that delicious flavor and texture! Let the soup cool completely, then transfer it to an airtight container. It can be stored in the refrigerator for up to 4 days.
When it’s time to enjoy your soup again, reheat it on the stovetop over medium heat, stirring occasionally until it’s warmed through. If you’d like to revive that cheesy topping, ladle the soup into oven-safe bowls, top with toasted baguette and grated cheese, and pop it under the broiler for a few minutes until bubbly and golden. Just keep an eye on it—no one wants burnt cheese! Enjoy that cozy soup again just like the first time!
