Soup Ingredients
- 4 large onions, thinly sliced
- 4 tablespoons butter
- 1 tablespoon olive oil
- 1 teaspoon salt
- 1 teaspoon sugar
- 8 cups beef broth
- 1/2 cup dry white wine
- 1 teaspoon thyme
- 1 bay leaf
Topping Ingredients
- 1 baguette, sliced
- 2 cups grated Gruyere cheese
Instructions
- Heat Butter and Oil: Melt the butter and olive oil in a large pot over medium heat to prepare the base for caramelizing the onions.
- Caramelize Onions: Add the thinly sliced onions, salt, and sugar to the pot. Cook them slowly until they are deeply caramelized and soft, which takes about 25 minutes. This step develops the rich flavor essential to the soup.
- Add Wine and Herbs: Stir in the dry white wine, thyme, and bay leaf. Let the mixture simmer gently for 10 minutes to meld the flavors.
- Simmer with Broth: Pour in the beef broth and bring the soup to a boil. Then reduce the heat to low and let it simmer for 30 minutes to fully develop the taste.
- Preheat Oven: While the soup simmers, preheat your oven to 400°F (200°C) to prepare for toasting the bread and melting the cheese.
- Toast Baguette: Slice the baguette and toast the pieces in the oven until golden brown, creating a perfect base for the cheesy topping.
- Assemble Bowls: Ladle the hot soup into oven-safe bowls, place the toasted baguette slices on top of the soup, and generously sprinkle grated Gruyere cheese over the bread.
- Bake to Melt Cheese: Place the bowls in the oven and bake for about 10 minutes, or until the cheese is melted, bubbly, and lightly browned, forming a delicious crust.
Notes
- Use a heavy-bottomed pot for even heat distribution during caramelization.
- Caramelizing onions slowly over medium heat is key to developing the soup’s rich flavor; do not rush this step with high heat.
- Dry white wine adds acidity that balances the richness but can be omitted or replaced with more broth if preferred.
- Gruyere cheese can be substituted with Emmental or Swiss cheese for a similar flavor.
- Serve immediately after baking to enjoy the cheese melted and gooey.
- For a vegetarian version, substitute beef broth with mushroom or vegetable broth.
