Ingredients
Scale
Soup Base
- 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
- 1 baguette, sliced
- 2 cups grated Gruyere cheese
Instructions
- Sauté Onions: Melt butter and olive oil in a large pot over medium heat. Add sliced onions, salt, and sugar. Cook, stirring occasionally, until the onions become deeply caramelized and golden brown, which should take about 25 minutes.
- Deglaze and Simmer: Stir in the dry white wine, thyme, and bay leaf. Let the mixture simmer gently for 10 minutes to develop flavor.
- Add Broth and Simmer: Pour in the beef broth and bring the soup to a boil. Once boiling, reduce heat to low and simmer uncovered for 30 minutes, allowing flavors to meld.
- Prepare Baguette: While the soup simmers, preheat your oven to 400°F (200°C). Place baguette slices on a baking sheet and toast them in the oven until they turn golden brown, about 5-7 minutes.
- Assemble Soup Bowls: Ladle the hot onion soup into oven-safe bowls. Top each bowl with a few toasted baguette slices, then generously sprinkle grated Gruyere cheese over the bread to cover.
- Bake with Cheese: Place the bowls on a baking tray and bake in the preheated oven for about 10 minutes, or until the cheese is fully melted, bubbly, and slightly golden on top.
- Serve: Carefully remove the bowls from the oven and serve the French Onion Soup immediately to enjoy the perfect balance of savory broth, sweet caramelized onions, crunchy bread, and melted cheese.
Notes
- Use dry white wine for deglazing to enhance depth of flavor without overpowering the soup.
- Gruyere cheese is traditional for authentic taste and excellent melting quality; you can substitute with Emmental if needed.
- Caramelizing onions is key to the soup’s rich flavor; patience is essential for best results.
- The soup bowls must be oven-safe to bake the cheese topping safely in the oven.
