Ingredients
4 large yellow onions, thinly sliced
2 tablespoons unsalted butter
2 tablespoons olive oil
3 garlic cloves, minced
1 teaspoon salt
1/2 teaspoon black pepper
1 teaspoon granulated sugar
1 tablespoon all-purpose flour
1/2 cup dry white wine or dry sherry
6 cups beef broth
1 cup chicken broth
1 teaspoon Worcestershire sauce
2 fresh thyme sprigs
1 bay leaf
1 French baguette, sliced
2 tablespoons olive oil or melted butter for bread
2 cups Gruyère cheese, grated
1/2 cup mozzarella cheese, shredded
1/4 cup Parmesan cheese, grated
1 teaspoon balsamic vinegar (optional)
Fresh thyme or parsley for garnish
Instructions
1. Heat butter and olive oil in a large Dutch oven over medium heat. Add sliced onions, salt, pepper, and sugar. Cook for 25 to 30 minutes, stirring frequently, until the onions become deeply golden and caramelized.
2. Stir in minced garlic and cook for 1 minute until fragrant. Sprinkle flour over the onions and stir well to coat evenly.
3. Pour in the white wine or sherry and scrape the bottom of the pot to release the browned bits and deepen the flavor.
4. Add beef broth, chicken broth, Worcestershire sauce, thyme, and bay leaf. Bring the soup to a simmer and cook uncovered for 20 minutes.
5. Preheat the oven to 400°F (200°C). Arrange baguette slices on a baking sheet, brush lightly with olive oil or butter, and toast until golden and crisp.
6. Remove the thyme sprigs and bay leaf from the soup. Ladle the soup into oven-safe bowls and top each with toasted bread slices.
7. Sprinkle Gruyère, mozzarella, and Parmesan cheese generously over the bread.
8. Place the bowls under the broiler for 2 to 4 minutes until the cheese is melted, bubbly, and golden brown.
9. Garnish with fresh thyme or parsley and serve immediately while hot.
Notes
Caramelize the onions slowly over medium heat for the best sweet and rich flavor. Rushing this step can lead to bitter onions instead of deep golden caramelization.
Toast the bread before adding it to the soup so it keeps its texture and does not become soggy too quickly.
Use freshly grated Gruyère cheese whenever possible because it melts more smoothly and creates the classic cheesy crust French onion soup is known for.
