Recipe Information
Ingredients
- 3 tablespoons unsalted butter
- 2 tablespoons olive oil
- 6 large yellow onions, thinly sliced
- 1 teaspoon granulated sugar
- 2 tablespoons all-purpose flour
- 1 cup dry white wine
- 8 cups beef stock or broth
- 2 fresh thyme sprigs
- 1 bay leaf
- 1 baguette, sliced
- 2 cups grated Gruyère cheese
- to taste salt
- to taste black pepper
Instructions
In a large heavy-bottomed pot or Dutch oven, melt the butter with the olive oil over medium heat.
Add the thinly sliced onions and a pinch of salt. Cook, stirring occasionally, for 15-20 minutes until the onions become soft and translucent.
Sprinkle the granulated sugar over the onions and stir. Lower the heat to medium-low and continue to cook, stirring frequently, for an additional 30-40 minutes until the onions are deeply caramelized and golden brown without burning.
Stir in the flour and cook for 1-2 minutes, allowing it to absorb any liquid and coat the onions.
Slowly add the dry white wine while stirring to deglaze the pot, scraping up any browned bits from the bottom.
Pour in the beef stock and add the fresh thyme sprigs and bay leaf. Bring the mixture to a boil, then reduce the heat to low and simmer for 30 minutes. Season with salt and pepper to taste.
While the soup simmers, preheat the oven to 400°F (200°C). Arrange the baguette slices on a baking sheet and toast them in the oven for 10-12 minutes, flipping halfway through, until lightly golden and crisp.
Turn the oven to broil. Ladle the hot soup into oven-safe bowls. Place a toasted baguette slice on top of each bowl and sprinkle generously with grated Gruyère cheese.
Place the bowls on a baking sheet and broil for 2-3 minutes, or until the cheese is melted, bubbly, and lightly browned. Watch carefully to avoid burning.
Carefully remove the bowls from the oven and let cool for a minute before serving. Enjoy your authentic French Onion Soup!
