Description
A classic French onion soup topped with Gruyère cheese and toasted baguette croutons, perfect for a comforting meal.
Ingredients
Scale
- 2 tablespoons unsalted butter
- 2 tablespoons olive oil
- 4 large white onions, thinly sliced
- 2 cloves garlic, minced
- 1 teaspoon sugar
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 1 tablespoon all-purpose flour
- 8 cups beef broth
- 1 cup dry white wine
- 1 tablespoon fresh thyme leaves (or 1 teaspoon dried thyme)
- 1 bay leaf
- 1 baguette, sliced into 1-inch pieces
- 2 cups shredded Gruyère cheese
Instructions
- In a large pot, melt the butter and olive oil over medium heat. Add the sliced onions and cook, stirring frequently, for about 30 minutes until they are caramelized and golden brown.
- Stir in the minced garlic, sugar, salt, and pepper. Cook for an additional 2 minutes.
- Sprinkle the flour over the onions and stir well to combine. Cook for 1-2 minutes to eliminate the raw flour taste.
- Gradually add the beef broth and white wine, stirring constantly. Add the thyme and bay leaf. Bring the mixture to a simmer and cook for 30 minutes, allowing the flavors to meld.
- While the soup simmers, preheat your oven to 400°F. Arrange the baguette slices on a baking sheet and toast in the oven for about 5-7 minutes until golden.
- Remove the bay leaf from the soup. Ladle the soup into oven-safe bowls, top each with a few toasted baguette slices, and sprinkle generously with Gruyère cheese.
- Place the bowls on a baking sheet and bake in the oven for 10-15 minutes, or until the cheese is bubbly and golden brown.
Notes
- For a richer flavor, use a combination of beef and chicken broth.
- Add a splash of sherry or brandy to the soup for an extra depth of flavor.
