Recipe Information
Ingredients
- 4 tablespoons unsalted butter
- 4 large yellow onions, thinly sliced
- 2 cloves garlic, minced
- 1 teaspoon brown sugar
- 2 tablespoons all-purpose flour
- 5 cups beef broth
- 1 cup dry white wine
- 1 piece bay leaf
- 1 teaspoon fresh thyme
- 1 teaspoon salt
- 1 teaspoon black pepper
- 6 pieces baguette slices, toasted
- 2 cups Gruyère cheese, shredded
- 0.5 cup Parmesan cheese, grated
Instructions
Melt the butter in a large pot over medium heat. Add the sliced onions and cook for 10 minutes, stirring occasionally.
Add the minced garlic and brown sugar to the pot. Reduce the heat to low and cook the onions for 25-30 minutes, stirring frequently, until caramelized and golden brown.
Sprinkle the flour over the onions and stir well to coat. Cook for another 1-2 minutes to eliminate the raw flour taste.
Gradually add the beef broth and white wine, stirring constantly to avoid lumps. Bring the mixture to a simmer.
Add the bay leaf, fresh thyme, salt, and black pepper. Simmer the soup for 20 minutes, stirring occasionally. Remove the bay leaf and adjust seasoning if necessary.
Preheat the oven to broil. Ladle the soup into oven-safe bowls and top each with a toasted baguette slice.
Sprinkle a generous amount of Gruyère and Parmesan cheese over the bread. Place the bowls on a baking sheet and broil in the oven for 2-3 minutes, or until the cheese is melted and bubbly.
Carefully remove the bowls from the oven and let them cool slightly before serving. Enjoy your cheesy onion soup!
