Recipe Information
Ingredients
- 3 tablespoons unsalted butter
- 2 tablespoons olive oil
- 6 medium yellow onions
- 3 cloves garlic cloves
- 1 teaspoon granulated sugar
- 1 cup dry white wine
- 6 cups beef broth
- 1 leaf bay leaf
- 1 teaspoon fresh thyme
- 8 slices baguette slices
- 2 cups grated Swiss cheese
- to taste salt
- to taste black pepper
Instructions
Peel and thinly slice the yellow onions, and mince the garlic cloves.
In a large heavy-bottomed pot, heat the butter and olive oil over medium heat until melted.
Add the sliced onions to the pot, stirring to coat them evenly in the butter and oil. Sprinkle with a pinch of salt and cook, stirring occasionally, for 20-25 minutes or until the onions are golden brown and caramelized.
Add the minced garlic and granulated sugar to the caramelized onions and cook for an additional 2 minutes, stirring frequently.
Pour in the dry white wine and use a wooden spoon to scrape up any browned bits from the bottom of the pot. Simmer for 3-4 minutes until the wine reduces slightly.
Stir in the beef broth, bay leaf, and fresh thyme. Bring the soup to a gentle simmer, then reduce the heat to low and let it cook uncovered for 25-30 minutes. Taste and adjust the seasoning with salt and black pepper as needed.
While the soup simmers, preheat your broiler. Arrange the baguette slices on a baking sheet and toast them under the broiler for 1-2 minutes per side or until golden brown.
Ladle the hot soup into oven-safe bowls or crocks. Place a toasted baguette slice on top of each bowl, then sprinkle generously with grated Swiss cheese.
Place the bowls under the broiler for 2-4 minutes or until the cheese is melted, bubbly, and slightly golden.
Carefully remove the bowls from the broiler and let cool for 2-3 minutes before serving.
