Recipe Information
Ingredients
- 6 large yellow onions
- 4 tablespoons unsalted butter
- 2 tablespoons olive oil
- 3 whole garlic cloves
- 4 sprigs fresh thyme
- 1 large bay leaf
- 1 cup dry white wine
- 6 cups low-sodium beef broth
- 4 thick slices bread slices
- 2 cups Gruyère cheese
- to taste salt
- to taste black pepper
Instructions
Peel and thinly slice the yellow onions into even slices.
In a large heavy-bottomed pot, melt the unsalted butter and olive oil over medium heat.
Add the sliced onions and a pinch of salt. Stir to coat the onions evenly in the butter-oil mixture.
Cook the onions over medium-low heat, stirring occasionally, for 40-50 minutes, or until they are deeply caramelized and golden brown.
Add the minced garlic, thyme sprigs, and bay leaf to the caramelized onions. Stir and cook for 1-2 minutes until fragrant.
Deglaze the pot with the dry white wine, scraping up any browned bits from the bottom of the pot. Let it simmer for 3-4 minutes until the wine reduces slightly.
Pour in the beef broth and bring the soup to a gentle simmer. Let it cook uncovered for 25-30 minutes, allowing the flavors to meld together. Discard the bay leaf and thyme sprigs.
Preheat your broiler. Arrange the bread slices on a baking sheet and toast them under the broiler until golden brown on both sides.
Ladle the soup into oven-safe bowls and place a toasted bread slice on top of each bowl.
Generously sprinkle the Gruyère cheese over the bread slices, ensuring that some cheese overlaps onto the edge of the bowl for a crispy topping.
Place the bowls on a baking sheet and broil for 2-3 minutes, or until the cheese is melted, bubbly, and lightly golden brown.
Carefully remove the soup bowls from the broiler. Let cool for 2-3 minutes and season with salt and freshly ground black pepper to taste before serving.
