Recipe Information
Ingredients
- 6 medium sweet onions (such as Vidalia)
- 4 tablespoons unsalted butter
- 2 tablespoons olive oil
- 2 large garlic cloves
- 1 teaspoon fresh thyme leaves
- 2 pieces dried bay leaves
- 2 tablespoons all-purpose flour
- 1 cup dry white wine
- 6 cups beef broth
- to taste salt
- to taste black pepper
- 6 pieces baguette slices
- 1.5 cups grated Gruyère cheese
Instructions
Peel and thinly slice the sweet onions.
In a large, heavy-bottomed pot over medium heat, melt the butter and add the olive oil.
Add the sliced onions to the pot, stirring to coat them in the fat. Cook, stirring occasionally, for 25-30 minutes until the onions are deep golden brown and caramelized.
Mince the garlic and add it to the pot along with the fresh thyme and bay leaves. Cook for 1-2 minutes until fragrant.
Sprinkle the flour over the onions and stir well to combine. Cook for another minute to remove the raw flour taste.
Deglaze the pot by pouring in the white wine, scraping up any browned bits at the bottom of the pot. Let it simmer for 2-3 minutes until slightly reduced.
Pour in the beef broth and bring the soup to a gentle simmer. Allow it to cook for 20-25 minutes, stirring occasionally. Remove and discard the bay leaves.
Season the soup with salt and black pepper to taste.
Preheat the broiler. Place the baguette slices on a baking sheet and toast lightly under the broiler until crisp.
Ladle the hot soup into oven-safe bowls. Place a baguette slice on top of each bowl and sprinkle generously with the grated Gruyère cheese.
Place the bowls under the broiler for 2-3 minutes or until the cheese is melted and bubbling. Carefully remove from the oven.
Serve immediately and enjoy the comforting bowl of sweet onion soup.
