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
• 0 to taste salt
• 0 to taste black pepper
• 6 pieces baguette slices
• 1.5 cups grated Gruyère cheese

Directions

Step 1

Peel and thinly slice the sweet onions.

Step 2

In a large, heavy-bottomed pot over medium heat, melt the butter and add the olive oil.

Step 3

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.

Step 4

Mince the garlic and add it to the pot along with the fresh thyme and bay leaves. Cook for 1-2 minutes until fragrant.

Step 5

Sprinkle the flour over the onions and stir well to combine. Cook for another minute to remove the raw flour taste.

Step 6

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.

Step 7

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.

Step 8

Season the soup with salt and black pepper to taste.

Step 9

Preheat the broiler. Place the baguette slices on a baking sheet and toast lightly under the broiler until crisp.

Step 10

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.

Step 11

Place the bowls under the broiler for 2-3 minutes or until the cheese is melted and bubbling. Carefully remove from the oven.

Step 12

Serve immediately and enjoy the comforting bowl of sweet onion soup.
