Ingredients

• 3 tablespoons unsalted butter
• 2 tablespoons olive oil
• 6 large yellow onions
• 1 teaspoon granulated sugar
• 2 tablespoons all-purpose flour
• 1 cup dry white wine
• 8 cups beef stock
• 1 bay leaf
• 2 sprigs fresh thyme
• 6 pieces baguette slices
• 2 cups Gruyère cheese, shredded
• 0 to taste salt
• 0 to taste black pepper

Directions

Step 1

Peel and thinly slice the onions into even, thin slices.

Step 2

Heat the butter and olive oil in a large heavy-bottomed pot over medium heat.

Step 3

Add the onions and stir to coat them in the butter and oil mixture.

Step 4

Sprinkle the sugar over the onions, lower the heat to medium-low, and cook, stirring frequently, until the onions are deeply golden and caramelized (this will take about 40 minutes).

Step 5

Stir in the flour and cook for an additional 2 minutes, stirring constantly to avoid lumps.

Step 6

Deglaze the pot by pouring in the white wine, scraping the bottom of the pot with a wooden spoon to release any browned bits.

Step 7

Add the beef stock, bay leaf, and thyme sprigs, and bring to a gentle simmer.

Step 8

Season the soup with salt and pepper to taste, and let it simmer uncovered for 30 minutes. Remove the thyme sprigs and bay leaf before serving.

Step 9

Preheat your oven’s broiler to high. Toast the baguette slices on a baking sheet until golden brown on both sides.

Step 10

Ladle the soup into oven-safe bowls and place them on a baking sheet.

Step 11

Place a toasted baguette slice on top of each bowl of soup and generously sprinkle Gruyère cheese over the top.

Step 12

Carefully transfer the baking sheet to the oven and broil until the cheese is bubbly and golden, about 2-3 minutes.

Step 13

Serve the soup hot with an extra slice of baguette on the side, if desired.
