Ingredients

• 4 tablespoons unsalted butter
• 2 tablespoons olive oil
• 6 large yellow onions
• 1 teaspoon granulated sugar
• 2 teaspoons honey
• 3 garlic cloves, minced
• 1 cup dry white wine
• 6 cups beef broth
• 1 bay leaf
• 3 sprigs fresh thyme, tied in a bundle
• 1 teaspoon salt
• 0.5 teaspoon black pepper
• 1 baguette, sliced into 1-inch pieces
• 2 cups Gruyère cheese, shredded

Directions

Step 1

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

Step 2

Peel and thinly slice the onions. Add them to the pot, stirring to coat them evenly in the butter and oil.

Step 3

Sprinkle the onions with sugar to help with caramelization. Cook the onions over medium-low heat for 35–40 minutes, stirring often, until they are deeply golden and caramelized.

Step 4

Add the honey and minced garlic to the pot, stirring for 1–2 minutes until fragrant.

Step 5

Pour in the white wine, scraping the bottom of the pot to deglaze and lift any caramelized bits. Simmer until the wine has reduced by half, about 5 minutes.

Step 6

Add the beef broth, bay leaf, thyme bundle, salt, and pepper. Stir and bring to a simmer. Reduce the heat to low and cook for 20–25 minutes to let the flavors meld.

Step 7

While the soup simmers, preheat your oven to 400°F (200°C) and arrange the baguette slices on a baking sheet. Toast in the oven for 8–10 minutes until lightly golden.

Step 8

Remove the bay leaf and thyme bundle from the soup, then ladle the soup into oven-safe bowls or ramekins.

Step 9

Top each bowl with a piece of toasted baguette, then generously sprinkle Gruyère cheese over the bread.

Step 10

Place the bowls on a baking sheet and broil in the oven on high for 2–4 minutes, or until the cheese is melted, bubbly, and golden brown.

Step 11

Carefully remove the bowls from the oven. Let cool for 5 minutes before serving.
