Ingredients

• 6 medium yellow onions
• 3 tablespoons unsalted butter
• 1 tablespoon olive oil
• 1 teaspoon granulated sugar
• 1 teaspoon salt
• 1 cup dry white wine
• 6 cups beef broth
• 1 bay leaf
• 2 sprigs fresh thyme
• 1 loaf baguette
• 2 cups (grated) Gruyere cheese
• 0.5 teaspoon black pepper

Directions

Step 1

Peel the onions and thinly slice them into half-moon shapes.

Step 2

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

Step 3

Add the sliced onions, sugar, and salt to the pot. Stir well to coat the onions in the butter mixture.

Step 4

Reduce heat to medium-low and cook the onions, stirring frequently, for 45-55 minutes, until deeply caramelized and golden brown.

Step 5

Once the onions are caramelized, increase the heat to medium and deglaze the pot by adding the white wine. Scrape the bottom of the pot to release the browned bits.

Step 6

Let the wine cook for 2-3 minutes until mostly evaporated.

Step 7

Add the beef broth, bay leaf, and thyme sprigs to the pot. Stir well, bring to a boil, then reduce the heat to low and simmer for 20-25 minutes.

Step 8

Season with black pepper to taste and adjust salt if needed. Remove the bay leaf and thyme sprigs before serving.

Step 9

While the soup simmers, preheat your oven to 375°F (190°C) and slice the baguette into 1/2-inch thick rounds.

Step 10

Place the baguette slices on a baking sheet and toast them for 8-10 minutes, flipping halfway through, until golden and crisp.

Step 11

Set oven-safe bowls on a baking sheet and ladle the soup into each bowl.

Step 12

Top each bowl with a slice or two of toasted baguette, then generously sprinkle grated Gruyere cheese over the bread.

Step 13

Place the bowls under a preheated broiler for 2-4 minutes, or until the cheese is melted and bubbly with golden spots.

Step 14

Carefully remove the bowls, let cool slightly, and serve the soup hot.
