Ingredients

• 3 tablespoons unsalted butter
• 1 tablespoon olive oil
• 6 medium (thinly sliced) yellow onions
• 1 teaspoon sugar
• 2 minced garlic cloves
• 1 cup dry white wine
• 4 cups beef stock
• 2 cups chicken stock
• 1 whole bay leaf
• 3 sprigs fresh thyme
• 1 teaspoon salt
• 0.5 teaspoon black pepper
• 1 small (sliced into 1/2-inch rounds) baguette
• 2 tablespoons olive oil (for croutons)
• 2 cups (shredded) gruyère cheese

Directions

Step 1

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

Step 2

Add the sliced onions and stir to coat them in the butter and oil. Cook for 10 minutes, stirring occasionally.

Step 3

Sprinkle the onions with sugar and continue to cook for 25-30 minutes, stirring frequently, until the onions are deeply caramelized and golden brown.

Step 4

Add the minced garlic and cook for 1-2 minutes until fragrant.

Step 5

Deglaze the pot with the white wine, scraping any browned bits from the bottom with a wooden spoon. Simmer until the wine reduces by half, about 5 minutes.

Step 6

Add the beef and chicken stock, bay leaf, and thyme sprigs. Bring the soup to a gentle simmer and cook for 20 minutes. Season with salt and pepper to taste.

Step 7

While the soup simmers, preheat the oven to 400°F (200°C) and arrange the baguette slices on a baking sheet.

Step 8

Brush the baguette slices with olive oil and bake for 8-10 minutes, flipping halfway, until golden and crisp.

Step 9

Remove the thyme sprigs and bay leaf from the soup, and ladle the soup into oven-safe bowls.

Step 10

Place a baked crouton on top of each bowl and sprinkle generously with shredded gruyère cheese.

Step 11

Place the bowls onto a baking sheet and broil in the oven for 2-3 minutes, or until the cheese is bubbly and golden.

Step 12

Serve immediately, garnished with fresh thyme if desired.
