Ingredients

• 6 large yellow onions
• 3 tablespoons olive oil
• 2 tablespoons unsalted butter
• 3 cloves garlic
• 2 sprigs fresh thyme
• 1 cup dry white wine
• 6 cups beef stock
• 1 bay leaf
• 1 teaspoon salt
• 0.5 teaspoon black pepper
• 6 baguette slices
• 1 cup Gruyère cheese

Directions

Step 1

Preheat your oven to 400°F (200°C).

Step 2

Peel and thinly slice the onions. Spread the sliced onions evenly on a baking sheet.

Step 3

Drizzle the olive oil over the onions and toss to coat evenly. Roast in the preheated oven for 35-40 minutes, stirring every 10 minutes, until the onions are golden brown and caramelized.

Step 4

In a large Dutch oven or pot, melt the butter over medium heat. Mince the garlic and add it to the pot, sautéing until fragrant (about 1 minute).

Step 5

Transfer the roasted onions into the pot. Add the thyme sprigs and cook for an additional 5 minutes, stirring occasionally.

Step 6

Pour in the dry white wine, scraping the bottom of the pot to deglaze and release any browned bits. Simmer for 5 minutes to let the wine reduce slightly.

Step 7

Add the beef stock, bay leaf, salt, and black pepper. Bring the soup to a simmer, then reduce the heat to low and let it cook gently for 30 minutes, allowing the flavors to meld.

Step 8

While the soup simmers, prepare the baguette slices. Toast them under the broiler until crisp, about 1-2 minutes per side.

Step 9

Preheat your broiler. Ladle the soup into oven-safe bowls. Place a toasted baguette slice over the soup in each bowl, then sprinkle generously with shredded Gruyère cheese.

Step 10

Place the bowls on a baking sheet and broil for 2-3 minutes, or until the cheese is melted and bubbly.

Step 11

Allow the soup to cool slightly before serving. Garnish with additional thyme leaves if desired.
