Ingredients

• 4 tablespoons unsalted butter
• 2 tablespoons olive oil
• 6 cups yellow onions (thinly sliced)
• 1 teaspoon sugar
• 2 garlic cloves (minced)
• 1 cup dry white wine
• 6 cups beef stock (high-quality)
• 1 bay leaf
• 2 sprigs fresh thyme (or 1 tsp dried)
• 1 teaspoon salt
• 0.5 teaspoon black pepper
• 8 slices baguette (sliced)
• 2 cups Gruyère cheese (grated)

Directions

Step 1

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

Step 2

Add the sliced onions and cook, stirring frequently, until they begin to caramelize, about 15-20 minutes.

Step 3

Sprinkle the sugar over the onions and continue cooking for another 10-15 minutes, stirring often, until they are deeply golden and caramelized.

Step 4

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

Step 5

Pour in the white wine, scraping the bottom of the pot to deglaze and loosen any browned bits. Simmer for 3-5 minutes until the wine has mostly evaporated.

Step 6

Add the beef stock, bay leaf, thyme, salt, and black pepper to the pot. Bring the soup to a gentle simmer and cook for 20 minutes, allowing the flavors to meld together.

Step 7

While the soup simmers, preheat the broiler and arrange the baguette slices on a baking sheet. Toast the slices under the broiler until golden brown on both sides.

Step 8

Remove the bay leaf and thyme sprigs from the soup. Taste and adjust seasoning with additional salt and pepper, if needed.

Step 9

Ladle the hot soup into oven-safe bowls, place 1-2 toasted baguette slices on top of each bowl, and generously sprinkle with Gruyère cheese.

Step 10

Place the bowls on a baking sheet for easier handling, then broil in the oven for 3-5 minutes, or until the cheese is melted and bubbly.

Step 11

Carefully remove from the oven and serve immediately. Enjoy the soup while it's hot and cheesy!
