Ingredients

• 6 large Yellow onions
• 3 tablespoons Unsalted butter
• 1 tablespoon Olive oil
• 1 teaspoon Salt
• 1 teaspoon Granulated sugar
• 2 tablespoons All-purpose flour
• 8 cups Beef stock
• 0.5 cup Dry white wine
• 3 sprigs Fresh thyme
• 1 whole Bay leaf
• 1 loaf Baguette
• 2 cups Gruyère cheese
• 1 pinch Black pepper

Directions

Step 1

Peel and thinly slice the yellow onions into even, half-moon shapes.

Step 2

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

Step 3

Add the onions, salt, and sugar to the pot. Stir well to ensure the onions are evenly coated.

Step 4

Cook the onions on medium-low heat, stirring frequently, until they become soft, golden brown, and fully caramelized (about 40-50 minutes). Be patient, as caramelization is essential for flavor.

Step 5

Sprinkle the flour over the onions and stir for 2-3 minutes to cook out the raw taste of the flour.

Step 6

Slowly add the beef stock, 1 cup at a time, while stirring to blend with the onions and flour. Add the white wine, thyme sprigs, and bay leaf.

Step 7

Bring the soup to a gentle simmer and cook uncovered for 30 minutes, occasionally skimming off any foam or impurities.

Step 8

While the soup simmers, preheat your oven's broiler. Slice the baguette into 1/2-inch-thick rounds and place them on a baking sheet. Toast under the broiler until golden brown on both sides.

Step 9

Ladle the soup into oven-safe bowls and place a slice of toasted baguette over each serving.

Step 10

Top each baguette slice with a generous amount of grated Gruyère cheese.

Step 11

Place the bowls under the broiler on a baking sheet and broil until the cheese is bubbling and golden brown, about 3-5 minutes.

Step 12

Carefully remove the bowls from the oven and let cool slightly before serving.

Step 13

Garnish with a pinch of black pepper and serve hot.
