Ingredients

• 4 tablespoons unsalted butter
• 4 large yellow onions, thinly sliced
• 2 cloves garlic, minced
• 1 teaspoon brown sugar
• 2 tablespoons all-purpose flour
• 5 cups beef broth
• 1 cup dry white wine
• 1 piece bay leaf
• 1 teaspoon fresh thyme
• 1 teaspoon salt
• 1 teaspoon black pepper
• 6 pieces baguette slices, toasted
• 2 cups Gruyère cheese, shredded
• 0.5 cup Parmesan cheese, grated

Directions

Step 1

Melt the butter in a large pot over medium heat. Add the sliced onions and cook for 10 minutes, stirring occasionally.

Step 2

Add the minced garlic and brown sugar to the pot. Reduce the heat to low and cook the onions for 25-30 minutes, stirring frequently, until caramelized and golden brown.

Step 3

Sprinkle the flour over the onions and stir well to coat. Cook for another 1-2 minutes to eliminate the raw flour taste.

Step 4

Gradually add the beef broth and white wine, stirring constantly to avoid lumps. Bring the mixture to a simmer.

Step 5

Add the bay leaf, fresh thyme, salt, and black pepper. Simmer the soup for 20 minutes, stirring occasionally. Remove the bay leaf and adjust seasoning if necessary.

Step 6

Preheat the oven to broil. Ladle the soup into oven-safe bowls and top each with a toasted baguette slice.

Step 7

Sprinkle a generous amount of Gruyère and Parmesan cheese over the bread. Place the bowls on a baking sheet and broil in the oven for 2-3 minutes, or until the cheese is melted and bubbly.

Step 8

Carefully remove the bowls from the oven and let them cool slightly before serving. Enjoy your cheesy onion soup!
