Ingredients:

6 large yellow onions, thinly sliced

8 cups beef broth
1/2 cup dry white wine
2 bay leaves
1 teaspoon dried thyme
Salt and freshly ground black pepper to taste
1 baguette, sliced and toasted
1 1/2 cups grated Gruyère cheese

Directions:

Melt butter in a large pot over medium heat. Add onions and cook, stirring frequently, until caramelized (about 40 minutes).
Add garlic and cook for another minute.
Pour in wine, and scrape any browned bits off the bottom of the pot.
Add beef broth, bay leaves, and thyme. Season with salt and pepper.
Bring to a boil, then reduce heat and simmer for 30 minutes.
Preheat the oven broiler.
Ladle soup into oven-safe bowls. Top each with a slice of toasted baguette and a generous amount of Gruyère.
