  • 3 large white onions, sliced
  • 2 tablespoons brown sugar
  • 2 (32-ounce) containers beef broth, optionally low-sodium
  • 1 tablespoon Worcestershire sauce
  • 1 clove garlic, minced

Directions

Step 1 -In a large, nonstick pan over medium-low heat, melt the butter.

Step 3 -Add the caramelized onions, the beef broth, the Worcestershire sauce, the garlic, the dry sherry, 4 of the thyme sprigs, and the bay leaf to a slow cooker.

Step 4 -Cover the slow cooker and cook on low until the flavors meld together, about 6-8 hours.

Step 6 -Remove and discard the thyme sprigs and the bay leaf from the soup.

Step 7 -Ladle the soup into heatproof serving bowls and place them on a baking sheet.

Step 8 -Place 1 slice of the bread in each bowl, then top each evenly with the Gruyère cheese, the Emmental cheese, and the parmesan cheese.

Step 9 -Broil the soup until the cheeses on top are melted and slightly browned, about 2-3 minutes.

Step 10 -Garnish with the extra thyme leaves and serve hot.
