We've swapped beef broth for chicken broth and onions for tender leeks but kept all the flavour in this lighter version of classic French onion soup. When you get home, just toast the baguette, broil the cheese and enjoy!

In slow cooker, combine leeks, butter, thyme, soy sauce, vinegar, Worcestershire sauce, salt and pepper; stir in broth and 3 cups water. Cover and cook on low for 8 hours.

Arrange baguette slices on baking sheet; broil, turning once, until golden brown, about 2 minutes.

Stir Gruyére cheese with parsley. Place ovenproof soup bowls on baking sheet; ladle soup into bowls. Top each bowl with 2 baguette slices; sprinkle cheese mixture over top. Broil until cheese is bubbly and golden, about 2 minutes.

Makes 8 to 10 servings.
