Spring Leek Soup with Gruyere Toasts
Spring Leek Soup is the perfect way to celebrate the tender leeks of spring! Think of this soup as the delicate cousin of French Onion soup. Both soups are topped with an oversized, melted cheese covered crouton, but instead of the deep, dark broth of French Onion soup, this leek soup has a light buttery broth and is prepared in a fraction of the time - 20 minutes from start to finish.
