French onion soup

French onion soup was a type of soup originating in France, typically based on meat stock and onions, and often served au gratin (i.e. with a browned crust of grated cheese and breadcrumbs).

Kreacher served French onion soup to Harry Potter, Ron Weasley, and Hermione Granger on 1 September 1997. Harry thought it was "as good as [he] had ever tasted." While Kreacher's cooking had formerly been lacking, it improved significantly after he was given Regulus Black's locket, as did his relationship with Harry and his friends.
