Introduction: A rich, slow-cooked onion soup topped with toasted bread and melted cheese.
Cultural Background: Onion soup made this way is a comforting winter dish across San Marino, the onions cooked low and slow until deeply sweet, a technique shared broadly across the surrounding Italian regions.
Tips: Cook the onions low and slow without rushing; properly caramelised onions are the key to this soup’s deep flavour. Watch closely under the broiler, as the cheese can burn quickly.
Variations: Add a splash of brandy along with the wine for extra depth; use a mix of cheeses for a more complex melted topping.
Storage: Store the soup base (without bread and cheese) in an airtight container in the refrigerator for up to 3 days.
Reheating: Reheat the soup base gently on the stovetop, then top with fresh bread and cheese and broil just before serving.

FAQs:
Q: Why does the soup take so long to caramelise the onions?
A: Slow cooking breaks down the onions’ natural sugars, developing the deep sweetness essential to the dish’s flavour.
Q: Can this be made vegetarian?
A: Yes, use vegetable stock in place of beef stock for a fully vegetarian version.
