Taste, season, balance the soup
Ladle the soup into the crocks until it’s just below the brim. Layer the croutons on top of the soup so that it serves as a foundation for the cheese.
Seal with 1-2 slices of cheese, top with some Asiago if using.
Place the crock on a baking tray lined with tin foil and pop into the oven for 5 mins or until the top begins to bubble, turns slightly brown and forms a cheese-like crust.
