It's hard to believe how rich and creamy this potato-leek soup is even though there's not a drop of cream in it. Croutons topped with anchovy, olives and leek are a crunchy, savory foil to the soup. But skip them if you like and incorporate all the cooked leeks into the soup instead.
Tip: To clean leeks, trim and discard green tops and white roots. Split leeks lengthwise and place in plenty of water. Swish the leeks in the water to release any sand or soil. Drain. Repeat until no grit remains.
To make ahead: Cover and refrigerate the bisque and the crouton topping for up to 3 days.
