Creamy Roasted Onion Soup

OnionHere's the last of the fruits of my weekend cooking binge (we still have quite a bit of everything stored away, but this is the last different meal, at least)--Creamy Roasted Onion Soup.

If the onion family had a reunion it would be this soup--onions, garlic, shallots, leeks (from the garden)--all the alliums are there for the party.  As I was chopping everything up I considered renaming it "The Soup of a Thousand Tears" or similar.  It sounds like it would scare away vampires for days, but actually, the roasting process makes the soup pleasantly sweet.  I like it with lots of crisped onions (as Martha suggests) and lumps of crusty bread or croutons mixed right in.
