I make french onion soup using beef broth, splash of Worcestershire sauce, onions and let it simmer until everything is cooked and onions are soft. If I am really feeling ambitious, I roast the onions first, then put them in the soup. Roasting veggies prior to "souping" them is supposed to bring out their flavors more (or that's what I heard on a radio show a few years back) I am guessing my taste buds think so, because I now roast veggies a lot before adding them to different dishes I am making, sometimes I even pre-roast for future meals. And grilling them before using them in dishes adds an even better flavor.
Oh, and in the french onion soup I of course finish with croutons & cheese.
