Think of these as the best part of French onion soup minus the broth. Better yet, they're in a form that's much easier to eat than the soggy wet bread, weighed down with cheese, that usually tops crocks of onion soup. Don't be surprised if these disappear before you get a chance to sample one yourself!
•Onions can be caramelized 1 week ahead and kept chilled.
•Bread slices can be toasted and cheese shredded 3 days ahead. Keep toasts in an airtight container at room temperature and keep cheese chilled.
