What is it about French onion soup? The intensely sweet, caramelized onions? The rich, meaty beef broth? The gratinéed crouton on top? Given the options, I'd say all three. The classic soup is the final word on comfort food, especially in the dead of winter. This lightened up version has just under 300 calories per serving. If you're settling in for a cozy New Year's Eve at home (which, in my opinion, is the right way to do it), this is the perfect soup to let simmer as you await the glittery ball drop on TV. Welcome, 2015!
