French Onion Soup

French onion soup is a classic, originating as a super-inexpensive but warming supper in 18th-century Paris. We especially love this dish on cold winter evenings. The rich flavors of the beef broth are complemented by caramelized onions and melted gruyere (if you can't find an inexpensive one, you can use swiss cheese instead). Onions are cheap, flavorful, and good for you, too—they are packed with vitamin C, flavonoids, and phytochemicals (compounds that have been shown to prevent some diseases). Our recipe is inspired by Julia Child, though we take a few cost- and time-saving shortcuts. We use water in addition to the beef stock, and you can repurpose your stale French bread here. This also is a perfect dish to freeze for another day.
