French Onion Soup Recipe | Simply Recipes
The trick to a great French onion soup is starting with good stock. French onion soup is usually made with beef stock. I've made delicious soup with stock from the leftover rib bones of a rib roast. Another important element is the proper caramelization of the onions. Caramelizing onions take at least thirty minutes of slow cooking the onions over medium high heat. The browning, or caramelizing, of the onions brings out the sweetness in them.
