Slow Cooker Caramelized Onions

Place the onions and butter in a slow-cooker and cook on low 12 - 24 hours until the onions are deep golden brown and very soft. Different slow-cookers will take different amounts if time - it's almost impossible to overcook this.

Use the onions and liquid to flavor soup, stock, stews. They make a wonderful addition to risotto, a perfect pasta sauce and the worlds best pizza topping (drain off the liquid first).
