Actually, J. Kenji López-Alt has a great recipe for 15 minute caramelized onions [0].

I respect the hell out of Kenji but if properly caramelized onions are central to the dish (e.g. French onion soup, caramelized onions for a burger, etc.) I tend to come down on the side of Daniel Gritzer (also of Serious Eats).[0]
