French onion soup is about as classic as it’s possible for a dish to be, and there are few other soups that we find as satisfying, especially during the winter time. Still, as simple as it is, actually preparing and cooking it can be a time-consuming, tricky process, especially since the key element is cooking the onions slowly and carefully to caramelize them. What do if you’re craving the tasty soup but don’t have the time to stand over the stove? The answer, when you think about it, is obvious: get your slow cooker involved and let it worry for you! Here’s how to use it to make PERFECT French onion soup.
