A super easy version of french onion soup made in a slow cooker! Sweet caramelized onions in a tasty broth topped with toast and plenty of melted cheese! Yum!
French onion soup is so amazingly good but it requires a bit of time and effort to stand at the stove for a few hours, properly, caramelizing the onions… needless to say, I do not make it too often. This slow cooker version takes almost no effort at all and it’s almost as good! This version is as easy as slicing the onions, which, unfortunately, is still tear inducing, throwing them into the slow cooker to slowly caramelize before adding the broth and the remaining soup ingredients to cook a bit more. The onions take a long time to caramelize in the slow cooker, at 10+ hours, but they do not require any attention so you can let them cook overnight (or all day long). Once the soup is made you top it with toasted baguette slices along with plenty of cheese and broil to melt the cheese before digging in! Finally, a french onion soup that I can make all the time!
