French onion soup is one of my favorite cool weather meals. I love how each spoonful warms me up from the inside out. And the big flavors make it so satisfying. Making the true version of this soup can take an entire afternoon, and more patience than I typically have on hand. If you feel the same way then you’ll love this version. All you need to do is slice the onions and saute them with butter, then let the slow cooker do the rest.
