Slow Cooker Guinness French Onion Soup

I LOVE French Onion Soup!  When we go out to a restaurant if I hear they have french onion soup on the menu it’s a guarantee that I will be ordering it.  A couple of the reasons why I always ordered it was because I often only found it at high end restaurants and I thought it entailed a lot of steps that were out of my league of making at home, or at least making quickly and easily.  A couple of years ago I learned how wrong I was.  Frankly french onion soup is one of the easiest soups that I make at home.  I’ve made it even easier with this Slow Cooker Guinness French Onion Soup.  The time consuming part is completed in your slow cooker freeing up your day.

Recently I’ve taken to adding to Guinness to my french onion soup because it really adds an extra flavor.  This dark beer tends to add in another very robust flavor to this Slow Cooker Guinness French Onion Soup without being extremely overpowering.  All that being said if your don’t actually like to cook with alcohol or just don’t have any Guinness in the house you can easily sub it out for extra beef broth.  Guinness is not a beer of choice by anyone I know so it’s not something I always have on hand but I’ll try my best to keep a few around for when the weather is turning colder and I have a craving and don’t want to head out to a high end restaurant to curb it.
