French Onion Soup is one of my favourite soups ever – it’s just SO delicious and flavourful and then there’s all that delicious bread and melted cheese on top. I mean, who could resist?? I’ve made real, traditional French Onion Soup several times at home with amazing results using this recipe for Anthony Bourdain’s Les Halles French Onion Soup. It’s seriously to die for, but it’s terribly time consuming – not something I can wrap my head around in the stage of life I’m currently in.

I will make the time to try Anthony Bourdain’s recipe again soon, but until then I’ll be making this Crock Pot French Onion Soup with White Beans instead. It’s an absolutely delicious version of French Onion Soup because you can actually caramelize the onions in your slow cooker (what?? I know!). And the addition of white beans and oregano adds a very subtle Italian twist – it’s kind of a mash-up between Italian White Bean Soup and French Onion Soup and the results are simply heavenly.

And instead of broiling the soup with croutons and cheese on top before serving, I make a simple batch of homemade croutons (you can even use store-bought if you’d like!) and serve the soup with a few croutons on top and, of course, some shredded Parmesan cheese. It’s just one more way to make this Crock Pot French Onion Soup withWhite Beans even more low-maintenance.
Kitchen Tools I Recommend:
Our family actually eats this Crock Pot French Onion Soup with White Beans all throughout the year. It’s warm and hearty enough to be served in the winter time but it’s also light-tasting enough to enjoy on a rainy spring or summer day as well. And because it’s made in the slow cooker it’s really one of those set-it and forget-it recipes that’s convenient any time of the year, am I right?
