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 with White 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?

I made this and loved it. I caramelized the onions in skillet then put in crockpot added extra can of beans and used beef broth. Made slice of Dave’s whole grain toast . I will cook again..
I’m so happy you enjoy it! Thank you for taking the time to leave your feedback.
Saw this soup on pintrest! Looks so good:)
Thanks so much! Hope you give it a try!
Just a FYI….. I am an older person and so naturally my eye sight isn’t what it used to be…and although I wear glasses I cannot see whatever is written or surrounded in yellow. I know if you never been here done that you would not realize. Just thought I would pass this along!! I am definitely going to make the soup though! Thanks!
Thanks so much for the feedback! I hope you enjoy the soup 🙂
I am so excited! I am trying your recipe as I type but I didn’t have enough onion (only 1) but I happened to have two large fennel bulbs (had to use dried seasoning unfortunately). Thank you so much for the post. Hopefully my improvisation works well with it!
That substitution sounds great! I think you’ll love this recipe! 🙂
I just made this and love it! I used dried herbs since I didn’t have fresh and it turned out great! I’d probably add another can of beans or less liquid next time since the onions sweat a lot and add lots of moisture. I also added a bay leaf because, why not!? I can’t wait to make this again-great recipe! I love the simple ingreafients!
So glad you loved it! Thanks for the feedback!
Can this be made without butter for a vegan recipe?
Yes! Absolutely! I make this recipe vegan all the time by using olive oil or coconut oil 🙂 Enjoy!
Sorry, but I did find the directions when I scrolled all the way down. Looking forward to trying the recipe!
I hope you enjoy it!
If saving time is important to you, then maybe this is your recipe. However, I’d rather put in the time and make a true classic French onion soup. I also thought the onions and the texture of the beans fought with each other. Will not be making this recipe again.
I’m sorry you didn’t enjoy this recipe. Classic French onion soup is certainly different than this recipe, which is based on a traditional French white bean soup.
This was so delicious! I also added a cup of dry quinoa, and sliced mushrooms and it turned out perfect. Even my picky 2 year old loved it. Thank you for sharing!
So glad you loved it! Thanks for the feedback!
Can you provide cook times to do a stovetop version?
I’ve made this recipe on the stovetop a few times. I caramelize the onions for about 20 minutes over medium heat and then simmer the soup for about another half hour or so.
Loved this recipe- thanks so much for sharing! I used Asiago cheese in addition to the parm. and toasted “roasted garlic french bread” to break up into pieces for the topping. I also served it with roasted broccoli on the side with the bread and it was a great flavor addition. I will definitely be making this soup again, thank you!!
So glad you enjoyed it!! Thanks for the positive feedback!
Do you drain the beans?
Yes!! Always drain and rinse 🙂
What specifically kind of white beans do you use? TIA
I most often use Cannellini beans for this recipe.
My husband loves French Onion soup – me not so much. I made this for him but I kept an open mind and tried it myself. I loved it!!! So did my husband !!!
So glad you loved it!! It’s one of our favourite soups too! 🙂 Thanks for the positive feedback!
Hey there!
What type of onion are you using?
Many thanks,
Great question! I just always use basic yellow onions unless otherwise indicated in the recipe. I find the yellow onions caramelize beautifully and have a nice mild flavour that my family enjoys 🙂
Can you use dried beans for this recipe?
Also, do you have instructions for making it in an Instant Pot?
Can’t wait to make this!
You can definitely use dried beans as long as you cook them first and then follow the recipe as directed. I don’t actually have an Instant Pot (yet!)…they’re sold out all over Europe and I need to get my hands on one! When I do, I’ll update the recipe for you with IP instructions 🙂
I’m making this right now! So tasty! (I did a can of beef broth and a 32 oz container of veggie stock.)
I was wondering if you could tell me your reasoning behind the lengthy cook time after the beans, broth, seasoning, etc are added? 3 hours seems like a lot, but I don’t cook with my crockpot very often.
Great question! I like the long cooking time because it really helps develop and deepen the flavours. I’m glad you enjoyed it!
Thanks for the reply 🙂 Great recipe!
Could I make this soup on the stove top instead of in a crockpot?
Yes, absolutely! Just caramelize the onions over low heat and cook as normal. 🙂
We thought this was just okay. We enjoyed eating it with some seasoned croutons and Parmesan cheese but I don’t think I’ll make again.
Sorry to hear that! 🙁
Looking forward to making this today – did you do the onions on low or high? (Or is is 3 hours on high/5hours on low?)
You caramelise the onions on high for anywhere between 3 to 5 hours. I have not tried caramelising them on low, so I couldn’t tell you what the time for that would be. Hope this helps! Let is know how it turned out!
What a wonderful combination of white beans and onion soup. I am definitely going to make this. I love white beans and French onion soup. Combining both of these would be so yummy. Thank you for sharing this recipe.
Exactly, French onion soup with beans and in a Crock Pot. I mean, come on what can be better than that?!☺️
Just made this in my InstantPot. Caramelizas the onions on high for an hour. Added the rest of the ingredients and cooked on high for 29 minutes. It came out so delicious! The whole family loved it
Thank you!
***cooked all ingredients on high for 20 minutes
Glad you loved it!
I made this exactly as shown. Both my husband & I thought it was fantastic! I loved how it came together, & the house smelled amazing! Thank you for this awesome recipe!
Happy to hear that you like the recipe!!🙂
This soup looks delicious! French onion is one of my faves.
Thanks Nancy!🙂
Very good soup. I did it on the stove top with beef broth and added Worcestershire sauce. It tasted exactly like French Onion soup! A real fast, flavorful soup!
Does this soup freeze well?
Yes, it does! And you can keep it frozen up to 3 months, just make sure you use proper freezer containers to protect it from freezer burn.

IM thinking of adding some chicken breasts to to soup. Maybe at the time when you add the beans and cook for 4 hours on high??
Thoughts?
You could add shredded chicken breast within the last hour of cooking.
