Paleo French Onion Soup
This healthy spin on French Onion Soup is all about the chunky onion broth. The soup is made in the slow cooker and loaded with sweet caramelized onions in a rich broth. This Paleo French Onion Soup is Grain Free, Gluten Free, Dairy Free, Whole30 and Vegan.
This is my Grain Free and Dairy Free spin on French Onion Soup. I realize that it’s missing what many would view as the best part of the classic French dish, the crusty bread topping covered in gooey cheese, but it turns out that chunky onion broth is actually the star.
Big chunks of tender caramelized onion add a surprising amount of substance to this soup and the broth is incredibly flavourful thanks to a few special ingredients and long cook time.
This is a soup that can’t be rushed, the onions need to be slowly cooked until they are caramelized, and then cooked for another 4 to 6 hours in a slow cooker with liquid so that the soup can develop a rich slightly sweet flavour.
While the traditional version of the soup uses sugar and port or white wine, the same flavour profile is created in this healthier version using apple juice and balsamic vinegar.
If you don’t have a slow cooker this could also be made on the stove top in a big pot on low heat. I would recommend cooking it on the stove for 1 ½ to 2 hours, but the longer, the better the flavour.

Instant Pot Instructions

It looks really good but balsamic vinegar is SCD illegal. I will try to make it without the balsamic vinegar and thank you for this amazing site.
Thanks for the comment Dara! Balsamic Vinegar is actually allowed on the diet if it is high quality aged balsamic, the cheaper stuff with added sugar is not allowed
This is awesome, made it today!
So happy to hear that!
If I don’t have a slow cooker with a sear/saute method, how would you recommend doing the first step?
I would saute the onions on the stove top and then transfer them to the slow cooker.
My children loved this recipe. Thank you so much for sharing it!
