Talk about the ultimate comfort food! Creamy potato soup is probably in my top three – it's so cozy, it's full of yummy carbs and when it's silky smooth, it just totally hits the spot.

I used to love potato soup growing up, but since moving to New York, I haven't made a batch. I had a hankering the other week so I decided to whip up my own vegan potato leek soup. It kind of reminds me of a soup that my dad used to make growing up, just without all the butter, milk and cheese.

This soup is thick and creamy, but also completely dairy-free!

If you're making a traditional creamy soup the base is full-fat cream which helps give the soup that thick, creamy texture. But when you're dairy-free, there really isn't a great alternative.

Most non-dairy or plant milks are fairly watery so you won't get that same texture. The only one that really works is full-fat coconut milk, but then you're stuck with that coconut flavor which sometimes you just don't want (like with a vegan potato leek soup).

Well, friends, I have a solution: RAW CASHEWS!

I know it might sound strange, but when blended up, raw cashews can mimic full-fat cream almost exactly. And best of all? They're pretty much flavorless!

So that's what we're going to do with this recipe!

We're using raw cashews at the tail end of cooking and then blending up the soup in a blender to get it perfectly smooth. The end result is almost exactly like classic potato leek soup, but instead, it's vegan!

What about if you're nut-free? I know there will be some people who are allergic to cashews, so my recommendation would to add an extra cup of potatoes. You won't get quite the same creaminess, but as long as you've got a high powered blender, you'll still get a silky smooth potato leek soup!

Dairy-Free Potato Leek Soup

And yes, this truly is the perfect comfort food. Serve it up with some chopped rosemary on top, a little toast on the side and you've got the ultimate winter meal on the table. Oh – it also freezes well so it's great for meal prep too!

  1. Was looking for a dairy free version and discovered this one. I’m not vegan so used chicken stock. The only things I would change would be to add the cashews along with the potatoes to allow them to soften a bit more (other recipes I’ve used give them a soak) and an increase in the amount of leeks (at least 4 cups sliced). Otherwise it was a lovely soup for a dairy free friend.

  2. Hi , I just reading your blog it’s very interesting and healthy recipes I am interested to cook some of them , my daughter change her diet to be vegan 3 months ago because of her health she is 27 years old and she has arthritis rheumatoid and we really believe one day she will be completely cure from this disease, if she eat healthy food and gluten free. Thanks for your recipes

  3. Sunflower seeds can make a nice cashew sub, though they don’t get quite as smooth. They add a bit more of their own flavour but it adds a nice umami touch to a lot of dishes. Nut-free folks should consider experimenting with them.
