This vegan leek and potato soup is creamy, healthy, and only takes 40 minutes to make. This soup packs a rich, hearty, mouth watering flavor, despite not using any dairy ingredients.

this recipe

Leek and potato soup is the ultimate comfort food. It’s full of hearty carbs from the potatoes, which is balanced by the fresh kick of leeks. And it is oh so creamy!

That creaminess usually comes from … well … cream. But I found the perfect way to add creaminess to a vegan leek and potato soup: cashews! Cashews are full of healthy fats, and when blended up they have a similar richness to heavy cream. They make this soup rich and soothing, while still being vegan and healthy.

I recommend serving a bowl of this soup on a cold evening, topped with some garlic and rosemary gluten-free croutons.

What You’ll Need

Make sure to check out the recipe card at the bottom of the page, as it has the exact quantities for all of the ingredients.

  • Olive oil
  • Garlic cloves
  • Leeks
  • Russet potatoes
  • Sea salt
  • Black pepper
  • Vegetable broth – You can use low sodium for a healthier soup.
  • Bay leaves
  • Cashews – Make sure the nuts are both raw and unseasoned.
  • Fresh rosemary

Why Russet Potatoes?

Russets are the perfect potato for a creamy soup, such as this one. Because russets are so high in starch, they add a thickness to the soup.

How to Make Vegan Leek and Potato Soup

This recipe has rich and complex flavors, but only takes about 40 minutes to make. Here’s how.

Sauté leeks and garlic. Heat the oil in a large pot or dutch oven, then add the leeks and garlic. Sauté until the leeks are tender, which will take about 4 minutes.

Add the potatoes. Put the potatoes in the pot, and add the salt and pepper. Sauté for 2 more minutes.

Add the broth. Pour the vegetable broth into the pot, and add the bay leaves. Stir to combine, and bring the soup to a boil. Lower the heat until the soup is simmering, and cook until the potatoes are tender, about 15 to 20 minutes.

Finish. Stir the cashews into the soup and cook for a minute, then pour the soup in a blender. Blend on high speed until the soup is completely smooth. Serve the soup, and garnish with rosemary.

Tips for Success

Here are a few things you can do to make sure that your vegan leek and potato soup is creamy, flavorful, and perfect.

  • Wash the leeks. Leeks require more washing than the average vegetable, because they get a lot of dirt and grit in between their layers. Wash them thoroughly to make sure that your soup isn’t gritty at all.
  • Use a good quality broth. This soup doesn’t have a lot of ingredients, so using a good quality vegetable broth can make a huge difference.A great broth will take this soup to the next level.
  • Don’t overcook the cashews. You want to cook the cashews for a minute before blending the soup, but don’t cook them more than that. If you cook the cashews for too long, they’ll lose some of the flavor and texture that makes this soup so similar to the dairy versions.

How to Store Vegan Leek and Potato Soup

You can keep this soup in the fridge for up to 4 days. Just make sure to store it in an airtight container, and then reheat on the stove top or in the microwave.

Can This Recipe Be Frozen?

Sure! Put the soup in an airtight container and freeze it for up to 1 month. Defrost in the fridge or the microwave before reheating.
