Storage

Store the leftover soup in an airtight container in the fridge for up to 5 days. You can also freeze the soup for up to 3 months in a freezer-safe container.

To reheat the refrigerated soup, place it in a pot on medium-high heat and stir until heated through. You can also microwave individual servings of the soup for about 2 minutes, stirring halfway through. Enjoy!

Pro Tips 

Here are a few tips to make sure that your vegan leek potato soup turns out perfectly every time that you make it.

  • I like to use a broth pot, but you can use medium size stock or a soup pot that you have on hand.
  • Using dairy-free butter instead of oil to saute the vegetables really adds so much more flavor to this recipe. So, I recommend that you use butter if you have it.
  • For this recipe, we will be using the white section of the leek only. Save the green top to make another batch of homemade vegetable broth.
  • If you want to add more vegetables you can add a white or light yellow carrot to the vegetables when you saute time. I don’t recommend that you use an orange carrot as it will change the color of your soup.
  • I prefer to use an immersion blender to puree the soup, however, if you don’t have an immersion blender you can use a regular blender, just be careful because the soup will be hot.

FAQs

Do you have questions about this vegan soup recipe? Here are the answers to the most commonly asked questions about this recipe.

Do you use all of the leeks for soup?

No, I recommend that you only use the white part for the soup, it really contains the best flavor.

How do you thicken leek and potato soup?

The potatoes and oat milk really do a good job of thickening this soup. However, if you find that it is too thin to your taste, you can stir in a cornstarch slurry while the soup is simmering to thicken it further.

Where do you cut leeks for soup?

I like to slice the white part of the leeks like onions. However, I recommend that you slice them very thinly so that they cook quickly.
