    I love this soup so much! It's so good that I might eat this soup any time of the year. It's one of my favorite recipes.

    My Vegan Potato Leek Soup recipe is based off a potato soup recipe that I had as a kid. My mom made a very similar soup, often topped with cheese and bacon.

    This soup is my plant-based version. It uses cashew cream instead of heavy cream, and I add coconut bacon as a topping instead of regular bacon. Even with the swaps, it's just as delightful as the original version.

    Ingredient Notes & Substitutions

    I'm very excited about this soup! It only has a few ingredients and it's just as creamy and delicious as the original version.

    • Russet Potatoes: otherwise known as Idaho potatoes. Leave the skins on for extra fiber!
    • Carrot: whole carrots are best (as opposed to baby carrots) because they have a more earthy flavor. You don't need to peel - just wash thoroughly
    • Leek: usually these come in bunches of two at the store - a perfect excuse to double the recipe!
    • Vegetable Broth: use a brand with no added sugar and preferably no added salt
    • Cashew Cream: to make cashew cream blend soaked cashews and non-dairy milk - instructions below
    • Salt & Pepper
    • To serve: scallions and coconut bacon
    Vegan Potato Leek Soup Ingredients

    Step-By-Step Instructions

    Step 1. Soak the cashews in boiling water for about 30, up to overnight.

    Step 6. Remove from the heat. If desired, reserve 1 cup of potato chunks (I typically do not do this, but it's a great option if you want chunky soup). Transfer to a blender or food processor and blend until smooth, then add in the remaining chunks.

    Step 7. Serve topped with scallions and coconut bacon. Enjoy!

    FAQ & Expert Tips

    How do I properly clean leeks?

    Usually a good rinse works great, but if your leek is particularly dirty, slice the leek first, then rinse in a bowl of water to remove hidden dirt between layers.

    How do I make it thicker or thinner?

    For thicker soup, feel free to add more cashew cream or increase the amount of potato. For thinner soup, whisk in some warm broth.

    Storage

    Store in an airtight container for up to a week. Keep toppings separate.

    Can I freeze potato leek soup?

    Yes! Freeze in airtight containers for up to 6 months.
