Ingredients Needed

  • leeks
  • potatoes – yukon gold potatoes, russet potatoes, or red potatoes (use cauliflower for keto option). I like buying organic potatoes and leaving the peel on for this recipe as it makes it a bit more rustic and I love getting the added nutrition as well.
  • coconut milk – other non-dairy milk can work as well like oat milk, hemp milk, almond milk, or rice milk. However coconut milk, cashew milk, and hemp would be the creamiest. I don’t personally drink soy milk but that would be a nice creamy option as well.
  • onion
  • garlic
  • vegetable broth (chicken stock or beef broth can be substituted)
  • bacon or vegan bacon (optional but recommended)
  • coconut oil, vegan butter, or butter as desired
  • salt
  • black pepper

How To Make This a Vegan Potato Leek Soup

I’m not vegan (I used to be), and we actually like bacon, but I typically avoid eating pork due for many reasons. So for this recipe I’m sharing both a real and vegan bacon option. When choosing bacon, I recommend a sustainably farmed option.

How to Make This a Keto Leek Soup

Cauliflower is an amazingly good substitute for potatoes in all kinds of dishes and this smooth and creamy soup recipe is no exception. Simple swap out the potatoes with about 4 cups of cauliflower florets and you’ve got yourself a rich and creamy soup without all the carbs. For a lower carb but not keto soup, you could substitute half of the potatoes with 2 cups of cauliflower.

This Fauxtato Salad and these Cauliflower Mashed Potatoes are two other great dishes showing just how versatile the humble cauliflower can be.

Recipe Notes

Potatoes: I prefer to use organic potatoes and to leave the peels on.  

Any type of potato can be used. You can even use sweet potatoes and make this into a sweet potato soup if you’d like.

I like to leave chunks of potato in my soup, but you can blend it smooth if you’d like. For me, the pieces of potato make the soup feel and taste so much better.

Veggie Chopping: You can cut the veggies into larger pieces if you like, but I would keep the potatoes smaller to make sure they cook well.

Washing Leeks:

Leeks can have a lot of dirt between their layers.To clean them, cut off the dark green parts of the leek and discard (or save for making stock). Cut off the roots, then cut the leek in half lengthwise. Then cut the leek into pieces. Place the pieces in a small bowl of water and swish vigorously to release the dirt. Place in a colander and drain.

Serving Ideas

You can top this healthy potato leek soup with any of the following:

  • bacon or vegan bacon
  • chives
  • rosemary
  • sour cream, vegan sour cream, or cashew cream
  • olive oil
  • vegan cheese shreds

How to Store This Soup

This potato leek soup will keep in an airtight container in the fridge for up to 4 days or in the freezer for several months or longer if you have a truly airtight storage option.
