Potato Leek Soup with Kale

Jump to Recipe Print Recipe

One of my favorite soups to make in the fall and winter is potato leek. Maybe it’s some of my Irish roots wanting to make up for the sad years I wasn’t eating potatoes, but no matter why, I love this stuff! The addition of kale is even something Tim accepts in this dish, and trust me, he is not kale’s biggest fan. Since it was first published years ago, I’ve made a few delicious upgrades to this dairy-free potato leek soup with kale so it’s creamier and more flavorful than ever!

Why Potato Leek Soup with Kale?

The first time potato leek soup even entered my brain space was in grad school when my roommate made it. She liked to use butter, cream and bacon. For me, with a meat-free diet, I made my own delicious version. It turns out it’s something meat lovers enjoy, too!

Poor potatoes have gotten a bad reputation from the ever-lying diet industry. How they got grouped with processed white foods, I’ll never know, as they’ve been enjoyed in pretty much every culture for many centuries. Potatoes are a great fall and winter good, and a delicious starch that provides energy for the brain and muscles, while keeping you satiated, too.

Leeks, like potatoes and kale, are a cold weather crop. If you haven’t explored them yet, they’re a member of the onion and garlic family, with anti-bacterial agents. If you enjoy those flavors, leeks provide a more mild version along with sweet and earthy tones.

After blending together those foods, kale adds a pop of color and texture.

Potato Leek and Kale Nutrition

On top of the energy potatoes provide, they contain 3 grams of protein, 2 grams of fiber, and 1/3 of your daily value of vitamin C. The most fun fact for me to share about potatoes is they have more potassium than a banana!

Leeks (as well as the onions and garlic in this recipe) are a source of prebiotic fiber. They also contain allicin and sulfides – phytochemicals which are linked to improved immunity and respiratory health.

Kale clearly has a great nutrition profile as it is rich in antioxidants, while providing fiber and nutrients like Vitamin C, K, iron, and folate.

Satisfying Taste and Texture

Sometimes I love chunky textured soups and others I want creamy. If you prefer a creamy textured soup but want to add the kale, use the immersion blender before adding your greens. Just by blending this soup when it’s done cooking, you’ll get a satisfying creamy texture. But, you can boost the physical satiety factor – and the creaminess – even more. Just blend in a rinsed can of white beans! Any type of white beans will work – cannellini, great northern, navy, take your pick. They’ll add even more fiber, plus some plant protein, both shown in research to increase feelings of fullness.

If you want to take it a step further, mix in a tablespoon of nutritional yeast to each bowl, or a 1/4 cup (and up to a 1/2 cup) to the entire recipe. This adds a boost of flavor, B-vitamins and protein. If you follow a completely vegan diet, or eat animal products very infrequently, make nutritional yeast a staple. Vitamin B-12 is hard to obtain in a vegan diet, and nutritional yeast is a good source. If cheese is part of your diet, you can add some cheddar, too.

  1. I made this today for lunch and enjoyed it very much. I did make a few changes as I never seem to be able to leave any recipe alone! I also doubled the leeks (because I had them on hand), added 5 reconstituted Shitake mushrooms very finely diced and some salt due to using an unsalted, homemade mushroom stock. I added a bit of rice to thicken the soup but the recipe as written may be sturdy enough – I probably used a bit extra stock. Lots of pepper and floated a jalapeno (later discarded) while the soup was cooking. I think this soup depends on a good flavourful veggie stock – so hard to find at the store. Thank you for posting.

    1. Great, Judith! Food is more fun when it’s personalized! I love the trader joes low sodium veg broth and while not low sodium picked up a good one at fresh market recently too! Trying this soup with some white beans this week – immersion blender should make it creamy. Love some spice like you added, too!

  2. I love that you have all the nutrition info too! I’ve never used leeks before but this seems like an easy recipe! Thanks for sharing

  3. Amazing!! I made this tonight for my family and EVERYONE loved it. My 15 year old said she wasn’t hungry for dinner and was going to just sit at the table. Feeling awkward, however, she grabbed a very small bowl then proceed to “slurp” it down and have more!! Apparently, it defeats “I’m not hungry syndrome” lol. We did have a bit of a twist with our in that we used 4 small beef brat dogs quartered and then cut into small (about 1/4 pieces) and added a small handful of chopped mushrooms. This one is definitely a keeper. Thank you so much for sharing this amazing recipe. – Sheila in Poulsbo, WA

    1. Sorry you felt that way! Did you add three full sized cloves of garlic and fresh rosemary? If spices like rosemary have been in the pantry for awhile they can lose their flavor. I’m big on bold flavors, so always try to ensure recipes are flavor packed before posting. The only other thought is to change the broth you use (I highly recommend the Trader Joe’s one I mention here) and to use nutritional yeast which is listed as optional.

  4. soup recipe sounds yummy! starting it for dinner tonite!
    i want to add white beans, but only have garbanzo beans…hmmm, whatcha think?
    i’ll check back and see if that makes sense to you here, or, i may skip…your thoughts?
    thanks, richard

    1. You can totally skip the beans! I would just add another protein source on the side if this is the main part of your meal. You could also roast the chickpeas and add as a crunchy topping when serving.
