Vegan Potato Leek Soup

Easy and hearty potato leek soup with a base of aromatics and veggie broth pureed until super creamy and silky without the addition of heavy cream. No oil, dairy free, as healthy as can be but also comforting and exceptionally delicious, this soup is simply the best! Don’t be surprised if you find yourself making this one all year long like the finest timeless chowder.

About the Leeks

A part of the allium family that includes garlic, shallots and onions, leeks contain a bunch of good for you sulfur compound with health benefits. From protecting against cancers to lowering blood pressure and the LDL (bad) cholesterol levels to eye health, leeks most definitely earn their VIP spot in the whole foods pantry.

You’ll notice that most recipes only call for the white and pale green parts of the leeks to be used, however the dark greens are just as edible and caramelize beautifully delivering plenty of flavor. So I like to use those as a garnish, no sense in wasting something perfectly good and delicious. You could certainly just add them all into the soup pot but keep in mind that is going to affect the final color of the soup. To achieve that golden hue shown in the photos you must only use the lighter parts.

The Potatoes

Yukon gold potatoes are always my top choice for creamy soups and even mashed potatoes. A quick scrub and rinse is all they need and in the soup they go. Although not my favorites, Russet potatoes would be fine in a pinch but they require peeling first as their skins are quite tough and will change the color of your soup to a not so golden brown.

Recipe Tips + FAQ

  • How to make the soup chunky? For a chunky texturereserve about a third of the caramelized leeks and some of the cookedpotatoes to add back into the soup after you puree the rest.Lightly mash the reserved potatoes before mixing back it.
  • What can I use instead of cashews? To make the soup nut free you can use a 15oz can of white beans instead of cashews.
  • Can I use coconut milk instead of cashews? You could but I do not recommend. Coconut milk has a certain flavor and you really want something neutral here that won’t overpower the delicate flavor of the leeks.
  • Can you freeze the leftovers ? Absolutely yes you can. Store any leftover soup in freezer proof containers for up to 3 months. Remember to thaw it out in the fridge before reheating on the stovetop or microwave oven. The soup also keeps well in the fridge for 4-5 days, but let’s not kid ourselves though, there won’t be any leftovers.
  • Is the green part of the leeks edible? Yes, the entire leek is edible and super delicious, I like to reserve the green tops to caramelize and serve as a garnish on top of the soup.

US Customary - Metric

Instructions

  • Cut the root ends off of the leeks then cut them in half lengthwise. Thinly slice them and add to a large bowl of cold water and rinse well. Allow them to sit for a few minutes for the dirt particles to fall to the bottom of the bowl. Scoop the leeks out using your hands and transfer to a clean bowl.

    1 extra large leek

  • Meanwhile preheat a heavy bottom stock pot over medium flame. Sauté the leeks in a light drizzle of olive oil ( use a splash of water, veggie stock or white wine for WFPB & Plantricious diets) and a pinch of sea salt until wilted and they start to caramelize at the edges. You might need to add more liquid so keep a close eye on them. (Optional: reserve about 1/3 of the caramelized leeks for garnish or to add back into the soup if a chunky texture is desired. In my opinion this really takes the soup over the top.)

    1 extra large leek

  • Add the carrots, bay, thyme and cashews and give everything a good stir. Add the potatoes then pour in the vegetable stock.

    2 lb golden potatoes, 1 large carrot, 3/4 cup raw cashews or 1 cup cashew cream, 1 leaf bay, 8 sprigs fresh thyme, 7-8 cups vegetable stock

  • Bring the soup to a simmer and cook about 20 minutes or until the potatoes and carrots have softened. Stir in the nutritional yeast and turmeric at this point if using it. (If a chunky texture is preferred, reserve some of the cooked potatoes and gently mash them before adding back into the soup).

    1-2 tbsp nutritional yeast, 1/2 tsp turmeric

  • Carefully transfer the soup to a powerful blender and puree until smooth and creamy on the hot liquid setting. Work in batches if needed and be mindful of the escaping steam.

  • Adjust seasonings to taste with sea salt and black pepper then serve garnished with the reserved caramelized leeks, scallions, chives or fresh dill.(Optional: Finish with a drizzle of cashew cream if desired).

    sea salt + black pepper to taste, caramelized leeks, scallions, fresh chives + dill, chili flakes, chive blossoms, hemp seeds etc...

Slow Cooker Method:

  • Add all the soup ingredients except the herbs for garnish to a slow cooker and cook on low for 6-7 hours. Transfer to a blender and puree until smooth. Garnish with the reserved herbs and a drizzle of cashew cream.

Instant Pot Method:

  • Press the saute button on the Instant Pot and when the display reads hot add a splash of veggie stock and the leeks. Stir and cook until wilted and start to caramelize at the edges.

  • Add the carrots, potatoes, cashews, bay and thyme. Stir in the veggie stock. Put the lid on the pot and set the “ steam release “ knob to the “ sealing “ position.

  • Press the “ Pressure Cook or Manual “ button and the “ + - “ button to choose 8 minutes. Let the pot naturally release the pressure for 15 minutes then manually release the remaining steam.

  • When the pin in the lid drops you can open it and discard the bay leaf and thyme sprigs. Carefully transfer the soup to a blender together with the nutritional yeast if using and puree until smooth. Season to taste with sea salt and serve garnished with the fresh herbs.

WFPB + Plantricious

  • Omit oil and saute the leeks in a splash of water or veggie stock for compliance.

FAQs

Why does my leek and potato soup taste bitter? ›

Leeks, like onions, can become bitter if they're cooked for too long or at too high a heat. Make sure to sauté leeks over medium heat until they are soft and translucent, not browned. Another reason could be using the green parts of the leek, which are more fibrous and have a stronger flavor.

How do you make potato leek soup less bland? ›

If your soup tastes anything but super flavorful, you likely just need to add more salt! Toppings like fresh herbs (I like chives and thyme), croutons, bacon, or cheese help, but this soup should be flavorful on its own and salt should be the first thing you add if your soup tastes bland.

Why is my potato leek soup gummy? ›

Why is my potato leek soup gummy? Potatoes should be diced in similar size so they cook evenly, but don't drive yourself crazy getting them teeny-tiny. If they're too small, you risk the potatoes releasing too much starch, which can make the soup gummy when pureed.

How to thicken up leek and potato soup? ›

Add flour or cornflour

Put a tablespoon of either into a small bowl and stir in 2-3 tbsp of the soup until you have a smooth mixture. Stir this back into the soup and bring it to a simmer. Cook for a few minutes to allow the starch granules to burst to thicken, and to cook out any flour flavour.

How do you make potato soup not taste bland? ›

If a soup is tasting bland in the bowl, consider adding acid rather than salt. A squeeze of lemon or lime, or a dash of yogurt or sour cream can add brightness to the bowl.

How can I deepen my soup flavor? ›

"If your broth is lacking in savory richness, try adding roasted onion, tomato paste, mushrooms, seaweed, soy sauce, or miso. These ingredients add umami flavor and depth to broth," she says. The choice of ingredient depends on the recipe, though.

How do you keep potatoes from getting mushy in potato soup? ›

How do you keep potatoes from getting mushy in soup? Keeping the skins on your potatoes will help. Also key to remember is that when chopping the potatoes, the smaller they are the faster they will cook. So, don't be afraid to cut them a little on the larger side than you normally would.

How to stop leek and potato soup from going gloopy? ›

Potato-Leek Soup v2.

For an extra-smooth soup, press it through a chinois or a fine mesh strainer using the bottom of a ladle. Sure, it's the gluier than its pressed brother, but as I said, sometimes that really doesn't bother me.

What is the best thickening agent for potato soup? ›

Cornstarch is a very effective thickener, and a little bit can go a long way. Add cornstarch to a small amount of cold water or other liquid (wine or stock) and whisk into a thick slurry.

How do you blend potato soup without it being gummy? ›

FYI – with potatoes, you want to blend only as much as necessary to get a smooth texture. Blending them too long can make them gummy. Once all the soup is pureed you can pour it back into the pot and rewarm, or simply scoop and serve!

Why does my leek and potato soup taste bland? ›

Leek and potato soup needs a good tasty stock to start with, otherwise it is bland. I would not add water to it, as mentioned in the OP.

Why has my leek and potato soup gone brown? ›

It looks as though some of your potatoes might have got a bit scorched. Did you fry them off before adding the liquid? The colour from the browned potatoes could be what is turning it brown.

Will cream cheese thicken potato soup? ›

Cream cheese can be a delicious and tangy thickener for mashed potatoes so it stands to reason that it can also be used to add body to your favorite silky potato soup recipes — right? The answer is yes. It only works well if you do it carefully, though.

How do you fix bitter potato soup? ›

Sweetness can help balance bitterness, so consider adding ingredients like carrots, onions, or a small amount of sugar or honey. Acidic ingredients like tomatoes or a splash of vinegar can also help balance flavors.

How to get rid of bitter taste in potatoes? ›

You need to cut or scrap any green parts of the potato flesh or skin and discard those pieces. The other parts of the potato are usable. Because of this, it's important to store potatoes properly. A cool, not cold, dark and dry place is best.

How do you get the bitterness out of onion soup? ›

Soaking the onions in cold water for 10 minutes before cooking can help to reduce the unpleasant taste and smell. Additionally, adding a pinch of sugar to the cooking onions can also help to reduce their pungent flavor.
