Why You’ll Love This Vegan Potato and Leek Soup
This vegan potato leek soup slow cooker recipe is the definition of easy comfort food. It requires just a handful of simple ingredients, most of which you likely already have in your kitchen. Once everything is added to the slow cooker, the process is completely hands-off.
Slow cooking allows the flavors to develop gradually, creating a deeper, richer taste compared to quick stovetop methods. Many slow cooker soups rely on this “set it and forget it” approach, which makes them perfect for busy days.
This recipe is also naturally dairy-free, relying on ingredients like coconut milk and potatoes to create a creamy texture without the need for cream. Potatoes are often used in vegan soups to provide thickness and richness when blended, making them a staple in plant-based cooking.
Simple Ingredients, Big Flavor
One of the reasons this slow cooker vegan potato and leek soup works so well is its simplicity. The ingredients are straightforward but come together to create a comforting, flavorful dish.
Your base includes leeks, potatoes, onion, garlic, and vegetable broth, which are classic components of this type of soup. The addition of coconut milk adds richness and a smooth, creamy consistency without overpowering the flavor.
Herbs like thyme and coriander bring warmth and depth, while salt and pepper help balance everything out.
This combination of ingredients creates a soup that feels both hearty and light, making it perfect for lunch or dinner.
How to Clean Leeks
You need to clean leeks because they grow in sandy soil, and dirt gets trapped deep between their tightly layered leaves as they develop.
Unlike onions, which have a solid bulb, leeks are made up of many thin layers that can easily hold onto grit. Even if the outside looks clean, there’s often sand hidden inside. If you don’t wash them properly, that grit can end up in your dish—and it’s very noticeable (and unpleasant) when you bite into it.
Cleaning leeks ensures:
- Your food has a smooth, clean texture
- You avoid crunchy bits of dirt in soups or sautés
- The flavor stays fresh and not muddy
This is especially important in recipes like soups (like your potato and leek soup), where the leeks are a main ingredient and everything gets blended or cooked together.
It’s a small extra step, but it makes a big difference in the final dish.
First, cut the top and the bottom root part off. Only the white and light green sections are used. The dark green part can be saved and used for vegetable stock.
Cut the stalk in half lengthwise and slice into thin sections.
Fill a bowl with water and add the leeks. Swirl them around using your hands. Any dirt that is trapped will fall to the bottom of the bowl.
Next, scoop the leeks out using your hands and transfer to a colander. Don’t just pour the bowl into the colander- the dirt will come with it!
Now your leeks are ready to be cooked.
Slow Cooker Vegan Potato and Leek Soup
As with all things made in the slow cooker, this recipe couldn’t be easier! Once the leeks are properly cleaned and the potatoes are peeled and chopped, add all the ingredients to the slow cooker. Give it a stir and cook on low for 6 hours or until the potatoes are tender.
Once the soup has finished cooking, use an immersion blender to give it a creamy texture.
I topped mine with scallions, roasted chickpeas and salt and pepper.

How the Slow Cooker Makes It Even Easier
One of the biggest advantages of this recipe is the slow cooker. Instead of standing over the stove, you can simply add all your ingredients, turn it on, and let it do the work.
The slow cooker gently simmers the potatoes and leeks until they become soft and tender. Once cooked, blending the soup transforms it into a smooth, creamy texture with very little effort.
This method not only saves time but also enhances flavor. Slow cooking allows the ingredients to fully develop, resulting in a soup that tastes like it’s been carefully prepared, even though it requires minimal effort.

Tips for the Best Results
To get the best flavor and texture from your slow cooker vegan potato and leek soup, a few simple tips can make a big difference.
Make sure to clean your leeks thoroughly, as they often contain dirt between the layers. Using only the white and light green parts ensures a milder, more delicate flavor.
Choosing the right potatoes is also important. Russet or Yukon Gold potatoes work best because they break down easily and create a creamy consistency when blended .
Blending the soup at the end is what gives it that smooth, velvety texture. An immersion blender works best, but a standard blender can also be used if needed.
