This Vegan Potato Leek Soup Recipe relies on simple yet essential ingredients that truly shine. Each one plays an important role—from the crisp freshness of celery to the silky texture lent by cannellini beans—making this a well-rounded, flavorful dish that’s easy to put together with pantry staples.

Nondairy butter (6 tablespoons, divided): Adds rich creaminess and helps soften the leeks for a delightful base.
Leeks (4 cups, roughly chopped and washed): The star vegetable that brings a mild onion-like sweetness with every bite.
Garlic (3 cloves, finely minced): Boosts depth and warms up the flavor profile subtly but effectively.
Celery (1 cup, sliced): Introduces a light crunch and aromatic freshness to balance the potatoes.
Yukon gold potatoes (2 pounds, peeled and diced): Provide velvety texture and body, making the soup hearty and comforting.
Vegetable broth (6 cups): The flavorful liquid that brings everything to life with its savory undertones.
Cannellini beans (1 can, drained and rinsed): Add creamy protein and lend extra lusciousness when blended.
White wine vinegar (1 tablespoon): Offers a bright, tangy lift balancing out the richness perfectly.
Dijon mustard (1 tablespoon): Brings a subtle spicy tang that enhances depth without overpowering.
Kosher salt (1 ½ to 2 teaspoons) and black pepper (¼ teaspoon): Season the soup delicately to taste.
Chopped chives (¼ cup): Fresh and herbaceous finish to sprinkle on top before serving.

How to Make Vegan Potato Leek Soup Recipe

Step 1: Sauté the Leeks and Garlic

Start by melting 4 tablespoons of nondairy butter in a large soup pot over medium heat. Once the butter is melted and shimmering, add the chopped leeks along with the minced garlic. Stir everything to coat in the buttery goodness, then sauté for about 6 to 7 minutes until the leeks become soft and fragrant. This step unlocks the leeks’ natural sweetness and forms the aromatic base of our soup.

Step 2: Cook Vegetables with Seasoning

Next, stir in the sliced celery, diced potatoes, 1 ½ teaspoons of salt, and black pepper. Let the mixture cook for another 5 to 6 minutes, stirring occasionally. This step gives the vegetables a chance to meld their flavors before adding the broth, developing a richer taste and ensuring the celery is tender but still has a little bite.

Step 3: Add Broth, Beans, and Vinegar; Simmer

Pour in 6 cups of vegetable broth, then add the rinsed cannellini beans and a tablespoon of white wine vinegar. Give everything a good stir and bring it to a boil. Once boiling, reduce the heat to medium-low, cover the pot, and let it simmer gently for 30 minutes. This simmering slowly breaks down the potatoes and beans, allowing the flavors to deepen and the soup to become beautifully creamy when blended.

Step 4: Blend and Finish the Soup

Carefully transfer the hot soup in batches to a blender that’s safe for hot liquids. Add the tablespoon of Dijon mustard, then blend each batch until completely smooth and creamy. Pour the blended soup back into the pot, give it a taste, and add the remaining ½ teaspoon of salt if needed. Stir in the last 2 tablespoons of nondairy butter along with the chopped chives, then your soup is ready to serve!

Garnishes

Fresh chopped chives sprinkled on top not only bring a pop of vibrant green color but also add a subtle oniony flavor that brightens every spoonful. If you want to get fancy, a drizzle of good-quality olive oil or a dollop of vegan sour cream complements the smooth texture beautifully.

Side Dishes

This soup pairs wonderfully with crusty artisan bread, perfect for dipping into the creamy broth. A simple mixed greens salad with a light vinaigrette also balances out the richness of the soup and rounds out the meal with fresh crispness.

Creative Ways to Present

For a lovely presentation, serve the soup in rustic bowls with a sprinkle of freshly cracked black pepper and chives on top. You can also add roasted chickpeas or toasted pumpkin seeds for a crunchy contrast that makes this soup feel more festive and special.

Make Ahead and Storage

Storing Leftovers

After your meal, cool the soup completely before transferring it to airtight containers. Properly stored, this Vegan Potato Leek Soup Recipe keeps well in the refrigerator for up to 4 days, making it a great option for quick lunches or dinners during the week.

Freezing

This soup freezes beautifully! Pour cooled soup into freezer-safe containers or heavy-duty freezer bags, leaving some space for expansion. Frozen soup stays at its best for up to 3 months. When you’re ready, thaw overnight in the fridge for the smoothest texture.

Reheating

Reheat gently in a saucepan over low to medium heat, stirring occasionally to prevent sticking or scorching. You may want to add a splash of broth or water if the soup has thickened too much during storage, restoring that creamy consistency just like freshly made.

FAQs

Can I use other types of potatoes for this soup?

Absolutely! While Yukon gold potatoes are ideal for their buttery texture and flavor, you can substitute with red potatoes or even Russets. Just keep in mind that waxier potatoes will hold their shape a bit more, while Russets will create a fluffier, creamier soup.

Is it necessary to peel the potatoes?

Peeling the potatoes is recommended for a silky smooth texture, but if you prefer a more rustic soup with extra fiber, leaving the skin on works fine too. Just make sure to wash them thoroughly before dicing.

What if I don’t have a blender safe for hot liquids?

If you lack a heatproof blender, allow the soup to cool slightly before blending. Alternatively, you can use an immersion blender right in the pot, which is super convenient and helps you achieve a creamy texture without transferring hot liquids.

Can I make this soup spicier?

Definitely! Adding a pinch of smoked paprika, cayenne pepper, or even a few dashes of hot sauce while cooking can add warmth and depth. Just start small and adjust to your taste, so the delicate flavors of leek and potato still shine through.

Is there a way to make this soup thicker or thinner?

To thicken the soup, add a bit more potato or some soaked cashews if you want to keep it plant-based and creamy. For a thinner soup, simply add more vegetable broth or water until you reach your desired consistency.
