The backstory.

This recipe was born out of a little leftover magic. After making a spring veggie tart, I found myself with half a bundle of leeks that were too good to waste. So I reached for pantry staples and turned them into something warm and satisfying. This leek and potato soup is proof that a humble handful of ingredients can make a nourishing bowl that feels like a hug from the inside out.

It's a must-make.

This vegan potato leek soup is the kind of recipe that surprises everyone, in the best way:

  • Creamy without dairy. Blended potatoes and a swirl of vegan sour cream make it rich and velvety.
  • Big flavor, minimal effort. A splash of white wine and vinegar plus fresh herbs bring bold flavor with barely any work.
  • Perfect meal prep. It keeps well and tastes even better the next day.
  • Endlessly customizable. Add beans, greens or a little spice to match your pantry and your cravings.

From fridge afterthought to feel-good favorite.

Let’s talk texture and flavor.

The first spoonful hits you with a silky, rich texture from the blended russet and sweet potatoes. Then comes the mellow sweetness of the leeks, earthy thyme and just the right tang from white wine vinegar and vegan sour cream. It’s cozy, balanced and lusciously smooth, a more wholesome cousin to classic potato soup.

What you'll need.

Here’s what you’re going to need to make this cozy, creamy vegan potato leek soup:

  • Leeks – use the white and light green parts, and rinse them well since they like to hide dirt.
  • Carrots and celery – the classic soup base.
  • Russet and sweet potatoes – russets make it creamy, sweet potatoes add a subtle sweetness.
  • Vegan butter or olive oil – for sautéing the vegetables.
  • Vegetable stock – the base of the soup.
  • Dry white wine – adds depth. More broth and a squeeze of lemon works too.
  • Fresh thyme and bay leaves – infuse the broth with cozy, woodsy flavor.
  • Kosher salt and black pepper – to season.
  • White wine vinegar – a bright finish. Lemon juice works too.
  • Chives and vegan sour cream – for a silky, fresh finish.

Customize it your way.

Customize this leek and potato soup to match your taste or what’s in your fridge:

  • White beans for extra protein – stir in a can of drained white beans to make it more filling.
  • Spinach or kale – toss in a handful of greens during the last few minutes of cooking.
  • Coconut milk – add a splash of coconut milk or coconut cream for an ultra-rich texture.
  • Red pepper flakes – a pinch brings a little warming heat.
  • Yukon gold potatoes – swap some in for a buttery flavor and slightly different texture.

Flexible dietary swaps.

Want to make it your way? Here are some easy swaps for this vegan potato soup:

  • No wine – use more vegetable broth with a splash of lemon juice.
  • No vegan sour cream – use cashew cream, vegan yogurt or coconut cream.
  • Extra plant protein – toss in cubes of tofu, white beans or chickpeas.
  • Not vegan – regular butter and dairy sour cream work just as well.
  • Low sodium – use low-sodium broth, reduce the added salt and boost the flavor with extra herbs, garlic or lemon.

How to make vegan leek potato soup.

This one-pot wonder is easy, breezy and super satisfying. Here’s how to make it:

Sauté

Heat the butter or oil in a soup pot, add the leeks, celery and carrots, and cook until softened.

Simmer

Add the potatoes, stock, wine, salt, pepper and herbs. Bring to a boil, then simmer until the potatoes are tender.

Blend

Remove the bay leaves and blend half the soup until smooth. A regular blender gives you the most control.

Finish and serve

Return the blended soup to the pot, stir in the white wine vinegar, chives and vegan sour cream, and adjust the seasoning.

How to serve it.

Creamy, comforting and totally customizable. Enjoy it on its own or topped to your heart’s content:

  • Finish with a swirl of coconut cream or vegan sour cream.
  • Top with crispy croutons or roasted chickpeas.
  • Serve with fresh crusty bread or toasted sourdough.
  • Pair with a fresh green salad for a hearty lunch.
  • Meal prep it for make-ahead lunches. It’s freezer-friendly too!
  • Make it flex – stir in shredded rotisserie chicken or top each bowl with crumbled crispy bacon.

Kori's tips.

  • Clean your leeks well. Nothing is worse than crunching on a bit of dirt in your soup.
  • The mix of russet and sweet potatoes gives the creamiest texture and a subtle sweetness.
  • For a smoother soup, blend the whole pot. For a bit of texture, blend only half.
  • This soup tastes even better the next day, so it’s great for leftovers and meal prep.

FAQs

How do you store vegan potato leek soup?

Store it in an airtight container in the fridge for up to 5 days.

Can I freeze potato leek soup?

Yes. It freezes beautifully. Cool it completely, then freeze it in portions.

How do I reheat it?

Reheat it in a microwave-safe bowl in 1-minute bursts, stirring in between, or warm it in a pot over medium heat, stirring occasionally.

How do you clean leeks?

Trim off the root and dark green tops, slice the leeks in half lengthwise and then into slices. Soak them in a bowl of cold water, swish them around, and lift them out so the dirt stays at the bottom.

Ingredients
  

  • 2 tablespoons vegan butter or olive oil
  • 16 ounces leeks (white and light green parts, cleaned and sliced)
  • ¾ cup carrots (diced)
  • ¾ cup celery (diced)
  • 1 pound russet potatoes (peeled and ½" diced)
  • ½ pound sweet potatoes (peeled and ½" diced)
  • 48 ounces vegetable stock
  • ½ cup dry white wine
  • 2 teaspoons fresh thyme leaves (chopped)
  • 2 bay leaves
  • 1½ teaspoons kosher salt
  • ½ teaspoon ground black pepper
  • 3 tablespoons white wine vinegar (lemon juice may be substituted)
  • ¼ cup chives (finely chopped)
  • ½ to 1 cup vegan sour cream (start with ½ cup and add to taste)

Instructions
 

  • Heat the vegan butter or oil in a soup pot over medium heat. Add the leeks, celery and carrots. Cover and sweat the vegetables until softened, stirring occasionally, about 5 to 8 minutes.
  • Add the potatoes, stock, wine, salt, pepper, thyme and bay leaves. Bring to a boil, then reduce the heat, cover and simmer for 20 to 25 minutes, until the potatoes are fork tender.
  • Remove the bay leaves. Spoon about half of the soup into a blender and blend until smooth. (You can also use an immersion blender, but a regular blender gives you more control if you like some chunky bits.)
  • Return the blended soup to the pot and stir in the white wine vinegar, chives and vegan sour cream. Warm if needed, adjust the seasoning to taste and serve.

Kori's Tips

For more helpful hints, substitution ideas, cooking tips, and other delicious recipes check out my post above.
TIPS: Use the white and light green parts of the leeks. Slice them in half lengthwise, then into slices, and soak them in water to rinse out any hidden dirt. Blend the whole pot for an extra creamy soup, or just half for a chunkier texture. It tastes even better the next day.
VARIATIONS: No wine? Use more broth and a squeeze of lemon juice. No vegan sour cream? Use cashew cream, vegan yogurt or coconut cream, and adjust the tang with a little extra vinegar. Stir in white beans for protein or a handful of spinach for extra greens.
MAKE IT FLEX: Use chicken broth and stir in shredded rotisserie chicken, or top each bowl with crumbled crispy bacon.
MEAL PREP: This soup is great for make-ahead lunches. It keeps in the fridge for up to 5 days and freezes beautifully.
SERVING SUGGESTIONS: Garnish with chives, extra vegan sour cream and black pepper. Top with croutons or roasted chickpeas, and serve with crusty bread or a lemony green salad.
