What is Creamy Potato and Leek Soup?

Creamy potato and leek soup is a French-inspired classic that’s been comforting families for generations. At its core, it’s a blend of tender starchy potatoes and mild leeks—those long, green, onion-like veggies that bring a subtle sweetness when sautéed. What makes it truly stand out is the smooth, rich consistency that comes from blending the cooked veggies with a little cream (or a lot, if it’s been a week).

It’s traditionally served hot, though it can be chilled and served as Vichyssoise if you’re feeling fancy. But for most of us? We’re reaching for this when it’s soup season and we want something hearty but not heavy. It’s versatile, it’s budget-friendly, and the flavor somehow deepens every time you reheat it. Honestly, it’s one of those recipes that feels like it should be complicated—but thankfully, it’s not.

Reasons to Try Creamy Potato and Leek Soup

So, why should creamy potato and leek soup be next on your meal plan? First off, it’s incredibly easy to make, even if you’re not exactly Julia Child. Everything happens in one pot, which means less cleanup and more time for whatever you actually want to do after dinner. Second, it’s adaptable—you can make it vegetarian, vegan, or sneak in some crispy bacon on top if you’re living that meat-lover life. And third, it’s just downright comforting.

We’re talking curl-up-on-the-couch-with-a-blanket comfort. Also, if you’ve got leftover leeks or potatoes lurking in your fridge, this is your chance to save them from a slow and silent demise in the crisper drawer. Finally, it stores beautifully, so go ahead and make a big batch. You’ll thank yourself later.

Instructions to Make Creamy Potato and Leek Soup

Making this creamy potato and leek soup is easier than you might think. Follow this step-by-step guide to bring out the best flavors and textures while keeping your kitchen stress-free. Whether you’re a first-time soup maker or a seasoned home cook, these expanded instructions will walk you through everything you need with helpful tips and suggestions along the way.

Step 1: Clean and Prep the Leeks

Leeks can be sneaky little dirt magnets, so this first step is key. Start by trimming off the root end and the dark green tops (you can save those for making homemade broth if you’re feeling thrifty). Slice the white and light green parts lengthwise, then fan them out and rinse thoroughly under cold water to remove any grit hiding between the layers.

Once clean, slice the leeks into thin half-moons. This prep might feel a bit tedious, but trust me—it makes a huge difference in your soup’s texture and flavor.

Step 2: Sauté the Aromatics

In a large soup pot or Dutch oven, heat 2 tablespoons of unsalted butter and 1 tablespoon of olive oil over medium heat. This fat duo adds depth and richness from the start.

Add the diced onion and cook for about 5–7 minutes until it becomes soft and translucent—don’t rush this part, as it’s the foundation of your soup’s flavor. Then stir in the minced garlic and prepared leeks. Continue cooking for another 8–10 minutes. The leeks should soften and become fragrant without browning. Stir occasionally to prevent sticking.

This step-by-step sauté process develops a mellow, savory base and gives the leeks their signature buttery texture.

Step 3: Add Potatoes, Herbs, and Broth

Now it’s time to bulk things up. Toss in your peeled and diced starchy potatoes (Russets or Yukon Golds are ideal). Add two sprigs of fresh thyme and a bay leaf—these herbs infuse the broth with subtle earthy notes that round out the soup’s creamy vibe.

Season with a pinch of salt and black pepper. Then pour in 6 cups of low-sodium vegetable broth (or chicken broth if you’re not vegetarian). Want to learn how to make your own broth from scraps? Head over to our homemade broth tips for ideas that save money and reduce food waste.

Bring everything to a gentle boil, then reduce the heat to low. Cover and simmer for 20–25 minutes, or until the potatoes are fork-tender. Stir occasionally to prevent sticking on the bottom of the pot.

Step 4: Blend to Creamy Perfection

Once your potatoes are tender, it’s time to blend. But first—remove the bay leaf and thyme sprigs. Nobody wants to bite into a twig.

Using an immersion blender, blend the soup directly in the pot until it reaches a smooth, velvety consistency. If you don’t have an immersion blender, no worries! Carefully transfer the soup to a regular blender in batches. Be sure to vent the lid slightly to avoid pressure build-up from the steam—hot soup has a rebellious streak.

Step 5: Stir in the Cream

With your soup now silky and dreamy, return the pot to low heat. Gently stir in 1 cup of heavy cream and let it warm through. Don’t let it boil—cream is sensitive and could curdle if pushed too far.

If you’re dairy-free or cutting back, try swapping in full-fat coconut milk or cashew cream. For a lighter version, half-and-half works beautifully too. We’ve got a few clever swaps listed in our nourishing turmeric golden soup if you’re looking to lighten things up without losing that cozy richness.

Taste and adjust seasoning as needed. A pinch more salt or a crank of pepper could be the final touch your soup needs.

Step 6: Garnish and Serve

Now for the fun part—ladling your steaming, creamy potato and leek soup into bowls and dressing it up. Top with chopped fresh parsley, snipped chives, croutons, a swirl of cream, crispy bacon bits, or even grated cheese if you’re feeling indulgent.

For a full meal idea, try pairing it with our herbed potato rolls or a bright contrast like this apple and feta salad. It’s a whole vibe.

And just like that, your step-by-step creamy potato and leek soup is ready to impress. Whether it’s a quiet night at home or your contribution to a family dinner, this soup shows up and delivers warmth in every spoonful.

What to Serve with Creamy Potato and Leek Soup

This soup is a full-on comfort meal, but pairing it with something crunchy or fresh really brings it to life. A hunk of crusty sourdough bread is a no-brainer. Garlic toast? Yes please. If you want something a bit more green, try a light salad like our Autumn Harvest Honeycrisp Apple and Feta Salad. For a heartier option, add a side of herbed potato rolls—they’re dreamy dipped into the soup. And if you’re leaning into the soup-and-salad cafe lunch vibe, go all in.

Key Tips for Making Creamy Potato and Leek Soup

Clean your leeks like your soup depends on it—because it does. Nothing ruins a cozy vibe faster than gritty broth. Choose starchy potatoes for that creamy texture without needing a roux. Don’t rush the sauté step; those onions and leeks need time to get sweet and soft. When blending, work in batches if needed and always be cautious with hot liquids. For a lighter version, swap cream for half-and-half or go dairy-free with full-fat coconut milk. And hey, taste as you go. Salt can make or break a soup. Little tweaks can turn a good soup into a “wow, I made that?” moment.

Storage and Reheating Tips for Creamy Potato and Leek Soup

Got leftovers? Lucky you. Store your soup in an airtight container in the fridge for up to 4 days. It also freezes beautifully—just leave out the cream before freezing and add it when reheating. To reheat, warm gently on the stovetop over low heat, stirring frequently. If it’s too thick, add a splash of broth or milk. Microwave works too, just go in short bursts and stir in between. Avoid bringing it to a boil after the cream’s in—nobody wants split soup. If you batch-cook for busy weeks, this one’s a freezer MVP.

Yes, but it’ll be less rich. Half-and-half is a good middle ground.

Is this soup gluten-free?
Totally! No flour needed—just blend those potatoes until smooth.

Can I make it vegan?
You bet. Use olive oil instead of butter and full-fat coconut milk instead of cream.

What if I don’t have leeks?
Sub in mild onions or shallots, but the flavor won’t be quite the same.

Add a pinch of cayenne or crushed red pepper flakes when sautéing the leeks.
