This French classic, known as Potato Leek Soup when served hot and Vichyssoise when chilled, is simplicity and elegance in one pot.

Whether you’re craving a rustic version with chunks of potatoes or a smooth and silky puree, this recipe gives you both options.

What Makes Potato Leek Soup So Special?

There’s a reason why potato leek soup remains one of the most beloved classics in French-inspired home cooking.

How to Make Potato Leek Soup: Step by Step

Step 1: Preparing the Potatoes

Start with a couple of russet potatoes. These are ideal because their high starch content creates a creamy consistency once cooked and blended.

Peel the potatoes using a vegetable peeler. Here’s a cool tip: that little loop on the side of your peeler? It’s actually designed to scoop out the “eyes” of the potatoes! Many people miss this handy feature.

Once peeled (or scrubbed clean, if you’re leaving the skins on for a rustic texture), slice the potatoes in half lengthwise, then chop them into rough chunks. Don’t worry about perfection here; they’ll soften and blend later. Set the chopped potatoes aside for now.

Step 2: Cleaning and Slicing the Leeks

Leeks are flavorful but notorious for hiding sand and grit between their layers. Take the time to clean them properly:

1. Trim off the dark green tops and root ends. (Save the greens to make stock later.)
2. Cut the leeks in half lengthwise.
3. Peel away and discard any tough outer layers.
4. Rinse the leeks under cold running water, separating the layers gently to remove all the dirt.

Slice the clean leeks thinly into half-moon shapes. Aim for 3 large leeks or about 2 heaping cups of sliced leeks. You’ll use mostly the white and pale green parts, which are the most tender and flavorful.

Step 3: Sautéing the Leeks in Butter and Olive Oil

Place a large soup pot or Dutch oven over medium heat. Add about 3 tablespoons of butter and a drizzle of olive oil. The oil helps prevent the butter from browning too quickly.

When the butter starts to bubble and pop, it’s almost ready. If the moisture evaporates too quickly, the butter will brown, which adds a nutty flavor you don’t want in this delicate soup.

Add in your sliced leeks. Sprinkle a pinch of salt and a dash of white pepper. White pepper keeps the soup looking pale and elegant (unlike black specks from black pepper).

Simmer the leeks, stirring regularly. You’re aiming to sweat them, which means softening them without browning. Let them turn soft, silky, and translucent. This step builds the mellow, sweet base of your soup.

Step 4: Adding Garlic and Potatoes

Next, toss in your garlic. Use about 3–4 cloves, smashed with the side of your knife. No need to mince since you’ll blend the soup later, rough is fine.

Stir in the chopped potatoes, mixing them into the buttery leeks and garlic. Let them cook for a minute or two to absorb some flavor.

At this point, your kitchen should smell lovely, garlicky leeks with creamy potatoes soaking up the flavor.

Step 5: Simmering in Stock

Now, pour in your chicken stock or vegetable broth. Use about 3 cups. If you’re using Better Than Bouillon or a similar concentrate, mix it with warm water first and then add it to the pot.

Bring the mixture to a gentle simmer. Cover the pot partially and let everything cook for about 10–15 minutes, or until the potatoes are fork-tender.

Test for doneness by piercing a potato chunk with a skewer or cake tester. It should go through without resistance. At this point, all the flavors will have started to mingle beautifully.

Step 6: Adding Cream and Finishing Touches

Once your potatoes are fully tender, turn off the heat and stir in 1 cup of heavy cream.

Wait until the end to add cream; this prevents it from curdling or boiling over. If you want a lighter version, you can use whole milk or even half-and-half, but heavy cream gives it that luxurious texture.

Add a pinch of freshly grated nutmeg at this stage. It brings out the earthy sweetness of the potatoes and adds just a hint of spice without overpowering the dish.

You can also add a bay leaf during the simmering phase for extra depth, though it’s optional.

Step 7: Blend or Mash – Two Texture Options

Now, you get to choose your adventure. Do you want a rustic soup with texture or a silky-smooth puree?

Option 1: Rustic and Chunky

Use a potato masher directly in the pot. Mash until you reach a thick, chunky consistency. This version feels heartier and is perfect if you enjoy the natural texture of the ingredients.

You can serve it with a splash of cream on top or a drizzle of olive oil for a refined finish.

Option 2: Silky and Smooth

Use an immersion blender or transfer the soup in batches to a countertop blender. Blend until smooth and creamy.

Be careful not to over-blend, especially in a food processor. Too much agitation can release potato starch, making your soup gluey. As long as there’s enough liquid, you’ll avoid that sticky texture.

Step 8: Adjust Seasoning and Texture

Once blended, give your soup a taste test. Add more salt, white pepper, or even a splash of extra cream if it feels too thick or bland.

The flavors may seem mild now, but remember: if you plan to eat the soup cold, you’ll want to season it slightly more aggressively. Cold temperatures dull flavor perception, so a bit of extra salt and nutmeg can make a big difference.

If your soup feels too thick, thin it out with a little warm broth or water.

For extra richness, you can also blend in a tablespoon or two of cold butter, a trick used in many restaurant kitchens.

Step 9: Serving the Soup

Ladle the finished soup into bowls. For the best presentation and flavor, top it off with any of the following:

• A sprinkle of freshly chopped chives
• A drizzle of olive oil or swirl of cream
• A touch more grated nutmeg for aroma

Serve alongside crusty bread, toasted baguette slices, or even garlic bread. The contrast of crisp bread and creamy soup is just perfect.

Step 10: Enjoy It Hot or Cold

Here’s the best part: this soup is delicious hot or cold.

• When hot, it’s hearty and comforting, ideal for cozy evenings, especially in the colder months.
• When cold, it transforms into Vichyssoise, an elegant, refreshing dish served chilled, perfect for summer lunches or as a starter for dinner parties.

If serving it cold, let it chill in the fridge for several hours (or overnight) in an airtight container. The texture thickens slightly when cold, and the flavors mellow, which is why re-seasoning before serving is often needed.

Tips for the Perfect Potato Leek Soup

Creating the perfect potato leek soup is all about technique and timing. Each step contributes to that silky texture and balanced flavor that make this dish irresistible.

1. Use the Right Potatoes: Russets or Yukon Golds are ideal for creaminess. Russets give a smooth texture, while Yukon Golds add a buttery taste.
2. Clean Leeks Thoroughly: Leeks trap dirt easily, so rinse between every layer to prevent a gritty soup.
3. Don’t Brown the Leeks: Cook them gently in butter and oil until soft and translucent. Browning adds unwanted bitterness.
4. Add Cream Last: Always stir in cream or milk after the soup has simmered. Adding dairy too early risks curdling.
5. Blend Carefully: Use an immersion blender for a smooth texture. Over-blending can make the soup gummy due to potato starch.
6. Season with White Pepper: It maintains the soup’s pale color and adds mild heat.
7. Finish with Nutmeg or Chives: Freshly grated nutmeg enhances depth, while chopped chives add freshness.
8. Taste Before Serving Cold: If chilling your soup, re-season before serving cold foods, as they need extra salt to taste balanced.

With these techniques, you’ll achieve a beautifully balanced soup, creamy, flavorful, and full of French-inspired comfort.

Perfect Pairings

Potato-leek soup pairs well with a variety of sides and accompaniments that enhance its mild, creamy flavor. Whether you’re serving it as a starter or a main course, these combinations make each meal feel complete and comforting.

• Crusty Artisan Bread: The crisp exterior and chewy interior are perfect for dipping into the creamy soup.
• Garlic Butter Baguette: Adds richness and a touch of indulgence to every bite.
• Simple Garden Salad: A fresh mix of greens with a tangy vinaigrette balances the soup’s smooth texture.
• Grilled Cheese Sandwich: A classic comfort pairing that turns this soup into a hearty meal.
• Roasted Vegetables: Carrots, asparagus, or brussels sprouts bring color and a caramelized contrast.
• Smoked Salmon Toast: A sophisticated pairing for chilled Vichyssoise, adding salty depth.
• White Wine: Serve with Sauvignon Blanc or Chardonnay; their acidity cuts through the creaminess beautifully.
• Crumbled Bacon or Crispy Shallots: Sprinkle on top for a salty, crunchy finish that elevates both flavor and presentation.

Together, these pairings transform your bowl of potato leek soup into an unforgettable, restaurant-worthy experience.
