Cozy up with this comforting potato leek soup, a classic French dish that’s easy to make and endlessly customizable.
Potato leek soup, or potage parmentier, is a French classic. It’s one of the first dishes I learned to make in culinary school, right after a proper omelette and basic vinaigrette, because it’s an essential base soup in French cuisine. You can add watercress to make potage au cresson, serve it chilled as Vichyssoise, or top it with bacon, fried leeks, fresh herbs, or diced vegetables. There are endless variations—just use your imagination (or whatever you have in the kitchen) to make it your own. This potato leek soup recipe is simple to whip up and can be served as an appetizer, paired with a Reuben sandwich or wedge salad, or enjoyed as a satisfying lunch on its own.
What You’ll Need To Make Potato Leek Soup
Step-by-Step Instructions
Potato leek soup is simple to make, but first you have to deal with the leeks. They’re notoriously sandy and dirty, and very good at hiding it, so be sure to wash them well. Start by cutting off and discarding the root ends and thick dark green parts. Cut the leeks in half lengthwise and rinse each half under cold water, pulling apart the layers to remove any grit that’s tucked inside.
Once the leeks are clean, roughly chop them — you should get about five cups of chopped leeks from four large leeks.
To make the soup, melt the butter in a Dutch oven or large soup pot, then add the chopped leeks and garlic.
Cook, stirring occasionally, until soft and wilted.
Next, add the potatoes, chicken broth, bay leaves, thyme, salt and pepper.
Bring to a boil.
Then cover, reduce the heat, and simmer for 15 minutes, or until the potatoes are tender.
Fish out the bay leaves and thyme sprigs.
Purée the soup with a hand-held immersion blender (or in a regular blender) until smooth. (If using a standard blender, be sure not to fill the jar more than halfway; leave the hole in the lid open and cover loosely with a dishtowel to allow the heat to escape.)
Finally, add the heavy cream. You can reduce the amount if you’d like but I wouldn’t leave it out entirely. Cream makes the soup deliciously silky, rich, and smooth—just add it little by little until the soup tastes good to you.
Bring to a simmer, then taste and adjust the seasoning with salt and pepper. Serve hot, garnished with fresh thyme, chives, or anything you like.

Cozy up with this comforting potato leek soup, a classic French dish that’s easy to make and endlessly customizable.
Ingredients
- 3 tablespoons unsalted butter
- 4 large leeks, white and light green parts only, roughly chopped (about 5 cups)
- 3 cloves garlic, peeled and smashed
- 2 pounds Yukon Gold potatoes, peeled and roughly chopped into ½-inch pieces
- 7 cups chicken or vegetable broth
- 2 bay leaves
- 3 sprigs fresh thyme
- 1 teaspoon salt
- ¼ teaspoon ground black pepper
- 1 cup heavy cream
- Chives, finely chopped, for serving
Instructions
- Melt the butter over medium heat in a large soup pot. Add the leeks and garlic and cook, stirring regularly, until soft and wilted, about 10 minutes. Adjust the heat as necessary so as not to brown.
- Add the potatoes, broth, bay leaves, thyme, salt and pepper to pot and bring to a boil. Cover and turn the heat down to low. Simmer for 15 minutes, or until the potatoes are very soft.
- Fish out the thyme sprig and bay leaves, then purée the soup with a hand-held immersion blender until smooth. (Alternatively, use a standard blender to purée the soup in batches; see note.) Add the heavy cream and bring to a simmer. Taste and adjust seasoning with salt and pepper. If soup is too thin, simmer until thickened. If it's too thick, add water or stock to thin it out. Garnish with fresh herbs if desired.
- Note: If using a standard blender to purée the soup: be sure not to fill the jar more than halfway; leave the hole in the lid open and cover loosely with a dishtowel to allow the heat to escape; and pour blended soup into a clean pot.
- Freezer-Friendly Instructions: The soup can be frozen, without the cream, for up to 3 months. Defrost the soup in the refrigerator for 12 hours and then reheat it on the stovetop over medium heat until hot. Once heated through, add the cream and bring to a simmer before serving.

Simple and delicious recipe! This is my first time cooking with leeks and won’t be my last 🙂
Excellent every time
Do you think I could use white sweet potatoes in this soup?
I think it will have a different taste, but that it should work. Please LMK how it turns out if you try it!
I made it in my foodi but added carrots and left out the cream…it’s more of a thick potato soup with hints of leek. We plan to add chopped smoked grilled pork belly as a topper. Yum.
That soup deserves expletives. So easy and amazing. I used a full stack of thyme, reds and Yukons, skin on, and the blender.
Many fans, including children. Yes!
Thank you!
Made this soup for the first time and was a huge hit- husband and 2 year old daughter. I used russet potatoes because that’s what I had on hand and worked just fine. Also crisped up some bacon and used as a garnish when served. Super easy and delicious recipe, a keeper for sure!
Soup turned out fantastic, I added a little tarragon because we love the flavour. Making another pot full for a luncheon today
I love this one in the fall when leeks are coming out of the garden. It’s easy to make, and everyone I’ve shared it with loves it.
I love this potato leek soup — I wouldnt change a thing. The receipe was easy and perfect!
This soup is fantastic as written. My 1st experience cooking with leeks. I was not disappointed.
Thanks for a great recipe!
I made the soup a day before having company for dinner tomorrow. We found it a bit bland (made exactly as listed) but a nice comfort soup. I actually like it better without the cream so when I serve it tomorrow I’m going to top with a bit of cheese, chives and crumbled bacon with a salad and crusty bread.
Delicious soup!!! Just like the potato leek my husband and I enjoyed in the pubs in Ireland during our honeymoon. How many days would you say the leftovers are good for when stored in the fridge? Thank you!!
So glad you liked it! You can refrigerate the leftovers for 3 or 4 days. For longer storage, you can freeze it. It’s best to freeze the soup without the cream, but if you already have the cream in it, it may separate a little when you reheat it. Just give it a few stirs to recombine.
