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.

Very good recipe! We loved it!
Leek soup does not have, has never had garlic. Additionally, it does not have thyme or bay leaves. This is your own recipe not the classic original recipe for Leek soup.
I have been enlightened to the point of boredom. But, just to waste your time, Karen, I mean Kathryn….by all means, share your recipe since you know so much about Leek Soup – even though, if you had been paying attention, the title is “Potato Leek Soup,” so, just maybe, “Potato Leek Soup” does actually have garlic, thyme, & bay leaves. I 100% believe this is her own recipe, as this is 100% her own website. Please get your own, & leave the cooking to this lovely lady.
LJ, you’re my HERO! 🙂
I don’t aspire to be a classical cook, just one that satisfies my family tastes.
I never realized there was only one “correct” way to make potato leek soup. We find this recipe to be delicious, correct or not! I would love to see the classic original recipe, can you send a link?
This is frustrating. I can’t find the list of ingredients showing amounts.
Hi Bronwyn, It sounds like you are just looking at the portion of the page that has the pictures with some instructions above. If you scroll down a bit to under the pictures, you’ll find the full recipe. Alternatively, at the very top of the page, to the right of the recipe name, you’ll see an orange/red button that says Jump to Recipe – if you click on that, it will take you directly to the recipe. Hope that clarifies!
I’ve made this recipe for a long time and love it. Its my go to recipe for Potato Leek, perfect, easy and has great taste. Sometimes I’ve used the Knorr chicken bouillon (trick I learned by a chef in Europe). It’s still as good and handy if you don’t have stock.
Used extra leek & extra stock, plus booster & garlic powder & lots more pepper. Served with crispy speck cubes on top. Solid recipe, thanks:)
such a tasty soup ! will be definitely doing it again 🙂
I was planning on making potato soup with dill until I came across this recipe; I bought two bundles of fresh dill and wondering if I could add in this recipe?? Or perhaps suggest another recipe?
Hi Anna, you can use some dill in this, but I’d limit it to 1 to 2 tablespoons.
I regretted adding the dill (added too much) but family liked it fine. I decided to retry your recipe again and stick to your recipe and it turned out AMAZING!! If I could give it 10* I would!! Thank you; I have signed up for your recipes and will stop searching elsewhere for recipes!!
Love your potato leak soup. It’s easy to make and very flavorful. I use whole milk and it’s still creamy enough.
Delicious! Out of bay leaves so used dash of dried basil (per Chef Google!). Finished with less cream and white pepper. And… drop of lemon juice. Divine!
Delicious! Added chives, bacon, cotija cheese and ground pepper.
What an unbelievably easy and delicious soup. I’m just amazed at how tasty this soup is. I can wait to share it with my family.
