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.

I made this today, never having ever used leeks before. I have never been a fan of potato soup – they are usually the things I eat around and leave! But decided to give this a try… so glad I did! I shared it with my neighbors, who also loved it! I am sold!
The soup is smooth, flavorful and will be a go-to recipe I will make again and again. Thank you for this great recipe!
Wow, super delicious, and ridiculously easy!!! Thank you!!!
This potato leek soup recipe is excellent and easy. Good instructions, a small number of ingredients. And when I tell my guests they are eating “potage parmentier”, we all feel extra fancy. Thanks for sharing this great recipe.
Delicious!!!
Delicious recipe!
Absolutely delicious and so easy to make! This is a WINNER! I substituted olive oil for the
Butter, half and half for the heavy cream; and dried thyme for the fresh.
I did some substitutions to make this soup FODMAP friendly as well as vegan and I’m really pleased with how it turned out. I’m positive this recipe tastes incredible as is, but it was also AMAZING as a low-FODMAP vegan soup! Instead of butter and garlic, I used 3 Tbsp of garlic infused olive oil, instead of chicken broth I used my own low-FODMAP veggie broth, and instead of heavy cream I used full-fat canned coconut milk. Soooo delicious! Thank you, this is finally something hearty and comforting I can make that pleases my entire family.
Hi! Did the coconut milk give a coconut flavor or was it hidden? I’m out of cream. Thanks!
I used coconut cream and I don’t think it tasted different.
This is my family’s favorite soup recipe. I memorized it and make about 2 times a month no matter how hot it is outside. I also serve it with every holiday meal. I started to play with some extra ingredients by adding lemon thyme from my garden and lemon zest and lemon juice. That extra acidity gave it a nice zing! Potatoes + Leeks + Lemons= food bbfs =)
I substituted plain Greek yogurt for the heavy cream. It was excellent!
I found this recipe randomly, and it did not disappoint. I kind of went with following the process, but used random amount of vegetables. In addition to potatoes, I diced a bit of celeriac and one parsnip root, added them a few minutes before the potatoes and stock.
This site will be my go-to from now on. At least I don’t have to scroll forever to actually see the recipe.
Thank you! <3
Yes! The scrolling to get the recipe makes me go crazy.
This recipe is amazing! My husband wanted meat so I cut up and added some sauteed kielbasa to it. WONDERFUL! Definitely a repeat in our house!
