A Silky Leek Soup Recipe

This creamy potato leek soup is a simple creamy classic for good reason!

  • Leeks have a mild and sweet onion flavor. They’re perfect in this soup as they don’t have an overpowering flavor.
  • Potatoes make this both hearty and budget-friendly while adding to the creamy base.
  • Serve this soup silky smooth by blending and straining through cheesecloth or leave it a little more rustic in texture by mashing the potatoes.
  • This potato leek soup makes a great lunch but it’s also elegant enough to serve as a starter soup to guests.

Ingredients for Potato Leek Soup

Leeks – Leeks look like a thick scallion (about 1 to 1 ½-inches thick). When buying, look for leaves that are firm, green, and upright. The greens are discarded as they’re tough.

Potatoes – We use Russet potatoes in this soup for their high starch content. Yellow or Yukon gold potatoes would also work! Potatoes should be peeled for this recipe.

Broth – Use either homemade chicken broth, vegetable stock, or use your favorite store-bought boxed broth. Heavy cream is added at the end for a bit of richness.

Variations – Sprinkle the final soup with some homemade bacon bits, or add a little fresh garlic to the soup. Add some crunchy parmesan croutons to the top for even more flavor!

How to Cut Leeks

If you haven’t used leeks in cooking, check out our guide on how to cut leeks. To prepare leeks for soup, keep the white to light green section and discard the dark green tops as they’re tough. Slice them in half and rinse out the grit in between the leaves. Slice thinly.

How to Make Potato Leek Soup

Nothing beats a warm, comforting, and creamy bowl of soup on a chilly day!

  1. Cook sliced leeks and celery in butter in a saucepan. Stir until softened.
  2. Add potatoes, broth, and seasonings to the pot and boil until potatoes are tender per the recipe below.
  3. Discard bay leaf, blend until smooth, and add a splash of cream. Simmer a couple of minutes more.

Top each bowl of soup with croutons, crumbled bacon, and some fresh herbs!

Feeling fancy? If serving this soup to guests, it can be strained through a fine mesh strainer or cheesecloth for a smoother soup. I usually don’t bother, I find blending is the perfect texture for our liking.

Tips for Blending Soup

If possible, a hand blender or immersion blender makes easy work of blending soups. Ensure the soup is deep enough that it completely covers the blades so it doesn’t splatter. If the soup is not deep enough, tilt the saucepan to the side to ensure that the blades are covered.

If you don’t have a hand blender, soup can be blended in a regular blender in batches. Ensure the lid isn’t sealed tightly or steam can build up and cause the blender lid to burst open causing a risk of injury.

Storing Potato Leek Soup

  • Potato leek soup will last in the refrigerator for up to 3 days.
  • To reheat, add to a pot on the stove and cook on medium heat until hot.
  • Unfortunately, creamy soups like this don’t freeze well as they end up becoming a little grainy when thawed. So eat it up!

Potato Leek Soup

Fragrant leeks are simmered with potatoes and burth until tender. Blend and add cream for a lovely elegant soup.
Prep Time 10 minutes
Cook Time 50 minutes
Total Time 1 hour
Servings 8 servings


Immersion Blender on white background
Immersion Blender or hand blender


  • 3 large leeks white only
  • 2 small ribs of celery ½-inch chopped
  • 1 stick butter (½ cup)
  • 2 pounds russet potatoes about 5 medium, peeled
  • 6 cups chicken broth or vegetable stock
  • 1 bay leaf
  • 3 sprigs fresh thyme or ½ teaspoon dried
  • salt and pepper to taste
  • 1 cup heavy cream
  • chives or thyme for garnish


  • Cut off the green of the leeks and discard (or freeze for stock). Cut the leeks lengthwise and wash well to remove any dirt or grit.
  • Thinly slice the whites of the leeks, about 5-6 cups.
  • Place leeks, celery, and butter in a large pot. Cook over medium heat until leeks are tender without browning them, about 5-7 minutes.
  • Cut potatoes into large chunks and add to the pot with broth, thyme, bay leaf, and salt & pepper to taste. Simmer, covered, for 45 minutes or until potatoes are tender.
  • Discard bay leaf. Using an immersion or hand blender*, blend soup until smooth. Add cream and simmer for 2-3 minutes. Season with salt and pepper if needed.


Optional: Once blended, run through a strainer lined with cheesecloth to achieve a smoother texture.
Leftover soup can be stored in the fridge in an airtight container for up to 3 days. Reheat on the stovetop or in the microwave. 
Because of the cream, this soup does not freeze well. (It will become grainy when thawed.)

  1. I’m making this wonderful soup again. To this day, I haven’t been able to find an alternate recipe and I did tried others. Like other times I make this potage, it will not last long as everyone in the family wants some. Highly recommended.

    1. As an addendum to the note by Holly: I do often freeze this soup but without the cream. It will be lumpy when thawed but whisked it, whisked good when reheating on the stove top and it will eventually come back as smooth as Tennessee whisky. Add cream to individual portions.5 stars

  2. My grandmother and mother used to make a variation on this recipe, in our house it was called Winter Vichyssoise. Because, of course, Vichyssoise is served cold, but this is served warm. I need to find my mom’s hand-written recipe box to see if there is any difference between her version and yours. I do remember her blending it, a few cupfuls at a time until it was smooth, and I think she didn’t put cream in it, maybe skim milk (that was all we ever had in the house, even back in the 50sand 60s). I suspect she may have added a little extra chicken stock to thin it down, but I also remember it being a favorite dinner served with buttered toast and home canned green beans on the side.

  3. Made this tonite my family loved it! I’ve sent it to a few friends, will make it again! Used 18% cream delicious.5 stars

  4. Perfection! Such a delicious and subtle flavour Holly. I like a very smooth vichyssoise so used a hand blender first and then transferred to my large Osterizer blender. It was quite thick so I just adjusted the consistency by adding more stock before the cream and it’s delicious. I sprinkled a bit of crumbled blue cheese on top and will definitely be making this again. Thanks for sharing!5 stars

  5. I was so excited to make this recipe. Could not find when to add the thyme sprigs listed first , before the ones listed for garnish. I added them when I added the potatoes. Quite tasteless. Very mediocre.2 stars

    1. Hi Robert, you can freeze this soup but it freezes best before adding the cream!

  6. I’m making this soup often and will continue to make it often. It is delicious. Thank you for the recipe.
    BTW, what< size portion is used for the nutrition information?5 stars

    1. A serving size is about 1 to 1 1/2 cups depending on the size of your potatoes and leeks used.

  7. Delicious soup, and simple to make. I assumed the three sprigs of thyme wen into the pot with the potatoes. I just threw them in intact, as most of the leaves will come off during cooking and then fished out the branches before pureeing. Thanks for a great recipe!5 stars

  8. Holly…..please help! I do not know what I did wrong. The soup came out awful. This was a real moment of defeat as I am an accomplished cook and baker. I followed your recipe to a “t”. I’ve been agonizing over this all night. Should I add bacon? Should I add chives & cheese? Some other kind of spice? Please tell me what to do.
    Thank you,
    Ruth2 stars

    1. So sorry to hear that Ruth, that is not good! While I don’t think you can ever go wrong with more bacon was there something specific that didn’t work out for you?

    1. Yes, this soup can be frozen. While it freezes well in any case, it’s best if frozen before adding the cream.

  9. Do you cut or cube the potatoes after you peel them to put them into the soup or do you leave them whole? I can not wait to try this recipe!

    1. Hi Janet, this recipe is a delicious potato leek soup option! For the full recipe, you can scroll to the bottom of the post or use the “jump to recipe” button at the top.

  10. Delicious!! My husband and I loved this! We substituted the butter and cream for vegan friendly options and it turned out so good! Definitely keeping this in the cook book :) Thank you for sharing!5 stars

  11. I made the potato leek soup and it was spectacular. It was easy to make, just follow all the steps properly. Can’t wait to make again5 stars

  12. Hi when you say cups of something in your recipe how big should the cup be. Also when you say a stick of butter is 5hat a whole block of butter?
