Creamy Potato & Leek Soup

A handful of years ago I was at a wedding that served a Cream of Potato & Leek soup as part of the meal. It’s one of the most memorable food items I’ve ever had at a wedding… maybe the most memorable. It was delicious – thick and hearty, creamy, and full of flavor. The leeks imparted a mellow flavor reminiscent of an onion, but not nearly as strong or overpowering, and the taste of potato really shined through. I’ve been dreaming of that soup ever since, and keep making mental notes to look for a recipe so I could try to recreate it. Well, it’s been almost five years, so I’d say that my statute of limitations was almost up, and I finally hunkered down to make a version of cream of potato and leek soup. It’s just as delicious as I remember it, and I love that I can now have it anytime at home, without being reduced to just daydreaming about it!
Of all the potato and leek soup recipes that I found I loved this one most for two reasons:
#1: It is creamy; and
#2: There is not any cream in the recipe.
Save This Recipe
Sounds like a contradiction, doesn’t it? The creamy texture is achieved by adding a slice of dried out bread (torn into pieces) into the soup and then ultimately pureeing everything together in the blender. The flavors blend beautifully and the bread helps to give it a thickness that otherwise would need heavy doses of cream to achieve. I love how healthy that makes this soup!
The original recipe calls for chicken broth, but as a general rule of thumb, I use vegetable broth for any soup or dish that doesn’t include meat to begin with. This has become a habit since my sister became a vegetarian; I like to make sure that if something doesn’t have meat in it then mere broth won’t keep her from eating it. (The one exception to this rule is French Onion Soup!)
Have you ever eaten something at a function that you just can’t stop thinking about?!

Creamy Potato & Leek Soup
Ingredients
- 4 medium leeks, white and light-green parts halved lengthwise, washed, and sliced thin (about 4 cups), dark green parts halved, washed, and cut into 2-inch pieces
- 2 cups (470 ml) vegetable broth
- 2 cups (500 ml) water
- 4 tablespoons unsalted butter
- 1 cup (160 g) chopped onion
- 1 teaspoon salt
- 1 small russet potato, about 6 ounces, peeled, halved lengthwise, and cut into 1/4-inch slices
- 1 bay leaf
- 1 4-inch sprig fresh thyme or tarragon
- 1 large slice white sandwich bread, lightly toasted and torn into 1/2-inch pieces
- Ground black pepper
Instructions
- Bring dark-green leek pieces, broth, and water to boil in large saucepan over high heat. Reduce heat to low, cover, and simmer 20 minutes. Strain broth through fine-mesh strainer into medium bowl, pressing on solids to extract as much liquid as possible; set aside. Discard solids in strainer and rinse out saucepan.
- Melt butter in now-empty saucepan over medium-low heat. When butter foams, stir in sliced leeks, onion, and salt. Reduce heat to low and cook, stirring frequently, until vegetables are softened, about 10 minutes.
- Increase heat to high, stir in reserved broth, potato, bay leaf, and herb sprig and bring to boil. Reduce heat to low and simmer until potatoes are tender, about 10 minutes. Add toasted bread and simmer until bread is completely saturated and starts to break down, about 5 minutes.
- Remove and discard bay leaf and herb sprig. Transfer half of soup to blender and process until smooth and creamy, 2 to 3 minutes. Transfer to large bowl and repeat with remaining soup. Return soup to saucepan and bring to simmer over medium-low heat; season with salt and pepper to taste. Garnish and serve.

This soup was DELICIOUS!!! I used a large potato and omitted the bread. I also used the chicken broth. It was perfect! Thank you for such a great recipe!
Awww I just prepared the soup! It’s delicious :) The only thing I changed was the bread for milk! Thanks for the recipe!
Wowswers….just made it today. My 5 year old and dad in law both gobbled it up. Very very tasty
I love you and your recipes
This was delicious! I had some leftover mashed potatoes & used a scoop of that in lieu of the bread & it worked out great. I’m sad this only makes 4 servings! I guess I’ll have to make it again soon : )
Great recipe! Easy and delicious. I had some leftover pieces of grilled pork loin that I chopped in small chunks and added to the finished soup. It made it a little more hearty and filling.
I’ve made this twice now, and will make it a third time for Christmas. Since I never have white bread around, I substituted with 1/2 cup of Panko bread crumbs. It worked perfectly!
Do you know how to scale up this recipe ? Is it just a matter of times-ing everything by 7? I’m cooking for about 25 for a homeless shelter and this could be first course.
I’ve never scaled it that large, but yes, I would just increase everything seven-fold if that’s how much you need to make. Definitely let me know how it goes!
It tastes lovely – just right for a cold night in London.
Tried your recipe and the soup turned out great! It was very tasty and filling. Highly recommend and would make again.
I made this tonight. I didn’t have white bread so I used the Panko breadcrumbs. I used about 1/2 cup. It was perfect on the first rain of the season. Thanks for the wonderful recipe.
I have to say, I doubted this recipe. Only one, small potato?!? But, we forged ahead and am so glad we did. It’s really delicious! We used whole wheat bread and it turned out just fine. My Mom couldn’t get over that it didn’t have any cream in it. I ended up baking an additional potato separately and adding some chunks from that after the soup was blended just to stretch it a bit (and I like chunks of potato in soup) and that worked very well. But it certainly doen’t need it, very potato-y on it’s own. Thanks for such a great recipe!
I’ve tried this recipe twice now and my boyfriend and I just think it’s DIVINE. Do you think you could substitute bread into any soup recipe for heavy cream? We live in Turkey and it doesn’t seem to be available but I enjoy making soup.
FYI, I posted about your recipe on my blog: http://turkishlydelightful.blogspot.com/2011/11/adventures-in-cooking-potato-and-leek.html
Hi Melinda, It’s a good question, I don’t see why not!
I made this last week. A bit labor intensive, but it came out pretty good. I do feel like it needs a little bit more flavor but I’m not sure what exactly!
