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!

Ingredients  

  • 3 large leeks white only
  • 2 ribs celery ½-inch chopped
  • ½ cup butter
  • 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 thyme leaves
  • salt and black pepper to taste
  • 1 cup heavy whipping cream
  • chopped fresh chives or thyme for garnish

Instructions 

  • 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.

Notes

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. This soup is fantastic. I didn’t blend mine as I like the soft chunks of veg. I used white pepper like my Mam used to. It was so good. I will definitely make it again. It will be a regular soup for me.5 stars

  2. Pure comfort, purely delicious! A cinch to put together, this soup paired well with a grilled cheese sandwich (a favorite among our family) otherwise a simple baguette and butter would be perfect!5 stars
