Frequently Asked Questions (FAQs)

What kind of potatoes should you use for potato leek soup?

We recommend using either Yukon gold or Russet potatoes for the soup, as it will result in a creamier texture. While red-skinned waxy potatoes aren’t the best for a soup as they tend to hold their shape, you want a potato that will purée well in this soup.

How can you make potato leek soup thick and creamy?

Just blend the cooked soup in an immersion blender until thick and smooth. If you are using Yukon gold potatoes, they will produce a creamy texture. If you want chunky soup, only purée half.

Why is my potato leek soup gluey?

If the potatoes are blended too thoroughly, they release gelatinized starch into the broth, slimming the soup.

Which part of the leek is used in soup?

Many recipes call for just the white part of the leeks to give the soup a paler color, but using the green part will add flavor and provide brilliant light green to the soup.
