What makes Once Upon a Chef potato leek soup so creamy?

The combination of starchy Yukon Gold potatoes and slow-cooked leeks creates a naturally thick base. Blending the soup and finishing with heavy cream gives it that signature silky texture that the recipe is known for.

Can I make this potato leek soup dairy-free?

Yes. Swap the butter for olive oil and replace the heavy cream with full-fat coconut milk or a dairy-free creamer. The soup will still be rich and satisfying — the coconut flavor is subtle enough not to compete.

Can I freeze potato leek soup?

You can, though cream-based soups may separate slightly after thawing. For best results, freeze the soup before adding cream, then stir in fresh cream when you reheat it. The texture will be much smoother.

What kind of potatoes work best for this soup?

Yukon Gold potatoes are the best choice because they blend to a buttery, creamy consistency. Russets work in a pinch, but they can make the soup slightly gluey if you over-blend them, so keep an eye on the texture.

How long does potato leek soup keep in the refrigerator?

Stored in an airtight container, this soup keeps well in the refrigerator for up to 4 days. Reheat gently on the stovetop over low heat, adding a splash of broth if the soup has thickened.
