Potato Leek Soup

For years, I’ve been a huge fan of Potato Leek Soup. It’s one of those soups that I’ll order at a restaurant just about any time I see it on the menu.

Lucky for me, my husband Jack makes a delicious homemade Potato Leek Soup. It’s better than most restaurant versions I’ve tasted – and we’re happy to share the recipe with all of you today!


Potato Leek Soup

What are leeks?

Leeks are a vegetable that resembles a large scallion or green onion.  Officially part of the same family as onions – leeks have a similar, but distinctive and milder flavor that is very delicious.

The edible part of the leek is the lower, whiter and lighter green portions of the stalk closest to the roots. (The darker green ends are usually too tough to eat.)

Leeks are notoriously sandy, so make sure you rinse the stalks very well – before adding them to this soup or any other recipe that calls for leeks.

How do you make Potato Leek Soup?

Potato Leek Soup is very easy to make. We started off by sautéing chopped leeks, onions, celery and garlic in butter until soft and translucent.

Next, we add peeled and diced Russet and yellow potatoes and chicken (or vegetable) stock to the pot along with some fresh thyme and a couple of bay leaves.  Simmer until the potatoes are tender – then remove the herbs.

Puree the potato leek mixture until smooth and stir in cream. Seasoning with salt and pepper as needed, then serve with chopped chives on top.

Is Potato Leek Soup served hot or cold?

The choice is really yours. Leek season officially runs October through May, so seasonally, that lends itself to serving this soup warm. But I’ve often seen Potato Leek Soup on the menu in the summer – and it’s delicious served chilled as well.

Either way – serving this soup with the fresh, chopped chives on top is really the perfect finishing touch. The fresh bite of the chives is a wonderful contrast to the rich and creamy soup. (We served this Potato Leek Soup at a recent brunch for Jack’s cousin Susan and her boyfriend Craig (Hi! 😊) and everyone agreed – don’t forget the chives on top!

    I was looking for a soup to use a big bunch of russet potatoes – but almost all recipes I see use yukon gold. At least this one has SOME russets, but what is the obsession with yukon gold? I like them cooked whole, roasted, put into salads or browned in oil but they don’t seem to be the kind of potato I would think of for soup (or mashed potatoes, for that matter). Is there a reason? Luckily I still have old Joy of Cooking cookbooks so checked there as well – assuming they use traditional French recipes, not a whisper about yukon gold. they have russsets in the “classic French version” so I am going to believe Joy of Cooking knows what it’s talking about, and also makes sense to me too texture wise – plus I can save my cute yiukon gold for other things.
