Ingredients in potato leek soup
Potato leek soup is a classic soup of European origin made with potatoes, leeks, broth, seasonings, and heavy cream. There are traditional versions of this dish in Welsh, Romanian and French cooking. Another variation is vichyssoise or potage Parmentier, made with similar ingredients but served cold. This spin on the recipe is made the classic American way: we’ve added a few other ingredients to flavor the body of the soup like garlic and leeks. While we love embracing healthy recipes on this website, the heavy cream really does pull this soup together! It’s a small quantity per serving and the milkfat helps to add a luxurious richness. Here’s what you’ll need:
Salted butter Leeks Celery Garlic Russet potatoes Broth (vegetable or chicken) Fresh thyme Bay leaf Salt Heavy cream
How to cut and clean leeks
Leeks are a vegetable that’s part of the onion (allium) family. They look like a large green onion, with a white stalk that fades to light green with darker green leaves. Leeks are typically much dirtier than green onions: sand and dirt can get stuck between the layers of the white portion. For that reason, it’s very important to cut and clean leeks before working with them. Here’s how to do it:
How to use leek greens
What’s the best way to use use leek greens? Some people say you can use them for vegetable broth, but others say that leek greens have the potential to add bitterness to recipes. Our recommendation?

Tips for this potato leek soup recipe
Once you’ve cleaned and chopped the leeks for this recipe, the rest of the soup is a breeze! Here are a few more notes on making this cozy recipe:
Use thyme sprigs and bay leaf, or a bouquet garni. Whole herbs add flavor to the soup, which you’ll remove after simmering. If you like, you can use a bouquet garni, which ties the herbs in cheesecloth and kitchen string. This makes them easier to remove from the pot after simmering. Use a standard blender, not an immersion blender. Typically we like the slick method of placing a stick blender right into a pot of soup and blending away. But with this soup, it doesn’t get it nearly creamy enough. We recommend carefully transferring to a blender (careful! the soup is hot). Don’t lighten up on the cream. Stirring in heavy cream at the end gives just the right rich body to this soup. Don’t be tempted to use milk: it works, but it’s not nearly as satisfying.
