Key Ingredients
Here’s what you need to make this delicious and classic leek and potato soup recipe:
Leeks: Part of the onion family, this vegetable has a flavor like mild garlic, and is perfect for soup-making. Potatoes: Choose a lower starch potato such as Yukon Gold in the US. If you’re in the UK, look for Maris Piper or King Edward Potatoes. In Australia, your best choice will be Sebago potatoes. Garlic, Thyme, Pepper, Salt: Simple seasonings are all you need. Heavy Cream: Use about a half cup of rich heavy cream to make your soup silky smooth and extra creamy. Stock: You can use either vegetable stock or chicken stock to make this recipe.

How To Make Potato Leek Soup
Recipe Tips
To Prep the Leeks: It’s important to wash the leeks very well, as their layers will hold on to dirt from the growing process. I like to thinly slice the white and light green parts only of the leek, then rinse the slices in cold water to remove any grit. You can toss the tough dark green tops of the leeks, or save them to add flavor to your next batch of vegetable stock. Potato Choice is Important: While you can technically use any kind of potato to make potato leek soup, I suggest that you choose an all-purpose potato such as Yukon Gold. Russet potatoes can be used, but they will make the soup thicker, so you may need to adjust the amount of liquid. Don’t Blend Too Much: Use a hand blender, and blend only enough to make the soup smooth. Overmixing will make this soup sticky and unpleasantly textured. To Make Dairy-Free Soup: Omit the heavy cream, or replace it with canned coconut milk or cream. Even without any milk, the soup will still be delicious and creamy from the potatoes. Garnishes: Crunchy homemade croutons (or try my air fryer croutons) are so tasty with this creamy soup! Fresh chives or parsley will add a beautiful bit of color too.
Storing Tips
Leftover potato leek soup can be stored in the refrigerator for up to 4 days. Reheat servings on the stovetop over low heat, stirring occasionally until it’s warmed through. To freeze this soup, allow it to cool first, then transfer it to freezer bags or containers. Soup with potatoes is best if you don’t keep it frozen for more than a month. Thaw overnight in the fridge and reheat the next day.
What To Serve With Potato Leek Soup
As you see here, I love to enjoy this rich and silky smooth soup with crunchy homemade croutons. It’s also delicious with slices of rustic bread or a side of homemade breadsticks. This soup pairs well with sandwiches too. Just like at your favorite diner restaurant, soup and sandwiches make a wonderful dinner or lunch meal. Try my tarragon chicken salad, chicken pesto sandwich, or a classic patty melt.
Can I Make Leek Soup Without Potatoes?
For a lower-carb version of potato leek soup, try my recipe for cauliflower leek soup instead! It’s blended the same way so that it’s nice and creamy but without any potatoes.
Can I Make This Soup Without a Blender?
If you don’t have an immersion blender, you can mash the potatoes in the soup with a potato masher instead. The soup will be less smooth, but still delicious.
How Should I Clean Leeks?
Start by trimming off the roots and the dark green tops of the leeks. Then use a sharp knife to slice the leeks into thin pieces. Rinse the sliced leeks in cool running water to remove any grit. This creamy and comforting Potato Leek Soup is a total mood booster for a dreary day.
