What is Potato Leek Soup?

What to Serve With this Soup

What is in Potato Leek Soup?

  • Leeks – leeks have a similar flavor to onions and green onions. They look like thicker green onions. They have a unique flavor compared to regular onions and they pair perfect with potatoes and sour cream in this soup.
  • Potatoes – we recommend Yukon gold potatoes for this recipe. They have a creamy texture that is perfect when pureed. You can also use russet potatoes or any potatoes you have on hand.
  • Broth – vegetable or chicken broth can be used. To keep the recipe vegetarian you can use vegetable broth. For added nutrients chicken bone broth can be used instead!
  • Sour Cream – potatoes + sour cream + leeks = match made in heaven! Sour cream pairs so perfectly with potatoes. It adds a creamy texture and tangy flavor to the soup. For a healthier option you can swap for plain yogurt.
  • Garlic – everything is better with garlic so of course this soup is packed with minced garlic!
  • Chives – used to garnish the soup, it compliments the leek flavor.
  • Thyme – a classic herb used in French cooking.
  • Bay Leaf
  • Oil
  • Salt and Pepper

1 Slice the leeks into ¼-inch thick slices. Soak in a bowl of water and then rinse well under running water to remove all dirt and sediment. Drain well and set aside.

2 In a large soup pot or Dutch oven, over medium heat add the olive oil. Add in the rinsed leeks, garlic, thyme. Sauté until tender, golden, and fragrant for about 8-10 minutes.

3 Add the Yukon gold potatoes, vegetable broth, bay leaves, salt, and black pepper.

4 Bring to a boil, cover and reduce the heat to low and simmer, covered, for 10-15 minutes, until potatoes are fork tender.

5 Remove the bay leaves from the soup.

6 Using an immersion blender, blend the soup until smooth.

7 Slowly stir in the sour cream or yogurt and bring to a simmer. Taste and adjust seasoning with salt and pepper.

8 If the soup is too thin, simmer until thickened. If it’s too thick, add water or stock to thin it out.

9 Garnish with an additional dollop of sour cream, sliced fresh chives or green onions and enjoy!

Tips for the Best Potato Leek Soup

  • Potatoes – for best results we recommend Yukon gold potatoes. They have a lower starch level compared to other potatoes. This means they have a more waxy texture which makes them perfect for soups that are pureed. The result is a rich and creamy soup. If you do not have Yukon gold potatoes, the next potato we recommend would be russet potatoes.
  • Leeks – it is very important to thoroughly wash and clean the leeks. Due to the way leeks grow they get dirt stuck between the layers. Once you have thinly sliced the leeks for the soup simply soak them in a bowl of water and stir them to make sure each piece of leek is fully cleaned. Some grocery store sell pre-washed sliced leeks. If you can find those you can use them for the recipe too!

Can I freeze this Soup?

This soup is freezer friendly but the texture of the soup will change. Since the soup has sour cream/yogurt in the broth the soup will not be as thick if it’s frozen and then reheated. To solve this, you can reheat the soup stove top and allow it to simmer for 2-3 minutes, this will remove the excess liquid and thicken the soup again.
