With its creamy texture, subtle sweetness, and savory flavors, this soup is a masterclass in comfort food.
The Secret to a Rich and Creamy Texture
The key to a truly exceptional potato leek soup lies in the cooking technique and the quality of the ingredients. To achieve a rich and creamy texture, you'll want to use a combination of high-starch potatoes and a generous amount of leeks. But what sets the best potato leek soup apart from the rest is the use of a roux-based thickening agent.
Why Leeks Are the Unsung Heroes of This Soup
Leeks are often overlooked in favor of more showy ingredients, but they bring a depth of flavor and a delicate sweetness that's essential to this soup. To get the most out of your leeks, be sure to use a combination of the white and light green parts, and chop them finely before sautéing them in butter until they're soft and fragrant.

While some recipes may call for a splash of heavy cream or half-and-half to add richness and creaminess, we prefer to use a combination of chicken or vegetable broth and a roux-based thickening agent to achieve the perfect consistency.
The Best Potatoes for the Job
When it comes to selecting the best potatoes for potato leek soup, you'll want to choose high-starch potatoes that will yield a creamy texture when cooked. Some of the best options include Russet, Idaho, or Yukon Gold potatoes. These potatoes have a higher starch content than waxy potatoes like red or new potatoes, which will result in a thicker, creamier soup.
A Recipe for Success: The Best Potato Leek Soup
Here's a basic recipe for potato leek soup that you can modify to suit your tastes:
- 4-6 medium-sized potatoes, peeled and chopped into 1-inch cubes
- 2 large leeks, chopped and sautéed in butter until soft and fragrant
- 2 tablespoons all-purpose flour
- 2 cups chicken or vegetable broth
- 1/2 cup milk or heavy cream (optional)
- Salt and pepper to taste
- Grated cheddar cheese (optional)
Start by sautéing the chopped leeks in butter until they're soft and fragrant, then set them aside. In a large pot, combine the chopped potatoes, broth, and sautéed leeks. Bring the mixture to a boil, then reduce the heat and simmer until the potatoes are tender.
Using an immersion blender or a regular blender, puree the soup until smooth. Return the soup to the pot and stir in the flour to thicken. If desired, add a splash of milk or heavy cream to give the soup a creamy texture. Season with salt and pepper to taste, then serve hot, topped with grated cheddar cheese if desired.
The Benefits of a Hearty Soup Like Potato Leek
Not only is potato leek soup a delicious and comforting meal option, but it also offers a range of health benefits. The high starch content of potatoes makes them a good source of complex carbohydrates, while the leeks provide a boost of vitamin K and fiber. The soup is also relatively low in calories, making it a great option for those looking for a satisfying meal without the guilt.
