What Is Potato Leek Soup?
Potato Leek Soup is a classic French-inspired dish that has become a staple in many kitchens worldwide. Traditionally made with leeks, potatoes, broth, and aromatic herbs, this soup is often puréed for a smooth and creamy texture. It's a versatile dish, adaptable to various dietary preferences, and can be served hot or cold (vichyssoise). This soup is an ideal option for family dinners, casual get-togethers, or even meal prepping.
Now that you know what it is, let’s dive into the ingredients you’ll need to make this rich and flavorful soup.
Ingredients List for Potato Leek Soup
To make a delicious Potato Leek Soup, you’ll need a handful of simple, wholesome ingredients that come together to create an incredibly flavorful and creamy dish. Here’s what you’ll need:
- 2 tablespoons extra-virgin olive oil – This is used to sauté the leeks and garlic, adding a rich and slightly fruity flavor base to the soup.
- 3 large leeks – The star of the show! Leeks provide a mild, onion-like flavor but with a slightly sweeter and more delicate taste. Be sure to clean them well as dirt often gets trapped between their layers.
- 2 garlic cloves, minced – Garlic brings a savory undertone and enhances the overall flavor of the soup.
- 4 cups vegetable broth – This forms the liquid base of the soup. Use a good-quality vegetable broth for the best flavor.
- 2 pounds Yukon Gold potatoes, peeled and diced into ½-inch pieces – Yukon Gold potatoes are perfect for this recipe because of their naturally creamy texture. They’ll help thicken the soup without needing any added cream.
- 1 teaspoon kosher salt – Balances the flavors and enhances the sweetness of the leeks and potatoes.
- 1 bay leaf – A classic addition to soups, this adds depth and complexity to the broth.
- 2 sprigs of fresh thyme – Thyme complements the flavor of the leeks and potatoes, adding an earthy and aromatic quality.
- Freshly chopped chives and black pepper for garnish – These add a bit of color and a finishing touch of flavor to the soup.
Substitutions and Variations
Potato Leek Soup is very adaptable, and you can easily tweak the recipe to suit your dietary preferences or available ingredients. Here are some common substitutions and variations:
- Dairy-free: While this recipe doesn’t include dairy by default, some recipes call for cream. You can skip the cream, or if you prefer a creamier texture, use coconut milk or cashew cream as a dairy-free alternative.
- Meat-based broth: If you're not strictly vegetarian, chicken broth can be substituted for vegetable broth for a richer, heartier flavor.
- Add cream or butter: For an even richer texture, stir in a splash of heavy cream or a pat of butter just before serving.
- Spice it up: Want to add some heat? Consider adding a pinch of red pepper flakes or a dash of cayenne pepper to the soup.
- Other herbs: If you don’t have thyme on hand, rosemary, parsley, or even tarragon can work as substitutes, giving the soup a slightly different but equally delicious flavor profile.
Step-by-Step Cooking Instructions
Now that you have all your ingredients ready, let's go through the step-by-step process to cook this delicious soup.

Step 1: Prepare the Leeks
Cut off the dark green parts of the leeks and discard them, leaving the white and light green parts. Slice the leeks lengthwise, then chop them into thin half-moons. Rinse them thoroughly in a bowl of water to remove any dirt or sand.
Step 2: Sauté the Leeks and Garlic
Heat the olive oil in a large pot over medium heat. Add the chopped leeks and garlic, and sauté for about 5-7 minutes, stirring frequently until the leeks become soft and translucent but not browned. The gentle cooking will bring out the leeks' sweet flavor.
Step 3: Add Potatoes, Broth, and Herbs
Once the leeks are softened, add the diced Yukon Gold potatoes, vegetable broth, bay leaf, thyme, and kosher salt. Stir well to combine. Bring the soup to a boil, then reduce the heat to low. Cover and let it simmer for about 20-25 minutes, or until the potatoes are tender when pierced with a fork.
Step 4: Purée the Soup
Once the potatoes are cooked through, remove the bay leaf and thyme sprigs from the pot. Use an immersion blender to purée the soup until smooth. If you don’t have an immersion blender, you can transfer the soup in batches to a regular blender, but be careful of the hot liquid.
Step 5: Adjust the Consistency
If the soup is too thick, add more vegetable broth until you reach your desired consistency. You can also adjust the seasoning by adding more salt or pepper if needed.
Step 6: Garnish and Serve
Ladle the soup into bowls and garnish with freshly chopped chives and a sprinkle of black pepper. Serve immediately with some crusty bread or a side salad for a complete meal.
Common Mistakes to Avoid
- Not cleaning the leeks thoroughly: Leeks tend to trap a lot of dirt between their layers, so make sure to wash them well. Skipping this step can lead to a gritty soup.
- Overcooking the leeks: Leeks can become bitter if overcooked, so make sure to sauté them until soft but not browned.
- Blending too much: While you want the soup to be creamy, blending it for too long can make it gluey. Blend just until smooth.
- Using the wrong type of potatoes: Avoid waxy potatoes like red potatoes, which won’t break down as easily. Yukon Gold potatoes work best for their creamy texture.
Serving and Presentation Tips
A well-made Potato Leek Soup deserves to be served in a way that highlights its creamy and velvety texture. Here are some tips for serving and presenting your soup:
How to Serve Potato Leek Soup
- As a starter: This soup is light yet filling, making it the perfect starter for a multi-course meal.

Presentation Ideas for Potato Leek Soup

Potato Leek Soup Recipe Tips
- Batch cooking: This soup freezes beautifully. Make a double batch and store leftovers in the freezer for easy weeknight meals.
- Season gradually: Always taste as you go, especially when adding salt. The broth can be salty, and you don't want to over-season the soup.
- Adding creaminess: If you prefer an ultra-creamy texture, stir in a bit of cream or non-dairy milk just before serving.
