Ingredients List for Potato Leek Soup

To make this delicious soup, you'll need a handful of simple and fresh ingredients. Here’s what you'll need:

• 2 tablespoons extra-virgin olive oil: This provides the base for sautéing the leeks and garlic, giving them a rich and smooth flavor.
• 3 large leeks: Be sure to use only the white and light green parts, as the darker green tops can be tough and fibrous. Thoroughly clean the leeks to remove dirt and grit.
• 2 garlic cloves, minced: Fresh garlic enhances the savory profile of the soup.
• 4 cups vegetable broth: The broth forms the liquid base, adding depth and richness to the flavor. If you prefer a thinner consistency, feel free to add more.
• 2 pounds Yukon Gold potatoes: Peeled and diced into ½-inch pieces. These potatoes are buttery and slightly sweet, making them perfect for this soup.
• 1 teaspoon kosher salt: Helps to balance the flavors and enhance the taste of the soup.
• 1 bay leaf: Adds a subtle, earthy aroma to the broth.
• 2 sprigs of fresh thyme: Thyme offers a mild, herbal fragrance that complements the leeks and potatoes.
• Freshly chopped chives and black pepper for garnish: These finishing touches provide a pop of color and a hint of spice.

Substitutions and Variations

If you don’t have all of the ingredients on hand or prefer to make some adjustments, here are some easy substitutions and variations:

1. Leeks: If you can’t find leeks, substitute with onions or shallots. While these won’t provide the exact same flavor, they’ll still give a pleasant oniony base to the soup.
2. Yukon Gold Potatoes: Russet or red potatoes can also be used, but Yukon Golds are preferred for their creamy texture.
3. Vegetable Broth: For a richer flavor, you can use chicken broth instead. If you want to make it vegan, stick to vegetable broth.
4. Olive Oil: If you prefer a more buttery taste, you can substitute olive oil with butter.
5. Herbs: Feel free to experiment with other herbs such as rosemary, parsley, or dill.
6. Creamy Texture: For a creamier soup, you can add a splash of heavy cream or coconut milk right before serving. You can also puree more of the soup if you prefer a smoother texture.

Step-by-Step Cooking Instructions

Ready to get started? Follow these simple steps to make a creamy, flavorful Potato Leek Soup from scratch.

Step 1: Prepare the Leeks

Begin by cleaning the leeks thoroughly. Slice off the dark green tops and root ends, and use only the white and light green parts. Slice the leeks lengthwise, then cut into thin half-moons. Submerge the slices in a bowl of cold water and swish around to remove any hidden dirt or grit. Drain well.

Step 2: Sauté the Leeks and Garlic

In a large pot, heat 2 tablespoons of extra-virgin olive oil over medium heat. Add the leeks and cook for about 5-7 minutes, stirring occasionally, until they become soft and fragrant. Add the minced garlic and cook for another minute, making sure the garlic doesn’t burn.

Step 3: Add the Potatoes and Broth

Next, add the diced Yukon Gold potatoes to the pot. Pour in the vegetable broth, ensuring the potatoes are fully submerged. Add the bay leaf and thyme sprigs for added flavor. Bring the mixture to a boil, then reduce the heat to low and let it simmer for about 20-25 minutes, or until the potatoes are tender.

Step 4: Remove Bay Leaf and Thyme

Once the potatoes are cooked through, remove the bay leaf and thyme sprigs. These are for flavoring and should not be left in the soup.

Step 5: Blend the Soup

For a creamy texture, use an immersion blender directly in the pot to puree the soup until smooth. If you don’t have an immersion blender, carefully transfer the soup in batches to a regular blender and blend until smooth. Be sure to let the soup cool slightly before blending to avoid any accidents.

Step 6: Season and Garnish

Taste the soup and season with kosher salt as needed. For added richness, you can also stir in a small amount of cream or butter. Serve the soup hot, garnished with freshly chopped chives and a sprinkle of black pepper.

Common Mistakes to Avoid

1. Not Cleaning the Leeks Thoroughly: Leeks often have dirt hidden between their layers. Make sure to soak and rinse them well to avoid grit in your soup.
2. Overcooking the Potatoes: While you want the potatoes to be tender, overcooking them can lead to a mushy, undesirable texture.
3. Blending Too Early: Let the soup cool slightly before blending to avoid hot splashes and burns.
