Potato Leek Soup: A Creamy & Delicious Recipe

Potato Leek Soup

Ingredients:

  • 2 tablespoons olive oil
  • 1 large leek, white and light green parts only, thoroughly cleaned and thinly sliced
  • 2 cloves garlic, minced
  • 1 pound Yukon Gold potatoes, peeled and cubed
  • 6 cups vegetable broth (or chicken broth for a richer flavor)
  • 1 teaspoon dried thyme
  • 1/2 teaspoon salt, or to taste
  • 1/4 teaspoon black pepper, or to taste
  • 1/2 cup heavy cream (optional, for extra creaminess)
  • Fresh chives, chopped (for garnish)
  • Crispy croutons (for garnish, optional)
  • A drizzle of olive oil (for garnish, optional)

Preparing the Leeks and Potatoes:

Okay, let’s get started! The key to a great potato leek soup is really taking the time to properly prepare the leeks. They can be gritty, so cleaning them well is super important.

  1. Cleaning the Leeks: Leeks are notorious for hiding dirt between their layers. To clean them properly, first, slice off the root end and the dark green parts (save the dark green parts for making vegetable stock if you like!). Then, slice the white and light green parts lengthwise down the middle, but not all the way through the root end. Fan out the layers and rinse them thoroughly under cold running water, making sure to get rid of any dirt or sand. Once they’re clean, thinly slice them.
  2. Preparing the Potatoes: Peel the potatoes and cut them into roughly 1-inch cubes. Uniform size helps them cook evenly. I prefer Yukon Gold potatoes for their creamy texture, but Russet potatoes will also work, although the soup might be a bit starchier.

Sautéing the Aromatics:

Now for the flavor building! This is where the magic happens, and we coax out all those delicious savory notes.

  1. Sautéing the Leeks: In a large pot or Dutch oven, heat the olive oil over medium heat. Add the sliced leeks and cook, stirring occasionally, until they are softened and translucent, about 8-10 minutes. Be careful not to brown them too much, as you want them to be sweet and mild. If they start to brown too quickly, reduce the heat slightly.
  2. Adding the Garlic: Add the minced garlic to the pot and cook for another minute, until fragrant. Be careful not to burn the garlic, as it can become bitter. Stir constantly to prevent burning.

Simmering the Soup:

Time to bring it all together and let the flavors meld into a comforting, creamy soup.

  1. Adding the Potatoes and Broth: Add the cubed potatoes, vegetable broth (or chicken broth), dried thyme, salt, and pepper to the pot. Stir to combine.
  2. Simmering: Bring the soup to a boil, then reduce the heat to low, cover, and simmer for 15-20 minutes, or until the potatoes are very tender and easily pierced with a fork.

Blending the Soup:

This is where we transform the chunky mixture into a velvety smooth soup. You have a couple of options here, depending on your preference and equipment.

  1. Using an Immersion Blender: If you have an immersion blender, carefully insert it into the pot and blend the soup until it is smooth. Be careful not to splash the hot soup.
  2. Using a Regular Blender: If you’re using a regular blender, you’ll need to work in batches. Carefully transfer the hot soup to the blender (do not fill it more than halfway!), secure the lid tightly, and vent the lid by removing the center piece. Cover the lid with a towel to prevent splattering. Blend until smooth. Repeat with the remaining soup.

Finishing Touches:

Almost there! Now for the final touches that elevate this soup to the next level.

  1. Adding Cream (Optional): If you’re using heavy cream, stir it into the blended soup. Heat gently over low heat until warmed through. Do not boil. This adds richness and a luxurious texture.
  2. Adjusting Seasoning: Taste the soup and adjust the seasoning as needed. You may want to add more salt, pepper, or thyme to taste.

Serving:

The best part! Time to enjoy your homemade potato leek soup.

  1. Garnishing: Ladle the soup into bowls and garnish with fresh chopped chives, crispy croutons, and a drizzle of olive oil (if desired).
  2. Serving Suggestions: Serve hot with a side of crusty bread for dipping. This soup is also delicious with a dollop of sour cream or crème fraîche.

Tips and Variations:

Here are a few extra tips and ideas to customize your potato leek soup:

  • For a Vegan Version: Omit the heavy cream or substitute with coconut cream or cashew cream for a dairy-free alternative. Ensure your vegetable broth is vegan-friendly.
  • Add Bacon: Cook some bacon until crispy, crumble it, and add it to the soup as a garnish. The smoky flavor of the bacon complements the sweetness of the leeks and the creaminess of the potatoes perfectly.
  • Add Cheese: Stir in some shredded Gruyere or Parmesan cheese after blending the soup for a cheesy twist.
  • Make it Spicy: Add a pinch of red pepper flakes or a dash of hot sauce to the soup for a little kick.
  • Use Different Herbs: Experiment with different herbs, such as rosemary or sage, to add a unique flavor profile.
  • Roast the Vegetables: For a deeper, more complex flavor, roast the leeks and potatoes before adding them to the soup. Toss them with olive oil, salt, and pepper, and roast at 400°F (200°C) for 20-25 minutes, or until tender and slightly browned.
  • Make it Ahead: Potato leek soup can be made ahead of time and stored in the refrigerator for up to 3 days. Reheat gently before serving. The flavors actually meld together even more over time!
  • Freezing: This soup freezes well. Let it cool completely before transferring it to freezer-safe containers. Freeze for up to 2 months. Thaw overnight in the refrigerator before reheating. Note that the texture may change slightly after freezing and thawing, especially if you added cream.
Troubleshooting:

Sometimes things don’t go exactly as planned. Here are a few common issues and how to fix them:

  • Soup is Too Thick: If the soup is too thick, add more broth until it reaches your desired consistency.
  • Soup is Too Thin: If the soup is too thin, simmer it uncovered for a few minutes to allow some of the liquid to evaporate. You can also add a slurry of cornstarch and water (1 tablespoon cornstarch mixed with 2 tablespoons cold water) to thicken it.
  • Soup is Bland: If the soup tastes bland, add more salt, pepper, or herbs. A squeeze of lemon juice can also brighten up the flavor.
  • Soup is Gritty: If the soup is gritty, it means the leeks weren’t cleaned properly. Unfortunately, there’s not much you can do to fix this after the soup is made. Be sure to clean the leeks thoroughly next time!
