Step-by-Step Instructions

Here’s how to make Potato Leek Soup:

Sauté the Leeks:

1. Melt Butter/Heat Oil: In a large pot or Dutch oven, melt the butter or heat the olive oil over medium heat.
2. Add Leeks: Add the sliced leeks to the pot and sauté for 8-10 minutes, stirring occasionally, until softened and translucent but not browned. It’s important to cook the leeks gently to develop their sweetness.
3. Add Garlic (Optional): If using garlic, add it to the pot during the last minute of sautéing, being careful not to burn it.

Simmer the Soup:

1. Add Broth and Potatoes: Pour in the vegetable broth or chicken broth, add the cubed potatoes, salt, and pepper.
2. Bring to a Boil, Then Simmer: Bring the soup to a boil, then reduce the heat to low, cover, and simmer for 20-25 minutes, or until the potatoes are very tender and easily pierced with a fork.

Blend the Soup:

1. Blend: Carefully transfer the soup to a blender (in batches if necessary) or use an immersion blender to blend until smooth and creamy. Be cautious when blending hot liquids; vent the blender lid to prevent pressure buildup.
2. Return to Pot: If using a regular blender, return the blended soup to the pot.

Finish and Serve:

1. Add Cream (Optional): If using heavy cream or crème fraîche, stir it into the soup. Heat through gently, being careful not to boil.
2. Adjust Seasoning: Taste and adjust seasoning with salt and pepper as needed.
3. Serve: Ladle the soup into bowls and garnish with fresh chives or parsley, if desired. Serve hot.

Additional Tips for Potato Leek Soup

Here are some tips to ensure your Potato Leek Soup is perfect every time:

• Clean Leeks Thoroughly: Leeks tend to trap dirt between their layers, so be sure to clean them thoroughly. Slice them lengthwise, then rinse them well under cold running water, separating the layers to remove any dirt.
• Don’t Brown the Leeks: Cook the leeks gently over medium heat until softened and translucent but not browned. Browning the leeks can make the soup taste bitter.
• Use the Right Potatoes: Yukon Gold potatoes are the best choice for this soup, as they have a naturally buttery flavor and creamy texture. Avoid using Russet potatoes, which can be too starchy.
• Simmer, Don’t Boil: Simmer the soup gently to allow the flavors to meld together. Boiling the soup can make the potatoes become mushy.
• Adjust the Consistency: If the soup is too thick, add more broth to thin it out. If it’s too thin, simmer it uncovered for a few minutes to allow it to reduce.
