How to Make Potato Leek Soup

Creating this wonderful Potato Leek Soup is totally achievable. Follow these simple steps. You’ll have a delicious soup ready soon. It’s easier than you might think.
Step 1
Melt the butter in a big pot. Use medium heat. Add your cleaned leeks. Add the chopped onion too. Stir them gently. Cook until they start to get soft. This takes about 8 to 10 minutes. You don’t want them to brown at all. Just a nice, gentle softening.
Step 2
Now, add the minced garlic. Stir it around. Cook for just one more minute. You’ll smell how fragrant it gets. This step builds amazing flavor for your soup.
Step 3
Pour in the broth. Add the diced potatoes. Sprinkle in your salt and pepper. Give everything a good stir. Bring this mixture up to a boil. Then, turn the heat down low. Put a lid on the pot. Let it simmer gently. Cook for about 20 to 25 minutes. The potatoes should be really tender when they’re done. This is key for a smooth, creamy soup.
Step 4
Take the pot off the heat. Now, it’s time to make it smooth. Use an immersion blender right in the pot. Blend until it’s perfectly smooth. Or, if you don’t have one, be careful. Transfer the soup in batches. Use a regular blender. Blend until it’s smooth. Always vent the lid on a regular blender. This lets hot steam escape. It prevents messy splashes.
Step 5
Stir in the heavy cream or half-and-half. Do this if you’re using it. Warm the soup gently. Don’t let it boil again. Taste the soup. Add more salt or pepper if you need. Make sure the flavors sing!
Step 6
Serve this lovely soup hot. Garnish with fresh chives. Or use chopped parsley. It adds a nice touch. Enjoy your homemade Potato Leek Soup!
How to Store Potato Leek Soup
Storing this delightful Potato Leek Soup is simple. Keep leftovers in an airtight container in your refrigerator. It stays fresh for about 3 to 4 days. For longer storage, this soup freezes beautifully! Let it cool completely. Then, portion it into freezer-safe containers or bags. Frozen soup is best enjoyed within 2-3 months.

Tips for Success

What are good ingredient swaps for this leek soup recipe?
You can easily swap ingredients in this leek soup. For a dairy-free version, use coconut milk or a plant-based creamer instead of heavy cream.

Description
A classic and comforting Potato Leek Soup that is simple to make and incredibly satisfying.
Ingredients
- 2 tablespoons unsalted butter
- 3 medium leeks (white and light green parts only), cleaned and thinly sliced
- 1 medium yellow onion, chopped
- 2 cloves garlic, minced
- 4 cups chicken or vegetable broth
- 3 cups peeled and diced potatoes (about 1.5 lbs, Yukon Gold or Russet recommended)
- 1 teaspoon salt (or to taste)
- 1/2 teaspoon black pepper (or to taste)
- 1/2 cup heavy cream or half-and-half (optional)
- Fresh chives or parsley, chopped (for garnish)
Instructions
- In a large pot or Dutch oven, melt butter over medium heat. Add sliced leeks and chopped onion. Cook, stirring occasionally, until softened, about 8-10 minutes. Do not brown.
- Add minced garlic and cook for another minute until fragrant.
- Stir in the chicken or vegetable broth, diced potatoes, salt, and pepper. Bring the mixture to a boil, then reduce heat to low, cover, and simmer for 20-25 minutes, or until potatoes are very tender.
- Remove the pot from heat. Using an immersion blender, blend the soup directly in the pot until smooth. Alternatively, carefully transfer the soup in batches to a standard blender and blend until smooth. (If using a standard blender, be sure to vent the lid to allow steam to escape and avoid hot splashes).
- Stir in the heavy cream or half-and-half (if using) and heat gently for a few minutes, do not boil. Taste and adjust seasonings as needed.
- Serve hot, garnished with fresh chives or parsley.
Notes
- For a richer soup, use heavy cream. For a lighter option, use half-and-half or omit entirely.
- Ensure leeks are thoroughly cleaned to remove any grit.
- Yukon Gold potatoes will yield a creamier texture, while Russet potatoes will result in a starchier, thicker soup.
