Creamy Potato Leek Soup Recipe – Healthy Classic!

Potato leek soup is a classic French recipe that is a blend of fresh leeks, creamy potatoes, and flavorful herbs.

While traditionally it is laden with dairy-filled heavy cream…

It can easily be made vegetarian, vegan, Whole30, and dairy-free with a few easy-to-find ingredients!  (And of course it’s already gluten-free!)

When I first tried this recipe I thought I was supposed to use the dark green part of the fresh leeks.

Man was that a disaster!

The soup wasn’t completely inedible – but it definitely had an underlying bitterness that no amount of salt could hide.

Then I learned how to properly prepare leeks.  It was actually so much easier than I thought!   (Learn How to Cut and Clean Leeks.)

And what resulted from that second attempt was a cozy, heartwarming, and comforting bowl full of creamy vegan potato leek soup!

Vegan Potato Leek Soup Ingredients

Even though potato leek soup is typically made with heavy cream, you won’t miss it at all in this vegan version!

In fact, by using a healthier dairy-free cream you will feel so much better when you are finished eating.

Let’s take a look at the ingredients you will need:

• Leeks – Look for leeks that have more white part, are firm, and show no signs of yellowing.
  • Learn How to Cut and Clean Leeks if you don’t already know!
  • Do not substitute green onions for leeks in this recipe.  They are much more pungent and will overwhelm the dish!
• Potatoes – Yukon gold potatoes are the star of this recipe thanks to their super creamy and waxy texture.
• Garlic – An absolute must!
  • Garlic powder can be substituted, but is not recommended.
• Broth – A regular sodium vegetable broth was used when testing this recipe.
  • If you are trying to watch your sodium, feel free to use a reduced sodium broth.  You can adjust the salt to taste.
  • Vegetable broth, chicken broth, or chicken stock can be used interchangeably.
• Dried Herbs – A mixture of dried thyme and tarragon are used.  Feel free to use rosemary, basil, or oregano to change up the flavor a bit!
• Coconut Milk – Full-fat CANNED coconut milk is the replacement ingredient for heavy cream.
  • Aa lite coconut milk can be used if you’re watching your calories.  However, the soup will not come out nearly as creamy or flavorful.
• Lemon juice – Citrus helps to balance out the richness of the potatoes and coconut milk.
  • Make sure to add this at the end of cooking so it does not discolor or turn bitter.

Best Type of Potatoes

Yukon gold potatoes are the best type of potato to use in a potato leek soup.

Since they are a waxy potato they have a smooth texture that blends beautifully in creamy soups.

Unlike their starchier counterparts, Russet potatoes are not quite as creamy and will leave you with a thicker consistency.  (Think of a baked potato soup!)

If you cannot find Yukon gold potatoes in your grocery store, you can also use red potatoes instead.

And if you absolutely must, a regular baking potato, or Russet potato, will work.  But just know you won’t get the same marvelously creamy texture of a waxy potato.

Cook’s Tip: The smaller you cut your potatoes, the more quickly they will cook.  The larger you cut the potatoes, the longer they will take to fully cook.

Preparing Leeks

Before you start cooking your potato leek soup, you will want to prepare the fresh leeks.

To do this you will need to thinly slice the white part of the leeks and discard the dark green part.

Unlike green onions, the dark green part is actually quite bitter and will not taste good in the soup.

Once sliced, you will notice the leeks have quite a bit of dirt on them.

The easiest way to clean leeks is by immersing them in a big bowl of water.  Shake them around a bit until all of the dirt is removed.

How to Make Potato Leek Soup

Much like other creamy soup recipes, this vegan potato soup consists of a few basic steps.

Here are the step-by-step instructions for making potato leek soup:

1. Add the leeks and olive oil to a large pot or Dutch oven over medium heat.
2. Sauté leeks for 8-10 minutes or until they become soft and tender. (Step 1 above.)
3. Add crushed garlic and continue sautéing for 1 minute. (Step 1 above.)
4. Pour vegetable broth into the post, making sure to scrape the bottom to loosen up any loose bits. (Step 3 above.)
5. Add potatoes, dried herbs, milk, and salt.  (Step 4 above.)
6. Bring to a boil.  Reduce heat to medium and cover pot with a lid.
7. Cook for 12-15 minutes, or until potatoes are tender.  Turn off heat.
8. Blend soup until smooth and creamy.  (Read more below about how to make creamy soup.)
9. Stir in lemon juice and add additional salt, to taste.

Blending Creamy Soup

There are multiple ways you can blend soup to make it super creamy.

A handheld immersion blender, large blender, such as a Vitamix, and a large food processor all work great.

• Immersion Blender – This is the best method to use for this potato leek soup.  You’re able to blend a lot of liquid and it makes the soup super smooth.  Also, you do not have to transfer hot liquids from one pot to another.
• Vitamix – The second best blending method since it can hold a large volume of liquid.  Just be careful when transporting the hot liquid.
• Food Processor – The least effective and more time-consuming method since you will have to puree your soup in batches.  However, it will work if that is all you have!

Serving Potato Leek Soup

The healthy potato leek soup is all blended up and ready to eat, but what should you serve it with?

What to serve with soup?

• Toasted baguette – So good when slathered in a little butter or olive oil before toasting in the oven.
• Homemade croutons – Cube up some bread, toss in oil, and then bake until crispy!
• Crackers – These are great for dipping.
• Salad – A big kale salad would pair beautifully with these potato leek soup.

FAQs

What part of a leek do you use for soup?

The white and light green part is the portion of a leek that is used for soup.  Discard the leafy green part since it is rather bitter in taste.

How long does potato leek soup keep in the refrigerator?

Potato leek soup will last in the refrigerator when stored in an airtight container for 3-5 days.

Make sure you allow the soup to cool to room temperature before covering with a lid for the best flavor.

Can I freeze potato leek soup?

Yes.  Potato leek soup freezes well for up to 4-6 months when stored in a freezer safe container.

When ready to eat, thaw soup in the refrigerator for 1-2 days before reheating on the stovetop or in the microwave.
