Best Leek Soup Recipe

If you love potato leek soup, this is the recipe for you! I promise you won’t even miss the potatoes at all!

You will love the creamy texture of this no-potato leek soup recipe- made without heavy cream! The secret to making this creamy soup is the cauliflower. It is flavored with fresh herbs, garlic, and crispy green onions for a final touch!

There is one more secret ingredient- nutmeg! A pinch is needed to add flavor without overpowering the soup. We love nutmeg as a flavor enhancer! It is also added to bechamel when making Classic Italian Lasagna Bolognese with Bechamel Sauce.

Add homemade croutons or ciabatta bread as a topping. My personal favorite is serving it in bread bowls from our local bakery!

Leeks are healthy, nutritious, and from the same family as garlic, chives, shallots, and onions. Leeks are, however, sweeter than the onion. They are also milder than an onion or shallot. 

How to Make Leek Soup Step-by-Step with Photos

This leek soup recipe is an easy one-pot meal.

How to Make Leek Soup with Cauliflower

In a large pot on medium-high heat, saute the sliced leek in butter or oil until soft, about 8 minutes. Next, add the garlic and cook until fragrant.

Add cauliflower, salt and pepper, nutmeg, and herbs.

Add broth and give it a good stir.

Bring to a boil, cover, and turn down to a simmer for 20 minutes or until cauliflower is fork tender.

Allow soup to cool until lukewarm before blending. 

Use a hand-held immersion blender to blend the soup in the pot until smooth and creamy. Be careful when using a handheld blender in a bot of hot liquid. Alternatively, transfer to a blender and blend until smooth. Add more water or broth until desired consistency is reached.

Blend until perfectly smooth or desired consistency.

Crispy Green Onions

In a small saucepan on medium-low heat, heat oil and add chopped green onions. Saute until lightly golden brown and crispy. 

Serve soup in a bread bowl or with crusty bread, and top with crispy green onions, a swirl of creme fraiche, or coconut cream- if desired. Enjoy hot! 

Serving Leek Soup in Bread Bowls

It is optional to serve this soup in bread bowls. I love the beautiful presentation and delicious taste of the crusty bread and the creamy soup. This recipe is light, creamy, and delicious.

Washing Leeks

It’s important to wash leeks as they hold a lot of dirt between each layer. In this recipe, we use the white and green parts of the leeks for a smoother texture. Here is the proper way to wash leeks in a few easy steps.

1. Fill a large bowl with cold water and add sliced leeks.
2. Stir leeks in the water until all the dirt comes out from the insides of the leeks.
3. Use a colander to drain the leeks.
4. Pat leeks dry before using.

Stock or Broth for Leek Soup

For the liquid in this soup, you can use any stock or broth of your preference. See this post for making homemade chicken broth. Use any of the following.

• Chicken Stock or Chicken Broth
• Vegetable Stock or Vegetable Stock
• Water (adjust salt)
• Beef Stock Beef Broth
