Cauliflower Instead of Potato?
Most leek soups are cooked and blended with potatoes. For this recipe, I left out the potatoes and chose to use a large cauliflower instead. Cauliflower seemed more fitting to achieve the rich and creamy soup I was looking for.
But don’t let me rain on your potato parade. If you’re looking for a potato soup recipe to make (ya know, after you try this one) check out my potato corn chowder. It’s a creamy yet hearty soup loaded with chunks of potato. And just like this cauliflower leek soup it takes only one pot.
Don’t you just love those one-pot meals?
I sure do!
An easy one-pot soup
Talking about one-pot meals, this cauliflower leek soup is a chop and toss soup (toss in the pot that is). And the best part is, there are only 2 vegetables to chop: the large cauliflower head and the leek stalks.
After you chop ‘em, toss ‘em in the pot.
Simmer all that goodness together for 20-25 minutes then blend until smooth and creamy. Serve with your favorite toppings.
It doesn’t get much easier than that!
What are leeks?
I’ve always thought they looked like an oversized green onion. Which isn’t too far off since they are related to onions, scallions, and shallots.
The leek is a vegetable with a crunchy, firm texture in its raw state. The edible portion of the leek is the stalk (the portion between the root and green fan leaves).
Do leeks taste like an onion?
Leeks are milder and sweeter actually than onions. This means they are able to add a subtle onion touch to this cauliflower leek soup without overpowering the other flavors.
In other words, using 2 big stalks in this recipe yields the perfect flavor combination.

How to make Cauliflower Leek Soup
Step 1 – Prep
Start by chopping the veggies. Add them along with the broth and seasonings to your soup pot. Then give it all a good stir.
Step 2 – Cook
Simmer everything until the cauliflower has softened. When it’s done it should look something like the image above.
Step 3 – Blend
Now that the soup is cooked it’s time to blend. Grab your immersion blender and blend the cauliflower and leeks into a creamy soup. If you don’t own an immersion blender, you can carefully blend the soup in batches in a regular blender.
Serving this creamy, family favorite soup is all that’s left!
