This Potato Leek Soup is a fantastic soup recipe for fall! It’s so creamy and delicious, but wait, there’s NO cream!? That’s right folks! No cream! It gets its silkiness from a secret ingredient…cauliflower.
This soup also reheats beautifully, so you can make a big batch of it on Sunday to last throughout the week!

How do you make simple potato and leek soup?
The easiest way to make a simple potato and leek soup is to use the freshest ingredients possible, nothing frozen, because you’ll get the best flavor that way. In a large pot, you’ll sauté the leeks, celery, and onions in olive oil. Then add the potatoes, cauliflower, and chicken broth, cover, and simmer until the vegetables are tender. Then you’ll blend and season.
How To Make a Creamy Soup without Cream?
I also think the secret ingredient to a fantastic creamy soup without cream, is cauliflower. I’m convinced it is a “wonder vegetable”. There’s just so much you can do with it! And one of my favorite things to do with it is put it in soups as a replacement for cream. It’s the most genius little trick.
Cauliflower has the most incredible texture once cooked, which is why I like to use it. There isn’t much flavor, which is OK because the leeks, celery, onions, and garlic take care of that. The cauliflower’s real purpose is to deliver the texture. Cauliflower is also the secret ingredient in my Vegan Cream of Broccoli Soup.
If you have any leftover cauliflower and own an air fryer, you must try my Air Fryer Cauliflower recipe! It’s so easy and so delicious as a vegan side dish.
How do you cut leeks for potato leek soup?
For this soup, I like to cut the leeks into little wheels and not get any fussier than that. Especially since we are going to blend this soup so it really doesn’t matter all that much. If you have leftover leeks put them to good use in my Mini Leek and Cheese Quiche Recipe!
Your potatoes will cook quicker if you dice them into cubes. It also makes them easier to blend and will produce a creamier, silkier soup too.
I like to use chicken stock for potato leek soup because I think it creates a richer flavor, but to make a vegan potato and leek soup you can use vegetable broth.
Once the vegetables are tender transfer the soup to a blender.
Puree the soup in batches until smooth and creamy. At this stage, if your soup is too thick you can add some more chicken or vegetable stock.
After your soup is blended transfer the soup into a cleaned out stockpot.
Then season it with salt and pepper to taste and then ladle into some soup bowls.
I like to garnish this soup with freshly snipped chives and garlic croutons.
Can you freeze potato and leek soup?
Yes! This soup freezes beautifully. It will last for at least 2 months in the freezer. It’s best to freeze individual portions and then microwave to reheat.
This soup is a fantastic first course for a dinner party but also makes a terrific weeknight meal or lunch.
