A smooth, velvety cream of cauliflower soup with a handful of ingredients (no cream or potato). We love this pure and simple recipe!

There are a few things you need to know before diving into this creamy cauliflower soup recipe.

One: It only requires a handful of ingredients and about 30 minutes to make.

And number two is that it tastes as rich and satisfying as something that usually takes way more time to make.

It has a pure taste of cauliflower, accented by the delicate onion flavor of leeks.

You don’t even need to use stock as a liquid base (just water), and the addition of a good amount of grated Parmesan cheese adds a layer of savoriness that’s hard to hate on.

If you love the comforting soothing vibe of a classic creamy broccoli and cheese soup, this recipe is one to try.

The texture of the soup is lusciously dreamy-creamy but it doesn’t have any flour, cream or butter. 

For me, that translates into a soup without that gloppy, pasty texture you sometimes get when you make one thickened with a milk and flour base.

Actually, this is a (mostly) dairy-free soup recipe — with the exception of the Parmesan cheese in there, of course. 🙂

This recipe is a good one for people following a Paleo, Whole30 or Keto lifestyle.

Feel free to omit the cheese to make this a creamy vegan cauliflower soup.

The way to achieve a light, smooth texture is to use a high-speed blender or a handheld blender.

I like to keep things simple in the kitchen, and that applies to all the gadgets and cooking-related doodads that are just too easy to collect.

But!

I have to admit that my whole cooking life would be completely different without a few electric appliances, and my blender is one of those.

I bought a Vitamix almost ten years ago.

Yes, it was quite an investment, but it’s still going strong, whipping up smooth pureed soups like this one, as well as daily smoothies and sauces.

Not mentioning that to say you need a fancy blender to make this soup — not at all!

In fact, it’s really the humble cauliflower you have to thank here.

Cauliflower is a perfect stand-in for carbs, to the point where we’ve become obsessed with turning cauliflower into pizza crusts, using it as a low-carb substitute for rice or simply roasting it to put together a bomb healthy salad.

Along with its other virtues, cauliflower makes magical purees that have a lovely velvety texture.

How to make creamy cauliflower soup

The process for making this soup is pretty efficient.

First, sweat the some leeks in olive oil.

Then add your cauliflower florets along with water and seasoning.

If you prefer, you can use broth instead of the water. This is an especially good option if you plan to make this without the Parmesan, because it will add the salty umami in place of the cheese.

When the cauliflower is tender, use a blender to puree it until very smooth (in two batches). 

The other option is to just immerse a handy stick blender into your pot and blend away.

For a soup that comes out with the perfect texture, follow the ingredients ratio carefully, which is 5 cups water to the florets from  a large (2-pound head) of cauliflower.

Servings 6 servings

Ingredients

  • 3 tablespoons extra virgin olive oil, plus extra for serving
  • 2 leeks, white and light green parts chopped
  • 1 large cauliflower, about 2 pounds, cut into florets
  • 1/4-1/2 teaspoon red chili flakes, to taste
  • 5 cups water
  • 2 teaspoons kosher salt
  • 1/2 cup grated Parmesan cheese or Pecorino Romano cheese, plus additional for serving
  • 1/2 cup chopped fresh parsley

Instructions 

  • Pour the oil into a large (4 or 5 quart) saucepan or Dutch oven. Place over medium low heat and add the leeks. Cover the pan, lower the heat and cook about 5 minutes, or until the leeks become meltingly tender without coloring.
  • Add the cauliflower to the pan along with the chili flakes, water and salt. Bring to a simmer, then partially cover and until cauliflower is soft, about 25 minutes. Remove from heat and let cool 10 - 15 minutes.
  • Stir in the cheese and puree the soup in a blender in 2 batches or with an immersion blender until it's very smooth.
  • Sprinkle with parsley and additional cheese before serving, and drizzle olive oil over each serving.

Notes

This recipe is a good one for people following a Paleo, Whole30 or Keto lifestyle.
Feel free to omit the cheese to make this a creamy vegan cauliflower soup.
If too much liquid evaporates during cooking, add more little by little to achieve the consistency you like, then check for seasoning (more water will dilute the flavors).
For a delicious garnish, add a swirl of pesto to serve. I love this Walnut Parsley Pesto.
