Simple Cauliflower Soup

This simple cauliflower soup is made with just five ingredients, including salt! It's a quick and easy weeknight meal that's easy to dress up or down. Dinner is served!

  • Prep time: 10 minutes
  • Cook time: 15 minutes
  • Yield: Serves 4



1 Cook cauliflower florets in salted water: Bring 1 quart of water to a rolling boil in a medium-sized pot. Add 2 teaspoons of salt to the water.

Add the cauliflower florets, and cook until cooked through, about 4 minutes. Use a slotted spoon to remove florets to a bowl. Reserve cooking water.

2 Purée cooked cauliflower: Working in batches, fill a blender half-way with cooked cauliflower, add enough cooking water to the blender bowl so that it comes up a quarter of the way. Purée until smooth. You want the consistency to be that of soup, so if you need to add more water, do so.

3 Add salt and butter: or each blender batch, add salt and butter to taste (about 1/2 teaspoon of salt, and about a tablespoon or more of butter for each blender batch). Since you are using only lightly salted cooking water for a base, not stock, you will need to salt this more than you would otherwise.

4 Serve: Serve immediately into bowls. Drizzle olive oil over the top and sprinkle with chopped chives.

    I made a curry cauliflower soup…very similar, though it added a chopped onion (sautéed in a bit of oil) and a chopped potato. And of course curry powder. Trying to get as many cruciferous vegetables as possible into my diet. This is a nice addition.

    It was amazing. If you add ham, parmasian cheese, and chedder cheese it is heavenly.

    So simple yet so – just made this-I added half a teaspoon of clarified butter to replace butter/ olive oil- and it was delish! Thank you for this wonderful recipe


  • DS

    This looks amazing. Has anyone tried to make it at all ahead of time, either completely, or at least cooking the cauliflower ahead? I would need to make it a bit earlier in the day but it says to serve it immediately when it’s finished. Thanks.

    Hi – I’ve never commented on a recipe before but the combination of ease and yummyness meant I had to! Great recipe – I ditched the butter and added feta, and it was delicious (I don’t eat dairy). Thanks!

  • Janet

    Delicious and light!

  • Geraldine

    Just made this soup, my daughter and I both loved it! So simple, so quick, so delicious. I added too much of the cooking liquid, so I put in a splash of heavy cream which finished it off nicely, but next time I will use less liquid. Will now follow you on pinterst, thanks.

    We had this for supper last night and it is absolutely incredible!!!
    Thank you!

    I love this soup, and I like to add a bit of bacon crumbled in, and shred some old cheddar on top. I’ve also followed the same steps but with broccoli instead of cauliflower and it works really well.

    I made this for lunch today with parsely instead of chives, with added bacon and shredded cheese. It was so yummy!!!

    I made it the other day as my first meal to break my week long fast. Thought it would be something easy for my stomach (minus the salt and butter). It was simple yet delicious! I added the salt and butter for my boyfriend and he loved it too.

    We made this for lunch yesterday. The instructions to “Add 1 tablespoon of salt to the (1 quart of) water” — which you then reuse as the soup base — made this much too salty. Is that measurement correct?

    It was the correct amount, assuming you are using unsalted butter. I’ve adjusted the recipe to specify unsalted butter and to start with a little less salt since some people are more salt sensitive than others. With unsalted butter and 1 Tbsp to start I ended up having to add more salt to the soup. ~Elise

    Wow, I just made this for lunch, and not only was it delicious, but it was quick and easy to make. The drizzle of olive oil and sprinkle of chives makes the soup look gourmet. I crumbled some yummy blue Stilton cheese on top (just got my crock in the mail last week), and talk about a divine meal! I always appreciate (and keep) the simple recipes the most, and in this economic climate, also the inexpensive ones!

    Hi Elise, this looks really nice! I love cauliflower, and this was very easy to make. I figured if this works with cauliflower, it should work with broccoli as well, so I went and made both. Combine both in one bowl for an awesome presentation. See my blog entry for a picture. :-)

    Related item from Laurie Colwin (R.I.P.) Chunk up a head of brocoli, a couple of spuds, 3 or 4 garlics and an onion is you want in a pot with water (or veggie stock) to almost cover. Add curry powder to taste – big Tbs. Cook till quite soft, buzz in blender with 1 small yogurt. Serve hot or room temp. That’s Laurie – simple and yummy.

  • paulie

    I substituted the butter with Olive Oil, delish!

  • amy

    Even better with a sprinkle of blue cheese and fresh parsley!

  • Sarah

    And here I was wondering what to do with the head of cauliflower I bought at the grocery store last night…do you think this soup would freeze well?

    No idea. But the soup is so easy to make, you could easily make one serving at a time. ~Elise
