Author Notes: This soup might seem plain, but trust us. Paul Bertolli, who was at the helm of Chez Panisse and Oliveto for over 20 years, knows exactly how to make a vegetable become the best it can be. This recipe comes from Cooking by Hand, Bertolli's IACP award-winning book of recipes and essays, and makes for a soup that's delicate, sweet, and smooth as a flannel scarf.Genius Recipes

Serves 8

  • 3 tablespoons olive oil
  • 1 medium onion (6 ounces), sliced thin
  • 1 head very fresh cauliflower (about 1-1/2 pounds), broken into florets
  • Salt, to taste
  • 5 1/2 cups water, divided
  • Extra virgin olive oil, to taste
  • Freshly ground black pepper, to taste
  1. Warm the olive oil in a heavy-bottomed pan. Sweat the onion in the olive oil over low heat without letting it brown for 15 minutes.
  2. Add the cauliflower, salt to taste, and 1/2 cup water. Raise the heat slightly, cover the pot tightly and stew the cauliflower for 15 to 18 minutes, or until tender. Then add another 4 1/2 cups hot water, bring to a low simmer and cook an additional 20 minutes uncovered.
  3. Working in batches, purée the soup in a blender to a very smooth, creamy consistency. Let the soup stand for 20 minutes. In this time it will thicken slightly.
  4. Thin the soup with 1/2 cup hot water. Reheat the soup. Serve hot, drizzled with a thin stream of extra-virgin olive oil and freshly ground black pepper.

This was so delicious and simple. I am surprised at the negative comments and wonder if it has to do with the type of onions used or the quality of the olive oil, because I served it to a foodie group and everyone loved it. I already got another cauliflower to make it again!

This recipe is boring and tasteless. Carmelize those onions! Add flat-leaf parsely, garlic, red pepper flakes, lots of salt and pepper, chicken or vegetable stock instead of water and touch of cream. VERY important: you need two head of cauliflower, not one, to get a true cauliflower taste. And then you have a tasty soup that's worthy of Chez Panisse. ;)

Thanks for the hints! My friend tried this and said it was bland and thin. Instead of plain water I'm going to do half veggie broth and 1/2 almond milk and perhaps add a potato for a little more thickness.

Love this soup, I never understood cooking the cauliflower for so long, tho. I cook the onions a long time, then steam the cauli til it's just soft enough to blend. Pour in more water to stop the cooking let it cool a bit to blend and strain. . If you have a nice fresh cauli, dont let it get all cabbagey by cooking for 40min!

We made this as our starter for Christmas dinner and it was really delicious and so simple. I was worried it would be bland since the recipe was so easy. I think cooking down the onion added a lot of flavor. And we may have used a little less water since we like a thicker consistency soup.

I'm with Tbird and Nancymk - after making this twice, I found it to be consistently and exceptionally bland. Adding things to try and make it not bland would only serve to glop it up.

The soup is so perfect and so easy it's become a weeknight staple. Plus it's been my go-to recipe for my friends with babies (and even they are fans too). I've only ever added a whips of truffle oil or black maldon salt to garnish at the end because I'm too paranoid to muss up perfection. But I may try to sub the water for homemade stock next week. Folks who've done this, what's your gauge?

Such a delicate and beautiful soup! I cooked the onion slices in coconut oil and pork lard and halfway through I added chopped garlics and some pine nuts. I also used store-bought chicken broth (Maggi to be exact). The end result was silky, nutty, and delicious soup. Next time I'll try with homemade homemade vegetable stock or dashi.

Substituted low sodium chiken broth for the water and also added a little heavy cream for richness. Drizzled a little Extra Virgin Olive oil and a dollop of Creme Fraiche. Also added seasoned croutons. Was trying (successfully) to duplicate a meal I had in Aubeterre, France.

I'm not sure how to remove myself from getting an email every time anyone comments on this thread.
Any ideas?

I have not made this soup yet but I'm thinking a drizzle of white truffle olive oil sounds lovely. Now I'm going to have to go out and buy some tomorrow!

Well here's a first. A negative review. Followed directions exactly, and got a bland soup. I've added lots of salt and pepper to give it some flavor. Bummed, as I was expecting a great soup. Nancy McK... I'm in agreement with you. I think Chicken Stock would have been better, but not sure if that would have done it. Oh well, can't win em all and it was a low cost investment.

Now... what to feed my kids, because they're still hungry!! :)

I am making this soup again because it is so good. I used all chicken broth instead of water and toward the end threw in a rind of Parmesan cheese. Delicious!

I made this soup again last week, for about the fourth time since first finding the recipe. It was incredibly delicious. Used fresh cauliflower from the greenmarket. Otherwise followed the recipe to the letter. Thanks again for the recipe!

I think it's hilarious that you keep printing this recipe. I made it once and thought it was bland and boring. Everyone kept raving so I made it again. And guess what? It's bland and boring.

This soup was absolutely delicious. I made a few modifications because I don't have enough cauliflower, but it turned out great. To start, I added 2 garlic cloves halfway through cooking the onions. I used a purple cauliflower and two small heads of super sweet corn. IT was perfect combination; corn and cauliflower. For a small kick, I added a pinch of cayenne and 1 tsp. of crushed red pepper!

Just made this soup. Based on the comments think it will be perfect for my friend who just had quite major surgery that included her abdomen and whom I'll be taking care of when she comes home from the hospital. Can this soup be frozen and then reheated?? Many thanks, K.

I haven't tried it myself, but I'm pretty certain freezing and reheating would be just fine. So glad you liked it -- hope your friend does too.

Instead of pepper, add some dukkah. Delicious!

I have made this soup @ least 1 a week sometimes more. Hands down my favorite soup ever. Have turned so many people on to this recipe too. I use boxed Safeway Organic Chicken Broth in place of the water and also throw in a shallot w/ the onion.

It's so tempting to pair another ingredient or spice with a basic pureed vegetable soup, but in the case of cauliflower, it doesn't get better than this - a pure, simple, single ingredient shining. I make this recipe over and over again, year-round. Using great olive oil elevates it. I converted to a Vita-Mix blender a while back and now it's even better - silky and almost decadent. Like cauliflower in a sexy slip.
