Paul Bertolli's Cauliflower Soup
This is really all there is to it: a cauliflower and an onion.
Slice that onion thinly.
And floret that cauliflower.
Olive oil on the verge.
Sweat the onions, but don't let them brown.
First you stew the cauliflower in 1/2 a cup of water, then when it's tender, you add a whole bunch more water. Sounds grim, doesn't it?
Scoop it into a blender and watch it dissolve into soup.
Covering hot things in blenders with a towel is always a good idea to prevent surprises. Nobody likes cleaning soup off the ceiling.
This photo is entirely unnecessary -- we just thought it was cool.
The soup will continue to thicken up and grow more flavorful as it sits for 20 minutes.
You can go bare.
Or give it a little love, with a swoop of olive oil and twist of black pepper.
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

Cook time: 1 hrs 13 min
-
3
tablespoons olive oil

1
medium onion (6 ounces), sliced thin

Salt, to taste

5 1/2
cups water, divided

Extra virgin olive oil, to taste

Freshly ground black pepper, to taste
- 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.
- 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.
- 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.

I’ve had my eye on this recipe for awhile.
Now I’m kicking myself for not trying it sooner. It is so very good in all its simplicity. Yes, you can add all the other things but if you just follow the recipe, it’s delicious! (I used a stick blender with success)
I was skeptical that this would be flavorful enough. I also balked at what seemed to me the slow extra steps. I took only a few shortcuts (coarse onion chop, pressure lid, stick blender in pot, no rests), but must say I’m extremely impressed how creamy the texture and how each ingredient shines clear and clean. Hard to believe no dairy. A genius recipe. Use great olive oil: a real spotlight for it.
I could not believe how delicious this was! We devoured it! It will be my go-to anytime I have a cauliflower "on the brink". I sprinkled a little nutritional yeast on top and my husband used some parmesan--both were great. Will definitely make many times in the future. Thanks!
Made this today with good results although I did add a few things. Put in hot pepper flakes with the the onion. Roasted the cauliflower before adding to tbe pot along with a few cloves of garlic also roasted. the cauliflower went to the pot with the roasted garlic, chopped fresh sage and thyme and zest of half a lemon. Will definitely make again and try adding a cup of concentrated chicken stock. Thanks for the recipe!
Delicious!
I made it as the recipes suggests and the flavor of cauliflower and onions shine. I had it with a toasted baguette slice with butter, on the side, and a cup of cider. Perfect.
We loved it!!!! give it another try!!!!!
My friend made this cauliflower soup and used chicken stock in place of the water and also grated in some cheddar cheese to the soup which picked up the flavor overall!!!!!!!
This is about the blandest thing I've ever made. The only way I could stomach it is to add a lot of salt.
Very delicious. Amazing that something so satisfying is made without cream or butter.
I just made this soup and it's a bowl of silken deliciousness! Even before the 20-minute resting stage it was perfectly thick. I added more salt while it was simmering since that's when one would typically add salt to a soup, and I only added four cups of water and skipped the additional 1/2 cup. I finished it with few drops of lemon juice along with the olive oil and pepper, and added a twist of ground sea salt. If you know French home cooking you'll get what this recipe is all about. Simplicity from just a few ingreds. This tastes like something I would be served at my Aunt Madeleine's table.
I use vegetable stock and add bay leaves. SO good! I seriously eat it at least a few times a week.
Great idea! I was thinking of bay when I made it.
Mindless drones lend my your ears..........recipes are a guide for the intelligent cook and nothing more.(mic drop)
For me it was bland. Next time I would add some stock, maybe turmeric to help it along.
This soup is SO good, its flavors are so delicate coming from a few simple, fresh ingredients. I'm a fan.
Pleasantly surprised. Super simple, which is a huge plus for me, and not so bad at all (this coming from a someone who is married to a vegan). A gem of a recipe.
Without getting distracted by all the comments below....I love this recipe. Thank you Kristen for finding and sharing it!
I'm a fan of the soup as is, not at all a detractor. I just suggested some other possible uses, as well as a semantic thought that might explain why it disappoints a very few.
I am sorry if I hurt anyone's feelings. That seems to be a trend these days. My issue with the negative comments were that they blamed the recipe rather than the execution. Chef basically gave us all a gift: Do you want to wow your guests without going stupid>>>Well here it is-no truffles, not exotic mushrooms-just an onion, a head of caulaflower, some water and whatever you want to add. Detractors want to say it is watery, not salty enough and useful as a daily water supplement. And untrained "cooks" come on this site and trash the recipe rather than asking, "what did I do wrong?" Sorry, but this site should be for thoughtful discussion.
Thank you, Jim. You just addressed my pet peeve in recipe comments.
Totally agree with Glenn and just the simplicity of the recipe makes it so special.
Yes, I really love this recipe as well as the many recommendations in this thread to further deepen or layer the flavors. It's also a wonderful base. I've also used the same template to make a mushroom or broccoli broth -- and I continue to think what puts some people off are the expectations that cone with the word 'soup.' Think of it as a broth or even a warm cauliflower drink and perhaps for those now feeling something missing you'll be satisfied. Another use: I don't drink as much water as I should. Here is a very nutritious and filling way to get more hydration.
