Author Notes: I keep trying different variations of cauliflower soup since this is one of my favorite vegetables for a soup in the fall and winter. It so versatile and works well whether I pair it with chipolte peppers in adobo sauce and manchego cheese or just with cream and some parmesan. I usually simmer the cauliflower in chicken broth and vegetables before pureeing it, but wanted bring out the flavor of the cauliflower more for this one and chose to roast it instead. Since the resulting flavor was more pronounced, I had more leeway in stirring in a chimichurri without overpowering the cauliflower flavor and added a drizzle of creme fraiche incorporating a roasted pobano pepper and garlic. I served this as the first course at a dinner party last weekend with much success. One guest confessed that he had never cared for cauliflower but loved this soup. TheWimpyVegetarian

Food52 Review: ChezSuzanne's technique of roasting cauliflower before simmering it gives this soup a rich, caramel undertone, and the touch of cream and parmesan lend just the right amount of richness to the velvety cauliflower and leek purée. The chimichurri sauce and poblano creme fraiche require a bit of extra time (and blender cleanup), but it's worth the effort; this is a perfect weekend project for when you have an hour or two to lose yourself in a recipe. We recommend using a small head of cauliflower for the right texture. - A&MThe Editors

Roasted Cauliflower Soup

  • 1 head cauliflower, sliced, including the core
  • 3 tablespoons unsalted butter
  • 1 tablespoon olive oil
  • 1/2 yellow onion, diced
  • 1 leek, light green parts only, diced
  • 1/2 teaspoon garlic, chopped
  • 2 ribs of celery, diced
  • 1 teaspoon salt
  • 1 cup chicken broth
  • 2 1/2 - 3 cups water
  • 1 tablespoon parmesan cheese
  • 2 tablespoons heavy cream
  1. Preheat the oven to 350F. Place the slices of cauliflower on a dry cookie sheet and roast until tender, about 15-20 minutes.
  2. In a large heavy pot, heat the butter and oil until hot. Saute the onion, leek, garlic, and celery in the butter oil mixture until soft and very aromatic. Add the salt. Add the roasted cauliflower and toss with a large spoon until the cauliflower is completely covered with the onion mixture. Cook for another 2 minutes.
  3. Add the broth and water. Bring to a boil and then simmer for 5 minutes. Puree in a blender until fairly smooth. If you want it completely smooth, you'll need to use a food mill, but having some texture to it adds to the rustic nature of the roasted flavor. Pour back into the pot and reheat to a simmer. Add the parmesan cheese and cream. Stir in the chimichurri sauce until well incorporated. Serve hot in soup bowls. Drizzle some poblano creme fraiche over the soup.

Chimichurri Sauce and Poblano Creme Fraiche

  • 1 serrano chili, seeded, coarsely chopped
  • 2 garlic cloves, peeled and coarsely chopped or smashed
  • 2 cups cilantro leaves
  • 2 tablespoons mint leaves
  • 5-6 tablespoons olive oil
  • 1/2 tablespoon fresh lemon juice
  • 1/2 teaspoon kosher salt
  • 1 poblano or pasilla pepper, roasted, peeled and seeded
  • 2 garlic cloves, peeled
  • 1/8 teaspoon kosher salt
  • 1 tablespoon olive oil
  • 2 tablespoons heavy cream
  • 2 tablespoons creme fraiche
  • pinches sugar
  1. To make the chimichurri, place the first 7 ingredients in a blender and process until finely chopped. This is a very versatile chimichurri - I've used it on pork, in omelets with Manchego Spanish cheese, and in this soup.
  2. To make the poblano creme fraiche, combine the next seven ingredients starting wtih the roasted poblano or pasilla pepper in a blender and process until very smooth. Once smooth, I put it into a squirt bottle that allows for different pipe tips, and squeeze the creme fraiche on the soup. This creme fraiche also works well as a spread on sandwiches.

I completely see why this recipe is a winner. I got to do two new things; dry roast veggies (I've always splashed in oil....I enjoyed the effect...somehow toastier without the oil) and make a chimichurri. My husband enjoyed the soup sans chimichurri (I took some out knowing he is not fond of cilantro), but I really loved the freshness and bit of heat it brought, And the poblano cream....who couldn't love that. Thank you for the celebration of flavors in this dish.

This was good! I added some extra onion and celery, extra veg broth (instead of chicken), some extra salt and pepper, then used coconut cream instead of dairy cream. I left out the sauce and crème fraiche, being short on ingredients. Next time I will try the crème fraiche. I plan to use coconut cream with that too.

Why is it that some vegetarians think that the inclusion of Chicken Broth is OK? That is NOT vegetarian by nearly anyone's definition. Why not simply cook this on a veggie broth? I'll be trying it that way.

11 months ago TheWimpyVegetarian

You're correct, but this isn't intended to be a vegetarian recipe. If you are vegetarian, by all means use vegetable broth, or even water. Both will work fine, although I think a vegetarian broth will provide more flavor than water.

I have just made this soup and it was incredible! Though I should add that I modified it a bit as wasn't in the mood for adding cheese and heavy cream (it is late night in Europe as I am typing). Instead of water I used my homemade vegetable stock. And what I can I say, wow, wow, wow! I have made similar soups before, i.e. roasting the veggies before they go into the soup and in my opinion that makes a big, big difference. Will definitely make this again!

Way to much work for this soup. The color does not look like the photo after adding the chimichurri. the whole thing turned green. The taste is kind of off too. I'm wondering how this was the "contest winner"???


about 1 year ago beccaoco

I'm bummed I spent so much time on this. UGH.


over 1 year ago gillianknitsalot

I loved the base but I thought adding the entire amount of chimichurri was too much; I could no longer taste the cauliflower base. Next time I think I'll add the chimichurri slowly to taste & use the rest for a skirt steak to serve alongside. The poblano creme fraiche was AMAZING!

Made this tonight and it was really yummy! My Russian (meat and potatoes eating) husband loved it as it reminded him of potato soup. I had a Dr Evil laugh in my head as he was getting a hefty servings of organic cruciferous veggies! Will definitely make this again - thanks!

over 1 year ago TheWimpyVegetarian

hahaha! I have the exact same laugh when I successfully hide tofu in a casserole, and my husband Carnivorous Maximus raves about how good it is...LOL.

I made this last night and it was delicious! I skipped the step of making a separate chimichurri sauce and instead added chilis, cilantro, garlic, lemon and mint to the soup prior to blending. I did make the poblano crème fraiche which I stirred in when serving, yum!

So glad you liked it!! Thanks for letting me know :-)

I served this at dinner with friends and it was a huge hit. It's not hard to make, just requires washing multiple dishes. I like that it can be make early in the day and assembled last-minute once the base soup is re-heated.

So glad you and your friends liked it so well!

I have made it. I just thought it was a lot of work and would not do it again. I wouldn't have commented if I hadn't made it.

Why comment if you haven't MADE the RECIPE? ZZZZZZZZZZZZZzzzzzzz

Good but not that good!

Super excited to make this soup after reading the reviews. Tastes weird, so not my favorite. This recipe is quite a bit of work and mine was really thick even after thinning it with water. The poblano/creme fresh combo is the same color as the soup so mine was not as pretty as the photo. Just kinda a mess I'm sorry to say.

almost 2 years ago TheWimpyVegetarian

I've made it dozens of times now, and really sorry it didn't work for you. Thanks for letting me know!

Thanks so much!!!

This soup is so fantastic. Someone served it to me at a dinner party and I practically jumped across the table to get the recipe from him, then made it myself the very next day. I subbed parsley for the cilantro in the chimichurri because I had it on hand and it was still delicious!

over 3 years ago TheWimpyVegetarian

Wow! Thank you so much!! What a wonderful way for me to start my day with your generous comment. I'm so glad you enjoyed it so much!!!


over 3 years ago merrymaker

So so so good! Man. Delicious!

I used veggie broth and plain Greek yogurt instead of heavy cream and welll, it might just be my favorite soup ever.

over 3 years ago TheWimpyVegetarian

I'm making it with yogurt next time too! Thanks so much for your feedback - I'm so glad you liked it so much. You made my day!

I made this the other night and loved it - who knew chimichurri would be so good with cauliflower! This is definetly going on the repeat list.

over 3 years ago TheWimpyVegetarian

It IS surprising what a great match they are - I agree! For something simpler with this combination, try slicing the cauliflower in thick slabs and roasting it and then drizzle the chimichurri on it to serve. I'm so glad you loved this soup. Thanks for letting me know!

We loved this soup, but I only had a purple cauliflower at home (maybe it was broccoli romanesco? it came in my CSA box without a list last week) and I found: the color was a bit weird, to be expected, but also, the chimichurri was slightly overpowering. Anyone else have that? Could be,since there is no specific weight for cauliflower given, that mine was a bit light and I needed to ramp it up for more cauli flavor. It was still yummy, and I'll do it again. I,too,used veg. stock instead of chicken, but like the idea of light sour cream.

Just seeing this for the first time now - just delicious. Will make soon!

Thanks healthierkitchen!! I'd love to hear what you think if you make it!
