Roasted Cauliflower Soup with Coconut and Turmeric
Roasted Cauliflower Soup with Coconut and Turmeric. This healthy cauliflower soup recipe is flavored with Thai chili paste and coconut milk!
One of my favorite methods to enhance a soup is to incorporate roasted vegetables. It adds a little something, something. This roasted cauliflower soup with coconut and turmeric is a perfect example.
Cauliflower florets, tossed with ground turmeric, are roasted until lightly caramelized and crispy. Truthfully, you could serve those as a side dish on their own. Roasting is especially helpful for more naturally bland vegetables like cauliflower, broccoli, or other root vegetables. Similar to potato, cauliflower also happens to produce an exceptionally creamy soup texture (which is why you often see it as a base for cheese sauces, etc.!) without adding starch or heaviness.
This cauliflower soup recipe is an adaptation from the beautiful cookbook, Clean Soups by Rebecca Katz. My mom (who loves soup just as much, if not more than me!) recently gifted it to me, and I can’t wait to dive into it this coming season. The book does a fabulous job of breaking down soups into a few key building blocks (fat, aromatics, broth, herbs and spices, etc.). Once you understand these general building blocks, you can start to create your soups from scratch!
This blog is filled with quite a few cauliflower recipes, but this might be one of my favorites.
The most frequently asked question that I receive is, “what type of food do you most enjoy making?” Cooking has been part of my professional life for almost seven years, so it only makes sense that people want to know what gets me most excited!
Unfortunately, the answer isn’t quite as conversation-starting as one might think. Homemade pizza and pasta are certainly up there, but that’s in large part due to the satisfaction received from eating them (no, really, it’s sometimes that simple). But what do I enjoy making the most? That is a much harder question. Believe it or not, soup is one of my favorite things to make, period.
Yep, soup. I love the mindless chopping, dicing, and prep work that goes into a great bowl of soup. The comfort and hearty satisfaction it brings. The accompaniments (a hearty salad, great crusty loaf of bread, great cheese) it encourages. But, really, the best part about it? Soup lends itself extremely well to experimentation in the kitchen. If you’re uncomfortable improvising or you want to start putting your own spin on recipes (rather than strictly following them), start with soup.
Not only is soup forgiving by nature, but it can be flavored, adjusted, and enhanced in so many simple ways. Can’t eat dairy, but want to achieve a luscious creamy soup nonetheless? Substitute the cream with full-fat coconut milk or achieve the same effect with a starchy root addition like potato. This creamy roasted acorn squash and sweet potato soup is one of the most popular recipes on this blog, and it just happens to be vegan.
Want to put a international twist on a classic? Substitute traditional spices and herbs with spice blends like garam masala, ground ginger, curry powder, or in the case of today’s recipe, Thai chili paste. Even the simplest of additions, like grated ginger or freshly squeezed lemon or lime juice, will completely elevate and change a soup’s flavor profile.
Better yet, puree a can of drained cannellini or garbanzo beans and add them halfway through. You’ll be adding protein and heft. Or get inspired by the season! Substitute yellow onion with creamy leeks, carrots with parsnips, sweet potato with your favorite winter squash. My biggest tip for soup?
Never underestimate the power of salt and acid. If your soup creation tastes a little flat, try adding a generous pinch of kosher salt or a squeeze of lemon or lime (lime is my preferred acid for soup, it is more delicate). It can make or break a soup.
In my kitchen, soups can be used for practically any occasion. This roasted cauliflower soup is in celebration of Cynthia, the talent behind the beautiful blog Two Red Bowls.
A few days ago, Cynthia gave birth to an incredibly adorable baby boy named Luke, and a bunch of internet friends are coming together to celebrate the news with….you guessed it…foods made or served in bowls! So fun and cute, right?
With the incredible World Series victory by the Cubs last night, yesterday’s (literal) toast in celebration of Ashley, and today’s bowl party in honor of Cynthia, we’ve had one heck of a week. Cheers! Have a great weekend friends!
Roasted Cauliflower Soup with Coconut and Turmeric
Equipment
Ingredients
- 2½ to 3 lbs cauliflower, about 2 small heads cut into medium florets
- 3 tablespoons extra virgin olive oil
- ¾ teaspoon ground turmeric
- kosher salt
- freshly ground black pepper
- 1 medium yellow onion diced
- 2 cloves garlic minced
- 2 medium carrots peeled and diced
- 2 stalks celery diced
- 2 teaspoons Thai Roasted Red Chili Paste
- 1 quart (4 cups) low-sodium chicken broth plus more if needed
- 1 (15 oz) can full-fat coconut milk
- 1 tablespoon grated fresh ginger
- ½ juicy lime plus more if needed
- small handful cilantro leaves finely chopped
Instructions
- Preheat the oven to 425°F (218°C). Line a sheet pan with parchment paper. In a large mixing bowl, toss the cauliflower florets with 2 tablespoons extra virgin olive oil, ½ teaspoon ground turmeric, ½ teaspoon Diamond Crystal kosher salt, and freshly ground black pepper. Roast for 20 to 25 minutes, flipping the florets halfway through, or until tender and caramelized.
- Meanwhile in a large soup pot, heat the remaining tablespoon of olive oil over medium heat. Add the chopped onion, remaining ¼ teaspoon turmeric, and a pinch of salt, and sauté, stirring occasionally, for 3 to 4 minutes or until softened and slightly translucent. Add the garlic, carrots, and celery, and sauté for 10 to 12 minutes, stirring occasionally, until the vegetables are lightly caramelized. Add the Thai chili paste and stir until the vegetables are evenly coated. Pour in ¾ cup (180 mL) chicken broth, scraping the bottom of the pan to loosen any caramelized bits, and continue to cook until the liquid is reduced by half. Add the remaining chicken broth, grated ginger, and the roasted cauliflower to the pot. Bring to a boil, reduce to heat to a low and simmer the soup for 10 to 15 minutes, or until the vegetables are very tender.
- Carefully transfer the soup in batches to a high-powered blender, such as a Vitamix, and puree until smooth – adding additional broth if necessary. Transfer the soup back to the soup pot, place over low heat, and whisk in the coconut milk. Stir in the lime juice and season to taste with salt and pepper.
- Serve hot and garnish with cilantro as desired.
Tips for Success:
- Once the soup is pureed, be sure to taste it before serving. If it seems flat in flavor, the soup most likely needs a few good pinches of kosher salt or another squeeze of lime juice!

Really delicious soup. Rich and silky smooth, it is beautiful to look at and even better to eat. I made this soup for the first time today. I followed the directions exactlt and got excellent results. If I were to do anything different next time, and there will be a next time, I might add a dab or two of Thai paste to the roasting mix. Other than that … cant improve on perfection.
Great recipe. Straight forward and very tasty!
I tried this recipe after having something similar in a restaurant. WOW! It was equally as good, wholesome and full of flavour, a meal in itself. Can’t wait to make it for dinner guests. This will definitely make it onto my all time favourite list of home made soups
Today was a drizzly fall day and I had a completely unscheduled day, so I decided it was a perfect soup making day! I had a large head of cauliflower in my fridge that was screaming “use me.”
I had saved this recipe sometime back for just today I guess because when I checked the ingredient list with my fridge and pantry for matches, I had every single item. Serendipity.
Fairly straightforward recipe, above average results! I loved the creaminess, and the flavors were in complete harmony with my mood, and the weather.
I’ll have another bowl this evening with a grilled cheese sandwich and a nice Pinot Grigio while I watch election results.
Love your recipes!
Thank you so much Linda! Really appreciate that you came back and left a detailed review. It means a lot and is always helpful to others too.
can I use curry powder instead of thai curry paste?
You definitely could but the flavor will be different (they’re not equivalent) and I can’t advise on a specific quantity – every curry powder is vastly different – without testing it.
Beautul soup. Thank you for posting. A vitamix is a must in order to get a very creamy texture. I initially used an immersion blender but the soup was grainy, so I transferred the mixture to the vitamix and it came out perfect. I may add some roasted corn next time.
I’ve made it as written and loved it. Have also made it by adding the carrots to the roasting pan w/the cauliflower, then adding the onion and celery to it with 15 minutes left. And now I want it at least weekly. Sheer perfection.
Wonderful! Love to hear this.
Hi! I love this soup so much! Quick question, by two stalks of celery… do you mean two ribs or two entire bunches? THank you!
Oof!! This is a good question and probably has led to some confusion in other recipes – by stalk, I mean two ribs, but I can see that some people might refer to a stalk as an entire bunch, so I’ll need to do some more digging and might need to edit some recipes! Thank you for bringing this to my attention.
I made it almost exactly as written, except I used Huy Fong jarred chili sauce w/ a splash of vegan fish sauce (hubby is deathly allergic to anything w/shrimp, so the Thai Kitchen stuff would kill him) and I don’t have words to describe how delicious it is.
I did roast the cauliflower for almost an hour, because my sheet tray was overcrowded (so it was steaming, not browning). I’ll make this over and over, it was one of the best things I’ve made and enjoyed, ever. Thank you!
So thrilled to hear this! Thanks for the feedback!!
I add shallots for deeper flavor and more onions. This makes a ‘thicker’ soup and I don’t need to add the Coconut milk. This saves a lot of calories and helps my weight goals!
Hi! Thanks for the really tasty recipe!)
So happy to hear you enjoyed it! Thank you for taking the time to leave a recipe review. Means a lot! Stay safe and well.
Just made this today in my Vitamix and LOVED it! This soup had a wonderful depth of flavor. Only change was I used low-fat coconut milk, and 2 cups of chicken broth. Thank you for the tips regarding lime juice in soup
Yay! So thrilled to hear that and so glad you could make it your own with the ingredients that best suited you!
Can’t wait to make this!
Can you also share the nutritional content if you have it? I’m trying to figure about how many calories per serving it is…
My non-cauliflower liking husband even loved this soup! I used Sriracha instead of the Thai Chili Paste, because I forgot to look for it at the store. Wonderful and I will make it again!
So happy to hear that!
The best soup I’ve ever made, thank you!! My husband LOVES it.
So thrilled to hear that! Thanks so much for leaving your feedback!
This soup has been one of our favourites to prepare for ourselves and friends. But I think the type of chili paste is key and would like to know what you used? The first time I made it was the best and I used a red chili paste we’d bought at an olive oil farm near Paso Robles where they grew the chilies and made it themselves. The next time I made the soup I bought a red chili paste from Whole Foods (organic Aji Panka — Peruvian) but it was much darker and made the soup taste totally different — not nearly as good.
What brand paste do you use?
I use Thai Kitchen, because it is so readily accessible and I have a feeling its what most people have access to if they’re trying the recipe – but your versions sound great. I definitely want to check out that Aji Panka brand.
I was so looking forward to this soup and I think this recipe totally missed the mark. I’m a fairly sophisticated chef – found that the coconut overwhelmed the cauliflower. Sad I just spent the time and have such a lackluster soup.
This recipe is so delicious. Thank you!!
Made this recipe today, but cut it exactly in half. I had to use siracha in replace of Thai red chili paste and veg broth instead of chicken but it still turned uut amazing!!! ???????????????????? Thanks for the recipe!
Yay! So happy to hear this! Thanks for taking the time to leave a comment/review. Glad to hear all of the substitution worked too.
Thank you so much for the recipe! I misread the ingredinets and added 1 tsp of Thai red curry paste (instead of chili paste) and it turned out fantastic! I will definitely make again with my unintended modification.
Excellent recipe as is. I don’t have a vitamix or immersion blender but who cares. Loved the flavor! Sharing with my vegan friends. De-lish!
Very happy to hear that! Thank you for taking the time to leave a review!
This soup is absolutely delicious!
Yay! So happy to hear that.
I made this soup tonight. 2 thumbs down. It’s got a very grainy consistency and there is way too much Thai chili paste. The heat from the chili paste is overwhelming and you can’t taste anything else.
Sigh. It’s going down the drain tomorrow. Back on the hunt for a good cauliflower soup recipe.
Really sorry to hear that, Pat! I’ve had many readers comment (even just the other day) with positive feedback. Is it possible you didn’t allow the vegetables to cool sufficiently before blending? I can’t imagine how it could have turned out grainy, especially if you used a blender. It is also a relatively small quantity of chili paste, but everyone has varying tolerances for spice – so I apologize if it wasn’t suited for your taste!
Sorry you screwed up the soup Pat. Give it another try, if you get it right it is amazing!
Okay! I just made this today and OMG… TOOO DIE FOR!!!!! I was desperately trying to copy the soup served at Cafe Mogador in NYC (East Village)… which i found oRgAsMiC !!! So, the closest thing aesthetic wise… was Laura’s recipe right here! Truth be told… I’m a sucker for COLOR too… I bookmarked all cali curry soup recipes that were orange yellow in color. Many were an unappetizing beige!! So yah… I was worried that the roast veg didn’t have enough color spice but alas. TOTAL perfection. I confess, I switched it up a bit. I roasted not only the cauliflower, but most the carrots and celery too…. I’m a fiend for roast veggies. I used one of those blender wands (quesinart quick prep hand blenders) to mix it. SOOO EASY!!!! Next time I’ll be doubling the recipe. I want to share it with everyone!!! Nothing says love like an out of this world awesome bowl of soup <3 <3 <3
SMELLS SO GOOD!
can i substitute with bone broth?
I don’t see why not! Bone broth will have a deeper flavor (and generally is thicker), but it should work fine. If in doubt, you could always dilute it slightly (3 cups bone broth and 1 cup water). Hope this helps!
Made your soup for dinner on a cold snowy night and it was delicious and comforting. What’s so special about it too is the healthiness of all the great ingredients.: ginger, turmeric, cauliflower. Gave it a big shoutout on my blog today. http://afterorangecounty.com/2017/01/15/sundays-with-celia-vol-26/
Thanks very much for the terrific recipe!
Thank you so much Celia! I just read your blog post, and appreciate the kind words and feedback more than I can say. So happy to hear that you enjoyed the soup! Hope you’re having a great weekend.
Thank you so much for the kind words Celia!! I’m so thrilled that you enjoyed the soup and thanks for the kind shoutout on your blog – I tried to leave a comment, but was having trouble with Disqus 🙂
You are most welcome Laura. So sorry you had trouble with Disqus. I’ll have to look into that.

Very good soup. I made it vegetarian by using veggie broth instead of chicken, and liked it very much. It was thick and warming and hearty. Next time, I will make a crunchy garnish, maybe croutons, to make it even more to my liking. Thanks!

Laura, how beautiful is this! And it sounds so perfectly cozy for the fall, too. Thank you so much for being a part of this — little B3 feels so loved!
This soup look amazing! Could light coconut milk be used?
Definitely! I prefer full-fat because it is adds a thickness and creaminess that doesn’t compare to light, but it would definitely work.
This soup looks amazing. I love roasted vegetable soups. This is definitely being added to my menu. 🙂
I am so incredibly excited about soup season and about this totally vibrant soup! The color alone gets me all tingly inside.

I just wanna say that this is such a WONDERFULLY TOUCHING & HEART-WARMING creative idea & gesture ! This is going to make the parents of ‘B3’ so HAPPY ! It’s stuff like this that encourages me to continue blogging (even though I often feel like saying, “yeah, that’s enough, time to stop …”). Yet I soldier on. And yeah, oh how I wish-wish-wished I could have been part of this magical sharing moment too !!! Great job, take care & nice meeting you … georgie @ http://www.icookstuff.com 🙂
The colour of this soup – incredible! For soup making, I pretty much roast any and all the vegetables until they are barely discernible, pour in stock and immersion-blend away. I agree, roasting adds so much flavour!
This sounds delicious, and it’s such a beautiful color. I also love making soup, but I also really enjoy eating soup. I’ve not roasted cauliflower for soup yet, so I’m absolutely going to have to give this a try.
that turmeric roasted cauliflower is gorgeous 🙂 comfort in a bowl!
thanks so much for participating laura! i know you brought a smile to cynthia’s face!
Pass me that entire bowl! Love all the flavors happening in this soup, especially with the coconut milk.
I love making baked goods, but soups are a close second for me! I love eating things out of bowls and adore when it’s finally soup weather! Congrats to Cynthia on baby bowl! (Also, thanks for being my Insta-message Cubs friend!) GO CUBS GO! xo
Soup is one of my favourite things to make! And this recipe sounds incredible! Love the roasted cauliflower in there!
I get this question a lot, too, and never know how to answer! I recently decided pesto is my favorite thing to make… But I don’t actually have a whole category I don’t think. Soup is perfect since there’s an endless variety and one that can suit every kind of mood 🙂
