Velvety Roasted Cauliflower Soup: Coconut Turmeric Delight

Creamy Roasted Cauliflower Soup with Coconut & Turmeric: A Healthy, Dairy-Free Delight

One of the most transformative techniques for elevating a soup from simple to spectacular is incorporating roasted vegetables. This process isn’t just a step; it’s a flavor development superpower. When vegetables are roasted, their natural sugars caramelize, deepening their flavor, adding a subtle sweetness, and imparting a rich, nutty complexity that mere boiling or steaming can’t achieve. This creamy roasted cauliflower soup with coconut and turmeric is a prime example of this magical transformation.

Here, humble cauliflower florets are tossed with vibrant ground turmeric and then roasted until they achieve a beautiful golden-brown hue, becoming lightly caramelized and delightfully tender-crisp. Honestly, these turmeric-roasted florets are so delicious, you could serve them as a side dish on their own! Roasting is particularly beneficial for vegetables that might otherwise be considered a bit “bland,” such as cauliflower, broccoli, or various root vegetables. Much like potatoes, cauliflower also boasts the incredible ability to create an exceptionally creamy soup texture when pureed. This means you can achieve that luxurious, velvety mouthfeel without needing to add heavy cream, starch, or any unnecessary richness, making it an ideal base for healthy, dairy-free, and even vegan soups.

This exquisite roasted cauliflower soup recipe is a thoughtful adaptation from the truly inspiring cookbook, Clean Soupsby Rebecca Katz. My mom, a fellow soup enthusiast (who might even love soup more than I do!), recently gifted me this gem, and I’ve been eagerly exploring its pages ever since. The book brilliantly deconstructs soup-making into fundamental building blocks: fat, aromatics, broth, herbs, and spices. Understanding these core components empowers home cooks to move beyond strict recipe adherence and confidently begin crafting their own unique soup creations from scratch. This philosophy resonates deeply with my own approach to cooking, which values intuition and experimentation.

While this blog features quite a few cauliflower recipes, spanning from roasted sides to hearty main dishes, this particular coconut and turmeric infused soup has quickly ascended to become one of my absolute favorites. Its blend of comforting creaminess with exotic, warming spices makes it truly stand out.

Key ingredients for healthy roasted cauliflower soup with turmeric and coconut milk

After nearly seven years immersed in the professional culinary world, one question I frequently encounter is, “What type of food do you most enjoy making?” You’d think with all that experience, the answer would be something grand and complex, right? Unfortunately, the real answer isn’t quite as dramatic or conversation-starting as some might expect. While homemade pizza and fresh pasta certainly rank high on my list, often the immense satisfaction comes simply from the joy of eating them. But when it comes to the process – what I genuinely enjoy making the most? That’s a much harder question, but believe it or not, soup consistently tops my list.

Yes, soup. There’s a deeply meditative quality to the mindless chopping, dicing, and precise prep work that lays the foundation for a truly great bowl of soup. I love the quiet rhythm of the kitchen as ingredients transform. Beyond the comforting warmth and hearty satisfaction it brings to the table, soup is incredibly versatile. It graciously encourages a variety of accompaniments—a crisp, hearty salad, a great crusty loaf of bread for dipping, or a selection of fine cheeses. But the absolute best part? Soup lends itself remarkably well to experimentation in the kitchen. **If you’re feeling a bit uncomfortable improvising or eager to start putting your own unique spin on recipes (rather than strictly following them), I wholeheartedly recommend starting with soup.** It’s a forgiving medium that allows for creativity without high stakes.

Soup’s forgiving nature means it can be flavored, adjusted, and enhanced in countless simple yet impactful ways. For instance, if you can’t consume dairy but still desire a luscious, creamy soup, fear not! You can easily substitute traditional heavy cream with rich, full-fat coconut milk (as we do in this recipe!) or achieve a similar velvety effect with the addition of a starchy root vegetable like a potato or sweet potato. In fact, this blog’s popular roasted acorn squash and sweet potato soup is completely vegan and celebrated for its incredible creaminess.

Eager to infuse a classic soup with an exciting international twist? Simply swap traditional herbs and spices for exotic blends like aromatic garam masala, pungent ground ginger, complex curry powder, or in the case of today’s healthy cauliflower soup, a kick of authentic Thai chili paste. Even seemingly minor additions, such as a touch of freshly grated ginger or a bright squeeze of lemon or lime juice, can dramatically elevate and completely transform a soup’s entire flavor profile, adding layers of complexity and brightness.

For an extra boost of protein and satisfying heft, consider pureeing a can of drained cannellini or garbanzo beans and stirring them into the soup halfway through cooking. This simple trick adds body and nutritional value without altering the flavor too much. Or let the seasons inspire you! Trade a conventional yellow onion for the delicate sweetness of leeks, swap carrots for earthy parsnips, or replace sweet potatoes with your favorite winter squash like butternut or kabocha. The possibilities are endless. But my single most crucial tip for crafting an exceptional bowl of soup?

Never, ever underestimate the profound power of salt and acid. These two elements are fundamental flavor balancers. If your soup creation tastes a little flat, dull, or simply “off,” nine times out of ten, it needs a generous pinch of kosher salt or a vibrant squeeze of lemon or lime. (Personally, I often prefer lime for soup, as its acidity tends to be a bit more delicate and nuanced.) The right balance of salt and acid can truly make or break a soup, bringing all the flavors into perfect harmony.

In my kitchen, soups are incredibly versatile and can grace the table for practically any occasion, from a comforting weeknight meal to a festive celebration. This particular roasted cauliflower soup was made in celebration of Cynthia, the talented creator behind the beautiful food blog Two Red Bowls. Just a few days prior, Cynthia welcomed her incredibly adorable baby boy, Luke, into the world! To honor this joyous news, a wonderful group of internet friends came together to celebrate with – you guessed it – foods made or served in bowls! It’s such a fun and heartwarming way to share in the excitement, reflecting the comforting and communal nature of food.

Between the incredible World Series victory by the Cubs last night, yesterday’s (literal) toast in celebration of Ashley, and today’s delightful “bowl party” in honor of Cynthia, it has been quite an eventful and celebratory week. These moments remind us how food can bring people together, both virtually and in real life, to share joy and comfort. Cheers to good food, good friends, and happy occasions! Have a truly wonderful weekend, friends!

This incredibly healthy roasted cauliflower soup recipe features aromatic turmeric-roasted cauliflower and is infused with fragrant Thai chili paste and rich coconut milk. It’s naturally dairy-free and can be beautifully garnished with fresh cilantro and a few reserved roasted cauliflower pieces for an elegant touch.

Equipment

  • Half Sheet Pan

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, for garnish

Instructions 

  • Preheat your oven to 425°F (218°C). Line a large half sheet pan with parchment paper for easy cleanup. In a spacious mixing bowl, toss the cauliflower florets evenly with 2 tablespoons of extra virgin olive oil, ½ teaspoon of ground turmeric, ½ teaspoon of Diamond Crystal kosher salt, and a generous amount of freshly ground black pepper. Spread the seasoned florets in a single layer on the prepared sheet pan. Roast for 20 to 25 minutes, making sure to flip the florets halfway through, until they are tender, beautifully caramelized, and slightly crispy.
  • While the cauliflower roasts, heat the remaining tablespoon of olive oil in a large, heavy-bottomed soup pot over medium heat. Add the diced yellow onion, the remaining ¼ teaspoon of turmeric, and a small pinch of salt. Sauté, stirring occasionally, for 3 to 4 minutes until the onion is softened and appears slightly translucent. Next, add the minced garlic, diced carrots, and diced celery. Continue to sauté for 10 to 12 minutes, stirring intermittently, until these vegetables are tender and lightly caramelized. Stir in the Thai chili paste, ensuring the vegetables are evenly coated with its aromatic flavors. Pour in ¾ cup (180 mL) of chicken broth, scraping the bottom of the pan thoroughly to loosen any flavorful caramelized bits. Continue to cook until the liquid has reduced by half. Finally, add the remaining chicken broth, grated fresh ginger, and all the roasted cauliflower to the pot. Bring the mixture to a gentle boil, then reduce the heat to low and let the soup simmer for 10 to 15 minutes, or until all the vegetables are very tender.
  • Carefully transfer the hot soup in batches to a high-powered blender, such as a Vitamix. Puree until the soup is completely smooth and creamy. If the soup appears too thick for your preference, add a bit more broth until it reaches your desired consistency. Transfer the pureed soup back to the clean soup pot. Place it over low heat and whisk in the full-fat coconut milk until thoroughly combined and heated through. Stir in the fresh lime juice. Taste and season generously with additional salt and pepper as needed to achieve a balanced and vibrant flavor profile.
  • Serve this delicious Roasted Cauliflower Soup hot. Garnish each bowl with a sprinkle of finely chopped cilantro leaves for a burst of freshness and color.

Tips for Success:

  • Once the soup is pureed and the coconut milk is incorporated, it’s crucial to taste it before serving. If the flavor seems a little “flat” or lacks vibrancy, the soup most likely needs a few good pinches of kosher salt or another squeeze of fresh lime juice to brighten and balance all the ingredients.
