Why You’ll Love this Curried Cauliflower Soup

This nourishing soup is brimming with antioxidants and anti-inflammatory ingredients.  

Just like my Tomato and Red Pepper Soup, it’s warm and hearty, yet feels light enough to enjoy on repeat. Plus, it’s vegan, gluten free, and low carb.

The soup is super gingery and aromatic, yet light enough to enjoy alongside something more substantial. Basically the ultimate winter warmer, if you ask me. (Much like this Cauliflower Potato Soup!)

I love serving it alongside a salad or sandwich, or simply as is with some bread or naan. It’s an incredibly satisfying way to sneak in extra veggies once the cooler weather sets in.

Recipe Ingredients

Cauliflower soup ingredients in separate bowls with blue labels.
  • Cauliflower: You need one medium (2-lb.) head of cauliflower sliced into florets. For those looking for lower carb recipes, cauliflower is a fantastic option. It turns this soup just as rich and creamy as if it were made with starchier root vegetables.
  • Aromatics: Yellow onion, fresh garlic, and ginger create the aromatic backbone of this soup. It’s really important to use fresh, whole garlic cloves and ginger root, which pack more flavor. 
  • Green Curry Paste: This flavor-loaded condiment is made out of green chiles, garlic, lemongrass, ginger, and kaffir lime. It’s incredibly aromatic, and packs a major punch. I use Thai Kitchen brand, which you can find in the international aisle of pretty much any grocery store. 
  • Lemongrass Paste: This shortcut ingredient packs all the goodness of fresh lemongrass in a convenient paste. I use this Lemongrass Turmeric Paste, which is available at most grocery stores in the international aisle, or in the produce section.
  • Broth: If making this soup vegan, use vegetable broth. Otherwise, chicken broth also works great!
  • Coconut Milk: For luscious, velvety richness, canned coconut milk is added at the end to give the soup body.
  • Lime Juice: For a pop of brightness and acidity, the juice of one whole lime works wonders. This amounts to roughly 2 Tbsp.
  • Garnish: I love garnishing this cauliflower soup with crispy chickpeas and herbs. The chickpeas are a great way to slip in some protein!

See the recipe card for full information on ingredients and quantities.

Substitutions/Additions

  • Make Lower Fat: If you’re looking for a lower saturated fat alternative to coconut milk, homemade cashew cream also works well.
  • Add Protein: Add half a block of silken tofu to the soup before blending to make it more satiating.
  • Make Vegan: This soup is vegan as written as long as you use vegetable broth.

Step-by-Step Instructions

Step 1: Sauté Aromatics – In a large stock pot or Dutch oven, cook onion until soft, about 8 minutes. Stir in garlic, ginger, curry paste, and lemongrass paste; cook until aromatic.

Step 4: Blend – Carefully transfer cauliflower soup to a blender. (Alternatively, leave soup in pot and use an immersion blender to blend until smooth).

Add coconut milk and remove center piece of blender lid. Secure lid on blender, and place a clean kitchen towel over opening in lid (to avoid splatter). Process the soup until completely smooth, about 1 minute.

Recipe FAQs

What to Serve with Cauliflower Soup:

While this soup is super hearty, you may desire a little something on the side. Ideally something with a good punch of protein. Here are a few of my favorite pairings:

Salad: This Winter Chopped Salad with White Balsamic features white beans and sweet potatoes for a filling and flavorful side. This Thai Butternut Quinoa Salad is also an amazing compliment to the soup’s flavor.

Sandwich: For a non-veg option, this Green Goddess Chicken Salad Sandwich will make for a mighty fine lunch. Or for the vegetarians, I can’t recommend these Crispy Eggplant Sandwiches enough!

Protein: For a plant-based option that’s super satiating, try my Moroccan Lentil Meatballs or Chickpea Meatballs.
Bread: Garlic bread, pita, or naan are perfect for dunking into this soup and sopping up the remains.

How to Store and Reheat:

To Store. Store cooked and cooled soup an airtight storage container in the refrigerator for up to 5 days.

To Reheat. Reheat soup in a pot on the stove over medium heat, stirring often, until warm.
Alternatively, place leftover soup in a microwave-safe bowl and microwave in 1-minute increments, stirring often, until warmed through. If needed, add a splash of broth, water, or milk to thin out.

How to Freeze Cauliflower Soup:

Let soup cool until it’s close to room temperature before transferring to a freezer-safe storage container or ziptop bag.
Lay flat in the freezer for up to 3 months.
Let thaw overnight in the refrigerator before reheating

  • Immersion Blender: it makes pureeing soups like this one easier (and safer) than transferring the piping hot soup mixture to a blender.
  • Blender: I love my Kitchenaid K400 blender, and use it very often. Some say it’s comparable to the Vitamix, just much more affordable.
  • Dutch Oven: I use my Lodge Enameled 6-qt Dutch Oven for every single homemade soup recipe. It’s a staple piece on my stovetop, and has endless functionality. Lodge is also quite a bit cheaper than Cuisinart, yet just as good quality, in my opinion.
  • Ladle: For transferring the soup to the blender (and to your bowl!), you need a reliable ladle.

    This was easy but so flavorful! My husband couldn’t stop eating it 😉 Served with warm naan. I found Mehkala brand organic curry and lemongrass paste at my NY Whole Foods – highly recommend if you can find it! It’s spicier than Thai Kitchen though so you might want to start with a little less. Next time I might cut back on the cauliflower a bit and add some white beans for protein, but the recipe is perfect as is.

    After making this I sent the link to my mom and two best friends. This soup is incredible! Truly silky smooth and no way to guess there’s so much cauliflower in it! A true winner. I couldn’t find lemongrass paste so upped the green curry paste by another half tablespoon. The soup has a real kick but an enjoyable one. Thank you!
