Ingredients
1 tablespoon coriander seeds
2 tablespoons extra-virgin olive oil, more for serving
1 large white onion, peeled and diced (2 cups)
2 large garlic cloves, finely chopped
5 medium carrots (1 pound), peeled and cut into ½-inch pieces (2 cups)
1 ½ teaspoons kosher salt, more as needed
3 tablespoons white miso
1 small (or half of a large) head cauliflower, trimmed and cut into florets
½ teaspoon lemon zest
2 tablespoons lemon juice, more to taste
Smoky chile powder, for serving
Coarse sea salt, for serving
Cilantro leaves, for serving
Preparation
- Step 1
In a large, dry pot over medium heat, toast coriander seeds until fragrant and dark golden-brown, 2 to 3 minutes. Transfer to a mortar and pestle and coarsely crush.
- Step 2
Return the pot to medium heat. Add the oil and heat until warm. Stir in onion; cook, stirring occasionally, until soft and lightly colored, 7 to 10 minutes. Stir in garlic and cook 1 minute.
- Step 3
Add carrots, crushed coriander, salt and 6 cups water to the pot. Stir in the miso until it dissolves. Bring mixture to a simmer and cook, uncovered, 5 minutes. Stir in cauliflower and cook, covered, over medium-low heat until the vegetables are very tender, about 10 minutes.
- Step 4
Remove the soup from the heat. Using an immersion blender, purée the soup until smooth. (Alternatively, you can let soup cool slightly then purée it in batches in a food processor or blender.) If necessary, return the puréed soup to the heat to warm through. Stir in the lemon zest and juice just before serving. Drizzle with oil and sprinkle with chile, sea salt and cilantro leaves.

One question: I toasted the coriander seeds and coarsely crushed them with a mortar and pestle. I followed the recipe in detail. The soup was great but we were spitting out the husks (or hulls) of the coriander. Did I do something wrong? Did others have the same experience?
To the editors: I would like it if instead of saying, "1 small (or half of a large) head cauliflower" you would give the weight of cauliflower needed.
This soup is delightful! I used veg broth instead of water, roasted the cauliflower and carrots rather than cooking in the broth, and added bay leaves and then some scallions at the end. The soup somehow ends up tasting like a bowl of creamy, cheesy cauliflower-cheddar even though there isn't a drop of dairy. Highly recommended!
It was tasty but mine looks nothing like the picture. The picture shows a very thick creamy soup. I followed the recipe exactly.
using purple and yellow carrots made for a rather beige soup, albeit a good one.
Has anyone tried this as a chilled summer soup?
