Recipe from The Kitchn
Ingredients (Serves 6 to 8)
2 tablespoons extra-virgin olive oil, plus more to serve
2 medium white onions, thinly sliced
1/2 teaspoon kosher salt, plus more to season
4 cloves garlic, minced
1 large head of cauliflower (about 2 pounds), trimmed and cut into florets
4 1/2 cups low-sodium vegetable broth or water
1/2 teaspoon ground coriander
1/2 teaspoon ground turmeric
1 1/4 teaspoons ground cumin
1 cup coconut milk Freshly ground black pepper, to season
1/4 cup roasted cashew halves, for garnish (optional, see Recipe Note)
1/4 cup finely chopped Italian parsley, for garnish (optional) Red pepper flakes, for garnish (optional)
Heat oil in a large pot over medium heat until shimmering. Cook the onions and 1/4 teaspoon salt until onions are soft and translucent, 8 to 9 minutes. Reduce heat to low, add garlic, and cook for 2 additional minutes. Add cauliflower, broth or water, coriander, turmeric, cumin, and remaining 1/4 teaspoon salt. Bring to a boil over medium-high heat, then reduce the heat to low. Simmer until cauliflower is fork-tender, about 15 minutes.
Working in batches, purée the soup in a blender until smooth and then return the soup to the soup pot. (Alternatively, use an immersion blender to purée the soup right in the pot.) Stir in the coconut milk and warm the soup. Taste and add more salt, pepper, or spices if you’d like.
To serve, ladle the soup into bowls and garnish with a handful of toasted cashews, a few springs of parsley, sprinkle of red pepper flakes, and a dash of olive oil to top.
