Description

A creamy and comforting roasted cauliflower and leek soup made with cashews for dairy-free richness and miso for umami depth. Simple, wholesome, and perfect for cozy meals on cool days.


Ingredients

    • 2 cups cauliflower, chopped
    • 23 leeks (white and light green parts only), chopped (about 1 to cups)
    • 2 garlic cloves
    • Extra-virgin olive oil, for drizzling
    • ½ cup raw cashews, soaked overnight
    • 1½ teaspoons miso paste (or sea salt)
    • Leaves from a few sprigs of marjoram or thyme
    • 3 cups water (or vegetable broth)
    • 2 tablespoons olive oil (to blend)
    • ⅛ teaspoon smoked paprika (or more to taste)
    • Squeeze of lemon juice
    • Sea salt and freshly ground black pepper, to taste
    • Red pepper flakes, optional
    • Splash of white wine vinegar or champagne vinegar, optional

Instructions

  1. Preheat oven to 400°F (200°C). Spread cauliflower, leeks, and garlic on a baking sheet. Drizzle with olive oil, season with salt and pepper, and roast for 20–30 minutes, turning halfway, until golden and tender.
  2. Transfer roasted vegetables to a blender with soaked cashews, miso paste, marjoram leaves, lemon juice, and 1½ cups of water. Blend until smooth.
  3. Add remaining water, 2 tablespoons olive oil, and smoked paprika. Blend again until creamy.
  4. Pour soup into a saucepan and gently warm. Adjust thickness with more water if needed.
  5. Serve hot with crusty bread, garnished with red pepper flakes or a drizzle of olive oil if desired.

Notes

  • For a nut-free version, replace cashews with white beans or coconut milk.
  • Add roasted carrots or poblano peppers for extra flavor.
  • Spice it up with curry powder or turmeric.
  • Use vegetable broth instead of water for richer taste.
  • Top with truffle oil or toasted pine nuts for a gourmet touch.
