Ingredients
  

  • 1 large head of cauliflower (about 2 to 2.5 pounds), cut into florets
  • 1 large yellow onion, chopped
  • 4 cloves garlic, peeled (leave whole)
  • 3 tablespoons olive oil, divided
  • 1 teaspoon kosher salt, plus more to taste
  • 1/2 teaspoon freshly ground black pepper
  • 1 teaspoon smoked paprika or sweet paprika (optional, for warmth)
  • 1/2 teaspoon crushed red pepper flakes (optional, for a mild kick)
  • 4 cups low-sodium vegetable broth (or chicken broth)
  • 1 cup water, as needed to adjust consistency
  • 1 tablespoon fresh thyme leaves, chopped
  • 2 tablespoons fresh parsley, chopped
  • 1 tablespoon fresh dill, chopped (optional but lovely)
  • 2 tablespoons lemon juice, plus more to taste
  • 2 to 4 tablespoons heavy cream, half-and-half, or unsweetened plant milk (optional)
  • To serve: extra olive oil, cracked pepper, toasted seeds or nuts, fresh herbs

Method
 

  1. Preheat and prep: Set your oven to 425°F (220°C). Line a large baking sheet with parchment for easier cleanup.
  2. Season the vegetables: Toss the cauliflower florets, chopped onion, and whole garlic cloves with 2 tablespoons of olive oil, salt, pepper, and paprika. Spread in a single layer on the baking sheet.
  3. Roast until golden: Roast for 25 to 35 minutes, stirring once halfway through, until the edges of the cauliflower are deeply browned and the garlic is tender and fragrant.
  4. Warm the broth: While the vegetables roast, heat the broth in a pot over medium-low. Keep it warm to help the soup blend smoothly.
  5. Blend the base: Transfer the roasted vegetables to a blender or the pot (if using an immersion blender). Add warm broth and blend until silky. Start with 4 cups broth and add water as needed to reach your preferred thickness.
  6. Season and simmer: Pour the blended soup into a pot if needed. Stir in thyme, parsley, and dill. Bring to a gentle simmer for 5 minutes to marry the flavors.
  7. Finish with brightness: Stir in lemon juice and the remaining 1 tablespoon olive oil. Taste and adjust salt, pepper, and heat. Add red pepper flakes if you like a little warmth.
  8. Make it creamy (optional): Stir in cream or plant milk for extra richness. Simmer 1 more minute; don’t boil.
  9. Serve and garnish: Ladle into bowls and top with a drizzle of olive oil, fresh herbs, cracked pepper, and something crunchy like toasted almonds, pumpkin seeds, or croutons.
