Description

This creamy and comforting roasted cauliflower soup combines caramelized roasted cauliflower with savory broth and a hint of smoked paprika, finished with a splash of cream for richness. It’s a delicious, easy-to-make bowl perfect for chilly days or anytime you want a nutritious, warming meal.


Ingredients

Scale

Roasted Cauliflower

  • 1 large head of cauliflower, cut into florets
  • 2 tablespoons olive oil
  • Salt and black pepper, to taste

Sauté Base

  • 1 medium onion, diced
  • 2 garlic cloves, minced
  • 2 tablespoons olive oil (for sautéing)

Soup Liquids and Seasoning

  • 4 cups vegetable or chicken broth
  • 1 teaspoon thyme
  • 1/2 teaspoon smoked paprika (optional)

Finishing Touches

  • 1/2 cup heavy cream or coconut milk (for dairy-free option)
  • Fresh chives or parsley, chopped, for garnish


Instructions

  1. Roast the Cauliflower: Preheat your oven to 425°F (220°C). Toss cauliflower florets with olive oil, salt, and pepper on a baking sheet. Roast for 20-25 minutes until golden and caramelized, which enhances the flavor and texture of the soup.
  2. Sauté Aromatics: In a large pot, heat olive oil over medium heat. Add the diced onion and sauté for 3-4 minutes until softened and translucent. Add minced garlic and cook for an additional minute to release their flavors.
  3. Simmer the Soup: Add the roasted cauliflower, broth, thyme, and smoked paprika to the pot. Bring the mixture to a boil, then reduce the heat and simmer uncovered for 10 minutes to allow the flavors to meld together.
  4. Blend Until Smooth: Using an immersion blender, blend the soup directly in the pot until smooth and creamy. Alternatively, transfer the soup in batches to a regular blender and puree until silky.
  5. Finish Soup: Stir in the heavy cream or coconut milk, which adds richness and smoothness. Adjust the seasoning with additional salt and pepper if needed. Heat the soup for 2-3 more minutes to warm through.
  6. Serve: Ladle the hot soup into bowls and garnish with freshly chopped chives or parsley for a fresh herbal note. Enjoy immediately.

Notes

  • For a vegan or dairy-free version, swap heavy cream with coconut milk or other plant-based cream.
  • Smoked paprika is optional but adds a subtle smoky depth—feel free to omit if you prefer a more straightforward flavor.
  • Leftover soup can be stored in an airtight container in the refrigerator for up to 3 days and reheated gently on the stovetop or in the microwave.
  • To make the soup spicier, add a pinch of cayenne pepper when sautéing the garlic.
  • If you want a thinner soup, simply add more broth or water when blending.
