Description

This creamy Roasted Cauliflower Soup combines the rich flavors of oven-roasted cauliflower with aromatic spices and a smooth, velvety texture. Perfect as a comforting starter or a light meal, this soup is easy to prepare and can be made vegan-friendly using coconut milk.


Ingredients

Scale

Vegetables

  • 1 large head of cauliflower, chopped into florets
  • 1 medium onion, chopped
  • 2 cloves garlic, minced

Pantry Items

  • 3 tablespoons olive oil
  • Salt, to taste
  • Black pepper, to taste
  • 1 teaspoon ground cumin
  • 4 cups vegetable broth

Dairy/Alternatives

  • 1 cup coconut milk (or heavy cream for a non-vegan option)

Other

  • Juice of 1 lemon
  • Fresh parsley or chives, for garnish


Instructions

  1. Preheat Oven: Preheat your oven to 425°F (220°C) to prepare for roasting the cauliflower.
  2. Toss Cauliflower: In a large bowl, toss the cauliflower florets with 2 tablespoons of olive oil, salt, and black pepper until well coated for even roasting.
  3. Roast Cauliflower: Spread the cauliflower evenly on a baking sheet and roast for 25-30 minutes, tossing halfway through, until golden brown and tender.
  4. Sauté Onion: While the cauliflower roasts, heat the remaining 1 tablespoon of olive oil in a large pot over medium heat and sauté the chopped onion for 5-7 minutes until translucent.
  5. Add Garlic and Spices: Stir in the minced garlic and ground cumin, cooking for 1-2 minutes until fragrant to build flavor.
  6. Combine Ingredients: Add the roasted cauliflower to the pot with the onions and garlic, then pour in the vegetable broth and stir to combine.
  7. Simmer Soup: Bring the mixture to a boil, then reduce heat and simmer for 10-15 minutes to meld the flavors together.
  8. Blend Soup: Use an immersion blender to puree the soup until smooth, or transfer to a blender in batches, then return to the pot.
  9. Add Creaminess and Finish: Stir in the coconut milk (or heavy cream) and lemon juice, seasoning with additional salt and pepper to taste.
  10. Serve: Serve the soup hot, garnished with fresh parsley or chives for a bright finish.

Notes

  • For a richer soup, substitute coconut milk with heavy cream if dairy is preferred.
  • To make it spicier, add a pinch of cayenne or smoked paprika during the sauté phase.
  • Leftovers keep well in the refrigerator for up to 3 days and freeze nicely.
  • Use an immersion blender carefully to avoid splashing hot soup.
  • For extra texture, reserve some roasted cauliflower florets to add as garnish.
