Description

This cauliflower soup is rich, creamy, and comforting — made with roasted cauliflower and simple ingredients for a velvety texture and deep, savory flavor.


Ingredients

  • 1 large head cauliflower, cut into florets
  • 2 tbsp olive oil or butter (plus more for roasting)
  • 1 onion, chopped
  • 3 garlic cloves, minced
  • 4 cups vegetable broth or chicken broth
  • Salt and pepper to taste
  • 1 tsp fresh or dried thyme or rosemary (optional)
  • Optional toppings: roasted cauliflower florets, croutons, drizzle of olive oil, fresh herbs

Instructions

  1. Preheat the oven to 425°F (220°C). Toss cauliflower florets with olive oil, salt, and pepper. Roast on a baking sheet for 25–30 minutes until golden and tender, stirring halfway through.
  2. In a large pot, heat 2 tbsp olive oil or butter over medium heat. Add chopped onion and cook until soft and translucent, about 5 minutes.
  3. Add minced garlic and cook for another 1–2 minutes until fragrant.
  4. Add the roasted cauliflower to the pot along with broth, herbs (if using), salt, and pepper.
  5. Bring to a simmer and cook for 10–15 minutes to let flavors blend.
  6. Use an immersion blender or transfer soup in batches to a blender. Blend until smooth and creamy.
  7. Taste and adjust seasoning as needed. Serve hot with your favorite toppings.

Notes

Use olive oil for a dairy-free and vegan version.Roasting the cauliflower adds depth and caramelized flavor to the soup.Add potatoes or carrots for a heartier version.Soup can be frozen for up to 2 months — reheat gently on the stove.Top with croutons, roasted cauliflower, or a swirl of olive oil for added texture and flavor.
