What you will need

This recipe uses 6 simple ingredients that you can find at any grocery store:

  • 1 head cauliflower cut into florets
  • 3 cups low sodium vegetable broth
  • 2 tsp ground turmeric
  • 0.5 tsp black pepper
  • 1 whole yellow onion diced
  • 2 tbsp extra virgin olive oil

Step by step instructions

Step 1: Roast the Cauliflower

Preheat oven to 425 degrees Fahrenheit. Toss cauliflower florets with one tablespoon olive oil, one teaspoon turmeric, and a pinch of salt. Spread on a baking sheet and roast for 25 minutes until golden and caramelized.

Step 2: Saute the Onion

While cauliflower roasts, heat remaining olive oil in a large pot over medium heat. Add the diced onion and cook for 8 minutes until soft and translucent, stirring occasionally.

Step 3: Combine and Simmer

Add the roasted cauliflower to the pot with the onion. Pour in the vegetable broth and stir in the remaining turmeric and all the black pepper. Bring to a simmer and cook for 10 minutes.

Step 4: Blend and Serve

Use an immersion blender to blend the soup until completely smooth. Alternatively transfer in batches to a stand blender. Taste and adjust seasoning before serving in warm bowls.

Easy substitutions

Missing an ingredient? Here are some swaps that work perfectly:

  • vegetable broth → chicken broth for a non-vegan version with added protein
  • extra virgin olive oil → avocado oil which also has anti-inflammatory properties

Common mistakes to avoid

Watch out for these pitfalls that can affect your results:

  • Skipping the roasting step and boiling the cauliflower instead which results in a watery flavorless soup
  • Forgetting to add black pepper which is essential for activating the curcumin in turmeric by up to 2000 percent
