Main Ingredients

  • 1 large head cauliflower, cut into florets
  • 1 whole garlic bulb, cloves peeled (or 6-8 cloves)
  • 2 tbsp olive oil (plus extra for drizzling)
  • 1 medium onion, chopped
  • 4 cups vegetable or chicken broth
  • 1 tsp salt (adjust to taste)
  • ½ tsp black pepper
  • ½ tsp dried thyme (or fresh rosemary)
  • ½ cup heavy cream, coconut milk, or almond milk (optional)

Garnishes

  • Fresh parsley
  • Roasted cauliflower bits
  • Croutons
  • Grated Parmesan

Instructions
 

Roast the Cauliflower and Garlic

  • Preheat oven to 400°F (200°C).
  • Toss cauliflower florets and garlic cloves with 1 tbsp olive oil, salt, and pepper.
  • Spread on a baking sheet and roast for 25-30 minutes, flipping halfway, until golden and caramelized.

Sauté the Aromatics

  • In a large pot, heat 1 tbsp olive oil over medium heat.
  • Add chopped onion and sauté until soft (about 5 minutes).
  • Stir in thyme or rosemary for extra fragrance.

Blend Until Smooth

  • Add the roasted cauliflower and garlic to the pot, followed by broth.
  • Simmer for 10 minutes, then blend with an immersion blender or transfer to a countertop blender in batches.
  • For extra creaminess, stir in heavy cream or coconut milk (optional).

Adjust Seasoning & Serve

  • Taste and add more salt or pepper if needed.
  • Ladle into bowls and top with fresh herbs, a drizzle of olive oil, or crispy roasted cauliflower bits.

Notes

Roast until deeply golden to maximize flavor. Use a high-powered blender for the smoothest texture. Adding a splash of lemon juice brightens the flavors. This soup actually tastes better the next day.
