Ingredients
  

Main Ingredients
  • 1 large head fresh cauliflower chopped into florets (reserve 1 cup for roasting garnish) (approx. 2 lbs / 900g)
  • 2 tbsp golden olive oil (30ml), plus extra for drizzling
  • 2 tbsp unsalted butter (30g)
  • 1 medium yellow onion roughly chopped
  • 3 cloves garlic minced
  • 1 medium Russet potato peeled and diced (about 1 cup / 150g)
  • 4 cups low-sodium vegetable or chicken broth (946ml)
  • 1/2 cup heavy cream (120ml), plus extra for swirling
  • 1 tsp kosher salt (5g), adjust to taste
  • 1/2 tsp coarsely ground black pepper (1g), freshly ground, plus extra for garnish
  • 2 tbsp fresh chives or parsley (5g), finely chopped

Equipment

  • 1 Rimmed Baking Sheet Used for roasting the cauliflower garnish.

Method
 

Making the Creamy Cauliflower Soup
  1. Wash and thoroughly dry your large head of cauliflower. Chop it into small, evenly sized pieces. Take about 1 cup (150g) of the smallest, prettiest florets and set them aside for your golden-brown roasted garnish.
  2. Place your Dutch oven over medium-low heat and melt 2 tbsp (30g) of unsalted butter. Add the roughly chopped yellow onion and minced garlic. Sauté gently for 5-7 minutes until translucent, ensuring they do not turn brown to protect the pale ivory color.
  3. Add the remaining raw cauliflower florets and the diced Russet potato to the pot. Pour in 4 cups (946ml) of broth. Bring to a gentle boil, reduce the heat to low, cover, and let it simmer for 20-25 minutes until the vegetables easily fall apart when pierced with a fork.
  4. Preheat your oven to 400°F (200°C). Toss your reserved 1 cup (150g) of cauliflower florets with 2 tbsp (30ml) of golden olive oil and a pinch of kosher salt. Roast on a rimmed baking sheet for 15-20 minutes until they feature slightly charred edges.
  5. Carefully transfer the simmered vegetables and broth into a high-speed blender, working in batches if necessary. Blend on high for 2-3 full minutes until the mixture is entirely pulverized. Return the pale ivory cauliflower soup base to the pot over low heat.
  6. Stir 1/2 cup (120ml) of heavy cream and 1 tsp (5g) of kosher salt into the warm soup base. Ladle into a rustic ceramic bowl. Top with the charred, roasted florets. Create a delicate swirl of heavy cream, drizzle with golden olive oil, and finish with finely chopped vibrant green fresh herbs and a dusting of coarsely ground black pepper.

Notes

Tip 1. Control the Heat: When sweating your onions and garlic, low and slow is mandatory to prevent caramelization and keep the soup pale ivory.
Tip 2. Dry Your Garnish: Ensure the reserved florets are bone-dry before roasting so they get crispy charred edges instead of steaming.
