Cauliflower Purée Soup

My dinner guests really like this unusual soup. Who makes a soup from cauliflower that doesn't taste like cauliflower?

A silky, neutral cauliflower soup that works as a standalone dish or as a versatile base for pot pies, casseroles, and mash-style variations.

Ingredients

  • 1 batch Cauliflower Purée (see linked recipe)
  • 2 cups chicken stock
  • 2 tablespoons butter
  • 1/4 cup sour cream or cream, for added silkiness
  • Salt, to taste
  • Black pepper, to taste
  • Small pinch of nutmeg, for warmth and depth

Method

  1. Prepare a full batch of Cauliflower Purée according to its recipe, ensuring it is thick and well-reduced.
  2. Transfer the purée to a pot over medium-low heat.
  3. Gradually whisk in chicken stock until the desired soup consistency is reached.
  4. Stir in butter and sour cream.
  5. Season with salt, black pepper, and a small pinch of nutmeg.
  6. Simmer gently for 3–5 minutes to fully integrate flavors. Do not boil.

This version treats the soup as a direct extension of the purée, focusing only on thinning, enrichment, and final seasoning adjustments.

Storage

  • Refrigeration: Up to 3 days in an airtight container.
  • Freezing: Up to 2 months; freezes extremely well.
  • Reheating: Warm gently on the stove and loosen with stock or cream as needed.
