Ingredients Method Notes

Ingredients
  

  • 3 tablespoons butter
  • 2 tablespoons olive oil
  • 3 leeks cut into 1-inch pieces
  • 1 large head cauliflower chopped
  • 3 cloves garlic finely chopped
  • 8 cups vegetable broth
  • Salt to taste
  • Ground black pepper to taste
  • 1 cup heavy cream optional

Method
 

Heat the Pot:
  1. In a large pot, heat butter and olive oil over medium heat to create a rich, flavorful base.
Sauté Vegetables:
  1. Add leeks, cauliflower, and garlic. Sauté for about 10 minutes, stirring occasionally, until the leeks are tender and fragrant.
Add Broth and Simmer:
  1. Pour in the vegetable broth and bring to a boil. Reduce the heat, cover, and let simmer for 45 minutes until the vegetables are soft.
Blend the Soup:
  1. Remove the pot from heat and use an immersion blender to puree the soup until smooth. Alternatively, blend in batches using a countertop blender.
Season and Finish:
  1. Season with salt and pepper to taste. Stir in heavy cream if a creamier texture is desired, and blend again briefly.
Serve:
  1. Ladle the soup into bowls, garnish with fresh herbs, olive oil drizzle, or your favorite toppings, and serve warm.

Notes

  • Fresh or Frozen Cauliflower: Both work, but fresh provides the best texture and flavor.
  • Make It Vegan: Replace butter with additional olive oil and heavy cream with coconut milk or cashew cream.
  • Texture Control: Blend partially for a chunky texture or fully for a smooth, creamy soup.
  • Spice It Up: Add a pinch of cayenne or red pepper flakes for heat.
