This creamy cauliflower and leek soup offers a velvety smooth texture with the gentle sweetness of sautéed leeks and the delicate earthiness of cauliflower, blended into a comforting bowl perfect for any season.

  • Total Time: 35 minutes
  • Yield: 4–6 servings

Ingredients

Vegetables

  • 2 leeks, white and light green parts only, sliced
  • 1 head cauliflower, chopped

Liquids & Fats

  • 2 tbsp butter
  • 4 cups vegetable broth
  • 1/2 cup heavy cream

Seasoning

  • Salt, to taste
  • Black pepper, to taste

Instructions

  1. Sauté the leeks: In a large pot, melt the butter over medium heat. Add the sliced leeks and sauté them gently until they are soft and fragrant, which should take about 5-7 minutes. This step develops the base flavor of the soup.
  2. Add cauliflower and broth: Stir in the chopped cauliflower, then pour in the vegetable broth. Bring the mixture to a boil, then reduce the heat and let it simmer gently for about 20 minutes, or until the cauliflower is very tender.
  3. Blend the soup: Using an immersion blender directly in the pot or carefully transferring the mixture to a blender, blend the soup until it becomes smooth and creamy without lumps.
  4. Finish with cream and seasoning: Stir in the half cup of heavy cream for a rich, velvety texture. Season the soup with salt and freshly ground black pepper to your taste. Warm through for a couple more minutes, then serve hot.

Notes

  • For a dairy-free version, substitute the butter with olive oil and the heavy cream with coconut cream or a plant-based alternative.
  • You can garnish with fresh herbs like parsley or chives for added flavor and color.
  • Adjust the consistency by adding more vegetable broth if a thinner soup is preferred.
  • This soup freezes well; cool completely before freezing in airtight containers for up to 2 months.
