No reviews

Cauliflower Potato and Leek Soup is a creamy, plant-based comfort dish made with just eight simple ingredients. It’s dairy-free, nutrient-packed, and naturally thickened with cauliflower and potatoes—no cream needed.

  • Total Time: 1 hour
  • Yield: 4 bowls

Ingredients

2 tablespoons oil or vegan butter

2 large leeks (white and light green parts only), sliced and rinsed

3 cloves garlic, minced

1 small head cauliflower, cut into florets (about 4 cups)

2 medium Yukon gold or russet potatoes, peeled and diced

4 cups vegetable broth

1 teaspoon fresh or 1/2 teaspoon dried thyme

Salt and pepper to taste

Optional garnishes: chopped chives, shredded vegan cheese, croutons

Instructions

  1. In a large pot, heat oil or vegan butter over medium heat. Add sliced leeks and cook for 5 minutes until softened and lightly golden.
  2. Add garlic, cauliflower florets, diced potatoes, and thyme. Stir and cook for 3 more minutes until fragrant.
  3. Pour in the vegetable broth and bring to a boil. Reduce heat and simmer uncovered for 20 minutes or until vegetables are tender.
  4. Turn off the heat and let cool slightly. Blend the soup using an immersion blender or in batches in a blender until smooth and creamy.
  5. Season with salt and pepper to taste. Return to the pot and warm over medium-low heat if needed.
  6. Serve hot with your favorite toppings such as chives, croutons, or shredded vegan cheese.

Notes

  • Roast the cauliflower first for deeper flavor.
  • Add beans, grains, or nutritional yeast for extra protein or a cheesy twist.
  • Soup can be enjoyed chilled like a vegan Vichyssoise.
  • Make it oil-free by sautéing leeks in broth or water.
  • Frozen cauliflower can be used, no need to thaw first.
