Ingredients

Units Scale
  • 4 cups cauliflower (45.9 oz / about 1 large cauliflower) (cut into florets )
  • olive oil
  • 1 yellow onion (chopped)
  • 2-3 coves garlic (sliced or minced)
  • 2 large potatoes (opt for starchy potatoes like Russet or Yukon Gold for a creamier consistency. Peel and cut potatoes into evenly sized pieces to ensure uniform cooking. )
  • 1 large leek (or two small leeks) (remove the leaves and only use the white/green stem.)
  • 4 cups vegetable broth (low sodium)
  • 2 tablespoons fresh parsley or 1 teaspoon Italian seasoning
  • salt and pepper to taste
  • 1/2 cup cream or Greek yogurt ((optional))

Instructions

  1. Roast the Cauliflower: Preheat your oven to 400°F (200°C). Place the cauliflower florets on a baking sheet, drizzle with olive oil, and season with salt and pepper. Roast in the oven for 25-30 minutes or until the cauliflower is golden brown and tender. Set aside.
  2. Prepare the Potatoes and Leeks: In a large pot, heat olive oil over medium heat. Add the chopped onions and a pinch of salt and pepper. Sauté until translucent. Add the minced garlic and sliced leeks, cooking until the leeks are softened.
  3. Cook the Potatoes: Add the diced potatoes to the pot, stirring them into the leek mixture. Allow them to cook for a few minutes to absorb the flavors of the leeks and onions.
  4. Add the Vegetable Broth: Pour in the vegetable broth, ensuring that it covers the potatoes and leeks. Add the herbs. Bring the mixture to a gentle boil, then reduce the heat and simmer until the potatoes are tender.
  5. Blend the Soup: Add the roasted cauliflower to the pot once the potatoes are fully cooked. Using an immersion blender or transferring the mixture to a blender in batches, blend until smooth and creamy.
  6. Finish with Cream (optional): Stir in the heavy cream, allowing the soup to simmer for an additional 5 minutes. This step adds a luxurious creaminess to the soup.
  7. Season and Serve: Season the soup with salt and pepper to taste. Ladle it into bowls, and garnish with fresh chives for a burst of color and additional flavor.

Notes

Serve with a Drizzle or Crunch:

  • Elevate the presentation by drizzling each serving with a touch of olive oil, a swirl of cream, or a sprinkle of cheddar cheese or parmesan.  
  • Add a crunchy element with croutons or a sprinkle of toasted nuts for a delightful texture contrast.

 

Season Mindfully:

  • Season the soup gradually and taste as you go to avoid over-salting. The roasted cauliflower adds a natural nutty flavor that should shine through.
  • Freshly ground black pepper adds a nice touch just before serving.
