Ingredients

Scale
  • 1 large head cauliflower, cut into florets
  • 1 tablespoon olive oil
  • 2 tablespoons unsalted butter
  • 1 medium yellow onion, chopped
  • 2 cloves garlic, minced
  • 4 cups low-sodium vegetable broth
  • 1 medium potato (Yukon Gold or Russet), peeled and diced (for creaminess)
  • 1/2 cup milk (whole or 2%)
  • 1/4 cup grated Parmesan cheese (optional, for flavor depth)
  • 1/2 teaspoon salt, or to taste
  • 1/4 teaspoon black pepper, or to taste
  • Pinch of nutmeg

Instructions

  1. Heat the olive oil and butter in a large pot or Dutch oven over medium heat. Add the chopped onion and cook until softened, about 5 minutes.
  2. Add the minced garlic and cook for 1 minute until fragrant. Do not let the garlic burn.
  3. Add the cauliflower florets, diced potato, vegetable broth, salt, pepper, and nutmeg to the pot. Bring the mixture to a boil, then reduce the heat to low, cover, and simmer for 15 to 20 minutes, or until the cauliflower and potato are very tender.
  4. Remove the pot from the heat. Carefully use an immersion blender to blend the soup directly in the pot until completely smooth and velvety. Alternatively, transfer the soup in batches to a standard blender (vent the lid and cover with a towel to prevent steam buildup) and blend until smooth, then return it to the pot.
  5. Stir in the milk and Parmesan cheese (if using). Heat gently over low heat until warmed through; do not boil after adding the milk.
  6. Taste the soup and adjust salt and pepper as needed. Serve immediately with your favorite garnishes.

Notes

  • For an even richer flavor, roast half of the cauliflower florets at 400°F (200°C) for 20 minutes before adding them to the soup base.
  • To achieve a low-carb version, omit the potato and substitute it with 1/4 cup of raw, unsalted cashews soaked in hot water for 15 minutes before blending.
  • Garnish ideas include crispy bacon bits, fresh chives, toasted croutons, or a drizzle of truffle oil for an elegant touch.
