Make this comforting, rich, and velvety cauliflower soup. It is simple enough for a weeknight meal but elegant enough for company, delivering deep flavor without heavy cream.

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
  • 1/2 cup milk or unsweetened almond milk (for dairy-free option)
  • 1/2 teaspoon salt, or to taste
  • 1/4 teaspoon black pepper, or to taste
  • Pinch of nutmeg
  • 1/4 cup grated Parmesan cheese (optional, for richness)

Instructions

  1. Heat the olive oil and butter in a large pot or Dutch oven over medium heat.
  2. Add the chopped onion and cook until soft and translucent, about 5 minutes.
  3. Add the minced garlic and cook for 1 minute until fragrant. Do not let the garlic burn.
  4. Add the cauliflower florets and vegetable broth to the pot. Bring the mixture to a boil, then reduce the heat, cover, and simmer until the cauliflower is very tender, about 15 to 20 minutes.
  5. Remove the pot from the heat. Use an immersion blender to blend the soup until completely smooth and velvety. Alternatively, carefully transfer the soup in batches to a standard blender and blend until smooth, returning it to the pot.
  6. Stir in the milk (or almond milk), salt, pepper, and nutmeg. If using, stir in the Parmesan cheese until melted and incorporated.
  7. Heat the soup gently over low heat until warmed through. Do not boil after adding milk or cheese.
  8. Taste and adjust seasoning as needed before serving.

Notes

  • For a deeper flavor, roast the cauliflower florets at 400°F (200°C) for 20 minutes before adding them to the pot with the broth.
  • Serve this creamy cauliflower soup topped with fresh chives, croutons, or a drizzle of truffle oil for an elegant presentation.
  • This recipe makes a great low-carb cauliflower soup base; skip the optional cheese for a lighter meal.
