Here is a recipe for Creamy Cauliflower Soup (Low Carb)! There’s nothing easier when you want a soup with only a few ingredients and low in carbs. To make this recipe more original, I roasted part of the cauliflower and served it with the soup.

  • 1 cauliflower
  • 1 onion
  • 400 ml vegetable stock
  • 1 lemon
  • Salt and pepper
  • Olive oil


  • Preheat the oven to 180 °C.
  • Cut the cauliflower into florets. Reserve a few halved florets for decoration. Keep the stem of the cauliflower and the thinnest leaves. Chop them roughly.
  • Peel the onion and fry it in a large pan with a drizzle of olive oil. After 2 minutes, add the cauliflower. Sauté for one minute.
  • Pour in the vegetable stock and cook over medium heat for 20 minutes.
  • Cover the florets reserved for decoration with olive oil. Place them on a baking sheet covered with parchment paper. Bake for 15 minutes in the oven. Turn the florets over after 8 minutes.
  • Once the cauliflower is cooked, add a dash of lemon juice. Add salt and pepper. Finally, mix the whole to obtain a velvety consistency.
  • Pour the soup into a bowl and garnish with a few oven-roasted cauliflower florets.


This soup goes very well with smoked salmon.
