Equipment

  • Stove

Ingredients

  • 1 head cauliflower large
  • 3 onions medium
  • 3 cloves garlic
  • 2 tablespoons butter
  • 5 tablespoons olive oil
  • 2.5 teaspoons salt
  • ¼ teaspoon black pepper
  • 2 bay leaves
  • 5 cups chicken broth
  • 5 cups water more as required

Instructions

  • Start by peeling and finely dicing the onions
  • To a soup pot, add the butter and half the olive oil and warm up. Add the onions in, season with half the salt, and cook on medium heat for 10-15 minutes until golden brown. Stir every few minutes to avoid burning.
  • Meanwhile, wash and chop the cauliflower into small sized florets
  • Once onions are deeply golden, add the crushed garlic and stir for a few minutes
  • Add in the cauliflower, the rest of the salt, and the rest of the olive oil. Cook for another 10-15 minutes until the cauliflower develops colour. Stir every few minutes
  • Add the black pepper, the bay leaves, the chicken broth and half the water
  • Bring the pot to a rolling boil, half cover the pot and allow it to cook for 30 minutes, reducing to a simmer halfway through
  • Monitor the level of water an add more as required
  • Blend until smooth using an immersion blender (or a stand blender). Taste for seasoning and adjust the salt. Serve with fried cauliflower as garnish, a squeeze of lemon juice and a drizzle of olive oil

Notes

  • Make sure the onions cook down into a golden colour. This process requires a bit of patience and will give you ultimate flavour pay off!
  • You can add in a bit of cream at the end after blending the soup if you like, to give it extra creaminess. It's totally fine without it though
  • Try not to skip the chicken stock - this will give it added flavour (as opposed to using just water)
