Ingredients

  • 2 tablespoon butter or extra virgin olive oil
  • 1 small yellow onion finely diced (½ cup / 60g)
  • 2 medium carrots peeled and diced (1 cup / 140g)
  • 1 small leek diced (1 cup / 75g)
  • 3 medium stalks celery diced (1 cup / 120g)
  • 1 zucchini diced (1.5 cup / 170g)
  • ½ cup / 50g green beans chopped into 1 cm pieces
  • 3 cups / 300g cauliflower chopped into small florets
  • 1 cup kale chopped, 50g
  • 1 tablespoon thyme leaves chopped
  • 1 tablespoon rosemary chopped
  • 3 tablespoon fresh parsley chopped
  • 3 garlic clove minced
  • 7 cup / 1.7l chicken broth Or vegetable broth if vegetarian. Increase to 2 litres / 8 cup depending on vegetable amount
  • 2 bay leaves
  • ¾ teaspoon salt or to taste dependent on how salty your stock is
  • ½ teaspoon cracked black pepper or to taste

Instructions

  • Heat 2 tablespoon of butter or olive oil in a non stick soup pot and sauté on a medium heat. Add the onion, carrots, leek and celery and fry for about 5 minutes until they start to soften. Add the garlic, zucchini, green beans, chopped thyme and about ⅔ of the parsley. Sauté for another 3 minutes.
  • Add the cauliflower, broth, bay leaves, seasoning and bring to the boil. Reduce to a simmer and cook with a lid on for about 15 minutes.
  • Remove half the mixture and bay leaves (discard the bay) and put into a jug and pulse with stick blender. Option to place in a high speed blender if you prefer. This thickens the soup and adds flavour.
  • Add the pureed soup back into the pan along with the greens and simmer until they soften (about 1 minute).
  • To serve: Mix a squeeze of lemon juice with 1 tablespoon olive oil and swirl into the soup. Top with 1 tablespoon fresh parsley. Adjust seasoning to taste and enjoy.
