For the Soup:

  • 2 tablespoon extra virgin olive oil See Note 1
  • 1 large brown/yellow onion - roughly chopped
  • 3 cloves garlic - peeled and chopped
  • 500 gm (17 ounces) broccoli - divided into florets reserve the stems - See Note 2
  • 2 medium potatoes - peeled and chopped
  • 3 cups (750 ml) vegetable stock
  • 2 teaspoon fresh thyme leaves
  • sea salt and black pepper to taste
  • ¼ cup fresh parsley leaves See Note 3

To Garnish: (optional)

  • fresh parsley leaves
  • finely grated lemon zest


  • Heat the olive oil in a large saucepan over medium heat.
    Saute onion about 5 minutes, stirring occasionally, but do not let it colour.
  • Add garlic, saute about 2 minutes. Be careful it does not burn.
  • Add broccoli, potato, vegetable stock and thyme leaves.
    Season with salt and freshly ground black pepper.
  • Bring the mixture a boil, then reduce the heat, and simmer 15 minutes, or until the vegetables are tender.
    Remove the saucepan from the heat and add the parsley leaves. See Note 3.
  • With a hand mixer, or in a blender, puree the mixture until smooth. See Note 4.
    Reheat in the saucepan, season to taste with salt and pepper. See Note 5.
  • Add a little finely zested lemon rind and some chopped parsley to the top of each of the bowls. See Note 6.


  1. In Australia, the tablespoon is 20 ml or 4 teaspoons. In many other countries, the tablespoon is 15 ml or 3 teaspoons. You may have to adjust your measurements accordingly.
  2. This is the weight of the broccoli once you have removed the stems.
    Reserve the stems to use separately - peel them and cut into steps and use as part of a crudité platter, or add to a salad such as my Broccoli Stem Slaw.
  3. Adding the parsley just before blending adds colour, flavour and nutrients.
  4. If you do use a blender for hot liquids, you must be careful. You will need to remove the central cap in the blender lid and then cover the lid with a folded tea towel to let the steam escape. Hold the lid on securely and blend on a low speed. This will allow steam to escape so that it doesn’t build up. Not doing this can pose a risk that soup may overflow out of the blender.
  5. Adjust the seasoning to your liking - we recommend using freshly ground black pepper and sea salt flakes for the best flavour.
  6. A little finely zested lemon and additional parsley is a delicious flavour booster, and adds a bright tone to the soup.
  7. Please note, the nutritional information is based on the recipe making approximately 6 cups. One cup is equal to 250ml. This does not include the garnish you serve with the recipe. The nutritional information is an estimate only.
