SERVES: 6 PREP TIME: 15 mins COOK TIME: 45 mins


  • 1 cup red lentils
  • 1 cup French Puy lentils
  • 1 litre vegetable stock
  • 1 litre water
  • 1 large sweet potato, peeled and diced into medium cubes
  • 4 cloves garlic, whole
  • ½ teaspoon chilli powder
  • 1 teaspoon turmeric powder
  • 2 heaped tablespoons mild curry powder
  • ½ teaspoon freshly ground black pepper
  • Avocado oil or other light oil for frying
  • 2 medium onions, finely diced
  • Juice of 1 lemon


  1. Wash the lentils together in a sieve until the water runs clear.
  2. In a large pot add the lentils, stock, water, sweet potato, garlic, chilli, turmeric, curry powder and pepper.
  3. Bring the soup to a boil, then turn the heat down as low as it will go and cover with a lid leaving a small gap for steam to escape, and let it simmer gently.
  4. In a frying pan, heat the oil, then add the onions and gently fry until golden brown.
  5. Add the onions to the soup making sure to include any brown bits from the pan (they add lots of flavour to the soup).
  6. Continue to simmer the soup for an approximate total of 45 minutes.
  7. Remove from the heat, add the lemon juice, stir well and serve hot.


  • This soup can be made a day ahead and reheated when ready to serve.
  • A great soup for planning ahead and freezing.
  • Add roughly chopped coriander, parsley leaves or finely chopped fresh red chilli when serving.
  • Mix it up a bit and use lime juice instead of lemon.
  • Sprinkle with Dukkah for some exotic flavour or Harissa for a bit of zing.
