Serves 2


  • Sweet Potato – 240g
  • Celery, very finely sliced – 60g
  • Garlic, finely chopped – 10g
  • Shallot, finely chopped – 10g
  • Shitake mushroom, sliced – 40g
  • Rocket leaves – 50g
  • String bean, whole – 40g
  • Balsamic vinaigrette (see below) – 20 ml
  • Coconut oil – 15ml
  • Pepper black – dash
  • Nutmeg – dash
  • Thyme, chopped – 1 knife tip
  • Balsamic vinegar – 10ml
  • Vegetable stock – 80ml
  • Rice flour – 1tsp
  • Sea salt – dash
  • Garlic, chopped – 2g
  • Shallot, chopped – 3g

Balsamic Vinaigrette Ingredients:

  • Balsamic vinegar – 5ml
  • Olive oil – 20ml
  • Black pepper – dash


  • Cut the sweet potato into very fine stripes (a mandolin will give best results0
  • Heat 10ml of coconut oil in frying pan on low heat. Add the sweet potato, garlic, shallot and celery and sauté for 1 minute. Season with nutmeg and sea salt. 
  • Remove mixture from frying pan, divid into 6 equal parts. Drop each sweet potato portion back in the frying pan, flatten until it is about 1-2cm thick, and sauté on both sides until nice golden brown colour. 
  • Now make the mushroom ragout. Heat the remaining 5ml (1tsp) of the coconut oil in a saucepan and sauté garlic, shallot and shitake for about 5 seconds. Add the balsamic vinegar and cook until reduced. Stir in the vegetable stock, and simmer for 1 minute. Season with a dash black pepper. Take a small bowl or glass and mix the rice flour with a small amount of water (about 1tsp – enough to make a cloudy liquid). Add this to the mushroom mix, stirring continuously until it thickens. Add the thyme and stir through. Remove from heat. 
  • Blanch the beans in boiling water for 1 minute, then plunge into ice water. Remove from water.
  • Make the Balsamic Vinaigrette by whisking (or shaking) all ingredients together. Season the rocket leaves with a dash of sea salt, pepper and the balsamic vinaigrette. 
  • Now to serve. Take your serving plates, and build up a stack – first the roesti, then the beans, then the rocket by 3 times. Spoon the mushroom ragout around the roesti stack.
