Before you start

A food processor will be very useful to grind the cashews. Cashews need to be soaked 8 h, to form a creamy paste.


  1. Preheat the oven to 205°C/400°F. Prepare the vegetables: Slice the onion into thin rounds; mince the garlic; peel the potatoes then cut them into thin slices, about 0,5 cm.
  2. Heat the oil in a pan over medium heat, then sauté the onion and garlic for about 7 min, until softened and fragrant. Stir in the cinnamon, season with salt and pepper to taste. Remove from heat and set aside.
  3. In a food processor, blend the cashews, nutritional yeast and a few tablespoons of the coconut milk. Blend until smooth and creamy, about 3 min.
  4. Layer the ingredients in an oven proof dish in the following order: Sweet potatoes, onion mixture, cashew cream. Repeat until the gratin has been assembled. In a bowl, mix the remaining coconut milk with the soy milk and oregano, then pour over the gratin.
  5. Cook in the middle of the oven until it is golden-coloured, about 30-35 min. For a nice crust, turn on the top broiler for the last 2 minutes.
  6. Let the gratin stand 10 min before cutting and serving it.
