  • 2 kg potatoes
  • 3 big white onions
  • 500 gr crème fraîche (double cream)
  • Some nutmeg
  • Salt
  • Pepper


  • Pre-heat the oven (230ºC thermostat 8). Slice the onions and spread them in a plate. Peel the potatoes and slice them thinly.
  • Put a first layer of potatoes in the plate. Cover the potatoes with half of the crème fraîche (the potatoes must be fully covered, if needed add some single cream).
  • Repeat step 2. Be careful to leave a little space on top of the plate to avoid the mixture to boil over.
  • Season with salt, peper and nutmeg.
  • Reduce the heat of the oven to 210ºC thermostat 7 before putting the plate in for 90min. If the top starts to burn, cover it with aluminium foil.
