Ingredients

  • 4 medium onions, red, white, or 1 of each
  • 4 large potatoes
  • 50 g (¼ cup) butter
  • A few handfuls of grated gruyere cheese, as many as you dare

Instructions 

  • In a covered saucepan, caramelize the onions in half of the butter over a very low heat, for about an hour.
  • Meanwhile, chop and boil the potatoes for about 20 minutes, until soft.
  • Drain the potatoes.
  • Take a few spoonfuls of onion from the pan and set aside for the topping.
  • Use a potato ricer to rice the potatoes into the saucepan with the remaining caramelized onions.
  • Add the rest of the butter and put back onto a very low heat as you stir the potatoes, onions and butter together.
  • Once incorporated, add cheese and keep stirring as it melts through.
  • The final texture should be smooth but sticky, with the potatoes coming away from the pan easily.
  • Top with the reserved onions and serve.
