  • 50g unsalted butter, plus extra for the dish
  • 1 onion, thinly sliced
  • 2 garlic cloves, chopped
  • 50g plain flour
  • 500ml whole milk
  • 250ml chicken or vegetable stock
  • 1kg Maris Piper potatoes, thinly sliced (use a mandoline for the best results)
  • 75g parmesan, finely grated


  1. Heat the oven to 180C/160C fan/gas 4 and butter a deep 20 x 30cm baking dish. Melt the butter in a pan over a medium heat and cook the onion and garlic with a pinch of salt for 8-10 mins until the onion has softened slightly. Tip in the flour, stir well, then cook for a few minutes more. Mix the milk and stock together, then gradually pour this in, whisking well between additions until everything is incorporated and you have a smooth sauce. Simmer for a few minutes, then season well.

  2. Lay half the sliced potatoes in a single layer in the buttered dish, slightly overlapping them if needed. Pour over half the sauce, then scatter over half the parmesan. Arrange the remaining potatoes on top, then pour over the remaining sauce and scatter with the remaining parmesan. Cover with foil and bake for 1 hr, then remove the foil and bake for another 30 mins until golden on top.
