Whole potatoes sliced thinly almost to the base, basted with garlic and thyme butter and roasted until the slices fan open with crisp edges.

Method

  1. 1

    Heat the oven to 200°C.

  2. 2

    Melt the butter with the oil, garlic and thyme leaves in a small saucepan, then take it off the heat.

  3. 3

    Peel the potatoes or simply scrub them well, and trim a thin slice off the base of any that will not sit flat.

  4. 4

    Lay a potato between two chopsticks so they stop the knife, and cut across it at 3 mm intervals down to the sticks.

  5. 5

    Repeat with the remaining potatoes, then rinse them under cold water to wash out starch between the slices and pat dry.

  6. 6

    Set them cut side up on a roasting tray, brush with half the garlic butter and season with salt and pepper.

  7. 7

    Roast until the slices start to open and the outsides are turning golden.

  8. 8

    Brush again with the remaining butter, nudging it down between the slices.

  9. 9

    Roast until deep golden, crisp at the edges and completely tender at the base when pierced with a skewer.

  10. 10

    Sprinkle with a little more flaky salt and serve hot.

Notes

  • The chopsticks are the trick. They stop the knife just short of the base so the potato stays in one piece.
  • Oval potatoes of a similar size give the neatest fans and cook evenly.
  • For a cheesy finish, scatter grated parmesan or Gruyère over the potatoes for the last 10 minutes.
