Ingredients

  • 1 (320g) pack ready-rolled puff pastry
  • 1½ tbsp olive oil
  • 25g salted butter
  • 2 rosemary sprigs, leaves picked and roughly chopped
  • 2 leeks, thickly sliced
  • 300g Jerusalem artichokes, thinly sliced
  • 25g blanched hazelnuts, toasted and roughly chopped
  • 6 dollops crème fraîche (optional)
  • 120g rocket

Method

  • Step 1

    Preheat the oven to 200°C/180°C fan/gas 6. Using a large plate that fits on your biggest baking tray as a template, cut out a disc from the pastry. Cover and chill in the fridge.

  • Step 2

    Drizzle 1 tbsp oil onto the baking tray in a circle, roughly the size of the pastry disc. Dot over the butter and scatter with the rosemary and some seasoning. Place the leek and artichoke slices on top in a rough circle, slightly smaller than the disc. Lay the pastry on top and gently press down the edges with a fork.

  • Step 3

    Bake for 35 mins. Remove from the oven, leave to cool for 5 mins, then carefully invert the tart onto a board or plate and scatter over the hazelnuts. Serve slices with a dollop of crème fraîche, if liked, and the rocket dressed with the remaining oil and seasoning. Leftover tart will keep in an airtight container in the fridge for up to 3 days.
