Before you start

  • Preheat the oven to 240C / fan 220C / gas mark 9
  • Line a baking tray with parchment paper
  • Bring a large saucepan filled with salted water to a boil
  • Pull out a medium saucepan, a large frying pan, a medium ovenproof dish, a grater, a peeler & a sieve

Boil the potatoes

  • Cut the potatoes into 1/2cm thick discs (peel optional), then add to the saucepan of boiling water and boil for 10-12 mins, until soft, then drain

Cook the duck

  • Season the duck with salt
  • Heat the large frying pan on medium-high heat. Once hot, add the duck and cook, skin-side down, for 4 mins, until crispy. Flip and cook for 2 mins
  • Transfer to the lined baking tray, skin-side up, and bake for 20 mins until cooked through. Leave to rest

Prep the rest

  • Meanwhile, trim the green beans. Thinly slice the shallot. Remove the woody stalks from the cavolo nero. Finely grate the garlic
  • Heat the medium saucepan with 1 tsp oil on medium heat. Once hot, add the garlic and cook for 30 secs, then stir in the cashew cream. Simmer for 3-4 mins, until thickened. Season generously with salt and pepper

Assemble the dauphinoise & cook the greens

  • Add the cooked potatoes to the cream and stir to coat. Transfer to the medium ovenproof dish and flatten the mixture with the back of a spoon. Bake for 10-12 mins, until golden brown
  • Meanwhile, reheat the frying pan with 2 tsp oil on medium-high heat. Once hot, add the shallot, green beans and cavolo nero. Cook for 3-4 mins, until golden. Season with salt and pepper. Add 2 tbsp water and steam for 2-3 mins, until soft

Make the cranberry sauce & plate up

  • Rinse the potato pan and return to medium heat. Once hot, add the cranberry relish and 1 tbsp water and cook for 1 min, until hot
  • Thinly slice the duck against the grain
  • Sprinkle the truffle zest (or to taste) over the dauphinoise
  • Serve the duck onto plates, with the dauphinoise and greens alongside. Spoon over the cranberry sauce
