  • 400g beef fillet, trimmed to an even thickness, at room temperature
  • 1 tbsp vegetable oil, plus extra or deep-frying
  • 25g butter
  • 2 sprigs thyme
  • 1 clove garlic, bashed
  • 300g frozen oven chips, (see notes below)
  • (optional) truffle salt
  • blanched and buttered green beans or mangetout, to serve


  • 10g dried porcini mushrooms
  • 25g butter
  • 1 shallots, finely diced
  • 2 sprigs thyme, leaves picked
  • 200ml port
  • 100ml good-quality beef stock


  • STEP 1

    To make the sauce, pour 100ml of boiling water over the porcini mushrooms and leave to soak for 10 minutes. Heat a pan with the butter and add the shallot, thyme leaves and a pinch of salt. Cook gently for 5 minutes or until the shallot is very soft. Pour in the port, turn up the heat and boil until reduced by 1/2. Pour in the beef stock, add the porcini mushrooms and 50ml of the soaking water and reduce everything by 1/2 again.

  • STEP 2

    Heat the oven to 200C/fan 180C/gas 6. Lightly oil the fillet and season generously. Heat a frying pan to high and brown the fillet for 2 minutes per side on all 4 sides. Add the butter, thyme sprigs and garlic to the pan, melt, and baste the fillet. Put the fillet, thyme, garlic and a little of the browned butter into a roasting tin and roast for 8-10 minutes or until a digital probe thermometer reads 55C. Rest for 5 minutes on a plate. Pour any resting juices from the plate into the sauce.

  • STEP 3

    Heat a pan no more than 1/3 full with vegetable oil to 180C or until a cube of bread browns in 30 seconds. Fry the chips, straight from frozen, for 5-6 minutes until golden brown. Tip onto kitchen paper and season generously with truffle salt, if you like.

  • STEP 4

    Slice the beef and serve with the sauce, chips and buttered green beans.

You can cook the oven chips as usual in the oven but frying them makes them extra crisp.
