Check out the latest recommended times in our Cooking Guidelines.

Before you start

  • Preheat the oven to 240C / fan 220C / gas mark 9 / air fryer 190C
  • Line a baking tray with parchment paper
  • Pull out a large frying pan & a small bowl

Get the potatoes on

  • Remove the steak from the fridge and allow to come to room temperature. Season both sides with salt and pepper
  • Cut the potatoes into thin wedges. Place onto the lined baking tray and toss with 1 tsp olive oil and a pinch of salt and pepper
  • Roast for 25-30 mins / air fryer 20-25 mins, turning halfway through, until golden

Finish the prep

  • Very finely slice half the shallot, then finely dice the remaining. Finely chop the coriander and parsley. Roughly chop the olives. Halve the tomatoes

Salsa verde time

  • Add the diced shallot to the small bowl, along with the coriander, parsley, olives, red wine vinegar and 1 tsp olive oil. Season with salt and pepper and mix well

Get sizzlin'

  • Heat the large frying pan with 1 tsp olive oil on medium-high heat. Once hot, add the steak and cook (as a guide: cook for 3-4 mins on each side for medium-rare, or 6-7 mins for well done)
  • Quickly seal the edges of the steak, then pour in half the aged balsamic and turn to coat. Remove from the pan and leave to rest

Plate up

  • Thinly slice the steak against the grain
  • Share the steak between plates, with the potato wedges alongside. Drizzle over the salsa verde
  • Serve the rocket on the side, topped with the tomatoes and sliced shallot. Drizzle the remaining balsamic over the salad
