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 200C
  • Line a baking tray with parchment paper
  • Pull out a medium bowl, a grater & a large frying pan

Golden potatoes

  • Remove the steaks from the fridge and allow to come to room temperature. Season both sides with salt and pepper
  • Cut the potatoes into 2cm cubes
  • Place the potatoes onto the lined baking tray, drizzle with 1 tbsp oil and season with salt and pepper
  • Roast for 25-30 mins / air fryer 20-25 mins, until golden

Make the salsa

  • Meanwhile, finely chop the parsley and thinly slice the olives. Thinly slice the spring onions. Quarter the tomatoes. Zest and cut the lemon into wedges
  • Place the parsley, tomatoes, olives and half the spring onion into the medium bowl with 1 tbsp oil. Squeeze in the juice from half the lemon and season with salt and pepper. Mix well and set aside
  • Finely chop or crush the garlic. Rinse the spinach

Get sizzlin'

  • Heat the large frying pan with 1 tbsp oil on medium-high heat. Once hot, add the steaks and cook (as a guide: cook for 3-4 mins on each side for medium-rare, or 6-7 mins for well done). Quickly sear the edges of the steaks, then leave to rest.

Wilt the spinach

  • Return the now-empty steak pan to medium heat with 1 tsp oil. Once hot, add the garlic and cook for 30 secs, then add the spinach and cook for 1-2 mins, until wilted
  • Add a squeeze of lemon juice, season with salt and pepper, and remove from the heat

Plate up

  • When ready, add the lemon zest and remaining spring onion to the potatoes and toss to combine
  • Slice the steaks against the grain, then serve on plates, with the potatoes and garlicky spinach alongside
  • Spoon the tomato olive salsa over the steaks. Garnish with any remaining lemon wedges
