Cooking Instructions

The protein cooking time listed in this recipe has been updated.

As of December 2025, we’ve revised cooking times for all our proteins to reflect improved food safety guidance.

Check out the latest recommended times in our Cooking Guidelines.

Before you start

  • Bring a medium saucepan filled with salted water to a boil
  • Full out a large frying pan, a large bowl, a small bowl, a grater & a sieve

Get started

  • Remove the steak from the fridge and allow to come to room temperature. Season both sides with salt and pepper
  • Quarter the potatoes and add to the saucepan. Simmer for 14-16 mins, until softened
  • Meanwhile, thinly slice the spring onions. Finely chop the chives. Trim the broccoli
  • In the final 3 mins, add the broccoli to the potato saucepan, then drain together

Make the salsa verde

  • Finely grate the garlic. Finely chop the parsley. Zest and quarter the lemon. Trim and finely dice the radishes. Deseed and finely dice the chilli
  • In the small bowl, mix together the garlic, parsley, radish, lemon zest, juice from 3 lemon wedges, half the chilli (for those who'd like the heat) 2 tsp olive oil and a pinch of salt

Sizzle the steaks

  • Heat the large frying pan with 1 tbsp 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 sear the edges of the steak, then remove from the pan and leave to rest

Start the salad & finish the potatoes

  • Add the cooked broccoli to the large bowl, along with the remaining chilli (for those who'd like the heat) and half the spring onion. Drizzle with 1 tsp olive oil and toss together
  • Return the cooked potatoes to the pan and crush lightly with the back of a fork. Add the horseradish, chives, juice from the remaining lemon wedge, remaining spring onion and a pinch of salt and pepper. Mix to combine

Plate up

  • Slice the steak against the grain
  • Add the rocket to the broccoli bowl and toss to combine
  • Share the steak between plates, with the crushed potatoes and broccoli salad alongside. Spoon the salsa verde over the steak and salad
