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.

  1. Bring a saucepan filled with salted hot water to a boil. Cut the potatoes into 3cm cubes, then add to the pan. Simmer for 15-18 mins, until soft, then drain.
  2. Heat a large frying pan with 1 tbsp oil on medium-high heat. Season the steaks with sea salt and black pepper and cook (as a guide: cook for 2-3 mins per side for medium-rare, or 3-4 mins for medium-well). Remove and leave to rest, then thinly slice against the grain.
  3. Make the tomato sauce; finely dice the shallot. Halve the tomatoes. Reheat the steak pan with 1 tbsp oil on medium heat. Add the shallot, sundried tomato paste, and half the garlic, rosemary and thyme paste. Cook for 2 mins, until softened. Add the tomatoes, cook for 2 mins, then lightly crush with a spoon. Add 250ml hot water then crumble in half the stock cube and stir. Simmer for 3-4 mins, until the sauce thickens.
  4. Bring a saucepan filled with salted hot water to a boil. Trim the green beans, then add to the pan. Boil for 3-5 mins, until cooked. Drain, then season with sea salt and black pepper.
  5. Roughly chop the parsley. Halve the lemon. Return the cooked potatoes to the pan and mash. Stir the parsley through the mash, along with the remaining garlic, rosemary & thyme paste, juice from half the lemon (to taste) and 1 tbsp olive oil. Season with a pinch of sea salt and black pepper.
  6. Pour any steak resting juices into the sauce. Serve the mash on plates alongside the green beans and steak. Spoon over the tomato sauce.
