Method

1. Make the Steak Seasoning

   Combine sea salt crystals, onion granules, garlic granules, smoked paprika, celery seeds, and cracked black pepper in a pestle and mortar. Grind until evenly mixed and aromatic.

2. Prepare the Garlic Roasted Potatoes

   Rinse the potato chunks under cold water. Bring a large saucepan of water to the boil. Add bicarbonate of soda, a generous pinch of salt, garlic, and rosemary or thyme. Add the potatoes and boil for 10–12 minutes, until the edges just begin to soften. Preheat the oven to 220C/200C Fan/Gas 7. Heat your chosen fat in a roasting tray in the oven for 5 minutes until shimmering. Drain potatoes and let them steam-dry in a colander for 2 minutes. Roughen the edges by gently shaking the colander. Carefully transfer potatoes, herbs, and garlic to the hot tray. Toss to coat and roast for 35–45 minutes, turning once or twice, until crisp and golden. Season with sea salt and serve hot.

3. Cook the Sirloin Steaks

   Pat the steaks dry. Rub with vegetable oil and 1 tsp steak seasoning. Heat a grill pan or heavy-based pan over high heat. Grill steaks for 4–5 minutes per side for medium-rare, or 5–6 minutes for medium. Rest the steaks for the same time as cooked. Optionally, flash in a hot oven for 1–2 minutes before slicing and serving. Top with butter if desired.

4. Prepare the Shaved Asparagus Salad

   Shave asparagus into ribbons with a mandolin or sharp knife. Plunge into iced water for 1 minute, then drain and dry. Toss with lemon juice, olive oil, sea salt, and black pepper in a mixing bowl.

5. Mix the Green Herb Sauce

   In a mixing bowl, combine parsley, olive oil, red onion, garlic, oregano, chilli flakes, and red wine vinegar. Season with salt and pepper. Stir until well blended.

6. Serve

   Plate the sliced sirloin steaks alongside the garlic roasted potatoes. Add a generous handful of shaved asparagus salad and spoon over the green herb sauce. Garnish with lemon zest using a zester and scatter fresh herbs if desired.

Additional Notes

For extra flavour, use a blend of rosemary and thyme with the potatoes. Resting the steak is crucial for juiciness-do not skip this step.
