step 1
Preheat the oven to 200°C/180°C fan/gas mark 6. Add the dauphinoise potatoes (1 pack) to the oven and bake for 30 minutes, according to packaging instructions.
step 2
Meanwhile, prepare the pea purée. Melt the butter (1 tbsp) in a saucepan, add the frozen peas (300 g) and chicken stock (100 ml), season with salt and pepper, and simmer gently for 5 minutes. Transfer to a blender and blitz until smooth. Set aside and reheat when ready to serve.
step 3
Cook the crispy mushrooms (1 pack) in the air fryer at 200°C for 10 minutes.
step 4
Heat a splash of oil in a large frying pan over a high heat. Rub the steakhouse seasoning (1 tsp) into the steaks (2), then sear the steaks evenly on both sides until a deep golden crust forms, or until the internal temperature reaches 51°C. Reduce the heat, then use tongs to stand them on their sides to render the fat (in other words, melt the fat!). Transfer the steaks to a plate to rest.
step 5
Return the pan to a low heat with a splash of vegetable oil, add the whole spring onions (4) and cook until tender, tossing occasionally. Slice the lettuce (1) into thin wedges and toss in the pan with the spring onions and steak juices. Season with a drizzle of olive oil and sea salt just before serving.
step 6
Divide the steaks between your plates, then serve alongside the creamy dauphinoise potatoes, pea purée, roasted spring onions, shaved gem lettuce and crispy garlic mushrooms.
