Instructions

1

Preheat your oven to 200°C. Remove the steaks from your fridge to allow them to come up to room temperature. Remove the butter from your fridge and leave to one side to soften. Chop the potatoes lengthways into 1cm slices, then chop into 1cm wide chips (no need to peel). Pop the chips onto a large baking tray. Drizzle with oil, sprinkle over the peri peri seasoning, season with salt and pepper then toss to coat. Spread out in a single layer. TIP: Use two baking trays if necessary. When the oven is hot, roast on the top shelf until golden, 25-30 mins. Turn halfway through.

2

Meanwhile, pick the mint leaves from their stalks and roughly chop (discard the stalks). Pick the thyme leaves from their stalks and roughly chop (see ingredients for amount, discard the stalks). Peel and grate the garlic (or use a garlic press).

3

Once the butter has softened slightly, pop into a small bowl and add the garlic and thyme. Use a fork to mash it all together. Season with salt and a pepper then keep to one side.

4

Once the chips have been in the oven for about 15 mins, heat a drizzle of oil in a large frying pan on high heat. Season the steaks with salt and pepper. When the oil is hot, lay the steaks into the pan and fry until browned, 1 min on each side. Lower the heat slightly and cook for another 1-2 mins on each side if you want them medium-rare. TIP: Cook for 1-2 mins more if you like it more cooked. IMPORTANT: Wash your hands and equipment after handling raw meat. The steak is safe to eat when the outside is browned.

5

Once the steaks are cooked, transfer them to a plate, cover with foil. Spread the garlic and herb butter over them, allow them to rest and the butter to melt. Meanwhile, wipe out the frying pan and pop it back on medium-high heat with a drizzle of oil. When the pan is hot, add the peas and chilli flakes (use less if you don't like too much heat). Stir-fry for 2-3 mins. Remove from the heat, season with salt and pepper and stir through the mint.

6

When everything is ready, transfer the steaks to your plates. Drizzle over any buttery juices. Serve with the peri peri chips and peas alongside. Enjoy!.
