Cook the Chips

Preheat your oven to 220°C/200°C fan/gas mark 7. Remove the steaks and butter from your fridge to allow them to come up to room temperature.

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.

Prep Time

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). 

Make your Garlic Thyme Butter

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 pepper, then keep to one side.

Fry the Steaks

Once the chips have cooked for about 15 mins, heat a drizzle of oil in a large frying pan on high heat. Season the steaks with salt and pepper.

Once 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 well done. IMPORTANT: Wash your hands and equipment after handling raw meat. The steak is safe to eat when browned on the outside.

Peas Please

Once cooked, transfer to plate and spread over the garlic thyme butter. Cover with foil and allow to rest for a couple of mins.

Meanwhile, wipe out (now empty) the frying pan and pop it back on medium-high heat with a drizzle of oil (no need to clean). 

Once hot, add the peas and chilli flakes (use less if you'd prefer things milder). Stir-fry for 2-3 mins.

Remove from the heat, season with salt and pepper, then stir through the mint.

Serve Up

When everything's ready, slice the steaks into 1cm thick slices and transfer to your plates. Spoon over any melted butter from the resting plates.

Serve with the peri peri chips and peas alongside.
