Cooking Steps

Get Prepped
1

Preheat your oven to 220°C/200°C fan/gas mark 7.

Remove the butter and steaks from the fridge to allow them to come up to room temperature.

Pick the rosemary leaves from their stalks and roughly chop (discard the stalks). 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, season with salt, pepper and half the rosemary, then toss to coat. Spread out in a single layer. TIP: Use two baking trays if necessary.

Cook the Chips and Garlic
2

Pop half the garlic (unpeeled) into a small piece of foil with a drizzle of oil and scrunch to enclose it. Add the garlic parcel to the chip tray.

When the oven is hot, roast the chips on the top shelf until golden, 25-30 mins.

Meanwhile, peel and grate the remaining garlic (or use a garlic press). Halve any thick broccoli stems lengthways. Trim the bottom 2cm from the asparagus and discard.

Bring on the Veg
3

Pop the Tenderstem® broccoli and asparagus onto a baking tray. Drizzle with oil, scatter over the grated garlic and season with salt and pepper, then toss to coat. Spread out in a single layer. 

When the chips are halfway through cooking, turn them. Remove the garlic parcel and set aside to cool.

Return the chips to the oven for the remaining time. At the same time, roast the veg on the middle shelf until tender and crispy, 10-12 mins.

Make your Garlic Butter
4

Once the garlic has roasted and cooled, cut the end with scissors, squeeze it out of the skin and mash with a fork.

Pop the mashed garlic into a small bowl with the butter and remaining rosemary. Season with salt and pepper, mix well, then set your garlic butter aside.

When the chips have 5 mins remaining, sprinkle over the hard Italian style cheese and return to the oven for the remaining time.

Fry the Steaks
5

Put the frying pan on high heat with a drizzle of oil. Season the steaks with salt and pepper.

Once very hot, lay the steaks into the pan and fry until browned and medium-rare, about 6-8 mins depending on their thickness. Turn halfway through. TIP: Cook each side for 1 min more if you like it more well done.

Once cooked, transfer the steaks to a plate. Spoon over the garlic butter, cover with foil and allow to rest for a couple of mins. IMPORTANT: Wash your hands and equipment after handling raw steaks. They're safe to eat when the outside is browned. 

Finish and Serve
6

Once rested, thinly slice the steaks and transfer to your plates. Spoon over any buttery juices from the resting plate.

Serve with the cheesy rosemary chips and garlicky broccoli and asparagus.

Enjoy!
