Cooking Steps

Roast the beef Make the mashed potato
1

• Preheat oven to 220°C/200°C fan-forced. In a large frying pan, heat a drizzle of olive oil over high heat. • Season premium sirloin tip all over and add to hot pan. Sear until browned, 1 minute on both sides. • Transfer to lined oven tray and roast for 17-22 minutes for medium or until cooked to your liking. • Remove from oven and cover with foil to rest for 10 minutes. TIP: The meat will keep cooking as it rests!

Make the mash
2

• Meanwhile, boil the kettle. Half-fill a large saucepan with boiling water, then add a generous pinch of salt. • Peel potato and cut into large chunks. Cook potato in the boiling water, over high heat, until easily pierced with a fork, 12-15 minutes. • Drain and return to the pan. Add the butter and the milk to potato and generously season with salt. Mash until smooth. Cover to keep warm. TIP: Save time and get more fibre by leaving the potato unpeeled.
