Cooking Steps

Roast the chat potatoes
1

• Preheat oven to 240°C/220°C fan-forced. • Halve chat potatoes. • Place potatoes on a lined oven tray. Drizzle with olive oil, season with salt and pepper and toss to coat. • Roast until tender, 25-30 minutes.

2

• Meanwhile, chop broccoli (including stalk!) into small florets. Trim green beans. Finely chop garlic. Pick thyme leaves. • In a medium bowl, combine savoury seasoning, a drizzle of olive oil and a pinch of salt and pepper. Add rump steak, turning to coat.

3

• In a large frying pan, heat a drizzle of olive oil over medium-high heat.
• When the oil is hot, cook porterhouse steak for 3-4 minutes each side for medium-rare, or until cooked to your liking. Using tongs, hold steak upright and sear fat until golden, 1 minute.
• Remove steak from pan, cover and rest for 5 minutes. Season with salt and pepper.

• Return frying pan to medium-high heat with a drizzle of olive oil. • Cook broccoli and green beans, tossing, until tender, 6-7 minutes. • Add half the garlic and cook until fragrant, 1 minute. Transfer to a bowl, season with salt and pepper and cover to keep warm. 

5

• Wipe out frying pan and return to medium-high heat with a drizzle of olive oil. • Add remaining garlic and thyme and cook until fragrant, 1 minute. • Stir in thickened cream, Dijon mustard (see ingredients), Worcestershire sauce, the salt and any beef resting juices, then simmer until slightly thickened, 1-2 minutes. Season with pepper.

• Thinly slice porterhouse steak. • Divide seared porterhouse steak, roasted chat potatoes and garlicky greens between plates. • Pour Diane sauce over beef to serve. Enjoy!
