• Preheat oven to 240°C/220°C fan-forced. Boil the kettle. Cut potato into bite-sized chunks. • Half-fill a medium saucepan with boiling water, then add a generous pinch of salt. Cook potato in the boiling water, over high heat, until easily pierced with a fork, 10-15 minutes. • Meanwhile, finely chop garlic. Halve Brussels sprouts. Thinly slice carrot into sticks. Slice leek into 1cm thick rounds. • Season beef rump with salt and pepper. TIP: If your beef rump is thicker tahn 4cm, cut in half before seasoning.

• Drain the potatoes well then transfer to a lined oven tray. • Season generously with salt and pepper, drizzle with olive oil and toss to coat. Bake until tender, 20-25 minutes. TIP: Tossing and roughing the edges helps the potatoes get crisp edges while roasting!

• Meanwhile, in a large frying pan, heat a drizzle of olive oil over high heat. • When oil is hot, cook the beef, turning, for 3-6 minutes (depending on thickness), or until cooked to your liking. Transfer to a plate to rest. TIP: Cook in batches if your pan is getting crowded.

• While the beef is cooking, add Brussels sprouts, carrot and a splash of water to a microwave-safe bowl, then cover with a damp paper towel. • Microwave veggies on high until just tender, 2-4 minutes. • Drain veggies, then return to the bowl, season and cover to keep warm.

• While the beef is resting, wipe out frying pan then return to high heat with a drizzle of olive oil. • Cook leek, until slightly charred, 1-2 minutes each side. Add garlic and cook until fragrant, 1 minute. • Reduce heat to medium, then add the water, salt, butter and balsamic vinegar, tossing to combine. • Cover with a lid or foil, and simmer until tender and liquid has slightly thickened, 2-3 minutes.

• Slice steak. • Divide beef rump steak, twice-cooked potatoes, and steamed veggies between plates. • Top rump with braised leek and any remaining pan sauce. • Serve with mayonnaise. Enjoy!
