Step 1

Preheat oven to 250°C. Line a large roasting pan with baking paper. Arrange beef, potato and sweet potato in lined pan. Drizzle with half the oil, turning vegetables to coat. Season.

Step 2

Reduce oven to 200°C. Roast, turning the vegetables once, for 1 hour (or until the internal temperature of the beef is 60-65°C) for medium or until beef is cooked to your liking. Cover with foil. Rest for 10 mins.

Step 3

Meanwhile, place beans in a heatproof bowl and cover with boiling water. Set aside for 2 mins or until just tender. Drain well. Combine the basil, parsley, garlic and remaining oil in a small bowl.

Step 4

Drizzle beef with the basil mixture. Serve with the beans and vegetables.
