Take your beef joint out of the fridge for 30 minutes prior to cooking to allow it to come to room temperature. Pat dry and drizzle with olive oil then season liberally with salt and pepper, a good 10 turns of the mill per side. Sprinkle with the seasoning.
Reduce the temperature to 350°F / 180°C and cook for a further 15 minutes per side. Check the core temperature with an instant read thermometer inserting the probe in the middle thickest part. If the beef is not quite done then continue cooking for a few more minutes (3-5).
