Place the beef onto a ovenproof tray. Pat dry with kitchen roll.

Blitz all the rest of the ingredients in a blender until it forms a smooth paste like mixture.

Turn your oven on to 180c.

Transfer to the oven and roast the beef until cooked through. I don't know how long it took to cook through as I used a meat thermometer and I really wasn't keeping track of timings for this recipe but I think it took around 60 minutes to 90 minutes to cook through.

Allow to rest for 10-20 minutes before serving.
