what temperature to cook roast beef too
Place the beef on top of the vegetables. To cook your beef: Place the roasting tray in the preheated oven. Turn the heat down immediately to 200Â°C/400Â°F/gas 6 and cook for 1 hour for medium beef. If you prefer it medium-rare, take it out 5 to 10 minutes earlier. For well done, leave it in for another 10 to 15 minutes.
