To achieve perfectly cooked roast beef at 180 degrees Celsius (350 degrees Fahrenheit), a general rule of thumb is to cook it for approximately 20 minutes per pound, plus an additional 20 minutes for medium-rare. For medium, aim for about 25 minutes per pound. Always use a meat thermometer to ensure the internal temperature reaches 135°F for medium-rare or 145°F for medium. Let it rest for about 15 minutes before slicing to redistribute the juices.
