Cooking the perfect roast beef requires precision and timing. One of the key factors in achieving that juicy, tender roast is knowing the right cooking time. The Cooking Time for Roast Beef Calculator is a handy tool designed to take the guesswork out of the equation and ensure your roast beef is cooked to perfection every time.


The calculator employs a simple yet effective formula to determine the cooking time for your roast beef based on its weight. The general rule of thumb is to cook the beef at 325°F (163°C) for 20 minutes per pound (450 grams) for medium doneness. However, it’s important to note that cooking times may vary depending on factors such as the type of cut, desired doneness, and individual oven characteristics.
