at what temperature is a roast beef at when it's done
Judge your estimated cooking time by the recipe or on a basis of 20 minutes per pound of roast. Remove the roast from the oven when it reads 5 to 10 degrees lower than the desired end temperature, since it will continue to cook after it comes out of the oven. Very large restaurant-style roasts can increase as much as 20 degrees after being removed from the oven. Decide what level of doneness you desire. Beef roast is rare at 120 to 130 degrees Fahrenheit, medium-rare at 130 to 135, medium at 135 to 145 and well-done at 160 degrees Fahrenheit.
