1 Cook the beef at 200F until its internal temperature reads 25-30 degrees below the desired doneness. This can take 4 to 8 hours depending on the size of the roast, and how cooked you like it.  Turn the heat up to 500F and cook it until it reaches 5 to 10 degrees below the desired doneness.
For a rare roast: Allow 15 minutes of cooking time for every pound of roast. For example, if you had a 5 pound roast, you would cook your roast for 75 minutes if you wanted it rare. For a medium rare roast: Cook the roast for 20 minutes for every pound. If you were cooking a 5 pound roast, you would cook it for 100 minutes. For a medium roast: Allow 22 minutes of cooking time for every pound. If you were cooking a 5 pound roast, you would cook the meat for 110 minutes. If you are cooking a pork roast, you should allow 20 minutes per pound of meat.
