what temp should roast beef be cooked to
Step 1. Preheat your oven to 325 degrees Fahrenheit for a pot roast from the round; 425 degrees for a pot roast from the chuck; and 350 degrees for a pot roast from the rib. The weight and type of roast determines the cooking time; you should cook a roast until its internal temperature is between 135 and 150 degrees F. For instance, a 2- to 3-lb. rump roast cooks for 1 Â½ to 2 hours to medium-rare doneness, the Cattlemen's Beef Board and National Cattlemen's Beef Association website advises.
