Plan on oven-roasting the rump roast at 325 degrees Fahrenheit for about 28 to 33 minutes per pound for medium-rare meat, though the exact cooking time will vary depending on the roast's shape and size. Begin checking the meat after 45 minutes and continue checking it every 15 minutes after that.Remove it from the oven when a meat thermometer inserted into the thickest part of the roast registers 140 degrees Fahrenheit. For the slow cooker method, allow the roast to cook on the low setting for eight to 10 hours.hoto Credit Kathy Burns-Millyard/Demand Media.
