Photo Credit Kathy Burns-Millyard/Demand Media. 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.o keep the rump roast's juices sealed inside the meat while it is cooking, heat a large skillet over medium-high heat and sear each side of the roast until all are light brown, about 1 1/2 to 2 minutes per side.
