How to Cook Top Round Roast?

Top round roast typically comes in a 4 to 6 pound cut of meat. It can be cooked in a 325 degree oven. Place roast on a rack in a shallow roasting pan. Cook for 1 1/2 to 3 hours, depending on the size, or until the internal temperature reaches 140 degrees for rare, up to 170 degrees for well done.
