Quick Answer. It takes 9 to 10 hours to cook a 3-pound beef top round roast in a Crock-Pot at the low setting. The roast only requires about 5 hours of cooking time at the high setting, but this tough cut of meat isn't recommended for cooking on the high setting. The faster cook time and higher temperature doesn't break down the tough meat fibers and leaves the roast tough.
3. Place top round roast, fat side up, on rack in shallow roasting pan. Do not add water or cover roast. 4. Cook in in the oven for about 2 1/2 hours or until the internal temperature reaches 140Â°F for medium-rare or 155Â°F for medium.
