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.
How long should you cook a 4-1/2-lb. pork shoulder or butt roast? Per our usual nagging, you should cook it until an instant-read thermometer inserted into the thickest part of the roast measures 160Â°F (70Â°C).ome people like their pork roasts less well done, but the USDA won't have it. In a 325Â°F (160Â°C) oven, it will take between 35 and 40 minutes per pound to reach a center temperature of 160Â°. So you could check it after 2-1/2 hours, but it may take as long as 3 hours.
