How long do you cook a Boston pork roast?

A Boston pork roast, often referred to as a pork shoulder, should be cooked low and slow for optimal tenderness. Typically, it takes about 1.5 to 2 hours per pound at 325°F (165°C) in the oven. For best results, use a meat thermometer to ensure it reaches an internal temperature of at least 190°F (88°C) for pull-apart tenderness. Alternatively, slow-cooking methods can take 8-10 hours on low in a slow cooker.
