In the slow cooker, it takes between 8 – 10 hours on low heat. When cooked for 10 hours on low heat, the meat can be easily shredded into tiny thread-like pieces with two forks. However, if you don’t like this texture the pork can be cooked for a shorter time. Cooking the pork for about 8 – 9 hours will make the meat soft and just starting to fall apart. It can be pulled apart with forks. There will be some resistance as you pull the meat apart, and the pulled meat will be slightly thicker than the meat cooked for 10 hours.
