Begin by spraying the interior of the slow cooker with non-stick cooking spray to prevent the pork from sticking. Place the pork butt roast in the slow cooker.

Evenly sprinkle the coarse salt over the pork, ensuring it is generously rubbed into the meat. Then, pour the liquid smoke over the salted roast.

Cover and cook the pork on the low setting for 16-20 hours. Be sure to turn the roast halfway through the cooking process for even heat distribution.

Once the pork has fully cooked, remove it from the slow cooker and shred the meat using two forks, discarding any fat as you shred. Return the shredded pork to the slow cooker to absorb the flavorful juices from the bottom.

Serve the tender, flavorful pulled pork over a bed of rice or in a bun for a satisfying meal.
