To cook pork in a slow cooker, follow these basic steps:

1. Season the pork with your choice of spices such as salt, pepper, garlic powder, onion powder, paprika, and optionally brown sugar or herbs.
2. (Optional) Sear the pork in a hot skillet with some oil for a few minutes on each side until browned. This adds flavor.
3. Place vegetables like onions, garlic, potatoes, and carrots in the slow cooker as a base.
4. Add some liquid such as broth, vinegar, soy sauce, or a BBQ sauce mixture.
5. Put the pork on top of the vegetables and liquids.
6. Cover and cook on LOW for about 8-10 hours or on HIGH for 4-7 hours until the pork is tender and easily pulls apart with a fork.
7. Optionally, thicken the cooking liquid into a gravy by mixing cornstarch with water, stirring it into the liquid, and cooking on HIGH for 10-15 minutes.
8. Let the pork rest a few minutes before slicing or shredding and serve with the vegetables and gravy or sauce.

Cooking low and slow is best for tender, juicy pork that falls apart easily. Using a meat thermometer, the pork is ideally cooked to an internal temperature of 195-205°F for full collagen breakdown and tenderness. Typical cuts used include pork shoulder or pork roast. This method works well for pulled pork, pork roast, or pork shoulder dishes in the slow cooker with various seasoning and sauce options.
