Secure the lid on the slow cooker. Cook on HIGH for 4 to 6 hours or on LOW for 6 to 8 hours. Check with a meat thermometer; pork is ready when it reaches 90°C and shreds easily with a fork.

Carefully shred the cooked pork in the slow cooker using two forks or transfer to a cutting board and shred, reserving all juices. If not serving immediately, refrigerate pork and juices in an airtight container until ready to finish.

Heat a medium skillet over medium heat. Add a small drizzle of avocado oil and warm until shimmering. Spread a single layer of shredded pork in the skillet, adding a spoonful of reserved cooking juices. Cook until the liquid evaporates and the bottom is browned and crispy, about 2-3 minutes. Flip and brown the other side. Transfer to a large bowl.

Continue searing remaining pork in batches. Once all carnitas are seared, drizzle a little of the cooking juices over the meat and serve immediately as desired.
