These carnitas come together quickly in the Instant Pot then are finished off in the oven to crisp.
If you want to make this in the slow cooker, simply put the seasoned pork in the slow cooker and cook for 5-6 hours on high or 8-10 hours on low, until it shreds easily with a fork. The pork will release plenty of juice as it cooks so you don't need to add any!
