Searing the pork first is optional. If doing so, season with salt and pepper and sear 2-3 minutes per side in a large skillet over high heat.
To the slow cooker, add water, salt, black pepper, garlic powder, onion powder, oregano, and chipotle chili powder. Whisk until blended.
Add the pork to the Crockpot, turning to coat each side. Allow to cook on LOW for 8-10 hours or high for 4-6 hours or until a thermometer registers 200ºF.
Preheat the oven to 350ºF. Transfer pork to a cutting board or large bowl. Remove and discard any excess fat and bone. Shred meat with 2 forks, set aside.
Mix the two cheeses together. Pour ¾ cup of the enchilada sauce in a 9”x13” baking dish and the remaining sauce into a bowl.
Assemble enchiladas starting with a tortilla, followed by ⅓ cup shredded pork, ¼ cup cheese, a pinch of cilantro, and 1 tablespoon of the enchilada sauce. Roll and place in a baking dish.
Once all of the enchiladas are made, sprinkle pour the remaining enchilada sauce on top and spread evenly. Sprinkle on the remaining shredded cheese. Cover with aluminum foil, and bake for 35 minutes.
Remove the foil and bake for an additional 15 minutes. Set the oven to broil for another 3-5 minutes or until the cheese has melted and browned.
Rest 5-10 minutes before serving.
