Directions

1. Preheat the oven to 350 degrees F.
2. Meanwhile, season the pork with salt and pepper. In an oven-ready skillet, braising pan, or Dutch oven large enough to comfortably hold the pork with the lid on, warm the oil over medium-high heat. Add the pork and cook until well-browned on all sides, 10 to 12 minutes. Transfer the meat to a plate or platter and set aside.
3. Add the enchilada sauce to the skillet and bring to a boil, scraping up any browned bits (careful—it may splatter). Return the pork to the skillet, along with any accumulated juices, and return to a boil. Cover the skillet, place it in the oven, and cook for 1 hour.
