Preheat oven to 325℉.
Trim any excess fat from the pork before cutting it into 4 pieces of the same size. Pat dry with a paper towel and season all sides with the salt and pepper.
Prepare the braising liquid in a 2-quart bowl. Add the apple cider, chicken broth, Dijon mustard, dehydrated onion, minced garlic, rosemary, and thyme. Mix and add sliced onions. Set aside.
Add oil to a small Dutch oven. Heat over high heat and place the meat pieces in when hot. Reduce the heat to medium-high and sear the pork on all sides until the meat is browned.
Add the braising liquid, making sure meat pieces are covered. Cover the Dutch oven with the lid and place it in the preheated oven.
Flip the meat at 1 hour. Check for tenderness of meat at 2 1/2 hours. It should be nearly fork-tender. Mix in the apple slices and cook for 10-15 minutes. Pork should be fork-tender as well as the apples.
Remove the Dutch oven from the oven. Taste and adjust for seasonings.
If you would like to make a gravy from the braising liquid, remove the pork, onion, and apples, and keep them warm. Add 1 tsp of cornstarch to 1 tsp of water and mix to make a slurry. Place the Dutch oven on the stovetop and heat on medium heat. Add slurry and whisk until thickened, about 2 minutes. You can add meat, onion, and apples back into the gravy or serve them separately.
