Pat dry the pork chops. In a large bowl, add the pork chops, chopped ginger, sliced shallot, salt, white pepper, oil, soy sauce, sugar, and lemon juice. Combine and marinade for at least 30 minutes or overnight. Keep the marinated pork chops in the refrigerator if marinating overnight.
Add one teaspoon of cornstarch to the marinated pork chops and mix well right before cooking.
In a large pan, heat two teaspoons of oil. If using a non-stick pan, there is no need to add oil. Sear the pork chops for 2 minutes on each side. Transfer the pork chops to a plate.
In the same pan, add a touch of oil, if needed. Sauté the sliced onions until they are soft, about 2 to 3 minutes. Season with sea salt and black pepper.
Add the chicken broth and bring it to a low simmer. Return the pork chops to the pan and simmer for 3 minutes.
While the pork chops simmer in the sauce, make a cornstarch slurry by mixing one teaspoon of cornstarch with one tablespoon of water.
Add the cornstarch slurry to the pan and incorporate. Cook for 2 minutes.
Finish with diced green onions and chopped parsley.
