Preheat oven to 350 degrees (175 degrees C). Spray a shallow baking dish with non-stick spray. Set aside.
Sprinkle the Pork Chops (6) on both sides with the All-Purpose Seasoning (1 tablespoon). In a large skillet, melt Butter (1 tablespoon) over medium-high heat.
Brown the pork chops on each side. Cook one side for about 2-3 minutes.
Turn and cook the other side for another 2-3 minutes. Work in batches, and do not crowd the pan. Add more Butter (2 tablespoon) as needed to keep the pan greased.
Place the browned chops in a single layer in the bottom of the baking dish. Set aside.
In the same skillet you browned the pork chops in, add the remaining Butter (2 tablespoon) and the White Onion (3). Reduce heat to medium-low. Stir and cook the onions until they are golden and tender, about 10 minutes.
Stir in the Worcestershire Sauce (3 tablespoon) until well combined. Add the All-Purpose Flour (1/4 cup). Stir and cook for 2 minutes, until the flour is well incorporated.
Gradually stir in the Water (2 cup), Salt (1/2 teaspoon), and Ground Black Pepper (1/2 teaspoon). Cook and stir until thickened and bubbly. Taste and adjust seasonings as desired.
Pour the onion gravy over the pork chops. Cover the pan with foil, and bake for 30 to 40 minutes. Cooking time will vary based on the thickness of your pork chops.
