Preheat your oven to 325°F (165°C). Pat the pork chops dry with paper towels. Season both sides generously with salt and pepper, pressing the seasonings into the meat.
Heat the vegetable oil in a large skillet over medium-high heat until shimmering. Working in batches to avoid overcrowding, sear the pork chops for 2-3 minutes per side until they develop a golden-brown crust.
In a mixing bowl, whisk together the condensed mushroom soup, milk, and Worcestershire sauce until smooth. Fold in the sliced onions, mushrooms, thyme, garlic powder, and paprika.
Arrange the browned pork chops in a 9x13 inch baking dish, slightly overlapping if necessary. Pour the soup mixture evenly over the chops, ensuring each one is well-coated. Cover the dish tightly with aluminum foil.
Bake the covered dish for 1 hour, or until the pork reaches an internal temperature of 145°F (63°C). Remove the foil during the last 15 minutes of cooking to allow the sauce to thicken slightly.
Let the dish rest for 5-10 minutes before serving to allow the juices to redistribute throughout the meat.
