Mix the seasoning. In a small bowl, combine the paprika, garlic powder, onion powder, dried thyme, salt, and black pepper.
Season the pork chops. Pat the pork chops dry with paper towels, then season them generously on both sides with the spice mixture.
Preheat the oven. Preheat the oven to 425°F (220°C).
Sear the pork chops. Heat the olive oil and butter in a large cast-iron skillet over medium-high heat. Once the butter has melted and the skillet is hot, add the pork chops. Sear for about 2–3 minutes per side, until deeply golden. Transfer the pork chops to a plate.
Cook the onion. Reduce the heat to medium. Add the finely chopped onion to the same skillet and cook for about 4 minutes, stirring occasionally and scraping up the browned bits from the bottom, until the onion begins to soften.
Add the garlic. Stir in the minced garlic and cook for about 30 seconds, just until fragrant.
Add the broth. Pour in the chicken broth and Worcestershire sauce. Stir well, scraping up any remaining browned bits from the bottom of the skillet.
Add the rice and seasonings. Stir in the uncooked long-grain rice, then add the dried thyme, salt, and black pepper. Mix well so the rice is evenly distributed in the broth.
Transfer to the baking dish. Pour the rice and broth mixture into a baking dish and spread the rice into an even layer. Arrange the seared pork chops over the rice and pour in any juices that collected on the plate.
Cover and bake. Cover the baking dish tightly with foil. Bake at 425°F (220°C) for 30–35 minutes, until the rice is tender and has absorbed most of the broth.
Finish uncovered. Remove the foil and bake for another 5 minutes, allowing the pork chops to regain some color and any excess moisture on top of the rice to evaporate.
Rest and serve. Remove the dish from the oven and let it rest for 5–10 minutes. Fluff the rice gently with a fork, sprinkle with chopped fresh parsley, and serve the pork chops over the savory rice.
