Preheat oven to 375°F (190°C).
Season both sides of the pork chops with salt, pepper, garlic powder, and onion powder.
In a large skillet over medium-high heat, sear the pork chops in vegetable oil for 3 minutes per side until golden brown; remove from heat.
In a 9x13 inch baking dish, whisk together the rice, condensed soup, chicken broth, and diced onions until well combined.
Place the seared pork chops on top of the rice mixture.
Cover the dish tightly with aluminum foil to prevent moisture from escaping.
Bake for 45 minutes or until the rice has absorbed the liquid and the pork reaches an internal temperature of 145°F (63°C).
Remove from oven and let rest, covered, for 5 minutes before serving.
