In a small bowl, combine the onion powder, garlic powder, black pepper, seasoned salt, thyme, and smoked paprika. Pat the pork chops dry, lightly coat both sides with olive oil, then generously season both sides with the spice mixture. Set aside while preparing the glaze.
Melt 2 tablespoons butter in a skillet over medium heat. Add the sliced peaches and cook for 3-4 minutes, until softened and lightly caramelized. Stir in the minced garlic and cook for about 30 seconds, until fragrant.
Add the brown sugar, balsamic vinegar, Worcestershire sauce, smoked paprika, salt, and pepper. Stir well to combine, then simmer for 4-5 minutes, stirring occasionally, until the glaze slightly thickens. Remove from the heat and stir in the lemon juice.
Heat a cast iron skillet over medium-high heat and add enough oil to lightly coat the bottom. Add the pork chops and cook for 2-3 minutes on the first side, then flip and cook for another 2-3 minutes on the second side.
Add 1 tablespoon butter to the skillet and spoon the melted butter over the pork chops as they finish cooking. During the final minute, brush the peach glaze onto the pork chops, then flip and glaze the other side.
Cook until the pork chops reach 142-145°F. Remove them from the skillet and let rest for 3 minutes, keeping in mind the temperature will continue to rise slightly as they sit.
Spoon the additional peaches and glaze over the pork chops before serving.
