Season both sides of the pork chops with salt and pepper.
In a large, oven-safe skillet, heat the olive oil over medium-high heat.
Add the pork chops and sear for 2-3 minutes on each side, until golden brown. Transfer the pork chops to a plate and set aside.
In a small bowl, whisk together the apple cider, Dijon mustard, brown sugar, and apple pie spice.
Reduce the heat to medium-low and add the minced garlic to the same skillet used for searing the pork chops. Sauté for about 30 seconds, or until fragrant.
Pour the apple cider mixture into the skillet and bring it to a simmer, stirring occasionally. Cook for 2-3 minutes, until the mixture thickens slightly.
Add the butter to the skillet and stir until melted and combined with the glaze.
Return the seared pork chops to the skillet, spooning the glaze over the top of each chop.
Transfer the skillet to the preheated oven and bake for 8-10 minutes, or until the pork chops are cooked through and reach an internal temperature of 145°F.
Remove the skillet from the oven and let the pork chops rest for 5 minutes before serving.
Serve the pork chops hot, garnished with fresh thyme sprigs, and spoon any remaining glaze from the skillet over the top.
Notes
Pork chops: You can substitute bone-in pork chops that are about the same thickness. Bone-in pork chops will need longer in the oven, so adjust the cooking time accordingly and cook until the pork chops reach 145F.
Apple cider: Be sure to use apple cider, either fresh or bottled, and not apple cider vinegar.
Brown sugar: Feel free to adjust the sugar according to your tastes.
Apple pie spice: The spices add a nice warmth to the sauce. You can substitute cinnamon for the spice blend.
Dijon mustard: The mustard helps to balance out the sweetness of the apple cider and sugar. Either brown mustard or stone ground mustard would make a good substitute.
