Preheat your oven to 425°F and line a large sheet pan with parchment paper.
Toss the potatoes with olive oil, garlic powder, paprika, thyme, salt, and pepper. Spread them on the sheet pan.
Roast the potatoes for 20 minutes to give them a head start.
Season the pork chops on both sides with salt and pepper. Nestle them onto the pan with the potatoes.
Return the pan to the oven and roast for another 18 to 22 minutes, flipping the pork chops halfway through, until they reach 145°F internally.
Remove from oven, let the pork chops rest for 5 minutes, sprinkle with parsley, and serve warm.
