Preheat your grill to 350°F.
Warm the maple syrup in the microwave for 20-30 seconds. Combine glaze ingredients, cover, and set aside.
Blot the pork chops dry with paper towels and brush them with a small amount of grapeseed or olive oil.
Combine the kosher salt, black pepper, onion powder, and garlic powder in a small bowl. Season pork chops evenly on both sides.
Place the chops on the grill and cook them for 18-20 minutes. Watch for flare-ups, adjust the heat, or move the chops to a cooler part of the grill and finish cooking indirectly.
Halfway through cooking, brush the glaze on the chops. Turn them, and repeat the process every few minutes, until all of the glaze is used.
Once the chops have reached an internal temperature of 145°F, remove them from the grill and loosely tent with aluminum foil. Let them rest for 5 minutes.
Serve these grilled maple pork chops garnished with your herb of choice.
Optional: Lightly drizzle chops with additional warmed maple syrup before serving.
