01 - Set your grill to medium-high heat, targeting approximately 400°F. Allow the grates to fully heat before adding the potatoes.
02 - In a large mixing bowl, combine the halved baby potatoes with olive oil, garlic powder, smoked paprika, dried thyme, sea salt, and black pepper. Toss thoroughly until every piece is evenly coated with the seasoning mixture.
03 - Thread the seasoned potatoes onto metal or soaked wooden skewers, or arrange them in a single layer inside a grill basket to promote even cooking and prevent smaller pieces from falling through the grates.
04 - Place the potatoes on the hot grill and cook for 25 to 30 minutes, turning them every 7 to 8 minutes with tongs. Continue grilling until the exteriors develop a crispy, lightly charred crust and the centers yield easily when pierced with a fork.
05 - Transfer the grilled potatoes to a serving platter. While still warm, sprinkle generously with chopped fresh parsley and grated Parmesan cheese if desired.
06 - Present immediately alongside grilled meats, burgers, or fresh summer salads. These potatoes are best enjoyed hot off the grill.
