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, toss the halved baby potatoes with olive oil, garlic powder, smoked paprika, dried thyme, sea salt, and black pepper until every piece is evenly coated.
03 - Thread the seasoned potatoes onto skewers or arrange them in a grill basket to ensure even cooking and prevent them from falling through the grates.
04 - Place the potatoes on the grill and cook for 25 to 30 minutes, turning every 7 to 8 minutes, until the exteriors are crispy and lightly charred and the centers are fork-tender.
05 - Transfer the grilled potatoes to a serving platter. While still warm, sprinkle with chopped fresh parsley and grated Parmesan cheese if desired.
06 - Serve immediately alongside your favorite grilled entrées, burgers, or summer salads.
