According to McDonald's official website, McDonald's Plate Roasted Chicken Thigh Meat is prepared using a special cooking method, in which the chicken is first cut into appropriately sized chunks, and then marinated for a certain period of time in McDonald's unique marinade, and then placed in the oven for roasting. During the roasting process, both sides of the chicken thigh meat of the Plate Grilled Chicken are subjected to high-temperature frying, resulting in the formation of a charred crust on the surface of the chicken, while the interior maintains the tenderness and juiciness of the chicken. When the McDonald's Plate-Broiled Chicken Thighs are ready, they are arranged in front-to-back, right-to-left order in boxes, with a maximum of 8 slices per box.
