Marinate the Korean style ribs – In a large glass dish or pan, lay the Korean style ribs in the dish and pour the roasted garlic teriyaki sauce over the ribs, ensuring they are completely covered and submerged. Allow the ribs to marinate for at least two hours and up to overnight.
Set up your Weber Kettle for direct grilling – Fill your charcoal chimney fire starter with charcoal briquets, and when ready, empty the chimney in the center of the charcoal grate and, with tongs, spread them around to form a neat pile.
Place the Korean style ribs on the grill grate – Take the Korean style ribs out of the marinade and let the excess marinade drip off. Place the ribs directly over the charcoal coals and grill for approximately 10 minutes, depending on the intensity of your heat. Flip and rotate the ribs until a nice, caramelized char is achieved.
Remove the Korean style ribs from the Weber Kettle – Place the Korean style ribs on a serving tray, sprinkle with the chopped green onions, and serve.
