1 Cut two pieces of aluminum foil, each 24 inches long, and set aside.  Toss the potatoes, onions, parsley, oil, garlic, salt, and pepper in a large bowl. Place one half of the potatoes in the center of one foil strip and fold the right and left sides of the foil in toward the center to cover the potatoes.
1 To get a crispy potato skin on a whole potato, take your grilled baked potatoes out of the foil after 20-30 minutes and put them directly on the grill for the last 10 minutes of cooking time.. Cook your potatoes. Adjust your grill to medium heat and cook for 5 to 6 minutes and turn to the other cut side. Cook on second side for 5 to 6 minutes and then turn wedges so the skin side is down.
