1. Heat grill to high, then clean and oil grates. Grill patties, without moving, until browned, 3 to 5 minutes. Flip patties and continue to grill until second side is browned and centers register 125 degrees for medium-rare, 3 to 5 more minutes.
2. Top each burger with a slice of cheese, close grill, and cook until cheese melts, about 30 seconds; transfer to a plate and let rest 5 minutes. Lightly toast split sides of rolls on grill. Transfer patties to rolls and top evenly with barbecue sauce and crispy onions.
