Pour 1/3 of the BBQ sauce over the ribs. Using tongs, flip the ribs over and spoon another 1/3 of the sauce over top. Reserve the remaining BBQ sauce to spoon over the cooked ribs. Cover the pan with aluminum foil and roast for 2 hours.
Remove the foil, pour the remaining BBQ sauce over the ribs and cook for 30 minutes more, uncovered, until the meat is tender and browned. Cut off any excess fat that remains around the short ribs. Let cool for about 15 minutes.
