Set the oven to Broil or 500°F.
Place the ribs back in the oven, uncovered, for approximately 5 minutes.
Remove the ribs, carefully flip them over, and brush the other side with BBQ sauce.
Return them to the oven for another 3–5 minutes, or until the BBQ sauce is caramelized and slightly charred.
Watch closely during this step—the sauce can burn quickly.
