Daniel Farke’s side were dominant under the Saturday night lights at Elland Road, blowing away a lacklustre Palace side.
Dominic Calvert-Lewin notched a first-half brace, meaning he is heading into Christmas having scored six goals in his last five games.
Ethan Ampadu extended the advantage, coolly slotting past Dean Henderson with a finish worthy of a forward.
Justin Devenny converted a late penalty to deny Leeds a shut-out, although Anton Stach’s stunning free-kick restored the three-goal advantage.
