Willian opened the scoring in the 25th minute through a long-range strike and Chelsea's lead was doubled just seven minutes later, courtesy of a Martin Kelly own-goal.
Patrick van Aanholt pulled a consolation goal back late on but the defeat leaves Crystal Palace in the relegation zone in 18th, one point from safety.
