Blues boss Tuchel, who came into the match having won seven and drawn three since taking over for Frank Lampard, handed a start to fit-again Kai Havertz, while U.S. international Christian Pulisic once again did not make the XI.
Callum Hudson-Odoi’s stellar first-half play led to Chelsea’s opener when he sprang Marcos Alonso in the penalty area to square to Havertz for a shot that deflected off Ben Godfrey and into the net for an Everton own goal.
Alonso was in on goal again before half-time with a stellar chance to double the home side’s lead, but Everton keeper Jordan Pickford made a great reaction save on the Spaniard’s snap shot and Chelsea settled for a 1-0 lead at the break.
Jorginho doubled Chelsea’s lead with a penalty kick in the 65th minute, sending Pickford the wrong way after the Everton keeper hauled down Havertz in the area to gift the hosts a chance from the spot.
The result leaves Chelsea, who have kept nine clean sheets since Tuchel took the job, on 50 points from 28 matches, four ahead of fifth-placed Everton and three behind third-placed Leicester City.
