The Belgian was given three weeks off after his exploits at the World Cup and was only named on the bench at the Kirklees Stadium, but he made a massive impact when he was finally brought on in the second half.
Pedro added the icing on the cake with 10 minutes left, having been teed up by Eden Hazard - who came on as a substitute and immediately went about tormenting Huddersfield defenders.
The Italy global, who was shaking his head in disbelief at Hazard's ability, made an immediate beeline for his new teammate as he got back on his feet.
But the Terriers were dealt a hammer blow in the 44th when referee Chris Kavanagh awarded the visitors a penalty.
It would do a discredit to the style of play to say Chelsea began to fully embrace "Sarriball" in the second half, but there was certainly a more attacking approach adopted as Chelsea looked to put the game out of sight.
Alex Pritchard was a risky creative force in the final third, Steve Mounié came close on three occasions and hit the post with a close-range header just minutes after Kanté opened the scoring.
Kawhi Leonard breaks silence to thank Spurs, Gregg Popovich
THANK YOU to the fans! "There is not a more passionate or dedicated fan base than what I've witnessed in San Antonio ", he wrote . He only appeared in nine games last season before sitting out the entire campaign due to a quad injury.
And when the crosses did come in, Morata could not get himself on the end of them, being crowded out well by the Huddersfield defence.
"I fully understand the fans of Chelsea and no one has reason to blame that feeling". In the first line, we defended not like we wanted to defend.

"I am very happy because in the first part of the season for us it is not easy to gain points".
"We were in trouble for 15 minutes against a physical team, we are not a physical team".
Eden Hazard wasn't even involved much in the game, coming on late in the second half to gain some match fitness ahead of Arsenal next week.
