Angel Di Maria struck twice inside the opening quarter-hour at the Parc des Princes before the Argentine provided the cross for Cavani to net his 156th PSG goal.
Neymar marked his return from a rib injury with the hosts' fourth just before half-time, and the Brazilian made it a hat-trick with two more second-half strikes as Dijon were mercilessly ripped apart.
Kylian Mbappe piled on further misery for the visitors 13 minutes from time before Neymar notched his fourth of the evening from the penalty spot, denying Cavani the chance to make club history and eliciting whistles from home supporters.

"(Cavani) is our goalscorer and he's improved a lot here. The team helped him to achieve this individual mark, i think Neymar took the penalty because it was also a good day for him. We're happy with it. But there will be lots more chances for Cavani to score more goals. " Said PSG coach Unai Emery, who was quick to defend Neymar's decision to take the spot-kick.
Argentine Di Maria, who grabbed the winner in Sunday's 1-0 victory at Nantes, needed just four minutes in Paris to put the home team ahead with a stunning left-footed strike into the top corner.
The former Real Madrid and Manchester United winger added a second when he applied the final touch after Neymar lifted the ball over Dijon goalkeeper Baptiste Reynet following a ball through from Cavani.
The Uruguayan then netted his league-best 20th goal of the season by heading in a right-wing cross from Di Maria, pulling level with the record Ibrahimovic set across four seasons in the French capital.
Neymar made it 4-0 on 42 minutes with a sublime free-kick, with the world's most expensive player pouncing on a miscued clearance to double his tally just before the hour.
He then struck a sensational third goal of the night with a run that beat several Dijon defenders and culminated in a crisp low drive from the edge of the area.

We were almost perfect today," PSG defender Thomas Meunier told Canal+.
