With one eye on their midweek trip to the Nou Camp, PSG coach Carlo Ancelotti opted to rest some of his star names including David Beckham, Javier Pastore, Ezequiel Lavezzi and Lucas Moura from his starting line-up.
But, despite that, second-half goals from Jeremy Menez and Zlatan Ibrahimovic - the latter teed up by substitute Beckham proved enough to claim all three points and keep the capital club a healthy distance clear of second-placed OM, who beat Bordeaux 1-0 on Friday night.
Substitute Kevin Anin grabbed a dramatic stoppage-time winner as Nice boosted their European hopes with a thrilling 4-3 success at Toulouse.
The game was finely poised at 2-2 at the interval, Eric Bautheac starting and finishing the first-half scoring with Wissam Ben Yedder and Etienne Capoue on target for the hosts in between.
Dario Cvitanich's strike midway through the second half restored the visitors' lead, but Ben Yedder's second of the game got Nice back level only for Anin to edge TFC ahead again at the death.
As if the goal action was not enough to keep the crowd on the edges of their seats, there were also late red cards for Toulouse goalkeeper Ali Ahamada and Nice substitute Alexy Bosetti to add further spice to the occasion.
Montpellier also revived their European bid with a 3-1 triumph over free-falling Valenciennes at the Stade de la Mosson.
Second-half goals from Daniel Congre and Younes Belhanda ensured the defending champions ended a three-game winless run.
It also closed the gap on the European places, with fourth-placed Nice three points ahead, although St Etienne and Lille could extend that gap tomorrow.
Valenciennes, who have now won just once in 13 games, had gone into half-time level when Opa Nguette cancelled out Souleymane Camara's 18th-minute opener.
Elsewhere, relegation-threatened Brest slumped to a fourth successive defeat in Corentin Martins' first match in charge, with Florian Thauvin scoring twice in Bastia's 4-0 victory.
Martins took over on an interim basis when Landry Chevin was sacked last week but was unable to arrest the slide.
It took Bastia 41 minutes to break the deadlock through Wahbi Khazri, but they had time to add three more as Thauvin's brace and Anthony Modeste's penalty punished the visitors, who also lost goalkeeper Joan Hartock to a late red card.
Nancy secured their third straight league win with a 1-0 home victory over fellow strugglers Troyes.
Substitute Romain Grange scored the game's only goal seven minutes after coming on to lift the hosts to within a point of safety.
Finally, Sochaux and Ajaccio both remained precariously placed just above the relegation zone after battling out a 0-0 draw at the Stade Auguste Bonal.
