Coach Carlo Ancelotti kept Ibrahimovic on the bench until the 65th minute and PSG struggled to play with fluency in the first half, even though striker Kevin Gameiro hit the post midway through.
With Ibrahimovic warming up, Menez scored in the 56th with a shot which goalkeeper Mickael Landreau should have saved. Ibrahimovic then added a penalty in the 71st to notch his 21st league goal in as many games this season.
Wahbi Khazri pulled a goal back from a free kick in the 83rd before Lavezzi sealed the win in the 89th.
Lyon needs to beat Lille at home on Sunday night to close the gap on PSG to three points, while Marseille must win at Evian to pull within six points of PSG.
Defender Sylvain Marchal almost scored an own goal when he cut out Lucas' cross and the ball rolled just wide, and former PSG goalie Landreau made a smart stop to keep out Gameiro's back-heeled volley.
But Landreau then made a mistake, failing to properly gather Menez's tame shot, and allowing it to squeeze under him.
Landreau was beaten again when Lucas was fouled by Julian Palmieri and PSG was awarded a penalty, although the infringement looked to be outside the penalty area.
It was not a night for goalies as Salvatore Sirigu was beaten by Khazri's free kick while he was still organizing his wall _ the first goal the Italian `keeper has conceded in 951 minutes since the 2-1 home loss to Rennes on Nov. 17.
Khazri almost equalized moments later as Bastia pushed forward, but Lavezzi sealed the win when he turned in Clement Chantome's cross in the 89th.
