Cabaye joined PSG from Newcastle United in the January transfer window and came off the bench to make his debut in the 2-0 win over Bordeaux in Ligue 1 on Friday night.
"With all due respect to him (Cabaye), I had never seen him play before," Ibrahimovic told beIN Sport.
"But he came on during the game and did good things. The more good players we have, the better for us. We will need everyone."
PSG face Nantes in the Coupe de la Ligue semi-final on Tuesday.
