Marco Verratti drilled in a low finish, Kylian Mbappe added a penalty - having earlier missed a retaken spot-kick - and Dani Alves lobbed home the third.
Kalifa Coulibaly was sent off for Nantes for two yellow cards.
PSG are running away with the Ligue 1 title and come up against 10th-placed Rennes, who progressed after beating Lyon 3-2 on Tuesday.
