The reigning champions resumed their latest title defence with a comfortable 4-0 victory over the fourth-tier outfit at Stade de la Rabine.
Kylian Mbappe scored a second-half hat-trick – including his 150th goal for the club in all competitions – after Presnel Kimpembe broke the deadlock in the 28th minute.
PSG have now scored seven times without reply in their opening two matches of this season's competition.
Mbappe and Kimpembe were among only a handful of senior players to feature for the visitors as Pochettino handed youth an opportunity to impress.
And the head coach underlined the importance of giving his younger players exposure at a senior level.
During his post-match interview on Eurosport, he said: "Respect is always the most important thing, that's what I told the players.
"We were very professional, I am very happy with this performance of the team.
"The goal was to qualify for the next round, it's done.
"We have an incredible academy, it's important that they are on the pitch and that they can participate in this adventure of the first team.
"We have very, very good players, it's important for the club to have this pool.
"We will try to believe in them, to give them the opportunity to play."
Presnel Kimpembe was also on target for the defending champions, who remain unbeaten in 90 minutes in the competition since 2014.
The skipper headed the runaway Ligue 1 leaders in front after 28 minutes at Stade de la Rabine.
Mbappe then took centre stage after the break, striking three times to put the fourth-tier side to the sword.
Unbeaten against lower-league opposition in the Coupe de France since 2010, a much-changed PSG quickly imposed their authority on proceedings, enjoying over three-quarters of the possession.
The visitors, who have won six of the last seven editions of this competition, also registered eight shots inside the opening 25 minutes, with Kimpembe, Xavi Simons, Ander Herrera and Georginio Wijnaldum all drawing saves from Clement Petrel.
But there was no denying Kimpembe, who broke the deadlock with a free header from Nuno Mendes' corner.
Kimpembe turned provider 14 minutes after the restart, Mbappe latching onto his hopeful long ball and racing away before doubling the lead.
The France striker made it 3-0 in emphatic fashion in the 71st minute as he fired a stunning 20-yard effort into the top corner from Simons' pass.
That was the talisman's fourth brace in as many appearances for PSG in all competitions.
But hungry for more, he completed his hat-trick five minutes later, playing a neat one-two with Eric Ebimbe before sliding into the empty net.
