Andersen (pictured at a TransferRoom Summit) has been Head of Scouting at AGF since July 2021, having joined the club five years earlier as a First Team Analyst.
He began his career in football as a match analyst with FC Midtjylland.
The move reunites Andersen with FC Copenhagen Sporting Director Peter Christiansen.
Christansen was a Chief Scout and then Sporting Director during Andersen's time at AGF.
Andreas Hintze Rocks, Chief Scout at FC Copenhagen, said: "After a thorough recruitment process, we are very happy that with the employment of Lasse we can add a great resource to our scouting department. Lasse comes with a strong professional and technical background from many years of work as an analyst."
Andersen added: "FC Copenhagen is a unique size by Scandinavian standards. When I got the opportunity to become part of the club, I had no doubts. Now I'm looking forward to properly getting into processes and methodology, so that I can quickly contribute to strengthening FC Copenhagen of the future."
FC Copenhagen and Superliga rivals AGF both benefit from access to TransferRoom through Danish football's league-wide deal on the platform, which has allowed Denmark to grow its international transfer revenue and strengthen its position as Scandinavia's top footballing nation.
