In July, Åsen played both games against SJK in the second qualifying round of the UEFA Conference League.

In September 2024, after Lillestrøm had hired their new coach David Nielsen, Åsen was stripped of being captain, in favour of Ruben Gabrielsen. Åsen told the media that it was not unexpected as things changed in football, and that it had been an honour to perform the role of captain as long as he had. Only months later, after poor results throughout the season, Lillestrøm was relegated to the Norwegian First Division, Åsen's first time back in the league since playing for Ranheim. In the final game of the 2025 season Åsen was an unused substitute in the 2025 Norwegian Cup final, where Lillestrøm won their seventh cup title.
