The Ghanaian international made a return to the Club after signing a three-year contract.
Kwarasey joins Valerenga from Danish outfit Brondby where he made just one League appearance for the Club.
The goalkeeper had previously played for Major League Soccer side Portland Timbers as well as Roseborg also in the Norwegian top-flight.
He excused himself from Ghana’s Africa Cup of Nations qualifier with Ethiopia in order to finalize his move to Valerenga.
