The Eredivisie season was brought to a premature close last week due to the coronavirus pandemic.
"I want to thank everyone at ADO Den Haag for the past few months," Pardew said in a club statement. "In particular the players, who gave everything on the field.
"I have positive feelings for this club and I have enjoyed the passion of the fans. I look back on a beautiful adventure in the Netherlands. It is a pity that the collaboration ends, but I wish ADO Den Haag every success in the future."
