During the season, Kastelic made the Ottawa Senators out of training camp and became an NHL regular. Impressed with his play, general manager Pierre Dorion signed him to a two-year $1.67 million contract on October 27, 2022. On January 13, 2023, Kastelic scored the game-winning goal in a 5β3 win over the Arizona Coyotes, playing in his hometown for the first time.
