At Torino, Quagliarella was an occasional starter, and with seven goals in 34 games, contributed to the club's promotion to Serie A. However, as a result of the bankruptcy of Torino Calcio, in August 2005, he was released on a free transfer and accepted a contract with Ascoli. With Ascoli, he was ensured a starting spot in the lineup during the 2005–06 season, scoring his first goal in Serie A on 21 December 2005, a 1–0 home win over Treviso.
