The former Napoli man, who suffered a serious knee injury last season, has started to look like his old self again in recent weeks and has been rewarded with a new deal.
The striker still had two years to run on his previous deal with the Bianconeri but has now put pen to paper on a 12-month extension.
Quagliarella initially joined the club on loan from Napoli in Aug. 2010 and made a blistering start to his Juve career, scoring nine goals in his first 17 Serie A appearances before tearing his anterior cruciate ligament midway through the season.
However, the Old Lady still opted to sign the forward on a permanent basis that summer and although Quagliarella took a long time to rediscover his best form after returning to action this term, he has scored two goals in his last four outings.
