Amauri says he is delighted to be back at Parma, the club with whom he started his career in Serie A.
The 30-year-old striker first laid eyes on the Ennio Tardini in 2000, but never pulled on the Gialloblu shirt.
He returned in January on loan from Juventus and has proven decisive to their survival hopes.
Amauri scored both goals in Parma's 2-0 win at Udinese on Saturday.
He has already found the net seven times for his new club.
Interviewed by Sportweek, Amauri said: "I have taken returning to my first Italian club as a sign of destiny.
"From my first day here I felt the trust and the affection that I didn't feel in Turin anymore.
"Here I want to show that I am a champion, that I am not gentrified, that I am not big headed after being at Juventus."
