The Italian striker has now scored in all five of his league appearances for Juventus, breaking the record of Gianluigi Buffon, who had done it five times in his career.
His last tally came in the 2015/16 season, when he scored four times in nine matches.
“It’s a great achievement, to score in all 5 of the seasons,” Del Pierro told Sky Sport Italia.
“In the last season I played for Juventus I scored in four.
It’s a fantastic achievement.
It feels good to be here and to win this title.
I know my teammates are proud of me.
I hope to help the team achieve a lot in the coming season.”
Del Pieropio had previously scored in three Serie A matches in 2015/18, but his record was broken by the Juventus striker.
The 26-year-old had started for Juventus in all three of their previous Serie A titles.
“Today was a big day for me and I want to congratulate my team-mates,” he said.
“The goal against Lazio was a fantastic opportunity and I had to do something special for the team.”
Del Perro scored his fifth Serie A goal in the 1-1 draw with Udinese last week, while he has also scored in the 2-1 victory over Genoa in the last two rounds of the league.
