Lecce sacked Gotti on Saturday after a poor run of results left them languishing in the relegation zone.
"The coach has signed an agreement until June 30th, 2025, with automatic renewal in the event of reaching safety," Lecce said in a statement.
Former AC Milan coach Giampaolo was most recently in charge of Sampdoria in 2022.
