Zalayeta started his career with Danubio and then moving to Peñarol in Uruguay, where he made a name for himself. He moved to Juventus in 1997 but considered a promising young player at the time, he was not given much of a chance to prove himself. He spent a season on loan with Empoli, and he also starred in Uruguay's surge for the Copa América in 1999, who lost in the final to Brazil. Two more years away from the club followed, he played for Sevilla until 2001. At last when it seemed Juve lacked forwards he was brought back to Italy at the start of 2001–02, but he was loaned out to Perugia in 2004 before returning to Juventus in the same year. Although he has not played many matches thus far he has done well the times he has been given a chance.
He scored two very important extra time winners against Spanish opposition for Juventus. One came in 2003 in the quarter-finals of UEFA Champions League against FC Barcelona; the other against Real Madrid in the 2005 round of 16. In the 2003 UEFA Champions League Final, Zalayeta was one of the three Juventus players to have their penalty saved by AC Milan keeper Dida in the shootout. After a decade with Juventus, he moved to Napoli in the summer of 2007. Napoli paid €1.4million for half of the rights (co-ownership). He played 49 Serie A matches and scored 12 goals in 2 seasons, but at the start of 2009–10 season, he became surplus of the team, and not offered a shirt number.
On 17 July 2011 Zalayeta joined Uruguayan Peñarol as a free agent.
Zalayeta was selected in a 23-man squad for Uruguay's World Cup intercontinental playoff against Australia. Unfortunately it would not be a pleasant experience as Zalayeta was one out of two penalty kick takers whose shot had been saved by Australian goalkeeper Mark Schwarzer. Following Zalayeta's failure to convert, this culminated Australia to win 4–2 on penalties and qualify for the 2006 FIFA World Cup finals in Germany, and eliminating Uruguay in the process.
