Zárate began his club football career at Vélez Sarsfield where he had played since childhood. At age 17, considered too strong for the youth category, he was promoted to the first team with which he made his full debut on 21 April 2004 against Arsenal de Sarandí.

Zárate started his career with Vélez Sarsfield in his native country, playing three years for the team and winning the Primera División title in the 2005 Clausura tournament. He later signed for Qatari side Al-Sadd in 2007, where he played only six months before transferring on loan to Birmingham City in England.

After a loan at Inter Milan and a brief return to Vélez Sarsfield, he joined West Ham United in 2014, spending the second half of his first season on loan at Queens Park Rangers. In January 2016, Zárate joined Italian club Fiorentina. A year later, he returned to England, joining Watford on a two-and-a-half-year, £2.3 million deal.
