Baroni started his career with Fiorentina, and reached his football peaks during his time at Napoli, where he played his first seasons as a Serie A regular, winning an Italian championship title (scoring the title-clinching goal on the last day of the season against Lazio) and a Supercoppa Italiana title in 1990. He left Napoli in 1991 to join Bologna, and then left the club due to its financial issues; after a short spell at Serie C2 club Poggibonsi, he then joined Serie B side Ancona, and moved to Verona in 1996, where he enjoyed his last appearances in the Italian top flight. He retired in 2000 after two seasons with hometown Serie C2 club Rondinella.
After his retired from playing football, Baroni was immediately appointed head coach of Rondinella in 2000, and then served with a handful of other Serie C2 clubs such as Montevarchi, Carrarese and F.C. Südtirol. In 2007, he was appointed as new head coach of Serie C1 club Ancona, but failed to complete his season with the biancorossi, and later accepted a youth coach offer from Serie A club Siena. During the 2008–09 season, Baroni guided the Siena Primavera (under-19) team to the Campionato Primavera final, which they eventually lost to Palermo.
On 29 October 2009 Siena appointed Baroni as new head coach in order to replace dismissed boss Marco Giampaolo. His reign as first team coach however lasted only three weeks, as he was stripped of his managerial duties on 23 November following a home defeat to Atalanta, with Alberto Malesani being appointed at his place, and Baroni being re-appointed back at his previous role of under-19 team coach.
On July 2011, he was appointed as youth team coach for Juventus. He left the role on July 2013 to become new head coach of Serie B club Virtus Lanciano. After an impressive start and a less successful end of season with the club ending in tenth place, Baroni and Virtus Lanciano mutually parted ways. He was successively named new head coach of another Serie B team, Pescara, for the 2014–15 season. After a lacklustre season, with Pescara on ninth place and one point out of the promotion playoff zone, Baroni was sacked on 16 May 2015 with one game remaining, being replaced by youth coach Massimo Oddo.
On 23 June Baroni became the head coach of Novara Calcio. He guided the club to a promotion playoff spot, but was not confirmed by the club for the new season and was successively appointed as new head coach of freshly-promoted Serie B club Benevento.
