Belotti is nicknamed Il Gallo (The Rooster). The nickname comes from the surname of his close childhood friend, who jokingly suggested he celebrate his goals by mimicking a rooster's comb with an open hand to his forehead.
He took his first steps as a footballer in the oratory school of Gorlago, and with Grumellese. After an unsuccessful trial with Atalanta, he was signed by AlbinoLeffe and went through their youth system.

He also scored 13 goals as team top-scorer for the youth team throughout the 2011–12 season, winning a youth title, the Trofeo Dossena, in June 2012.
The following season, he was fully promoted to the first team, and made 31 appearances in Lega Pro Prima Divisione, scoring 12 goals. He also made an appearance during the 2012–13 Coppa Italia. Given the presence in the squad of the defender Mauro Belotti, Andrea was nicknamed Belottino.
On 2 September 2013, he was loaned for a fee of €500,000 (with a buyout clause set at €2.5 million) to Palermo in Serie B. He made his debut with the Sicilians on 24 September 2013, as a substitute for Davide Di Gennaro in a game against Bari, and provided an assist to Kyle Lafferty in a 1–2 loss. He scored his first goal for the Rosaneri on 5 October against Brescia. On 3 May 2014, he was promoted to Serie A after a 1–0 win away to Novara.

He played in 38 games throughout the season, largely as a substitute, in which he scored six goals.
On 18 August 2015, he was officially signed by Torino for a reported fee of €7.5 million. He scored his first goal in Serie A for the Granata in a 2–0 win against Bologna. On 16 January 2016, he scored his first brace for Torino in a 4–2 win over Frosinone. On 20 March, Belotti scored from the penalty spot in the 48th minute to halt Juventus goalkeeper Gianluigi Buffon's record of longest consecutive minutes not conceded in a 4–1 home defeat. On 3 April, he scored a decisive penalty that allowed Torino to comeback and defeat Inter, 2–1, at the Stadio Meazza. He scored eleven goals in the second half of the 2015–16 season, and concluded the season with 12 goals in 35 appearances.
Belotti began the 2016–17 season scoring a goal against Milan at the San Siro, but had a penalty saved by Gianluigi Donnarumma in a 3–2 defeat. The following round, on 28 August 2016, he scored his first career hat-trick in a 5–1 home win against Bologna in Serie A, despite later missing an injury-time penalty during the game. On 25 September he opened the score in a 3–1 victory over Roma; he would also win a penalty after being fouled by former teammate Bruno Peres, and assist Iago Falque for Torino's third goal. On 4 December he extended his contract with Torino until 2021, with a €100 million release clause valid only to foreign clubs. On 5 March 2017, he wore the captain's armband for the first time against Palermo, in which he scored the fastest hat-trick in Serie A since 30 January 2000 (seven minutes and 15 seconds), surpassing the previous record belonging to the Ukrainian Andriy Shevchenko. The following month, he became the first player under the age of 24 to score 24 goals in a single Serie A season since Shevchenko in 1999–00. He ended the season with 26 league goals and two in Coppa Italia.
Belotti received his first call-up to the Italy under-19 in December 2011 against the Lega Pro representatives squad; scoring a goal in the match, won 4–2. In the 2012 UEFA European Under-19 Football Championship elite qualification round he featured as Italy's centre-forward in the 4–2–3–1 formation, scoring once in three appearances.

Under manager Luigi Di Biagio, Belotti took part in the 2015 UEFA European Under-21 Championship in the Czech Republic, scoring the opening goal in a 3–1 defeat of England in Italy's final group match, although the result was not enough to see the Italian under-21 side progress to the semi-finals, as the azzurrini finished third in their group, behind the two eventual finalists Portugal and Sweden.
On 27 August 2016, Belotti was called up to the senior squad for the first time by Gian Piero Ventura for a friendly against France on 1 September and a 2018 World Cup qualification match on 5 September against Israel. He made his senior international debut in the friendly against France, coming on as a substitute in a 3–1 home loss. Belotti scored his first senior goal on 9 October, the opening goal of their third World Cup qualification match, a 3–2 away victory to Macedonia.
He began his career as a midfielder and winger, but under the guidance of Albinoleffe's youth coach Alessio Pala, he adapted to a forward. Compared to Gianluca Vialli for his athleticism and style of play, Belotti is a prolific striker, and has a strong shot with both feet. He is strong in aerial duels, and stands out for his acceleration, tactical intelligence, work-rate and eye for goal.
