The Blasters qualified for the playoffs on 9 December 2014 with a 1–0 victory over Pune City.
2015 season
After the 2014 season, the club announced David James would not return to the club as the head coach and marquee player, and on 12 May 2015, it was confirmed that former England Under-20 head coach Peter Taylor would take over the manager role at the club. The club signed a new roster of foreign players, which includes Carlos Marchena as the marquee signing.
2016 season
In an effort to rebuild the team after failing to qualify for the semi-finals in the previous season, the Blasters announced the signing of Steve Coppell as their head coach on 21 June 2016. A week later, the club announced the signing of Northern Ireland international Aaron Hughes as their marquee player for the season.
2017–18 season
After losing in the previous season's finals, Steve Coppell rejected a new contract extension so the club appointed former Manchester United assistant manager René Meulensteen as their new manager. Blasters released all of their foreign players and signed some more, including former Manchester United players Dimitar Berbatov and Wes Brown. Sandesh Jhingan was appointed as the captain and the club re-signed their leading goalscorer from the first season Iain Hume.The Blasters won only one of their first eight games that season, leading to the sacking of Meulensteen. Fan-favourite manager David James returned to the squad as caretaker.The Blasters won five of the remaining ten matches and finished sixth in the 2017-18 Indian Super League season. They were eliminated in the first round of the Super Cup.
2018–19 season
Having failed to qualify for the previous season's semi-finals, the Blasters signed a three-year deal with manager David James. With a new roster, Kerala Blasters had one of their worst seasons, winning only one and drawing six of their twelve fixtures, leading to the sacking of James. This season witnessed the club's rising star Sahal Abdul Samad's emergence as Blasters' mainstay in midfield. After the international mid-season break, the Blasters appointed Nelo Vingada as their new manager for the remaining six matches. Of the remaining games, the team had only one win and three draws and finished ninth in the league. They were eliminated from the Super Cup in the tournament's qualifying round.
2019–20 season
After a disappointing season, the Blasters appointed Eelco Schattorie as their new manager, releasing all foreign players. The new roster included Raphaël Messi Bouli and Bartholomew Ogbeche as forwards. Despite early success against ATK, injuries, including Sandesh Jhingan's ACL injury and others, plagued the team throughout the season. The Blasters finished seventh in the table.
2020–21 season
From the 2020–21 season onwards, the Blasters revamped their strategy by appointing Karolis Skinkys as sporting director and Kibu Vicuña as manager. They focused on nurturing young Indian talent, extending contracts for Sahal and Rahul KP, and signing Nishu Kumar. Due to the COVID-19 pandemic, the season was held in Goa behind closed doors. Captain Sergio Cidoncha's injury setback, seven games to secure their first win, defensive struggles, and a 10th-place finish marked a challenging season. After a 4–0 loss against Hyderabad FC, Kibu Vicuna and the management mutually agreed to part ways, with Ishfaq Ahmed taking over as interim head coach for the remaining two games.
2021–22 season
After a disappointing season, Ivan Vukomanović took over as head coach in June 2021. The Blasters, participating in the Durand Cup for the first time, were knocked out in the league stage. They started the 2021–22 ISL season with a 4–2 loss to ATK Mohun Bagan but secured their first victory in 11 months against Odisha on December 5. Following an unbeaten streak of 10 games, they qualified for the playoffs for the first time since 2016. The regular season saw them break various club records, reaching the ISL finals for the third time. Unfortunately, they lost to Hyderabad in a penalty shootout, marking their third defeat in an ISL final.
2022–23 season
In April 2022, Kerala Blasters extended head coach Ivan Vukomanović's contract to 2025, a historic move for the club. Despite pre-season disruptions, the team reached the quarter-finals of the 2022 Durand Cup. Retaining only Marko Lešković and Adrián Luna, they started the ISL season impressively, winning the opening match against East Bengal FC. A controversial match against Bengaluru FC in the playoffs, marked by a disputed goal and walk-off, led to a series of disciplinary actions. The AIFF rejected Blasters' appeal, imposing fines and bans. The club also participated in the 2023 Indian Super Cup, winning the first group stage match but failing to advance after a draw with Bengaluru FC. This season ended without silverware for Kerala Blasters.
