MasterChef Thailand (season 5) is the fifth season of the Thai version of the competitive reality TV series MasterChef. The show premiered on Channel 7 on February 13, 2022. Pasan Svastivatana [th], Kwantip Devakula [th] and Pongtawat Chalermkittichai all returned as judges in this season. Piyathida Mittiraroch [th] also returned as the host.
 Applications for contestants of the fifth season were opened on October 6, 2021, ending at October 31, 2021, with one of the additional requirements being that auditionees must not have more than 3 months worth of cookery education (courses in individual dishes are still allowed)
 Sixty successful home cooks arrived at the MasterChef Audition Stadium, loosely built based on the Netflix show, Squid Game. The home cooks were informed that if their aprons are snatched, their journey of receiving a white apron would be over.
 Thirty out of sixty home cooks advanced to the next round. Before the second round, the remaining home cooks were asked to pick a coloured station (red, yellow and green), each with a corresponding dish that they have to make.
 Twelve out of thirty home cooks (Angkrit, Arth, Dang, Jake, Joe, Kaowtip, Maam, Medploy, Moo, Roen, Ten, and Tueng) passed the auditions and got their white aprons.
 Twenty-four out of the forty-eight already-eliminated home cooks were invited back for another chance to win the white apron.
 The teams for the team challenge were as follows:
 During the challenge, Nhong was switched with Brad as the team captain after numerous mistakes involving his role. After the first 2 hours, the light blue team did not complete 10 main dishes, while the pink team did not complete 16 dishes, meaning that those dishes are not served. The pink team won the challenge with a 29-21 score.
 Despite pink team's win, due to their mediocre performance and criticism from the food critics, there were only 7 white aprons available to them. They decided that Holly, Mai Zung, Michel, Nu, Tas, Ton, and Yok would receive the aprons. The episode left on a cliffhanger, with the remaining five members from the pink team and all of the light blue team members given their last chance to win the white apron.
 The light blue team, who lost the previous team challenge from the last episode joined the five unselected pink team members for their last chance to win the white apron.
 Out of the seventeen home cooks, only eight were able to win their white aprons, including, Brad, Aim, Belle, Kwan, Naan, Nhong, Oat and Yup. Two weeks later, the contestants entered the MasterChef Kitchen for the first time. However, only twenty-two of them were present, as five of the contestants, Jake, Maam, Moo, Roen and Ten, have to be isolated due to them being in the risk group of getting COVID-19 as a precaution. As a result, those five people are automatically eliminated and will not move on to the next round.
 After the time is up, the judges determined the 7 people whose dishes were not up to standard. They were Aim, Joe, Kwan, Medploy, Oat, Tas, and Ton. Angkrit, Brad, and Nu were deemed as the top three dishes. Nu won the overall challenge.
 With Nu being the winner of the black box challenge, he is eligible to save 2 people out of the seven people whose dishes are the worst. He chose Kwan and Ton, despite the fact that those two dishes contain a raw component. Judges later decided that only three people would be eliminated from this challenge. They were Aim, Joe and Medploy.
 Before the challenge was officially announced, the judges introduced Chef Tukta, a chef in The Next Iron Chef Thailand chef, who was a home cook at the beginning of her cooking career. She is the owner of Krua Baan Yee Sarn (Yeesarn Kitchen), a restaurant with dishes from Thai original cuisine.
 Oat was declared as the winner of this challenge, with Tueng and Yup being the runners-up. Oat was given immunity from the next invention test as well as an ability to choose eight other people to join him. He chose Dang, Holly, Kaowtip, Nant, Tas, Tueng, and Yup.
 Kwan, Nu, Yok and Ton were named as four of the worst dishes in this challenge. Nu and Yok were saved as their dishes are deemed innovative and creative by the judges, but lack taste and embrace of the main ingredient. Ton was eliminated from this challenge.
