In June 2021, Globo announced that Fausto Silva had left the network, and that his long-running variety show Domingão do Faustão would be replaced by a new program hosted by Luciano Huck, who had hosted the Saturday-afternoon variety show Caldeirão do Huck.
[3][4] However, after strong ratings performance and critical reception, in October 2021 Mion was named the full-time host.
[5][6] The show underwent a refresh in March 2022, including officially being re-titled Caldeirão com Mion, adding new mascot characters as assistants (a panda and Globinho), as well as the new segment Caldeirola.
[11] Mion's performance as host was widely praised on social media, with viewers commenting upon his energy and happiness on-air, and considering the program to be improved over Huck's tenure.
[14] Its viewership remained steady in the months that followed, usually averaging around 13 points or higher in Greater São Paulo, and beating all other programs in its timeslot.
