* AuthorExistenceFailure: A few tragic examples, first with the sudden suicide of Season 2 contestant Rachel Brown, which was then followed by the death of Season 3 contestant Aaron Song from complications of diabetes, then fellow season 2 contestant Keith "K-Grease" Greene's drowning, and then Season 16 contestant Paul "Paulie" Giganti's death in April 2017.
* ExecutiveMeddling: ITV executives insisted that the show feature celebrity contestants rather than chefs looking to further their culinary careers. Ramsay wasn't happy with this change and this is the reason why he immediately jumped at the chance to work on the American version of the show - because it is much closer to his original concept.
* RealLife/MeanCharacterNiceActor: "Chef" Ramsay is the boss you have nightmares of. "Gordon" Ramsay is a professional and pleasant man. In an almost Superman-esque transformation, he can go from serene and mellow to bombastic and swearing the moment he gets his coat on and into a kitchen, as shown in ''Series/MasterChef''.
* NamesTheSame: A few contestants across all the seasons have shared names (even contestants in the same season, which causes some to be referred to by their last name), but the most notable example is that the winners of both season 4 and season 10 were named Christina.
* PromotedFanboy: All chefs who say they admire Chef Ramsay in the ConfessionCam count, but Seth from season 5 fit this so well he seemed almost like a StalkerWithoutACrush. He had memorized many details about Ramsay's private life, including the type of cars he drove, and the names of his four children.
* StupidStatementDanceMix: Ramsay's infamous rant in which he yells "''THE FUCKING BASS IS FUCKING '''RAW!'''''" has been made into a dubstep remix several times, most likely because of the hard-to-resist {{pun}} on the word "bass".
* WhatCouldHaveBeen:
** In a behind-the-scenes documentary, Josh from Season 3 revealed that he was originally going to go back into the kitchen and ask Ramsay for a second chance after his mid-service elimination. Considering how angry Ramsay already was at him, even Josh himself dreaded to think how much worse things would have gotten if Ramsay hadn't followed him out to take his jacket.
** Season 5's Ji was offered the chance to return in either Season 6 or 7, but was unavailable for the filming dates of either of those two seasons (which were filmed in close proximity). They apparently did approach her once again after that, but she had simply lost interest by that point.
** Gloria was originally supposed to stay as the red team's sous chef in Seasons 6 and 7, but either quit or was ditched at the last minute, resulting in Heather acting as a temporary replacement during Season 6, and Andi coming on-board as the permanent replacement for Season 7. It's not known exactly why this happened; some say the producers ditched Gloria because they didn't like her somewhat mopey demeanor and wanted someone [[MsFanservice younger and more attractive]], while others say Gloria quit because she wasn't comfortable with the attention she got from appearing on the show.
** Season 10 Clemenza posted on Facebook that he was approached to do ''All-Stars'', but had to decline due to health problems.
** Andi was supposed to stay on as red team sous chef for the ''All-Stars'' season, but had to withdraw when she became pregnant, leading to Christina, who had already filled in for her during Season 15 when she was getting married and going on her honeymoon, stepping in once again.
