* AllStarCast: Season 8 -- ''Top Chef: All-Stars'', which brought back 18 chefs across all seven seasons for one more shot at the title.
* HeyItsThatGuy: Chef Nyesha Arrington from the Texas season won her current job as Wilshire's executive chef on Food Network's Chef Hunter.
** Before competing in their respective seasons, Ed Cotton (Season 7) and Richard Blais (Season 4 and 8) both served as sous chefs to [[IronChefAmerica Iron Chef]] Cat Cora. Ashley (Season 6) has been serving as sous chef for [[IronChefAmerica Iron Chef]] Alex Guarnaschelli.
* OpinionMyopia / FanMyopia - Fans get extremely attached to their chefs - they're the best in the competition/cook the food they'd most want to eat. As such, the competition slides through only because of ratings stunts or producer brain fail. This trope is common to all reality shows, but shines brightly here as Top Chef is a cooking show, and none of the fans have ever or will ever eat the food prepared for competition.
* ThePeteBest: Katie Lee was the hostess of season one of Top Chef before being replaced by Padma Lakshmi. Katie was brought back as a guest judge in ''All-Stars''.
** Kelly Choi hosted the first two seasons of ''Masters'' before being replaced by Curtis Stone, who is incidentally the first male host of any of the shows.
** For Top Chef Canada, Season 1 hostess Thea Andrews was replaced for season 2 by Canadian actress and former model, Lisa Ray. Though in this case, it was because Thea was pregnant, as shown when she guest hosted for the third episode of season two.
