The BBC comedy ran from 1998-2000 and has also aired a number of special episodes.
Creators Craig Cash and Caroline Aherne, who starred as Dave and Denise, have now agreed to discuss the show in The Royle Family: Behind The Sofa.
The one-off programme, with a voiceover from Mark Radcliffe, will feature interviews with cast members Liz Smith, Sue Johnston, Ricky Tomlinson, Ralf Little, Jessica Hynes, Sheridan Smith and Geoffrey Hughes.
Writer Phil Mealey will also contribute to the show along with celebrity fans Catherine Tate, Paul Whitehouse, Willy Russell, Jimmy McGovern and Henry Normal. Meanwhile, the soundtrack will be provided by a brass band who will perform a number of Oasis tracks.
GOLD will also air The Royle Family Portraits, in which Cash, Aherne and some celebrity fans choose their favourite moments from the show.
UKTV's director of commissioning Jane Rogerson said: "It's breathtaking to see Craig, Caroline and the whole Royle family cast talking so warmly, openly and funnily about the series and their relationships. It's a genuine heartwarming treat for the viewer and we're just really appreciative of the love and care they have put into this for us."
The Royle Family: Behind The Sofa will air on Wednesday, November 10 at 9pm while The Royle Family Portraits will be broadcast on November 17 at 9pm.
