The Big Family Cooking Showdown, often referred to as simply Cooking Showdown or BFCS, is a BBC team cooking competition. The first season was hosted by Great British Bake Off winner Nadiya Hussain and Zoe Ball. Each week, two teams of three family members competed in three challenges, judged by Michelin starred chef Giorgio Locatelli and cookery teacher Rosemary Shrager. The winners in each of eight heats moved on to the semi-finals, consisting of three episodes. The three semi-final winners then progressed to the final episode where the winning family was selected. The Big Family Cooking Showdown premiered on BBC Two on Tuesday, 15 August 2017, then moved to Thursday evenings on 31 August to avoid a scheduling conflict with The Great British Bake Off on Channel 4.

On 9 May 2018, the BBC announced that the show would return for a second season of 14 episodes airing in a new slot of 7pm. The second season aired multiple episodes per week, beginning on 15 October 2018. The show returned with a refreshed style and modified format, and without any of the original line-up of presenters or judges featured in the first series. Presenter and Celebrity MasterChef winner Angellica Bell was joined by Michelin starred chef Tommy Banks to host and co-judge the second series. After viewership and ratings fell below expectations, BBC announced that the show would be cancelled.
