Khan beat four other finalists to win the competition with her chicken and potato cakes recipe at the cook off at Eckington Manor, Worcestershire.
Anne Bull, judge and former LACA Chair, said: “It’s been another great year for the McCain Simply One Pot Meal Competition and as always, it has been a joy to judge.
“The interaction between competitors has been brilliant, that’s what it’s all about, each of finalists learning from each other and exchanging recipes and tips.”
Finalist were required to create a nutritionally balanced, one pot recipe, which contained at least one product from the McCain Simply range.
As a prize for her win, Khan has received an all-expenses paid culinary trip for two to Hugh Fearnley Whittingstall’s River Cottage HQ and will showcase her winning dish at LACA.
