The first five hopefuls will try to prove to judges John Torode and Gregg Wallace that they have what it takes in tonight's opening heat.
They're given just one hour 15 minutes to cook their 'calling card' dish that represents just who they are as a cook. John and Gregg will each pick their favourite dish to go straight through, while the remaining three take on a sweet or savoury invention test.
One person will be sent home after this stage while the other four have to cook two courses to excite John and Gregg and some of the show's most inspiring winners and finalists. Who will make it through to Friday's quarter final?
MasterChef, BBC1, 8pm
