Special guest Jamie Oliver joins the judges as the contestants prepare for a season of secrets and surprises.

Jamie Oliver returns to present the contestants with two difficult challenges: a 15-minute meal and his mushroom and spinach rotolo.

That gold trophy is finally within reach; the Grand Finale of MasterChef.

The top three arrive to find the kitchen set up for a cook-along; the challenge represents the gateway to the semi-final, with a sizeable advantage up for grabs.

The top three enter to find the kitchen decked out for a service challenge, and there is just one cook standing between them and the final.
