It’s Mystery Box day, and upon arrival, our home cooks are greeted by an enormous Mystery Box, the biggest ever in MasterChef history, marking the start of Big Week.

Contestants have 45 minutes on Day 1 to prepare elements of their dish and leave them overnight for 14 hours. They then have 60 minutes on Day 2 to finish their dish.

For the challenge contestants will have 75 minutes to create a dish using at least one of the cereals from today’s Mystery Box.

Today’s two-round Immunity challenge sees the winning team from yesterday’s team challenge join Malissa to battle it out for immunity.

Contestants arrive at the MasterChef kitchen to discover the space transformed into a restaurant.

In Round One, Jamie Oliver tasks the contestants with making a delicious 15 Minute Meal.
