It's waste week, and things are heating up in the hub, where the cooks are set their toughest Level Up yet. They have to level up the basic meal deal and create not one, but three epic elements to wow the judges.

For the service challenge, the cooks are tasked with creating a menu based entirely on leftovers from the hub, and the theme of the menu is bowl food. They are introduced to guest judge award-winning chef Ramael Scully, who specialises in the creative use of food waste. This week's prize is to spend a week working with Scully in his restaurant.

The week ends in another nail-biting Knives Out challenge, after which one more cook exits the contest, leaving just seven to battle it out next time.

It's halfway through the contest and with only six cooks remaining, it's getting hot in the kitchen.

In the Level Up, the cooks must transform basic tinned food into a bougie brunch that blows the mentors' socks off.

This week's Service Challenge is pasta, but with a twist. There's only one rule – no traditional Italian dishes allowed! Guest judge Nathan Smith has had huge viral hits with some of his mash-up ideas, and the cook who most impresses in the restaurant kitchen will win a live cook-along with Nathan in front of all his followers.

For this week's nail-biting Knives Out challenge, the bottom two cooks must make churros with salted caramel sauce. And when one cook is sent home, just five cooks remain.
