MasterChef fans were left outraged after they saw Bondi Icebergs' Head Chef rattle the show's final four contestants in a semi-finals pressure test.
Each contestant - Ben, Khahn, Jess and Sashi - were asked to cook one dish each for thirty diners.
Ben was given an advantage for winning a previous challenge, and got the chance to choose the dish he wanted to make.
While Ben played to his strength and chose seafood, Sashi was left with pasta - a dish he was not comfortable cooking.
One-by-one, they met Bondi Icebergs Head Chef Monty Koludrovic.
Sashi was up first, and decided to make pumpkin ravioli with mushroom sauce and crispy pancetta. He struggled to find his feet in the kitchen.
He quickly fell behind and failed to make the deadline for service. Monty was breathing down Sashi's neck, yelling for him to move faster.
Fans of the show, and Sashi, took to Twitter to vent their frustration at Monty's 'bullying' behaviour.
They thought he had been treated unfairly, contrary to other episodes where judges and guest chefs had been more encouraging with the amateur cooks vying to win the reality TV series.
Some fans even accused the chef of being racist towards Sashi. Monty has taken to his personal Instagram account to defend his actions.
'I’m not sure why it seems racist? Sashi struggled with his pasta more than the other cooks struggled with their dishes tonight on @masterchefau,' he said.
'And I needed to help him get there. Not sure why you’d want to bring race into it at all...thanks for the message anyway.'
MasterChef Australia continues Sunday - Tuesday on Ten at 7.30pm.
