Ollie later proved that he can even master dishes that some adults take their whole lives to perfect.
When Carrie shared a photo of an epic pork roast cooked by her then 11-year-old son, fans were stunned.
"He's a keeper. Took me years to master crackle!" one exclaimed.
"Well done Ollie what an awesome cooked dinner. Great job. Proud mumma I bet," noted another.
The mini MasterChef has also made his Nanna's sausage roll recipe - there's nothing like a classic!
But it's not just savoury stuff he's perfected, though!
We're drooling for his French toast loaded with ice cream and strawberries that Carrie shared back in March 2020.
"Better cook than me now!" joked the proud mum in her caption.
We may have to agree with you on that one!
After the MasterChef mac and cheese challenge this week, Carrie revealed "Chef Ollie"'s take on the classic dish and even judge Andy Allen was stunned.
"What a legend!!!!! Chef Ollie - Junior @masterchefau is calling!!!" he commented on the post.
We'll have to keep an eye out for this guy next season...
