Wagyu Beef Burger with Caramelised Onions

Shape the wagyu burger mince into patties (one per person). Heat a greased medium frying pan over a medium-high heat. Add the wagyu burger patties and cook for 4-5 minutes on each side or until almost cooked through. Transfer the burger patties to an oven tray lined with baking paper and sprinkle with the Cheddar cheese. Place the parbaked sourdough burger buns beside the patties and cook for 5 minutes in the oven or until the cheese is melted.

Meanwhile, heat the olive oil in the same frying pan back over a medium heat. Add the brown onion and cook, stirring, for 5 minutes or until soft. Add the brown sugar and cook for a further 2 minutes or until caramelised.
