Pre-heat your oven grill/broiler. Place the bacon rashes onto an oven rack, add a drip oven tray to the bottom also to collect the excess fat. Grill at a low heat for 6-8 minutes until crispy.

Pre-heat a skillet or frying pan to a high heat, do not add any oil yet. Also, pre heat a gridle pan for the brioche burger buns or alternatively toast on top of a toaster.

Shape the beef burger patties using your hands, they should be approximately 1 inch thick. Place the burgers onto a plate. Then use your thumb and apply pressure to dent a small dip in the centre of the burgers, this ensures the burger remains flat whilst sautéing in a pan.                                                                                                    

Prepare all the burger toppings so you are ready to assemble as soon as the beef patties are ready. Lightly grill/toast the sliced brioche buns

Add a generous amount of oil to line the skillet, then immediately add in 1 or two patties maximum. The oil will be extremely hot/ Smoky so take care when doing so. Season the top side of the burgers with a pinch of salt pepper and garlic powder. Cook for 2-4 minutes on each side, add additional time for a well-done burger. Ensure to season the over side of the burger once flipped over. The burger should have a dark brown crust on either side to achieve maximum char-grilled style flavour.

Place a slice of cheese on the burger whilst the patty is still in the skillet. Now turn off the stove, the cheese will melt with the residual heat in the pan/skillet.   

Now assemble your gourmet burger stack! I like to start with the base of the grilled brioche, Ketchup, lettuce, tomatoes, onions, the burger Pattie, avocado, bacon and then top with the over half of the brioche bun.
