Preheat both sides of the Entertaining Grill to 220ºC.
Split the buns and butter the insides.
Combine the crushed garlic with the mayonnaise.
Put the ground beef in a mixing bowl. Evenly sprinkle over the salt and pepper. Fold the meat over a few times to incorporate everything. Do not overwork the mixture.
Divide the mixture into 4 and place on a baking tray lined with baking parchment. Gently form each portion into a burger by pressing the mixture down until they are about 2cm thick and slightly wider than your bun.
Oil the grill plate and place the burgers on. Allow the burger to sear until browned. Turn and sear the other side. Once evenly browned turn the temperature down to 200ºC and cook for approximately 5 minutes on each side.
Whilst the burgers are cooking, Grill the brioche buns, butter side down until browned.
Allow the burgers to rest for a few minutes.
Assemble your burgers by layering the ingredients on your brioche bun.
