Heat the oven to 200C/180C fan/gas 6. Place the bacon on a rack over a baking sheet. Cook for 10 mins until starting to turn crispy, then remove and brush with maple syrup on both sides. Cook for a further 2–3 mins, or until cooked to your liking.
Fry your eggs and place 1 on the base of each toasted brioche bun. Top with the glazed bacon, a dollop of ketchup and the lid of the bun.
