Begin by washing your potatoes and then pat them dry. Place each potato in between two chopsticks to use as a depth guide for making vertical slices. Transfer the potatoes to a baking tray.
In a bowl combine the olive oil, salt, pepper, cayenne pepper and herbs. Mix together well and brush onto each potato.
Pop in the oven to bake for 30 minutes at 180° or until golden brown
Garnish with some roughly chopped parsely (optional) and enjoy!
