Hasselback Potatoes

Preheat an oven to 400 degrees F. Peel the potatoes and make slices into each one 3/4 through at very slim intervals (keeping them joined at the base).

Place the potatoes in a saucepan with water and place them over a moderate high heat. Bring the potatoes to the boil then reduce them to a simmer. Allow the potatoes to cook for 5 minutes.

Remove the potatoes from the saucepan and drain them thoroughly. Melt the butter in an oven tray with the oil. Toss the potatoes in the butter and oil and place them cut side up on the baking tray. Place the center shelf of the preheated oven and leave them to cook for 30 minutes.

Mix the breadcrumbs and Parmesan together in a bowl. Remove the potatoes from the oven and sprinkle over the Parmesan and breadcrumb mixture. Return the potatoes to the oven and leave them for a further 20 minutes until they are golden brown and cooked through. Serve hot.
