Preheat oven to 375°F (180°C).
Wash and dry potatoes. Cut them only ¾ of the way crosswise. To avoid slicing too far into the potato, place the spud in a large spoon and only cut until the knife hits the edge of the spoon.
Grease a baking dish. Place potatoes (cut design upwards) into pan.
Brush with melted butter and season with salt and pepper.
Bake 45 minutes, brushing twice with melted butter.
Combine grated Parmesan cheese and bread crumbs. Sprinkle on potatoes. Sprinkle on paprika.
Bake a further 20 to 30 minutes until cooked through.
