Step 1: Preheat oven to 200C (180C fan forced).
Step 2: Line a large baking tray with baking paper.
Step 3: To make each potato sit flat, trim and piece from each (to allow it to sit flat) and using a small sharp knife, cut thin slits in top of potatoes at 3mm intervals, being careful not to cut all the way through (I put a wooden spoon either side of the potato to prevent this happening).
Step 4: Place the potatoes, cut side up, on prepared tray and brush with oil and sprinkle with salt, sage and parmesan and bake for 1 hour or until golden and tender.
