Step 1

Preheat the oven to 180C/350F.

Step 2

Trim the ends from the potatoes then thinly slice them into rounds (approx 3mm/1/8"). Add to a large mixing bowl with the butter and seasoning then toss until evenly coated. Add 30g / 1oz of the parmesan and give it all a gentle mix to disperse the parmesan (don't over mix or the parmesan will clump up).

Step 3

Lightly spray a 26cm/10" oven-safe pan then layer the potatoes in a circle around the outside, overlapping as needed. Make a smaller circle to fill the centre.

Step 4

Cover with foil and bake for 40 minutes. Remove the foil and increase the oven temp to 200C/400F. Sprinkle over the rest of the parmesan then bake again for around 15 minutes, or until the potatoes are crisp and fork tender. If they start charring before they're cooked through just add the foil back on and bake until fork tender.

Step 5

Serve with excess cajun butter drizzled on top then tuck in and enjoy!
