Preheat oven to 220C / 200C for fan-forced. Line 2 trays with baking paper.
Soak the chips in water for 1 hour to remove starch. Drain and pat dry on a paper towel.
Place chips in a zip-lock bag with corn flour and paprika. Shake well until evenly coated.
Single layer chips on your pre-prepared tray. Spray with oil and bake for 25-30 minutes, turning once. Season to taste.
