Ingredients

• Olive or canola oil spray
• 2 potatoes, 250 g each, scrubbed clean
  (Desirees are good for chips) or 500 g sweet potato (these won't be as crispy)

Method

1. Preheat oven to 230°C.
2. Lightly spray 2 large baking trays with oil.
3. Cut potatoes into even, thin slices (about 3 mm thick).
4. Place on trays in a single layer.
5. Spray lightly with oil.
6. Bake for 25-30 minutes, until crisp and golden brown.
7. Depending on the oven, you may need to swap trays around halfway though cooking.
8. The chips may stick to the trays so lift them off using a butter knife.
9. Season with sea salt if desired.
