Preheat oven to 200°C (400°F). Line a baking tray with parchment paper.
Wash and cut potatoes into wedges: Cut each potato in half lengthwise, then each half into 3–4 wedges (depending on size).
Soak in cold water for 15–30 minutes (optional, but helps remove starch and makes them crispier).
Dry thoroughly, then toss wedges in a bowl with: olive oil, garlic powder, herbs, salt, pepper, and cornflour (if using)
Spread on tray and stand each wedge up (as see in the photos). This will allow them to bake evenly.
Bake for 35–40 minutes, rotating the baking tray half-way, until golden and crispy on the edges.
