01 - Preheat oven to 430°F. Place large roasting tray inside to heat up thoroughly.
02 - Place peeled and cut potatoes in large saucepan. Cover with cold water and add 1 tbsp salt.
03 - Bring to boil, then simmer 8–10 minutes until edges begin to soften but potatoes remain firm in center.
04 - Drain well and let steam dry for 2 minutes. Return to pan and shake gently to roughen edges for crispiness.
05 - Carefully pour hot oil or fat over potatoes, tossing to coat evenly.
06 - Remove hot tray from oven. Tip potatoes into tray, spreading in single layer. Add garlic and herbs if using.
07 - Roast 20 minutes, turn potatoes. Roast additional 20–25 minutes, turning once if needed, until golden brown and crispy.
08 - Season with sea salt flakes and black pepper. Serve immediately while hot.
