01 - Preheat oven to 430°F. Place a large roasting tray inside to heat up while preparing potatoes.
02 - Place peeled and cut potatoes in a large saucepan. Cover with cold water and add 1 tablespoon salt.
03 - Bring to a boil over high heat, then reduce to simmer. Cook for 8-10 minutes until edges begin to soften but potatoes remain firm in center.
04 - Drain potatoes thoroughly in a colander and let steam dry for 2 minutes. Return to saucepan and shake vigorously to roughen the edges—this creates crispy texture.
05 - Pour hot oil or fat over potatoes in saucepan. Gently toss until evenly coated.
06 - Carefully remove hot roasting tray from oven. Transfer potatoes into tray, spreading in single layer without overcrowding. Add garlic and herbs if using.
07 - Roast for 20 minutes until beginning to turn golden.
08 - Turn potatoes and roast additional 20-25 minutes, turning once more if needed, until deeply golden brown and crispy on all sides.
09 - Season immediately with sea salt flakes and black pepper. Serve hot while crispy.
