Preheat the oven to 400°F and line a baking sheet with parchment paper or lightly grease it.

Wash the potatoes thoroughly using a brush. Do not peel.

Cut the potatoes into wedges and transfer them to a bowl of cold water. Rinse well to remove excess starch.

Add fresh cold or ice water and soak for at least 30 minutes.

Drain, rinse again, and pat the potatoes completely dry.

Add butter or oil, salt, paprika, garlic powder, black pepper, chili flakes, cornstarch, and herbs. Toss until evenly coated.

Arrange the wedges in a single layer on the baking sheet.

Bake for 30–40 minutes, flipping halfway through, until golden and crispy.

Garnish with remaining herbs and serve immediately.
