Roasted potatoes are a trusted staple side dish, but Exceptionally Crispy, Crackly Potatoes take things to the next level! These are hyper-charged roasted potatoes, made irresistible by two simple but powerful techniques. The first is a cornstarch “pudding”—just cornstarch and water microwaved until thick—which creates a glossy coating that delivers maximum crispiness. The second is a smart two-step cooking method all accomplished on one baking sheet: the potatoes are first covered in foil to steam until tender, then uncovered and roasted until deeply crisp and crackly. Serve alone or with aioli.
