No, really: It's three ingredients, three steps. All you’ll need? Japanese sweet potato, honey, and brown sugar.

To begin, start by cutting a steamed Japanese sweet potato into large discs about two inches tall (eyeballing it is totally fine in this case) and lay them out on a flat sheet of aluminum foil.
Next, add a drizzle of honey over the exposed surface, and coat with a thin layer of brown sugar. The key is to spread the mixture across the surface evenly using the back of a spoon—this will help create that sought-after crunchy brulée crust.
Finally, pop the sugar-coated potatoes in the air fryer for about 15 minutes at 360 ºF, or just until the sweet mixture has fully melted. (But we'd never stop you from using your culinary torch party trick, if you so please.)
The result? A caramelized (or bruléed) coat of honey sugar that adds the perfect amount of crunchiness to complement the pillowy-soft texture of the Japanese sweet potato. Swoon.
