Preheat your oven to 425°F and line a large rimmed baking sheet with parchment paper for easy cleanup.
Pat the chicken wings thoroughly dry with paper towels; removing all surface moisture is the secret to achieving a crispy skin without deep-frying.
In a large mixing bowl, toss the wings with arrowroot powder, sea salt, and black pepper until each piece is lightly and evenly coated.
Arrange the wings on the prepared baking sheet in a single layer, ensuring they do not touch to allow for proper air circulation and even browning.
Bake for 35 to 40 minutes, turning the wings over halfway through, until they are deeply golden and the skin is crackling.
While the wings are roasting, combine the honey, tamari, toasted sesame oil, minced garlic, grated ginger, and rice vinegar in a small saucepan over medium-low heat.
Simmer the sauce for 3 to 5 minutes, stirring occasionally, until it reduces slightly and becomes a thick, glossy glaze.
Transfer the hot, crispy wings to a clean bowl, pour the warm glaze over them, and toss until every wing is perfectly coated.
Plate the wings immediately and garnish with sesame seeds and sliced green onions for a fresh, colorful finish.
