Preheat oven to 400°F and line a baking sheet with a wire rack to allow for maximum airflow.
Pat the chicken wings completely dry with paper towels to ensure the skin becomes extra crispy.
In a large bowl, toss the wings with arrowroot powder, sea salt, and black pepper until evenly coated.
Arrange the wings in a single layer on the wire rack and bake for 40 minutes, flipping them halfway through.
While the wings bake, combine honey, coconut aminos, sesame oil, minced garlic, and grated ginger in a small saucepan over medium-low heat.
Simmer the sauce for 3-5 minutes until it thickens into a glossy glaze, then remove from heat.
Transfer the hot wings to a clean bowl, pour the glaze over them, and toss until every wing is coated.
Garnish with thinly sliced green onions and serve immediately.
