Preheat oven to 400°F (200°C) and line a baking sheet with a wire rack for optimal airflow.
Pat the chicken wings completely dry with paper towels to ensure the skin becomes perfectly crispy.
In a large bowl, toss the wings with arrowroot powder, sea salt, and black pepper until evenly coated.
Arrange wings in a single layer on the wire rack and bake for 35-40 minutes, flipping halfway, until golden brown.
While wings bake, combine honey, tamari, minced garlic, grated ginger, and sesame oil in a small saucepan over medium-low heat.
Simmer the sauce for 4-5 minutes, stirring frequently, until it reduces into a thick, glossy glaze.
Transfer the crispy wings to a large bowl, pour the warm honey garlic glaze over them, and toss to coat thoroughly.
Garnish with thinly sliced green onions and serve immediately while hot.
