Preheat your oven to 400°F (200°C) and place a wire rack over a large baking sheet.
Pat the chicken wings completely dry with paper towels to ensure maximum crispiness.
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 35-40 minutes, flipping halfway through, until golden and crispy.
While the wings bake, whisk together the honey, tamari, toasted sesame oil, minced garlic, and grated ginger in a small saucepan.
Simmer the sauce over medium-low heat for 3-5 minutes until it thickens into a glossy glaze.
Transfer the hot, crispy wings to a clean bowl, pour the honey-garlic glaze over them, and toss to coat thoroughly.
Garnish with thinly sliced green onions and serve immediately.
