Preheat your oven to 425°F (220°C) and line a large baking sheet with parchment paper, placing a wire cooling rack on top for maximum airflow.
Thoroughly pat the chicken wings dry with paper towels to ensure the skin gets perfectly crispy during the roasting process.
In a large bowl, toss the wings with the arrowroot powder, sea salt, and black pepper until each piece is evenly coated.
Arrange the wings in a single layer on the wire rack and bake for 35 to 40 minutes, flipping halfway through, until they are golden brown and crispy.
While the wings bake, combine the honey, tamari, minced garlic, grated ginger, and sesame oil in a small saucepan over medium-low heat.
Simmer the sauce for 3 to 5 minutes until it thickens into a glossy, fragrant glaze that coats the back of a spoon.
Remove the wings from the oven and immediately toss them in a large bowl with the warm honey-garlic glaze until fully submerged.
Transfer the wings to a serving plate and garnish with toasted sesame seeds and sliced green onions for a fresh, vibrant finish.
