Preheat oven to 400°F and line a baking sheet with parchment paper.
Pat chicken wings completely dry with paper towels to ensure maximum crispiness.
In a large bowl, toss wings with arrowroot powder, sea salt, and black pepper until evenly coated.
Arrange wings on the prepared baking sheet in a single layer, leaving space between each piece.
Bake for 35-40 minutes, flipping halfway through, until the skin is golden brown and crispy.
While wings bake, whisk together honey, tamari, minced garlic, grated ginger, and sesame oil in a small saucepan over medium heat.
Simmer the sauce for 3-5 minutes until it thickens into a glossy glaze.
Remove wings from the oven and transfer to a clean bowl; pour the glaze over the hot wings and toss to coat.
Garnish with sesame seeds and sliced green onions before serving.
