Preheat your oven to 400°F and line a large baking sheet with parchment paper.
Pat the chicken wings thoroughly dry with paper towels to ensure the skin gets maximum crispiness.
In a large bowl, toss the wings with arrowroot powder, sea salt, and black pepper until each wing is evenly coated.
Arrange the wings on the prepared baking sheet in a single layer and bake for 35-40 minutes, flipping halfway through, until golden brown.
While the wings are roasting, combine the honey, tamari, minced garlic, grated ginger, and sesame oil in a small saucepan over medium heat.
Simmer the sauce for 3-5 minutes, stirring frequently, until it thickens into a glossy, sticky glaze.
Once the wings are finished, transfer them to a clean bowl, pour the warm glaze over them, and toss to coat every wing.
Garnish with sesame seeds and sliced green onions before serving immediately.
