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 mixing bowl, toss the wings with arrowroot powder, sea salt, and black pepper until evenly coated.
Arrange the wings on the baking sheet in a single layer, making sure they are not touching each other.
Bake for 35 to 40 minutes, flipping the wings halfway through, until the skin is golden brown and very crispy.
While the wings are roasting, combine the minced garlic, honey, tamari, grated ginger, and sesame oil in a small saucepan over medium-low heat.
Simmer the sauce for 3 to 5 minutes, stirring frequently, until it thickens into a glossy glaze.
Transfer the crispy wings to a clean bowl, pour the warm glaze over them, and toss until every wing is well-coated.
Garnish with thinly sliced green onions and sesame seeds before serving immediately.
