Preheat your oven to 400°F (200°C) and place a wire cooling rack over a large rimmed baking sheet lined with parchment paper.
Pat the chicken wings thoroughly 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 to 40 minutes, flipping halfway through, until the skin is golden brown and crispy.
While the wings bake, combine the honey, coconut aminos, sesame oil, minced garlic, and grated ginger in a small saucepan over medium-low heat.
Simmer the sauce for 3 to 5 minutes until it thickens into a syrupy consistency, then remove from heat.
Transfer the hot, crispy wings to a clean bowl, pour the honey-garlic glaze over them, and toss until every wing is well-coated.
Garnish with thinly sliced green onions and serve immediately.
