Preheat your oven to 400°F (200°C) and line a baking sheet with a wire rack for optimal air circulation.
Pat the chicken wings completely dry with paper towels to ensure the skin becomes crispy during roasting.
In a large mixing bowl, toss the wings with arrowroot starch, sea salt, and black pepper until each piece is lightly and evenly coated.
Arrange the wings in a single layer on the wire rack and bake for 35-40 minutes, flipping halfway through, until golden brown.
While the wings are roasting, combine the honey, coconut aminos, sesame oil, minced garlic, and grated ginger in a small saucepan.
Simmer the sauce over medium-low heat for 3-5 minutes, whisking occasionally, until it reduces into a thick, glossy glaze.
Remove the crispy wings from the oven and transfer them to a clean bowl; pour the warm honey-garlic glaze over them and toss well.
Transfer to a plate and garnish with thinly sliced green onions before serving immediately.
