Preheat your oven to 400°F and line a baking sheet with parchment paper, placing a wire rack on top.
Pat the chicken wings thoroughly dry with paper towels to ensure maximum crispiness.
In a large bowl, toss the wings with sea salt, black pepper, and arrowroot powder until evenly coated.
Arrange the wings on the wire rack in a single layer and bake for 35 to 40 minutes, flipping halfway through.
While wings bake, combine honey, tamari, minced garlic, grated ginger, and sesame oil in a small saucepan over medium heat.
Simmer the sauce for 3 to 5 minutes until it thickens into a glossy glaze.
Remove wings from the oven and toss them in a large bowl with the warm honey-garlic sauce.
Garnish with sliced green onions and serve immediately.
