Preheat your oven to 425°F and line a baking sheet with a wire rack to allow for maximum airflow and crispiness.
Pat the chicken wings completely dry with paper towels; removing moisture is the key to achieving a crunchy skin without deep frying.
In a large bowl, toss the wings with avocado oil, sea salt, black pepper, and arrowroot starch until every piece is lightly and evenly coated.
Arrange the wings on the wire rack in a single layer, ensuring they do not touch each other so the heat can circulate.
Bake for 35-40 minutes, flipping the wings halfway through, until the skin is deeply golden brown and the fat has rendered.
While the wings are finishing, whisk together the honey, tamari, minced garlic, grated ginger, and apple cider vinegar in a small saucepan over medium-low heat.
Simmer the sauce gently for 3-4 minutes until it reduces slightly and becomes a thick, glossy glaze.
Remove the wings from the oven and transfer them immediately to a clean bowl, pouring the warm glaze over them and tossing to coat.
Garnish with thinly sliced green onions and serve immediately while the wings are hot and the glaze is sticky.
