To a small bowl, whisk together the soy sauce, Swerve brown sugar substitute (or regular brown sugar if don't want to keep this recipe keto), ginger paste, garlic powder, onion powder, and black pepper.
Pour the marinade into a zip top bag and add the chicken. Seal the bag then toss to coat well.
Let the chicken marinate in the fridge for at least one hour, but up to overnight.
Preheat your air fryer to 350 degrees.
Cook the chicken on a rack in the air fryer for 20-25 minutes until nicely browned and cooked through.
Let rest in the air fryer with the heat off for a few minutes.
Garish with chopped green onions and sesame seeds before serving.
You can use low sodium soy sauce or replace it with coconut aminos.If you're not watching your carbs, you can use regular brown sugar instead of Swerve.
