Make sure wings have been trimmed of wing tips and cut at the joint.
In a medium bowl, whisk together maple syrup, lemon juice, ginger, onion powder, garlic powder, coconut aminos and sea salt.
Add olive oil to mixture in a thin stream while whisking to incorporate.
Divide wings into two gallon sized zip-top bags.
Pour the marinade evenly between the two bags and seal, removing all air.
Marinate the wings overnight.
Preheat oven to 250F. Prepare two rimmed cookie sheets by lining with tin foil for easy cleanup. Place stainless steel cooling racks inside the rimmed sheets.
Remove wings from the marinade and place on the racks.
Bake in the oven for 35 minutes.
Increase the oven temperature to 400F. Bake for another 40-50 minutes, checking to be sure they don’t burn.
