Heat the oven to 425°F and oil an oven-safe rack over a foil-lined rimmed pan. Pat wings thoroughly dry.
Mix baking powder, salt, paprika, garlic powder, onion powder, thyme, oregano, cayenne and pepper. Toss wings with their oil, then distribute the spice mixture evenly over them.
Arrange wings on the rack without touching and bake for 25 minutes. Turn each piece carefully.
Bake for 25 to 35 minutes more until crisp and at least 165°F in the thickest meat, lowering heat to 400°F if the herbs darken quickly.
Rest uncovered for 5 minutes and serve as 4 appetizer portions.
