Preheat the oven to 400 degrees F. Line a sheet pan with foil and place an oven safe rack on top of the foil. Coat the rack with cooking spray.
Place the chicken wings in a large bowl along with the oil. Toss to coat evenly.
Add the spice rub to the bowl. Toss the wings with the spice rub until they're coated.
Arrange the chicken wings in a single layer on the rack.
Bake for 45 minutes or until crispy and golden brown. Top with parsley, then serve.
I highly recommend using homemade barbecue rub. It takes just minutes to put together, and can be used in so many different ways. If you don't have enough time to make your own rub, feel free to use your favorite store bought spice blend.
To save time, look for "party style" wings which have the wingettes and the drummettes already separated.
