Preheat the oven to 450 degrees. Place your baking rack near the top part of the oven. Line a baking sheet with foil, then coat it with cooking spray.
Trim the chicken wings. If you need help, view the beginning of this video for simple instructions.
Once you have trimmed the wings, place them on the baking sheet. Drizzle the wings with a bit of olive oil, to taste, then season both sides with sea salt and freshly cracked pepper, to taste. Toss to coat the wings evenly.
Spread the wings out on the baking sheet, skin side up, and place them into the oven to bake for 30 minutes.
Flip the chicken after 30 minutes, then continue baking for another 15-20 minutes, or until the chicken is crispy and cooked through.
