Preheat oven to 425 F degrees. Line a baking sheet with parchment paper.

Pat chicken wings dry with paper towels and place them in a large bowl. Drizzle the wings with olive oil and toss well, ensuring each wing is coated.

Sprinkle the chicken wings with pepper and salt, and toss well. If using baking powder, sprinkle it all over the wings and toss again.

Arrange the wings in a single layer on the prepared baking pan. Bake for about 40 to 45 minutes or until golden and crisp.

Sprinkle with more salt and pepper if preferred and garnish with chopped parsley.
