In a large mixing bowl, combine the chicken wings, baking powder, and flour. Toss until the chicken is thoroughly coated and set aside for 20 minutes.
Preheat the oven to 425°F and line a rimmed baking sheet with aluminum foil. Place a wire rack over the baking sheet.
Drizzle the olive oil over the chicken wings and add the lemon pepper, garlic powder, onion powder, and 1 tablespoon of lemon zest. Toss until the chicken is thoroughly coated in olive oil and seasoning.
Arrange the chicken wings in a single layer (with some space between each) on the wire rack. Bake for 20 minutes, flip, and repeat until the wings are cooked through and crispy golden brown. This should take 45 minutes to 1 hour total.
Just before the chicken comes out of the oven, whisk together the melted butter, lemon juice, parsley, and the remaining lemon zest in a large mixing bowl.
Toss the chicken wings with the lemon butter sauce and serve ASAP.
Notes
Place any leftover lemon pepper wings in an airtight container and store them in the refrigerator for up to 4 days. For maximum crispiness, I recommend reheating them in a 375ºF oven or air fryer until they’re heated through.
