Prepare the wings: Pat the chicken wings dry with paper towels. Combine the black pepper, smoked paprika, garlic powder, onion powder, and baking powder in a small bowl.
Season the wings: Sprinkle the seasoning mixture over the chicken and toss until evenly coated, using all of the mixture.
Air fry the wings: Arrange the wings in a single layer in the air fryer basket and drizzle with olive oil. Air fry at 400°F for 12 minutes per side, flipping halfway through. For extra crispy wings, cook for another 2–6 minutes, checking frequently. The internal temperature should reach at least 165°F.
Make the lemon pepper sauce: Stir together the melted butter, lemon juice, and lemon pepper seasoning. Taste and add sea salt if needed, especially when using salt-free lemon pepper seasoning.
Coat and serve: Toss the hot wings in the lemon pepper butter until coated. Serve immediately.
Notes
Lemon pepper seasoning: California-style lemon pepper contains salt, while my homemade lemon pepper seasoning is salt-free. Taste the butter sauce and add sea salt only if needed.
For crispy wings: Pat the chicken dry and cook in a single layer. Air fry for at least 12 minutes per side, adding a few minutes for extra crispy skin.
Sauce just before serving: Toss the hot wings with lemon pepper butter at the end to preserve their crunch.
