Pour the wings into a large bowl and season liberally with salt and the lemon pepper spice blend.
Spray the air fryer basket with non-stick cooking spray.
Arrange the chicken wings in a single layer in the air fryer, and cook for 12 minutes. You may need to work in batches.
Flip and cook for 3 minutes longer, until the wings reach 175 degrees F, with a digital meat thermometer.
Meanwhile, melt the butter in a small saucepan over low heat.
Add the garlic to the butter and 1/2 teaspoon of fresh lemon zest.
When the wings are finished cooking, toss them in a clean bowl and drizzle the garlic butter over them, mixing to coat.
Serve immediately with sliced celery, blue cheese, or ranch dressing.
Notes
Avoiding Burnt Spices: Since pepper can burn at high temperatures, adding the lemon pepper seasoning before cooking helps it meld into the skin without charring.
Air Fryer Adjustment: Air fryer temperatures can vary with different makes and models. If you find the wings are cooking too quickly, adjust the temperature down to 375°F to prevent burning.
