Prep the chicken: Pat the chicken dry with paper towels. If using breasts, pound to an even 1/2–3/4 inch thickness so they cook evenly.
Season: In a small bowl, mix 1 teaspoon salt, 1/2 teaspoon black pepper, 1 teaspoon garlic powder, 1/2 teaspoon onion powder, 1 teaspoon Italian seasoning, and 1/2 teaspoon paprika. Rub this all over the chicken.
Make the garlic-Parmesan mix: In another bowl, combine 2 tablespoons olive oil or melted butter, 3–4 minced garlic cloves, 1/3 cup grated Parmesan, and the zest of half a lemon.
For extra crunch, stir in 1/4 cup panko.
Coat: Spoon the garlic-Parmesan mixture over the top of each piece of chicken. Press lightly so it adheres. Leave the underside uncoated so it crisps well.
Preheat the air fryer: Heat to 380°F (193°C) for 3–5 minutes.
Lightly spray the basket with nonstick spray.
Air fry: Arrange chicken in a single layer, topping side up. Air fry 10–14 minutes, depending on thickness. Do not flip.
Check doneness: Internal temperature should reach 165°F (74°C). If needed, cook 1–2 minutes more.
Finish and rest: Squeeze a little lemon juice over the chicken.
Let rest 3–5 minutes so juices settle. Sprinkle with chopped parsley.
Serve: Pair with a simple green salad, buttered noodles, or roasted broccoli. Spoon any garlicky drippings from the basket over the top.
