Begin by preheating your air fryer to 390°F (199°C). This is an important step, as it ensures that your chicken cooks evenly and achieves that lovely crisp texture.

Take your two large boneless chicken breasts and slice them horizontally, creating four fillets. Place each fillet on a cutting board and cover it with plastic wrap. Using a rolling pin or meat tenderizer, gently pound the chicken until it’s an even thickness. This step helps in cooking the chicken evenly and keeping it juicy.

In a small mixing bowl, combine 1/4 cup of mayonnaise with two minced garlic cloves, onion powder, Italian seasoning, and optional garlic powder. Add salt to taste, and for a refreshing twist, consider mixing in a tablespoon of lemon juice. This adds a lovely brightness to the dish. Mix it all well until you have a smooth, creamy blend.

Spread the garlic mayo mixture generously over each fillet, ensuring they are well-coated. This mayo will not just create flavor but also help the cheese mixture stick beautifully.

In another shallow bowl, mix together your grated Parmesan cheese and panko breadcrumbs. If you’re adding an optional touch of smoky flavor, toss in some smoked paprika. This combination will add a crispy, cheesy coating that’s out of this world.

Take each fillet and dredge it in the Parmesan and breadcrumb mixture. Make sure to press down lightly on the coating with your tongs to get it to stick. After coating one side, flip it over and repeat, ensuring you shake off any excess.

Place the coated chicken fillets in the basket of your air fryer, making sure they are arranged in a single layer for even cooking. Cook for 10-12 minutes, or until they turn golden brown. Midway through, about 5-6 minutes in, pause the cooking and carefully flip the chicken over using tongs to ensure both sides get that delicious crisp.

Once the internal temperature reaches 165°F, remove the chicken and let it rest for a minute. Garnish with fresh parsley or oregano leaves. Serve it hot and enjoy the delightful crispy chicken as a part of your meal!
