Preheat your air fryer to 400°F (200°C) for about 5 minutes.

Lightly season both sides of your sliced chicken breasts with salt and pepper.

In a shallow bowl, combine panko breadcrumbs, grated parmesan cheese, dried oregano, and garlic powder. Mix them well.

In another bowl, crack an egg and whisk it until well combined.

Dip each seasoned chicken breast into the whisked egg, allowing any excess to drip off, then press into the breadcrumb mixture.

Lightly spray the air fryer basket with olive oil or cooking spray. Arrange the coated chicken breasts in the basket.

Air fry the chicken at 400°F (200°C) for 10-12 minutes, flipping halfway through.

Once cooked, remove the chicken from the air fryer and let it rest for a few minutes.

Slice the chicken and serve warm with a salad or your favorite dipping sauce.
