Get your chicken breasts ready. Flatten them with a meat mallet for even cooking. If you prefer smaller portions, you can slice them crosswise before tenderizing them.
Prepare breading station: Combine the all-purpose flour, garlic powder, paprika, salt, and pepper in a shallow bowl. In another container, mix the panko breadcrumbs and grated Parmesan cheese. Then, whisk an egg until smooth in a separate bowl.
Preheat your air fryer to 400°F (204°C). If your air fryer has a capacity of 4 quarts or smaller, please see the note for more info.
Bread the Chicken Breast: Dredge each chicken breast into the flour mixture, coating it on all sides. Shake off any excess flour. Then dip the flour-coated chicken breasts into the beaten egg, allowing any excess to drip off. Lastly, transfer the chicken breasts to the breadcrumb mixture, pressing gently to adhere the breadcrumbs to the chicken. Ensure the chicken breasts are evenly coated.
Air fry breaded chicken breasts for 12-15 minutes. Start by carefully placing the breaded chicken breasts in the preheated air fryer basket. Spray the top of the chicken breasts with avocado oil to help them crisp up. Flip the chicken breasts halfway and continue cooking and spray any remaining dry area. Cook until golden and crispy. Make sure the internal temperature reaches 165°F (74°C) or higher.
Once cooked, remove the chicken breasts from the air fryer and let them rest for at least 5 minutes before serving.
