1Rinse the chicken breasts, pat dry with paper towels, and cut into bite-sized pieces (about 1 inch).
2Season the chicken pieces with salt, pepper, chili flakes, onion powder, garlic powder, and oregano. Mix well and let marinate for 10 minutes.
3Prepare three bowls: one with flour, one with beaten egg, and one with Panko breadcrumbs.
4Coat each chicken piece first in flour (shake off excess), then in egg, then in breadcrumbs. For extra crunch, repeat the process (flour → egg → breadcrumbs) once more.
5Place the breaded pieces on parchment paper and let them rest while you prepare the rest.
6Preheat the air fryer to 350°F (175°C) for 5 minutes.
7Grease the air fryer basket with olive oil spray. Arrange the chicken pieces in a single layer without overlapping.
8Spray the tops with oil and cook for 5 minutes. Flip the pieces, spray again with oil, and cook for another 5 minutes until golden and crispy.
9Serve immediately with your favorite dipping sauce (BBQ, Ranch, or steak sauce).
