Preheat the air fryer to 400°F and spray the basket with non-stick cooking spray.

Cut the chicken breasts into 1-inch nuggets. Set aside.

Combine breadcrumbs, flour, garlic powder, thyme, paprika, salt, and pepper in a large bowl.

Whisk eggs in a separate bowl.

Dip chicken pieces into eggs, then coat with breadcrumb mixture.

Place coated chicken nuggets into the air fryer basket without overcrowding.

Drizzle with olive oil and cook at 400°F for 4 minutes, flip, then cook for another 1 minute.

Remove nuggets and repeat if necessary. Serve with preferred dipping sauces.
