Preheat air fryer to 400°F and spray the basket with nonstick cooking spray or lightly brush with oil.
In a wide mixing bowl, combine the breadcrumbs and parmesan cheese. Set aside.
Brush both sides of each chicken breast with aioli.
Dip the chicken in the breadcrumb mixture, pressing it into the chicken.
Spray both sides of each breast with cooking spray (optional).
Place the chicken into the basket of the air fryer, making sure to evenly space out and the chicken isn't touching.
Air fry at 400°F for 5 minutes, flip, and cook for another 5 minutes or until the chicken reaches 165°F and the crust is golden brown.
Garnish with additional parmesan cheese and chopped parsley, and serve.
Notes
Thin-sliced chicken will take less time, try 4 min/side (did not test, but these are significantly thinner).
Spread the mayo on thick so everything sticks really well.
Make sure you press the crumbs into the chicken, or else they’ll fall off.
Be sure the chicken isn’t overlapping when you put it in the air fryer. Air fryers use the circulation of air to crisp up the food, so work in batches to leave room for air flow if you need to.
I found garlic aioli with the mayo in my grocery store. We used Primal Kitchen.
