Preheat the air fryer to 400°F (200°C).

In a shallow bowl, mix the ground flaxseed, breadcrumbs, garlic powder, onion powder, paprika, salt, and pepper.

In another bowl, beat the egg and stir in the olive oil.

Dip each chicken breast into the egg mixture, then coat it with the flaxseed and breadcrumb mixture, pressing gently to adhere.

Place the coated chicken breasts in a single layer in the air fryer basket.

Cook at 400°F for 10 minutes. Flip the chicken breasts and cook for an additional 8 minutes or until the internal temperature reaches 165°F.

Remove from the air fryer and let rest for 5 minutes before serving.
