Preheat oven to 400 degrees and Spread Panko bread crumbs on a baking sheet. Toast for 5 minutes, or until lightly browned. Remove and cool, transfer to a plate.Pro Tip: I don't recommend toasting the bread crumbs in the air fryer. The circulating hot hair will send them flying everywhere, as they are so delicate and light! 1½ cup Panko bread crumbs
Slice each chicken breast in half horizontally so that you get two chicken fillets from each breast.
1 lb chicken breasts
Add the flour and seasonings to the cooled toasted Panko bread crumbs, and mix together.
3 tablespoon flour, 1 teaspoon garlic powder, 1 teaspoon salt, ½ teaspoon black pepper, 2 tablespoon parsley
Whisk together the egg and Dijon mustard in a medium mixing bowl to blend.
2 large eggs, 3 tablespoon Dijon mustard
Dip each chicken breast fillet in the bowl of whisked egg and Dijon mustard, turning to coat both sides of the chicken breast fillets.
Dredge the egg and mustard coated chicken breast fillets in the Panko and seasoned flour mixture, making sure the Panko mixture adheres to the chicken.
Use a pair of tongs to turn each chicken breast fillet so that both sides are evenly coated.
Place the Panko crusted chicken breast fillets in the air fryer basket with space between chicken portions. Air fry at 375 F for 5 minutes. PRO TIP: If you are concerned about the chicken sticking, use a little vegetable oil with an Oil Sprayer. Don't use non stick cooking spray, the propellants can damage the cooking elements of the air fryer. Flip the chicken pieces and cook for another 5-7 minutes, or until golden brown. Use a ThermoPro or any instant read thermometer to verify the thickest part of the chicken breast fillets is 165F.
