In another medium bowl combine breadcrumbs and grated Parmesan.
1/2 cup Italian seasoned breadcrumbs, 1/4 cup grated Parmesan
Pat the chicken dry with a paper towel.
1 lb boneless skinless chicken breasts
Use a sharp knife and slice horizontally into one side of the chicken and cut through to the other side. You want four total chicken fillets for this recipe, so depending on the size of your chicken, you may be using two chicken breasts.
Place two chicken fillets between two pieces of plastic wrap or parchment and pound to flatten using a mallet or rolling pin. Repeat with the other 2 fillets.
Sprinkle the garlic powder/salt mixture evenly over both sides of all 4 fillets.
Place a piece of ham and then a piece of Swiss cheese on each filet. Fold them in half from top to bottom and not side to side.
4 slices ham, 4 slices Swiss cheese
Dredge each "packet" of chicken in all-purpose flour, then the egg mixture, and finally the breadcrumb mixture, making sure to coat all sides. Repeat with the other 3 pieces of rolled chicken.
Preheat air fryer to 370F for 3 minutes.
Coat all sides of the chicken evenly with olive oil spray. Secure ends with 2-3 toothpicks. Let sit for 3-5 minutes.
2 tbsp olive oil (spray)
Brush olive oil in the air fryer basket or use air fryer parchment. Position chicken in the basket so that they aren't touching.
Bake at 370F for 10 minutes and then carefully flip and cook for another 3-4 minutes or until chicken reaches 165F using a meat thermometer.
Let rest for 5 minutes.
Making the Parmesan Sauce
In medium saucepan melt the butter over medium-low heat.
2 tbsp unsalted butter
Sprinkle in flour and then whisk gently for ~3 minutes or until the flour and butter have taken on a caramel color.
2 tbsp all-purpose flour
Slowly pour in the warmed milk, chicken stock, and garlic powder, whisking constantly. Cook for 1 minute.
1 cup whole milk, warmed, 1/4 cup chicken stock, 1/2 tsp garlic powder
Add the Parmesan and stir gently until melted.
3/4 cup shredded Parmesan
Add Dijon, turn the heat down to low, and simmer until thickened, ~3 minutes, stirring occasionally.
2 tbsp Dijon mustard, Salt & pepper to taste
Drizzle over the chicken.
Notes
For the Parmesan that is mixed with breadcrumbs, you’ll want to use finely grated cheese. Yes, you can use the stuff in the green can if needed.
For the Parmesan sauce, you’ll want to use grated/shredded cheese. Nothing powdered for the sauce!
This recipe calls for Swiss cheese, but provolone is absolutely fantastic as well.
