Butterfly the chicken: Using a sharp knife, butterfly the chicken breast. To do this, lay the chicken breast on a flat surface. Make a cut in the side of the chicken, horizontally. Stop short of cutting all the way through. Open the chicken breast like a book, and repeat for the second breast.
2 Chicken breasts
Pound the chicken: Cover the chicken breasts with plastic wrap or parchment paper, and pound flat with a meat mallet or a heavy skillet/rolling pin.
Season the chicken: Mix together all the spices. Sprinkle the seasoning onto both sides of the chicken breast liberally, and rub in.
1 teaspoon Garlic Powder, 1 teaspoon Onion powder, 1 teaspoon Smoked paprika, Salt and Pepper
Stuff and roll: Lay down two slices of ham, and equal parts of the cheese onto the butterflied chicken breast. Roll the chicken tightly, folding the cheese into the roll. Close the seam with three toothpicks, going through the seam.
4 slices Black forest ham, ½ cup Swiss cheese
Bread the chicken: Brush the top of the rolled chicken breasts with dijon mustard. Next, place the chicken rolls in the breadcrumbs in a shallow dish. Brush the other side of the chicken with more mustard, and ensure the chicken rolls are coated evenly with the breadcrumbs.
2 tablespoon Dijon mustard, ¼ cup Panko breadcrumbs, ¼ cup Seasoned breadcrumbs
Air fry: Place the chicken in the air fryer basket and spray the tops with cooking spray. Air fry the chicken breasts for 15 minutes, at 375°F. Halfway through cooking, flip the chicken and spray again with cooking spray.
