Butterfly chicken breasts to create two, even halves. Using a meat mallet or any heavy item, pound out chicken breasts until 1/2" thickness.
Pat dry chicken and season with salt and pepper.
In a shallow bowl, whisk eggs and add salt and pepper.
In another bowl, add panko breadcrumbs and Italian-style breadcrumbs.
Finally, in one last bowl, add flour, salt, pepper, and garlic powder.
Dip each piece of chicken into flour first, then egg, then breadcrumb mixture. *Be sure to pat the breadcrumb mixture into the chicken.
Add oil to a large skillet over medium-high heat. Once hot (350-375 degrees), add chicken and cook on each side for about 2 minutes/until golden. *It does not need to cook through fully, at this point.
Remove and place on cooling rack. Repeat until all chicken is fried.
On a prepared baking sheet, add chicken, along with a heaping spoonful of marinara sauce to each breast. Then a piece or two of basil, followed by a sprinkle of mozzarella cheese and parmesan cheese.
Spray with cooking spray. Bake for 10-15 minutes until cheese is melted and bubbly, and chicken is cooked through (165 degrees).
Broil 1-2 minutes for an extra golden top.
Top with parsley or basil. Serve with pasta or fresh vegetables.
Enjoy!
