In another shallow dish, beat the egg until smooth. Set aside.
In a third shallow dish bowl, whisk together the breadcrumbs, parmesan, garlic, salt and pepper.
Start by placing one chicken breast in the flour dish and flip until all the chicken is coated in flour.
Place the chicken in the egg and cover to coat.
Finally, place the chicken in the breadcrumb mixture and coat. Place on a baking sheet lined with a wire rack and set aside.
Repeat that entire process with the other chicken breast.
Bake the chicken for 17 - 20 mintues until the internal temperature reaches 165ºF. Remove from the oven, allow to cool for 5 minutes, then slice and serve.
