Preheat oven to 350.
Season the chicken with the salt and pepper. To setup a breading station, combine flour with the House seasoning in a bowl. In another bowl beat eggs with the milk. Combine the breadcrumbs, 1 cup of the grated cheese and parsley in a third bowl. Working in small batches, lightly coat each breast in the flour. Shake off any excess flour and transfer to the egg wash just long enough to coat and immediately transfer to the breadcrumbs, coating them thoroughly.
Heat the oil in a large skillet over medium-high heat. Add the chicken in small batches and lightly brown for 2-3 minutes on each side. Work in small batches so as not to overcrowd the skillet. Transfer them to a sheet pan lined with paper towels to drain excess oil.
Lightly oil an 11” x 13” baking dish and cover the bottom with 1 cup of the marinara. Arrange the chicken over the sauce, overlapping them if necessary. Sprinkle the chicken with ½ cup grated cheese and cover with the remaining marinara. Top with the mozzarella slices, spacing them evenly, and the remaining grated cheese. Cover with foil and bake until heated throughout and bubbling, about 20-30 minutes. Remove the foil and brown the top briefly under the broiler if desired.
Stack the basil leaves, roll them tightly and slice thin to make basil chiffonade. Allow to cool slightly before serving and top with the basil chiffonade.
