Preheat the oven to 425°F. Butterfly the chicken breasts by cutting through the middle of each lengthwise to create six cutlets. Pound each piece between sheets of plastic wrap using a rolling pin or meat mallet until they are an even thickness.

In a medium bowl, whisk together the eggs with a pinch of salt and pepper. In a separate medium bowl, whisk to combine the flour with 1 teaspoon of salt and ½ teaspoon of pepper. In a third medium bowl, combine the Panko and seasoned breadcrumbs with ½ cup grated Parmesan (28g), chopped parsley and mix together.

Dredge each piece of chicken in the flour mixture and tap off any excess. Dip in the egg and let the excess drip off. Dredge on both sides in the breadcrumb mixture and press down so the breadcrumbs stick and form a nice layer.

In a large skillet, pour the olive oil and heat over medium-high heat until the oil shimmers. Working in batches, add 2 to 3 pieces of chicken to the pan and cook until golden brown on both sides, about 4 minutes per side, adjusting the heat as needed. Transfer to a paper-towel-lined plate to absorb any excess grease.

Transfer to a baking sheet and top each breast with ¼ to ⅓ cup marinara sauce, a generous sprinkle of mozzarella, and about a tablespoon of Parmesan.

Bake in the oven until the chicken is cooked through and the cheese is melted and golden, 15-20 minutes. Remove from the oven and garnish with basil and parsley leaves. Serve over spaghetti.
