Preheat your oven to 400°F. Line two baking sheets with parchment paper and spray lightly with cooking spray.
In a shallow bowl, combine the panko breadcrumbs, ¼ cup Parmesan cheese, and Italian seasoning. Place the beaten egg whites in another shallow bowl.
Dip each eggplant slice into the egg whites, then press into the breadcrumb mixture to coat both sides. Arrange on the prepared baking sheets.
Spray the tops of the eggplant slices lightly with cooking spray. Bake for 20-25 minutes, flipping halfway through, until golden and crispy.
Spread ½ cup marinara sauce in the bottom of a 9x13-inch baking dish. Layer half the eggplant slices over the sauce, then top with ¾ cup marinara, half the mozzarella, and 2 tablespoons Parmesan.
Repeat with remaining eggplant, marinara, and cheeses. Bake uncovered at 375°F for 15 minutes until bubbly.
Let rest for 5 minutes, garnish with fresh basil, and serve. Each portion is approximately 375 calories.
