01 - Preheat the oven to 400°F and line two baking sheets with parchment paper.
02 - Arrange eggplant slices in a single layer on a rack or paper towels, sprinkle both sides with salt, and let sit for 20 minutes to remove bitterness. Rinse and pat dry thoroughly.
03 - Place flour in one shallow bowl, beaten eggs in a second, and a mixture of Italian-style breadcrumbs, 1/2 cup Parmesan, and black pepper in a third.
04 - Dredge each eggplant slice in flour, dip into beaten eggs, then coat evenly with breadcrumb mixture. Arrange coated slices on prepared baking sheets.
05 - Lightly drizzle or brush the breaded eggplant slices with olive oil to ensure crispiness during baking.
06 - Bake the slices for 20 minutes, flipping halfway through, until golden brown and crisp.
07 - Reduce oven temperature to 375°F. Spread 1/2 cup marinara sauce evenly in a 9x13-inch baking dish.
08 - Arrange half of the baked eggplant slices over the sauce, then top with 1 cup marinara, 1 cup shredded mozzarella, and 1/4 cup grated Parmesan.
09 - Add the remaining eggplant slices, followed by the remaining marinara sauce, shredded mozzarella, and Parmesan cheese.
10 - Bake uncovered for 25 minutes or until the cheese is melted, bubbly, and slightly golden.
11 - Allow to cool for 10 minutes before serving. Garnish with chopped fresh basil and additional Parmesan if desired.
