01 - Preheat oven to 400°F. 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 rest for 20 minutes to draw out bitterness. Rinse thoroughly and pat dry.
03 - Place flour in one shallow bowl, beaten eggs in a second, and combine breadcrumbs, Parmesan, and black pepper in a third bowl.
04 - Dredge each eggplant slice in flour, dip into beaten eggs, then coat with breadcrumb mixture. Arrange on prepared baking sheets.
05 - Lightly brush or drizzle the breaded eggplant slices with olive oil.
06 - Bake 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 marinara. Top with 1 cup marinara sauce, 1 cup shredded mozzarella, and 1/4 cup grated Parmesan cheese.
09 - Repeat layers with remaining eggplant, marinara, mozzarella, and Parmesan.
10 - Bake uncovered for 25 minutes until cheese is melted and bubbling.
11 - Allow to cool for 10 minutes. Garnish with chopped fresh basil before serving.
