01 - Preheat the 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 remove bitterness. Rinse and pat dry thoroughly.
03 - Place flour in a shallow bowl, beaten eggs in a second bowl, and combine breadcrumbs, Parmesan, and black pepper in a third bowl.
04 - Dredge each eggplant slice in flour, dip in beaten eggs, then coat evenly with breadcrumb mixture. Arrange on prepared baking sheets.
05 - Lightly drizzle or brush olive oil over breaded eggplant slices. Bake for 20 minutes, flipping halfway through, until golden and crispy.
06 - Reduce oven temperature to 375°F. Spread 1/2 cup marinara sauce in a 9x13-inch baking dish. Layer half the baked eggplant slices, then top with 1 cup marinara sauce, 1 cup mozzarella, and 1/4 cup Parmesan cheese.
07 - Repeat layering with remaining eggplant slices, marinara sauce, mozzarella, and Parmesan cheese.
08 - Bake uncovered for 25 minutes until cheese is melted and bubbly.
09 - Allow to cool for 10 minutes before garnishing with fresh basil and additional grated Parmesan cheese.
