01 - Preheat the oven to 425°F. Line two baking sheets with parchment paper and lightly coat with olive oil spray or brush with olive oil.
02 - Wash the eggplants thoroughly and slice into 1/2-inch thick rounds. Arrange slices in a single layer, sprinkle lightly with salt, and let rest for 15 minutes to draw out excess moisture. Pat each slice dry with a clean kitchen towel.
03 - Arrange three shallow bowls for breading: fill the first with the all-purpose flour, whisk the eggs and milk together in the second, and combine the breadcrumbs, Parmesan cheese, dried oregano, garlic powder, salt, and black pepper in the third.
04 - Working one slice at a time, dredge each eggplant round through the flour, shaking off excess. Dip into the egg wash to coat evenly, then press firmly into the seasoned breadcrumb mixture, coating both sides thoroughly.
05 - Place the breaded eggplant slices in a single layer on the prepared baking sheets, leaving space between each piece. Drizzle the tops lightly with olive oil or mist with olive oil spray.
06 - Bake on the center rack for 15 minutes, then carefully flip each slice and continue baking for an additional 15 minutes, until both sides are golden brown and the coating is crisp.
07 - Remove from the oven and serve immediately while hot and crispy. Pair with warm marinara sauce for dipping, or serve alongside your main course.
