01 - Preheat the oven to 425°F. Line two baking sheets with parchment paper and lightly coat with olive oil spray.
02 - Wash the eggplants thoroughly and slice into 1/2-inch thick rounds. Sprinkle slices lightly with salt and let rest for 15 minutes to draw out excess moisture, then pat dry with paper towels.
03 - Arrange three shallow bowls: fill the first with all-purpose flour, the second with eggs whisked together with milk, and the third with breadcrumbs combined with grated Parmesan, dried oregano, garlic powder, salt, and black pepper.
04 - Working one slice at a time, dredge each eggplant round through the flour, shaking off excess. Dip into the egg wash, then press firmly into the seasoned breadcrumb mixture, coating both sides evenly.
05 - Place the breaded slices in a single layer on the prepared baking sheets. Drizzle or spray the tops lightly with olive oil to promote even browning.
06 - Bake for 15 minutes, then carefully flip each slice and continue baking for another 15 minutes until the coating is golden brown and crunchy.
07 - Serve immediately while hot and crispy, paired with warm marinara sauce for dipping, or alongside your main course as a satisfying side dish.
