Preheat oven to 375°F and grease a 9x13-inch baking dish.
Sprinkle eggplant slices with salt and let sit for 20 minutes, then pat dry with paper towels.
Dip each eggplant slice in beaten eggs, then coat with breadcrumbs mixed with basil and oregano.
Spread 1 cup marinara sauce in bottom of prepared baking dish.
Layer half the eggplant slices over sauce, top with 1 cup marinara, 1 cup mozzarella, and 1/2 cup Parmesan.
Repeat layers with remaining eggplant, sauce, and cheeses.
Drizzle olive oil over the top and cover with foil.
Bake covered for 30 minutes, then uncover and bake 15 minutes more until cheese is golden and bubbly.
