Preheat your oven to 375°F (190°C).
Scoop out the flesh of the eggplants, leaving about ½ inch of the shell. Chop the scooped-out flesh and set aside.
Place the eggplant shells on a baking sheet, drizzle with olive oil, and season with salt and pepper. Bake for 20 minutes.
In a mixing bowl, combine the chopped eggplant flesh, marinara sauce, half of the mozzarella, half of the Parmesan, oregano, and basil. Mix well.
Fill the baked eggplant shells with the mixture, top with the remaining mozzarella and Parmesan cheese.
Bake for another 20 minutes, or until the cheese is melted and bubbly.
Remove from the oven and let cool for a few minutes before serving.
