Introduction
This eggplant casserole is a comforting and flavorful dish featuring tender roasted eggplant slices layered with marinara, cheeses, and crispy toasted breadcrumbs. It’s perfect for a cozy dinner and easy enough for home cooks to prepare with simple ingredients.

Ingredients
- ¾ teaspoon oregano
- ¾ teaspoon basil
- ¾ teaspoon garlic powder
- ¾ teaspoon parsley
- 3 medium ripe eggplants (about 3 ½ lbs)
- Salt and pepper, to taste
- 3 tablespoons olive oil
- 1 cup panko breadcrumbs
- 2 tablespoons salted butter, melted
- ½ cup grated Parmesan cheese, divided
- 2 ½ cups shredded mozzarella cheese, divided
- 24 oz marinara sauce, divided
Instructions
- Step 1: Preheat your oven to 425° F.
- Step 2: In a small bowl, combine the oregano, basil, garlic powder, and parsley. Set aside. Measure out all remaining ingredients to have them ready.
- Step 3: Slice the eggplants into ¼-inch thick slices. If some slices from the wider part of the eggplant are very large, cut them in half. Place the slices on two lightly greased, light-colored baking sheets.
- Step 4: Drizzle olive oil over the eggplant slices, season with salt and pepper, then sprinkle with the prepared herb mixture. Toss gently with your hands to coat evenly and spread the slices in an even layer, overlapping slightly if needed.
- Step 5: Bake the eggplant for 20 minutes or until cooked to your liking. Once done, remove from the oven and reduce the oven temperature to 375° F.
- Step 6: Combine the panko breadcrumbs with melted butter in a medium bowl. Transfer this mixture to a medium skillet over medium heat and toast, stirring continuously, until golden brown, about 2-3 minutes. Remove from heat and set aside.
- Step 7: Spread a thin layer of marinara sauce on the bottom of a 9 x 13-inch baking dish.
- Step 8: Arrange half of the roasted eggplant slices evenly on the bottom, overlapping slightly. Sprinkle half of the toasted breadcrumbs over the eggplant. Dollop half of the marinara sauce, then sprinkle with half of the Parmesan and half of the mozzarella.
- Step 9: Layer the remaining eggplant slices on top, followed by the remaining marinara sauce, Parmesan cheese, and mozzarella cheese.
- Step 10: Cover the dish and bake for 18 minutes. Remove the cover, sprinkle the remaining breadcrumbs over the top, and bake uncovered for up to 5 more minutes. Watch carefully to prevent the breadcrumbs from browning too much. Remove from oven and serve warm.
Tips & Variations
- Try salting the eggplant slices and letting them sit for 20 minutes before roasting to reduce bitterness and excess moisture.
- Use fresh herbs if available for a brighter flavor, adjusting quantities to taste.
- For a vegan version, substitute cheeses with your favorite plant-based alternatives and use olive oil or a vegan butter substitute.
- Add cooked ground meat or sautéed mushrooms for added texture and protein.
Storage
Store leftover casserole in an airtight container in the refrigerator for up to 3 days. Reheat in the oven at 350° F until warmed through to maintain the crispy topping. Avoid microwaving if you want to keep the breadcrumbs crunchy.

FAQs
Can I use frozen eggplant for this recipe?
While fresh eggplant is preferred for best texture and flavor, you can use frozen eggplant if thawed and drained well to remove excess moisture before roasting.
How do I prevent the eggplant from becoming soggy?
Roasting the eggplant slices at a high temperature helps evaporate moisture and keeps the slices firm. Also, avoid slicing them too thin, as thinner slices tend to shrivel and become soggy.

Ingredients
Seasoning Mix
- ¾ teaspoon oregano
- ¾ teaspoon basil
- ¾ teaspoon garlic powder
- ¾ teaspoon parsley
Eggplant and Preparation
- 3 medium ripe eggplants (about 3 1/2 lbs)
- Salt and pepper, to taste
- 3 tablespoons olive oil
Casserole Components
- 1 cup panko breadcrumbs
- 2 tablespoons salted butter, melted
- ½ cup grated Parmesan cheese, divided
- 2 ½ cups shredded mozzarella cheese, divided
- 24 oz. marinara sauce, divided
Instructions
- Preheat and prepare seasoning: Preheat your oven to 425° F. In a small bowl, combine oregano, basil, garlic powder, and parsley. Set this seasoning mix aside while you prepare the other ingredients.
- Slice the eggplant: Cut the eggplants into ¼-inch thick slices. If slices from the wider parts are very large, cut them in half to ensure more even cooking. Lay the slices in a single layer on two lightly greased, light-colored baking sheets.
- Season the eggplant: Drizzle the olive oil over the eggplant slices. Season them with salt, pepper, and the prepared herb mixture. Toss gently with your hands to coat the slices evenly without overcrowding, allowing slight overlaps if necessary.
- Roast the eggplant: Place the baking sheets in the oven and bake for 20 minutes, or until the eggplant reaches your desired tenderness. Once done, set aside and reduce oven temperature to 375° F in preparation for assembling the casserole.
- Toast the breadcrumbs: Mix the melted butter with the panko breadcrumbs in a bowl. Transfer this mixture to a medium skillet set over medium heat. Toast the breadcrumbs for 2-3 minutes, stirring continuously until golden brown. Remove from heat and set aside.
- Assemble the casserole base: Spread a light layer of marinara sauce evenly over the bottom of a 9×13-inch baking dish.
- Layer the casserole: Arrange half of the roasted eggplant slices over the marinara sauce. Sprinkle half of the toasted breadcrumbs evenly on top. Dollop half of the remaining marinara sauce over the breadcrumbs, then sprinkle with half of the Parmesan and half of the mozzarella cheese.
- Add second layer: Repeat the layering process with the remaining eggplant, marinara sauce, Parmesan, and mozzarella cheese.
- Bake covered: Cover the baking dish with foil or a lid and bake for 18 minutes at 375° F.
- Finish with breadcrumbs and bake uncovered: Remove the cover, sprinkle the remaining toasted breadcrumbs evenly on top, and return the casserole to the oven. Bake uncovered for up to 5 more minutes, watching carefully to avoid over-browning the breadcrumbs. Remove from oven and serve warm.
Notes
- For the best flavor and texture, use ripe but firm eggplants about 3 ½ pounds total.
- If eggplant slices are too thin, they may shrivel excessively during roasting.
- Using light-colored baking sheets helps prevent the eggplant from browning too quickly.
- Adjust seasoning according to your taste preferences.
- Ensure you watch the casserole closely during the final bake to prevent breadcrumbs from burning.
