How to Make Eggplant Casserole with Mozzarella, Parmesan, and Toasted Breadcrumbs Recipe

Step 1: Prep Your Oven and Seasonings

Start by preheating your oven to 425° F, which will give the eggplant slices that perfect roast. While it warms up, mix oregano, basil, garlic powder, and parsley in a small bowl to create a fragrant seasoning blend that will elevate the casserole’s flavor profile.

Step 2: Slice and Season the Eggplant

Slice the eggplants into ¼-inch thick rounds. The thickness is important; thinner slices can shrivel during roasting, while thicker slices won’t cook through evenly. Lightly grease two baking sheets and arrange the eggplant slices in a single layer. Drizzle them with olive oil, season with salt and pepper, then sprinkle the herb blend evenly. Use your hands to toss the slices gently so every piece is coated in that lovely seasoning.

Step 3: Roast the Eggplant

Place the seasoned eggplant into the oven and roast for 20 minutes. This will soften the eggplant and bring out a subtle sweetness. Once done, remove the eggplant and reduce the oven temperature to 375° F, prepping for the casserole baking stage.

Step 4: Toast the Breadcrumbs

While the eggplant cools slightly, combine the panko breadcrumbs with melted butter. Transfer the mixture to a skillet over medium heat and toast, stirring often, for 2 to 3 minutes until the crumbs turn a gorgeous golden brown. Toasting adds a nutty flavor and a satisfying crunch that’s pure magic on top of the cheesy layers.

Step 5: Assemble the Casserole

Spread a light layer of marinara sauce on the bottom of a 9 x 13-inch baking dish. Layer half of the roasted eggplant on top, slightly overlapping. Sprinkle half of the toasted breadcrumbs evenly, then add dollops of half the marinara sauce, followed by half the Parmesan and mozzarella cheeses. Repeat the layering with the remaining ingredients, finishing with the top layer of mozzarella and Parmesan.

Step 6: Bake Until Bubbling and Golden

Cover the casserole and bake for 18 minutes to let all the cheeses melt and flavors meld. After this, remove the cover and scatter the remaining toasted breadcrumbs on top, then return it to the oven uncovered for up to 5 minutes. Keep a close eye so the breadcrumbs reach a golden crisp without burning. Once done, remove from the oven and let it rest briefly before serving.

Make Ahead and Storage

Storing Leftovers

Leftover eggplant casserole can be stored tightly covered in the refrigerator for up to 4 days. Proper storage helps maintain moisture while preserving the crispness of the breadcrumb topping when reheated carefully.

Freezing

This casserole freezes beautifully. Wrap it tightly in plastic wrap and aluminum foil or place in an airtight container, then freeze for up to 3 months. When ready, thaw overnight in the refrigerator before reheating to maintain texture and flavor.

Reheating

Reheat leftovers in a 350° F oven, covered with foil to retain moisture, for about 20 minutes. Uncover during the last 5 minutes to bring back that golden breadcrumb crunch. This method helps restore the freshly-baked feel and keeps the cheese melty and inviting.

FAQs

Can I use a different type of cheese besides mozzarella and Parmesan?

Absolutely! While mozzarella and Parmesan are traditional and melt well, you can experiment with provolone, fontina, or even a sprinkle of ricotta for creaminess. Just keep in mind the balance of flavors – Parmesan adds sharpness, while mozzarella offers stretchiness.

Do I need to peel the eggplants before roasting?

Peeling is optional. The skin provides structure during roasting and adds subtle earthiness. If you prefer a softer texture or find the skin tough, peeling is a fine choice. Just be sure to slice uniformly for even cooking.

How do I prevent the eggplant from becoming soggy?

Slicing the eggplant evenly, roasting it at a high temperature, and ensuring it’s well-seasoned with oil helps to reduce sogginess. Overlapping should be minimal so slices cook properly. Also, using a light hand with marinara between layers prevents excess moisture.

Can this casserole be made vegan or dairy-free?

Yes! Substitute mozzarella and Parmesan for vegan cheeses or nutritional yeast, and use a plant-based butter for toasting the breadcrumbs. The flavors will be slightly different but still delicious and comforting.

What’s the best way to reheat this casserole to keep the topping crisp?

Reheating uncovered in the oven at 350° F for the last few minutes is key to reviving the breadcrumb topping’s crispiness. Avoid microwaving if you want to keep that crunch, as it tends to make the topping soggy.
