Traditional Eggplant Parmesan is undeniably delicious, but frying heavy breaded slices in batches of oil can be messy, labor-intensive, and grease-heavy. This Roasted Eggplant Parmesan offers a smarter, healthier approach: high-heat oven roasting caramelizes the eggplant slices until tender and sweet, creating a silky foundation that layered with marinara, melted fresh mozzarella, and sharp Parmesan cheese.
The secret to a non-soggy, perfectly tender eggplant bake is Salting the Eggplant Rounds to Draw Out Excess Water and Roasting at High Heat (425°F) Before Layering. Roasting cooks away trapped moisture and concentrates the natural umami flavor, ensuring your casserole bakes into thick, sliceable layers rather than a watery mess.

- Marinara Sauce: High-quality store-bought (like Rao’s Homemade) or fresh garlic-basil marinara.
- Mozzarella Cheese: Shredded low-moisture mozzarella for a bubbly melt, combined with fresh mozzarella slices for creaminess.

Step-by-Step Instructions
1.Salt & Sweat the Eggplant:15 min.
Slice 2 medium eggplants into ½-inch rounds. Arrange in a single layer on paper towels and sprinkle lightly with salt. Let sit for 15 minutes to draw out bitter juices and excess moisture, then blot thoroughly dry with paper towels.
2.High-Heat Roast the Slices:25 min.
Preheat oven to 425°F (220°C) and line two baking sheets with parchment paper. Arrange the dried eggplant slices on the sheets, brush both sides with ¼ cup olive oil, and season with ½ tsp garlic powder, ½ tsp Italian seasoning, salt, and pepper. Roast for 20 to 25 minutes, flipping halfway through, until tender and caramelized.
3.Layer in Casserole Dish:5 min.
Lower oven temperature to 375°F (190°C). Spread 1 cup of marinara sauce over the bottom of a 9×13-inch baking dish. Arrange half of the roasted eggplant slices in an even layer. Top with 1 cup marinara, 1 cup shredded mozzarella, ½ cup grated Parmesan, and a handful of torn fresh basil. Repeat with remaining eggplant, marinara, mozzarella, and Parmesan.
4.Bake Until Bubbly & Golden:25 min.
Cover the dish loosely with foil and bake at 375°F (190°C) for 15 minutes. Remove foil and bake uncovered for an additional 10 to 12 minutes until the cheese is melted, bubbling, and golden brown around the edges.
5.Rest, Garnish & Serve:10 min.
Let the casserole rest undisturbed for 10 minutes (this allows the layers to set so slices hold their shape). Top with fresh basil leaves and extra Parmesan before serving warm.
Expert Tips for Success
- Don’t Skip the Rest Time: Freshly baked Eggplant Parmesan is molten right out of the oven! Letting it sit for 10 minutes allows the melted cheese and tomato juices to firm up so you can cut clean, beautiful slices.
- Use Low-Moisture Mozzarella Inside: While fresh mozzarella tastes amazing on top, low-moisture mozzarella inside the layers prevents excess water from pooling at the bottom of your baking dish.
- Keep Slices Uniform: Cut your eggplant into uniform ½-inch thick rounds so every slice roasts at the exact same rate.
