Tasty Baked Eggplant Parmesan Casserole

Here’s my go-to baked eggplant parmesan casserole recipe, with layers of crispy breaded eggplant, rich marinara sauce, and plenty of melted cheese, all baked until golden brown and bubbly.

This eggplant parmesan has become a regular weeknight dinner at our house. I often make a double batch because the leftovers taste even better the next day. Nothing beats having a ready-to-heat homemade meal in the fridge, right?

What Kind of Eggplant Should I Use?

For this casserole, you’ll want to look for the classic Italian or Globe eggplants – those deep purple, oval-shaped ones you commonly see at the grocery store. When selecting your eggplants, pick ones that feel firm and heavy for their size, with smooth, shiny skin free from brown spots or blemishes. The best eggplants for this dish are medium to large in size, but not giant ones, as those tend to have more seeds and can be more bitter. If you’re at the store and give the eggplant a gentle squeeze, it should bounce back slightly – if your finger leaves an indent, the eggplant is too ripe and might be mushy when cooked.

Options for Substitutions

This eggplant parmesan recipe can be tweaked in several ways to match what you have on hand:

• Eggplant: While eggplant is the star here and can’t really be substituted, you can use any variety of eggplant – Italian, globe, or even Japanese eggplants (though you’ll need more of the smaller ones).
• Mozzarella cheese: You can use full-fat mozzarella instead of part-skim, or try provolone for a sharper taste. For a dairy-free version, use your favorite plant-based mozzarella alternative.
• Marinara sauce: Any tomato-based pasta sauce works here. You can use homemade or store-bought, regular marinara, arrabbiata for some heat, or even pizza sauce in a pinch.
• Panko breadcrumbs: Regular breadcrumbs work fine, they’ll just give you a slightly different texture. For a low-carb option, try crushed pork rinds or almond meal. Just watch them carefully as they can brown faster.
• Parmesan cheese: Pecorino Romano or Grana Padano make good swaps for parmesan. For a dairy-free version, nutritional yeast can provide that nutty, cheesy flavor.
• Italian herbs: If you don’t have an Italian herb blend, use any mix of dried oregano, basil, thyme, or rosemary. Fresh herbs work too – just double the amount called for.

Watch Out for These Mistakes While Baking

The biggest mistake when making eggplant parmesan is skipping the salt step – salting your eggplant slices and letting them sit for 30 minutes helps draw out excess moisture and bitterness, ensuring your casserole doesn’t turn watery.

Another common error is cutting the eggplant too thick, which can lead to undercooked, spongy pieces – aim for ¼-inch thick slices and arrange them in a single layer when baking for even cooking.

To prevent a soggy bottom layer, avoid adding too much marinara sauce at once, and make sure to pat your eggplant dry with paper towels after the salting process.

For the crispiest top layer, try broiling the casserole for the final 2-3 minutes, keeping a close eye to prevent burning, and let it rest for 10 minutes before serving to allow the layers to set properly.

What to Serve With Eggplant Parmesan?

This Italian-style casserole pairs perfectly with a simple side of pasta tossed in olive oil and garlic, or you can keep it light with a fresh arugula salad dressed in lemon juice. Since the dish is already rich and cheesy, I like to balance it out with some roasted broccoli or sautéed green beans on the side. For a complete Italian dinner experience, serve it with some warm crusty bread or garlic knots to soak up any extra sauce – trust me, you won’t want to leave a single drop behind!

Storage Instructions

Keep Fresh: This eggplant parmesan casserole stays good in the fridge for up to 4 days when stored in an airtight container. The flavors actually get better after a day or two as everything melds together nicely. It’s perfect for making ahead for busy weeknight dinners!

Freeze: You can freeze this casserole for up to 3 months! Let it cool completely, then wrap it tightly in foil and place in a freezer-safe container. Pro tip: you can also freeze individual portions in separate containers for easy grab-and-go meals.

Reheat: To warm up your casserole, pop it in the oven at 350°F for about 20-25 minutes until heated through. If reheating from frozen, thaw overnight in the fridge first. For single servings, the microwave works well too – just heat in 30-second intervals until warm. Add a sprinkle of fresh basil before serving to make it taste like it’s fresh from the oven!

Ingredients

For the roasted eggplant:

• 1/4 tsp black pepper
• 1/2 tsp paprika
• 1/2 tsp garlic powder
• 2 tbsp olive oil
• 2.5 lb eggplant (cut into 1/2-inch thick rounds)
• 1 tsp kosher salt

For the casserole:

• 2 cups marinara sauce (I like Rao’s Homemade Marinara Sauce)
• 2 cups shredded mozzarella cheese

For the topping:

• 3/4 tsp dried Italian herbs
• 1/3 cup panko breadcrumbs (for extra crispiness)
• 1/3 cup parmesan cheese (freshly grated for best flavor)
• 1 tbsp olive oil
• 1/2 tsp garlic powder

For serving (optional):

• fresh basil leaves (torn or chopped for garnish)

Step 1: Prepare the Oven and Baking Sheets

Preheat the oven to 425℉.

Line two baking sheets with parchment paper or aluminum foil for easy cleanup, or lightly grease the pans with oil or oil spray.

This will ensure the eggplant slices do not stick while roasting.

Step 2: Prepare and Season the Eggplant

Cut the ends off the eggplant.

You can peel alternating strips of the eggplant peel, peel it entirely, or leave all the skin on based on your preference.

Slice the eggplants into ¼-inch thick rounds.

Arrange the eggplant rounds on the prepared baking sheets.

Lightly brush both sides with 2 tablespoons of oil or use oil spray to coat them evenly.

In a small bowl, combine salt, pepper, paprika, and ½ teaspoon garlic powder.

Sprinkle this seasoning mix evenly over the eggplant slices.

Step 3: Roast the Eggplant

Roast the eggplant rounds in the preheated oven until they become tender and lightly golden brown.

This should take about 20 to 25 minutes.

While the eggplant is roasting, you can prepare the casserole dish.

Step 4: Assemble the Casserole

Grease a 9-by-13-inch casserole dish with oil or oil spray.

Spread a heaping ½ cup of marinara sauce evenly across the bottom of the dish.

Layer half of the roasted eggplant over the sauce.

Top with another heaping ½ cup of marinara sauce, and sprinkle 1 cup of shredded mozzarella cheese evenly over the sauce.

Repeat the layering process with the remaining eggplant, sauce, and mozzarella cheese.

Step 5: Add the Breadcrumb Topping

In a small bowl, mix together the breadcrumbs, Parmesan cheese, 1 tablespoon of olive oil, ½ teaspoon of garlic powder, and Italian seasoning.

Sprinkle this breadcrumb mixture evenly over the top of the assembled casserole to add a flavorful and crispy topping.

Step 6: Bake and Serve

Bake the casserole in the oven until it is bubbling and golden brown on top, about 15 minutes.

Serve warm, optionally garnished with fresh torn basil leaves.

This dish can be enjoyed as a side or served over cooked pasta with a simple side salad.

Store any leftovers in an airtight container in your fridge for up to 4 days.
