Ingredients

For the Baked Eggplant Slices

1 .8kg (4 lbs) large eggplants (aubergines) – about 5, sliced lengthways 8mm (1/3″)-thick (skin on)
1 /4 cup olive oil (for brushing)

For the Layers

1 2/3 cups parmesan cheese, finely grated
2 cups fresh basil leaves (loosely packed), stalks reserved
1 1/2 cups mozzarella cheese, shredded (for topping)

For the Sugo (Tomato Sauce)

2 tablespoons extra virgin olive oil
1 large onion, finely diced
5 garlic cloves, finely minced
600 ml (20oz) tomato passata
400 g (14oz) canned tomatoes, crushed or finely chopped
1 1/2 teaspoons white sugar
1 1/2 tablespoons fresh oregano, finely chopped (or 1/2 teaspoon dried oregano)
1 cup water
3 /4 teaspoon salt
1 /4 teaspoon black pepper

Instructions

Preparing the Eggplant

1 Preheat your oven to 220°C (430°F) or 200°C (390°F) for fan-forced ovens. Line three large baking trays with parchment paper, ensuring you have enough oven space to accommodate all trays.
2 Using a silicone pastry brush, generously brush each eggplant slice on both sides with olive oil. This step is crucial for achieving that golden, caramelized exterior while keeping the interior creamy and tender.
3 Arrange eggplant slices in a single layer across the prepared trays, ensuring they don’t overlap. Bake for 35-45 minutes, turning the eggplant halfway through cooking. The slices should be golden brown and completely tender when pierced with a fork.
4 Rotate trays as needed during baking—place one tray on the top shelf, one in the middle, and one on the oven floor if necessary. Remove each tray as it finishes and allow the eggplant to cool completely on the trays.

Making the Sugo

5 While the eggplant bakes, heat 2 tablespoons extra virgin olive oil in a large cast iron skillet or heavy-bottomed pan over medium-high heat until shimmering.
6 Add the finely diced onion and minced garlic, sautéing for 3 minutes until softened and just beginning to develop golden edges. The aromatics should be fragrant but not browned.
7 Pour in the tomato passata, crushed canned tomatoes, water, oregano, and sugar. Stir thoroughly and bring the mixture to a gentle simmer, then reduce heat to medium-low.
8 Simmer the sauce uncovered for 30-40 minutes, stirring occasionally with a wooden spoon until thickened to a spreadable consistency. Add the reserved basil stalks halfway through cooking to infuse maximum flavor.
9 The final sauce should be slightly thicker than typical pasta sauce—spreadable without being watery, but not paste-like. Add water gradually if it becomes too thick. Remove and discard basil stalks, then season with salt and pepper.

Assembly and Final Baking

10 Reduce oven temperature to 180°C (350°F) or 160°C (320°F) for fan-forced ovens. Smear a thin layer of tomato sauce across the bottom of a 23 x 33cm (9 x 13 inch) baking dish.
11 Create the first layer by arranging one-third of the baked eggplant slices to cover the base—some overlap is perfectly fine. Spread one-third of the remaining sugo evenly over the eggplant, then drizzle lightly with olive oil.
12 Sprinkle one-third of the grated parmesan and one-third of the fresh basil leaves over the sauce layer, distributing evenly for consistent flavor throughout.
13 Repeat the layering process: another third of eggplant, tomato sauce, olive oil drizzle, parmesan, and basil leaves for the second layer.
14 For the final top layer, arrange the remaining eggplant slices, spread with the last of the tomato sauce, and drizzle with olive oil. Reserve the remaining basil for garnishing after baking. Top with remaining parmesan, then scatter all the mozzarella cheese evenly across the surface.
15 Bake for 25 minutes until the top is bubbling vigorously and golden brown. The cheese should be melted and slightly caramelized around the edges.
16 Allow the parmigiana to rest for 5-10 minutes before serving—this resting period makes slicing much neater and prevents the layers from sliding apart. Garnish with the reserved fresh basil leaves and cut into squares like lasagna. Serve with an optional sprinkle of extra parmesan cheese.

Perfect Pairing Suggestions

Wine Pairings

A medium-bodied Chianti Classico beautifully complements the rich tomato sauce and aged cheeses, while the wine’s natural acidity cuts through the richness. For white wine lovers, a Vermentino or Pinot Grigio provides crisp contrast to the creamy, layered textures. Sangiovese offers earthy notes that harmonize with the roasted eggplant’s smoky sweetness.

Non-Alcoholic Beverages

Sparkling water with lemon cleanses the palate between rich bites, while Italian sodas like Aranciata provide citrusy brightness. For a warming option, herbed iced tea with fresh basil and mint echoes the Mediterranean flavors. Pomegranate juice mixed with sparkling water offers antioxidant benefits and tart contrast.

Side Dish Recommendations

A crisp arugula salad with lemon vinaigrette cuts through the richness while adding peppery bite and fresh texture. Roasted garlic bread or focaccia helps soak up any delicious sauce. Grilled asparagus or sautéed spinach with garlic adds color and complements the Italian herb profile. Marinated olives and roasted red peppers create an authentic antipasto experience.

Complete Meal Ideas

Start with bruschetta or caprese skewers to set the Italian mood. Follow the parmigiana with a light lemon granita or fresh fruit to cleanse the palate. For entertaining, serve antipasto platters before the main course and finish with espresso and biscotti for an authentic Italian dining experience.

Pro Tips and Troubleshooting

Professional Techniques

Salt your eggplant slices and let them drain in a colander for 30 minutes before cooking—this removes bitterness and prevents the final dish from becoming watery. Use a kitchen scale to ensure even portions when layering, and always let the assembled dish rest overnight in the refrigerator before baking for the best flavor development and easier slicing.

Common Mistake Prevention

Never skip the cooling period for baked eggplant—hot eggplant releases steam that makes your carefully crafted layers soggy. Don’t oversauce the layers; the eggplant will release moisture during the final bake, and too much liquid creates a mushy texture. Resist the urge to cut into the finished dish immediately—the 10-minute rest is essential for clean, stable slices.

Storage and Make-Ahead Strategy

This parmigiana actually improves after 24 hours in the refrigerator as flavors meld and develop. Assemble completely, cover tightly with aluminum foil, and refrigerate for up to 3 days before baking. For longer storage, freeze the assembled dish for up to 3 months—thaw completely before baking and add an extra 10 minutes to the cooking time. Leftover portions keep refrigerated for 5 days and reheat beautifully in a 350°F (175°C) oven.

Troubleshooting Guide

If your final dish seems watery, the eggplant wasn’t properly drained or the sauce was too thin. Next time, cook the sauce longer and always salt the eggplant. For uneven browning, rotate your baking dish halfway through the final bake and use the middle oven rack for consistent heat circulation.

This legendary Italian comfort food transforms simple vegetables into something absolutely spectacular—layers of golden eggplant, rich tomato sauce, and bubbling cheese that create the kind of meal people remember long after the last bite. The time investment pays off in spades when you slice into those perfect layers and watch everyone’s faces light up with pure satisfaction.
