Step 1: Prepare the Aubergines

• Slice the Aubergines: Cut the aubergines into 1/4 inch (0.6 cm) thick rounds.
• Season and Drain: Sprinkle salt on the slices and let them drain in a colander for about 30 minutes. This removes excess moisture and bitterness.
• Fry the Aubergines: Heat olive oil in a large frying pan over medium heat. Fry the aubergine slices until golden brown on both sides. Drain on paper towels to remove excess oil.

Step 2: Make the Tomato Sauce

• Sauté the Aromatics: In a saucepan, heat a little olive oil and sauté the chopped onion and minced garlic until soft and fragrant.
• Add Tomato Sauce: Pour in the tomato sauce and simmer for 10-15 minutes. Season with salt and pepper to taste.

Step 3: Assemble the Parmigiana

• Layer the Ingredients: In a baking dish, spread a layer of tomato sauce at the bottom. Add a layer of fried aubergine slices on top. Sprinkle with Parmesan and mozzarella cheese. Repeat the layers until all ingredients are used, finishing with a layer of cheese.
• Add Fresh Basil: Scatter torn basil leaves between the layers for extra flavor.

Step 4: Bake the Dish

• Preheat the Oven: Set your oven to 375°F (190°C).
• Bake: Place the baking dish in the oven and bake for 25-30 minutes, until the cheese is bubbly and golden brown.
• Rest Before Serving: Let the dish sit for about 10 minutes before serving to allow the flavors to meld.
