Ingredients

Core Vegetables

Eggplant, sliced into ½-inch rounds

Tomatoes, large ripe, sliced

Zucchini, sliced into rounds or half-moons

Onion, sliced or diced

Cheeses

Mozzarella, shredded or sliced

Parmesan, freshly grated

Optional: cheddar or Italian cheese blend

Seasonings and Herbs

2–3 cloves garlic, minced

Fresh basil leaves, for garnish and layering

Olive oil, for roasting and drizzling

Salt and black pepper to taste

Optional garlic powder for extra depth

Instructions

Preheat the oven to 200°C and lightly grease a baking dish with olive oil.

Arrange sliced eggplant on a tray, sprinkle with salt, and let it sit for a few minutes to draw out excess moisture. Pat dry and lightly brush with olive oil.

In a pan or oven tray, lightly roast or sauté eggplant, zucchini, and onions for about 10–12 minutes until slightly softened. This helps reduce excess water in the casserole.

In the baking dish, start layering the vegetables. Begin with onions at the bottom, followed by eggplant, zucchini, and tomato slices. Sprinkle minced garlic, salt, and pepper between layers for even seasoning.

Add a drizzle of olive oil over the layers to enhance roasting and flavor.

Sprinkle a layer of mozzarella cheese over the vegetables, then add Parmesan on top for a salty, golden finish.

Cover the dish with foil and bake for about 25 minutes to allow the vegetables to soften and blend flavors.

Remove the foil and bake for another 10–15 minutes until the cheese is melted, bubbly, and lightly golden on top.

Once baked, let the casserole rest for a few minutes. Garnish generously with fresh basil leaves before serving.

Tips

Salt eggplant before cooking to remove bitterness and excess moisture

Pre-roast vegetables slightly to avoid a watery casserole

Use ripe tomatoes for better flavor and natural sweetness

Do not overload with cheese or it may become too heavy

Layer vegetables evenly for consistent cooking

Let the casserole rest before serving so it holds shape better

Use fresh basil at the end to keep flavor bright

Drizzle olive oil lightly between layers for richness

Bake covered first to lock in moisture, then uncovered for browning

Slice vegetables evenly for uniform texture and cooking

Variations

Add ground meat or chicken for a protein-rich version

Include mushrooms for deeper earthy flavor

Use ricotta between layers for extra creaminess

Replace mozzarella with feta for a tangier taste

Use yellow squash instead of zucchini for variation
