Eggplant is a versatile vegetable that is the star of this casserole. It has a mild, slightly sweet flavor that pairs well with the other ingredients. Choose eggplants that are firm and shiny, with no soft spots or blemishes.


Zucchini is another key ingredient in this casserole. It adds a fresh and slightly crunchy element to the dish. Look for zucchini that is plump and has a bright green color. Avoid zucchini that is soft or wrinkled.

Olive oil

Olive oil is used to coat the vegetables before roasting, giving them a rich and savory flavor. It also helps to prevent them from sticking to the baking dish. Opt for extra-virgin olive oil for the best flavor.


Onions provide a savory and slightly sweet flavor to the casserole. They also add a nice texture when cooked. You can use yellow, white, or red onions, depending on your preference.


Garlic adds a wonderful aroma and flavor to the casserole. It complements the other ingredients beautifully. Use fresh garlic cloves for the best taste.

Tomato sauce

Tomato sauce forms the base of the casserole and adds a delightful tanginess. You can use store-bought tomato sauce or make your own by simmering tomatoes with herbs and spices.

Mozzarella cheese

Mozzarella cheese is the classic choice for this casserole. Its creamy and slightly stretchy texture melts beautifully and adds richness to the dish. Use fresh mozzarella for the best results.

Parmesan cheese

Parmesan cheese adds a nutty and salty flavor to the casserole. It complements the other cheeses and brings out the savory notes of the dish. Grate the cheese fresh for maximum flavor.


Breadcrumbs are used to add a crispy and crunchy texture to the casserole. They also help to absorb any excess moisture in the dish. You can use plain breadcrumbs or seasoned ones, depending on your preference.

Fresh basil

Fresh basil is the finishing touch that adds a burst of freshness to the casserole. Its aromatic and slightly peppery flavor complements the other ingredients perfectly. Use it as a garnish just before serving.


Preparing the vegetables

Start by washing the eggplant and zucchini under running water and patting them dry. Then, remove the ends of the eggplant and zucchini and cut them into thin slices, about 1/4 inch thick. Sprinkle salt on the slices and let them sit for about 30 minutes to draw out any excess moisture.

Roasting the vegetables

Preheat your oven to 400°F (200°C). After the eggplant and zucchini have rested, rinse them under cold water and pat them dry. Brush both sides of the slices with olive oil and arrange them in a single layer on a baking sheet. Roast the vegetables in the preheated oven for about 20 minutes, or until they become tender and slightly golden brown.

Making the sauce

While the vegetables are roasting, you can prepare the tomato sauce. Heat some olive oil in a saucepan over medium heat. Add chopped onion and minced garlic, and sauté until they become translucent and fragrant. Pour in the tomato sauce and let it simmer for about 10 minutes, allowing the flavors to meld together.

Assembling the casserole

In a baking dish, start by spreading a layer of tomato sauce on the bottom. Then, arrange a layer of roasted eggplant and zucchini slices on top. Sprinkle some grated Parmesan and shredded mozzarella cheese over the vegetables. Repeat the layers until all the ingredients are used, ending with a layer of cheese on top.

Baking the casserole

Cover the baking dish with aluminum foil and place it in a preheated oven at 375°F (190°C). Bake the casserole for about 25-30 minutes, or until the cheese is melted and bubbly. Remove the foil and continue baking for another 10 minutes, or until the top becomes golden brown.

Garnishing and serving

Once the casserole is out of the oven, let it cool for a few minutes. Garnish with fresh basil leaves and a sprinkle of breadcrumbs for added texture. Serve the casserole warm, and enjoy the delicious combination of flavors and textures.


Adding protein

To make the casserole more substantial, you can add protein such as cooked ground meat, grilled chicken, or diced tofu. Simply layer the protein between the vegetable layers before baking.

Adding different herbs

If you want to experiment with different flavors, you can add other herbs to the tomato sauce. Try adding oregano, thyme, or rosemary for a Mediterranean twist. You can also sprinkle fresh parsley or cilantro on top of the casserole for added freshness.

Making it vegan

To make this casserole vegan-friendly, simply omit the cheese and use a vegan-friendly tomato sauce. You can also use nutritional yeast in place of the Parmesan cheese for a cheesy flavor.

Using different cheeses

While mozzarella and Parmesan are the traditional choices, you can also use other types of cheese in this casserole. Try using cheddar, Gruyère, or even feta for a different taste. Experiment with different combinations to find your favorite.

Adding other vegetables

Feel free to get creative and add other vegetables to the casserole. Bell peppers, mushrooms, or spinach would make great additions. Just make sure to adjust the cooking time accordingly to ensure all the vegetables are cooked through.


Choosing the right eggplant and zucchini

Look for eggplants that are firm and shiny, with a deep purple color. Avoid eggplants with blemishes or soft spots. For zucchini, choose ones that are plump and have a bright green color. Avoid zucchini that is soft or wrinkled.

Getting rid of excess moisture

Drawing out excess moisture from the eggplant and zucchini slices before roasting is essential to prevent the casserole from becoming watery. Sprinkling salt on the slices and letting them sit for about 30 minutes helps to remove the excess moisture. Remember to rinse the slices after they have rested.

Adding a layer of flavor

Sautéing the onion and garlic before adding the tomato sauce adds depth and richness to the dish. This step helps to release the flavors of the onion and garlic, enhancing the overall taste of the casserole.

Adjusting the cooking time

Baking time can vary depending on the thickness of the vegetable slices and the type of oven you have. Keep an eye on the casserole while it’s baking and adjust the cooking time as needed. The cheese should be melted and bubbly, and the top should be golden brown.

Using leftovers

Leftover casserole can be stored in the refrigerator for up to 3 days. Simply cover the dish with plastic wrap or transfer the leftovers to an airtight container. The casserole can be reheated in the oven or microwave. It’s a delicious and convenient option for quick meals throughout the week.
