This baked Italian zucchini is baked in the oven with the most delicious tomato sauce and cheese until bubbly and delicious. It is a quick meal that anyone can make and a zucchini recipe that everyone will love.

Italian Baked Zucchini is a delicious way to make zucchini as a main dish (or side dish) and definitely a zucchini recipe to keep in your repertoire. This Italian zucchini is basically a baked zucchini parmesan but without the breading and my favorite zucchini recipe to make.
I actually began making this recipe as a way to use up zucchini in my garden which I do grow a lot of. Since my family grew tired of eating so much zucchini, I needed to figure out a recipe that would get them excited to eat it so I turned to my Italian background and made came up with this recipe.
This Italian zucchini recipe is a great main dish because it gives zucchini a star role on your table. Italians like myself, love making baked vegetables with tomatoes and cheese and this baked zucchini is no exception.
What You Will Need
There are only a few ingredients you need to make this recipe (full list below):
- Zucchini
- Fresh mozzarella: Try to use fresh if you can but shredded will work too
- Marinara sauce: This is my homemade quick marinara (see below for the recipe) or you can use jarred sauce.
- Olive oil
- Kosher salt and pepper
- Parmesan
How To Make Baked Italian Zucchini
Making this recipe is mostly assembling and a little prep. Here are the steps:

- Pre-cook zucchini: This starts the cooking process for this zucchini since it doesn't spend too much time in the oven later on. You can grill (or pan-fry) your zucchini strips in a little extra virgin olive oil. You also want to preheat the oven.
- Add zucchini to baking dish: Once you have cooked your zucchini, the next step is placing it in a baking dish or baking sheet. Only one layer!
- Add marinara: Now you start adding your marinara sauce. Remember, this is not lasagna so you are only making a single layer of zucchini as the base.
- Top with cheese: Once you get your marinara sauce on the zucchini, you are going to add your mozzarella and grated Parmesan cheese. It looks like a mess but it will come out beautiful once all the cheese has melted during baking.
- Bake: After all of your ingredients are added to your zucchini, just place it in a preheated oven until the cheese is melted and bubbly, about 5 minutes. You can also bake it for 15 minutes or until the cheese is melted.

As you can see from the pictures above, this baked zucchini will start off looking a little messy when you are prepping and assembling everything. Once this goes into the oven, the cheese that melts over everything will bring it all together and it ends up looking beautiful and delicious.
For me, that makes this meal a great one for entertaining or for a special dinner for family. It is also great for those who are looking for those on a gluten-free diet. Really, any dish that is served with hot bubbling cheese will always be a winner and popular with almost everyone.
Variations
This Italian zucchini can be made just as is (my favorite) or jazzed up with different ingredients. Here are some ideas for you:
- Add meat: If you have meat eaters in your house go ahead and add ground beef, Italian sausage or even ground turkey to the sauce. Pepperoni on top is really good too!
- Add in more veggies: sliced eggplant, yellow squash, and bell peppers are all good additions to this baked zucchini.
Faqs
No, zucchini is not bitter like eggplant that many people are familiar with salting before cooking with it. Just prepare your zucchini the same way you would other vegetables. No special treatment is needed.
To prevent the zucchini from getting soggy, make sure to not overcook it. Cooking the zucchini on a medium-high for a shorter time will cook the zucchini until golden brown on the outside and ensure the zucchini will stay firm.
Storage & Reheating Instructions
This baked Italian zucchini stores really well. After cooking, allow the zucchini to completely cool then place in an air-tight container in the fridge for up to 2 days. To reheat, place the zucchini in an oven-safe dish and heat in a preheated 350-degree oven for 10-15 minutes or until heated all the way through.
