Italian Zucchini Casserole Ingredients
For the Vegetables
- Large Slicing Tomatoes – Adds juiciness and acidity; substitute with Roma or heirloom tomatoes for a richer flavor.
- Medium Zucchini – Main ingredient that provides bulk and texture; yellow squash works beautifully as a substitute for variety.
- Large Onions – Contributes sweetness and depth; consider shallots for a milder flavor.
For Seasoning

- Sicilian Oregano – Adds an aromatic punch; swap with Italian seasoning if you’re in a pinch.
- Crushed Hot Red Pepper Flakes – Introduces a subtle heat; omit for a milder flavor if preferred.
- Garlic – Enhances the aroma and taste of the casserole; freshly minced is best, though garlic powder can be used in a pinch.
For the Topping
- Pecorino Romano Cheese – Provides a salty, cheesy flavor and helps bind the layers; Parmesan is a great alternative.
- Extra Virgin Olive Oil – Adds richness and moisture; you can replace it with a lighter oil like avocado oil.

How to Make Italian Zucchini Casserole
-
Preheat the oven to 375°F and grease a 9×13 baking dish with a bit of olive oil to prevent sticking. This foundational step ensures that your casserole bakes evenly and doesn’t stick.
-
Mix the breadcrumb topping by combining plain breadcrumbs, Sicilian oregano, grated Pecorino Romano cheese, crushed hot red pepper flakes, minced garlic, and a drizzle of olive oil in a mixing bowl. Stir until the breadcrumbs are well-coated and fragrant.
-
Slice the zucchini, tomatoes, and onions thinly using a mandoline or a sharp knife. Drain the tomatoes and pat both the zucchini and tomatoes dry with paper towels to absorb excess moisture before layering them. This will prevent your casserole from becoming soggy.
-
Layer the zucchini slices in the bottom of the prepared dish, drizzling each layer with olive oil and seasoning with salt, pepper, oregano, and grated cheese. Repeat this layering process with the onions and tomatoes until all vegetables are used.
-
Top the layered veggies with the breadcrumb mixture, making sure to moisten them with a bit more olive oil for a golden, crunchy finish. Spread it evenly over the surface for the best results.
-
Bake the casserole uncovered for about 45 minutes or until it’s bubbling and most of the liquid has evaporated. If needed, broil for 1-2 more minutes for a beautiful golden crust on top.
-
Cool the casserole for 10-15 minutes before serving. This allows the flavors to settle and makes it easier to cut when serving.
Optional: Drizzle with a touch more olive oil just before serving for added richness.

What’s the best way to store leftovers?
I recommend placing your Italian Zucchini Casserole in an airtight container and storing it in the refrigerator. It will keep for up to 3 days, allowing you to enjoy those delightful flavors for another meal.
Can I freeze Italian Zucchini Casserole?
Yes, you can! To freeze, allow the casserole to cool completely. Then, wrap it tightly in plastic wrap and aluminum foil or place it in a freezer-safe container. It can last up to 3 months. When you’re ready to enjoy it again, let it thaw overnight in the fridge and reheat in the oven.
What if my casserole turns out soggy?
Very good question! If that happens, it’s often due to excess moisture from the vegetables. Be sure to pat the zucchini and tomatoes dry before layering, and drain the tomatoes well. If your casserole still comes out watery, you can bake it a little longer without covering it to allow excess liquid to evaporate.

The more the merrier! You can easily substitute the plain breadcrumbs with gluten-free breadcrumbs. Additionally, just check that your cheese and other ingredients are labeled gluten-free, and you’ll have a deliciously safe meal for everyone.
