What Ingredients are in Crispy Parmesan Zucchini Casserole?
This Crispy Parmesan Zucchini Casserole relies on simple, everyday ingredients that come together to create something truly magical in the oven. The star of the show is obviously zucchini, which transforms from a humble summer squash into a mouthwatering side dish that might just steal the spotlight from your main course.
What makes this recipe so approachable is that you probably have most of these ingredients in your pantry already.
- 8-10 medium zucchini
- 1 cup Italian seasoned breadcrumbs
- 1/2 cup parmesan cheese
- 1/2 cup melted butter
- 1/2 teaspoon salt
- 1/2 teaspoon pepper
- 2 garlic cloves, chopped
When shopping for ingredients, look for firm, medium-sized zucchini without any soft spots. They’ll hold up better during baking than the giant ones, which can become watery.
And while pre-grated parmesan works fine in this recipe, grating your own from a block will give you an even meltier, more flavorful topping. Not a garlic fan? You could reduce the amount or substitute with a pinch of garlic powder instead.
The beauty of this recipe is its flexibility—it welcomes small tweaks based on your personal preferences.
How to Make this Crispy Parmesan Zucchini Casserole
Making this zucchini casserole couldn’t be simpler, and the results are absolutely worth the minimal effort. Start by preheating your oven to 350°F and greasing a baking dish—this prevents sticking and makes cleanup a breeze.
Take your 8-10 medium zucchini and slice them into even rounds, arranging them in a single layer in your prepared baking dish. This single layer is essential for achieving that perfect texture—pile them too high and you’ll end up with soggy zucchini instead of crispy perfection.
Once your zucchini is arranged, sprinkle it evenly with 1/2 teaspoon salt, 1/2 teaspoon pepper, and 2 chopped garlic cloves.
In a separate bowl, combine 1 cup of Italian seasoned breadcrumbs with 1/2 cup parmesan cheese, mixing them thoroughly. This breadcrumb-cheese mixture is what creates that irresistible golden crust we’re aiming for.
Spread this mixture evenly over your seasoned zucchini, making sure to cover it completely. Now comes the magic touch—drizzle 1/2 cup of melted butter over the entire dish. The butter helps the topping crisp up beautifully while adding rich flavor.
Cover the dish with foil (this helps steam the zucchini initially) and pop it into your preheated oven for about 45 minutes. If you want an extra-crispy top, consider removing the foil for the last 10-15 minutes of baking.
You’ll know it’s ready when the zucchini is tender when pierced with a fork and the topping has turned a gorgeous golden brown. Let it rest for about 5 minutes before serving—this helps the flavors settle and prevents burned mouths, which is always a plus when you’re as impatient to dig in as I am!

What to Serve with Crispy Parmesan Zucchini Casserole

I find this Italian-style side pairs wonderfully with grilled chicken, roasted salmon, or even a classic meatloaf.
For a complete Italian dinner, why not serve it alongside spaghetti with marinara? The acidity from the tomato sauce perfectly cuts through the buttery, cheesy goodness of the zucchini.
