Whether you are swimming in summer zucchini or just craving an easy comfort food, this irresistible baked zucchini cheese recipe became my go-to when I wanted something a little lighter than the standard potato gratin but with all the cheesy satisfaction.
I first baked this on a busy weeknight with a pile of zucchini that needed using and now it is a must whenever friends drop by for supper. Even picky eaters go back for seconds because it truly does not feel like eating vegetables.
Ingredients
- Zucchini: sliced thinly brings a mild taste and tender bite. Pick firm zucchini with shiny skin and no soft spots
- Fresh garlic: minced is essential for a savory background flavor. Use plump cloves and crush them right before adding for best aroma
- Olive oil: keeps the zucchini luscious and helps crisp up the topping. Go for extra virgin for the deepest flavor
- Salt and black pepper: bring balance and brightness. Use flaky sea salt and freshly cracked pepper if possible
- Cheddar cheese: shredded adds richness and gooey texture. A sharp cheddar is best for big flavor
- Parmesan cheese: grated provides a salty nutty accent. Always use real Parmigiano Reggiano if you can for the ultimate taste
- Breadcrumbs: create that signature crispy crust. Use fresh or panko for extra crunch
Instructions
- Prep the Oven and Baking Dish:
- Heat your oven to 190°C. Make sure the oven rack is in the center so your cheese gets bubbly and brown. Grease a baking dish lightly with olive oil or use a nonstick spray so nothing sticks
- Season the Zucchini:
- Place all your sliced zucchini into a big bowl. Add the minced garlic, drizzle with olive oil and sprinkle on the salt and black pepper. Toss everything with your hands until every slice looks glossy and coated
- Layer in the Baking Dish:
- Spread the seasoned zucchini slices in an even layer in your prepared baking dish. Try not to overlap them too much for even cooking and browning
- Add Cheese and Breadcrumb Topping:
- Sprinkle the shredded cheddar all over, followed by the grated Parmesan. Then cover everything generously with breadcrumbs. The cheeses melt into the zucchini and the breadcrumbs turn beautifully golden
- Bake to Perfection:
- Slide the dish into the hot oven. Bake for 25 to 30 minutes. The zucchini will soften and the top will be deeply golden and crisp. If the top looks pale at the end, let it go another couple minutes
- Let Cool and Serve:
- Take your bubbling cheesy zucchini out and let it rest a few minutes before serving. That way the cheese sets a bit and slicing is clean

Cheddar is the star here. It turns molten and stretches beautifully. Plus the combo with Parmesan gives everything a little salty kick. My family once fought over the last piece and now I always double the recipe on holidays.
Storage Tips
This dish keeps well in the fridge for up to three days. Let it cool completely then cover tightly with foil or transfer to an airtight container. Reheat in the oven for best texture so the topping gets crispy again.
Ingredient Substitutions
If you do not have cheddar, try mozzarella or fontina for extra melt. You can swap out Parmesan for Grana Padano or pecorino. If you need it gluten free, use gluten free panko or crushed cornflakes for the topping.
Serving Suggestions
Serve warm as a side to roast chicken, steak, or fish. It can also stand alone as a main with tomato salad or sautéed greens. For brunch, I sometimes tuck leftovers into a toasted sandwich.
Cultural Context
Baked vegetable casseroles like this one are staples in Mediterranean homes. This recipe nods to Italian traditions where Parmesan and olive oil shine alongside fresh produce.
Seasonal Adaptations
Replace half the zucchini with yellow squash for a hint of sweetness in early summer. Add thin slices of tomato under the cheese layer in late summer for more color and tang. Sprinkle with fresh basil or thyme before serving for garden fragrance.
Success Stories
I have made this at least a dozen times for potlucks and there are never leftovers. Kids eat it without a fuss and grownups rave about the cheesy crust. I even took it to a neighbor who came home from the hospital and she asked for the recipe the next day.
Freezer Meal Conversion
You can assemble the entire dish ahead of time then freeze before baking. Thaw overnight and bake as directed, or bake straight from frozen covered in foil for the first fifteen minutes. It is a lifesaver for busy weeks or new moms.

This easy dish makes its way to our table all summer long. Once you taste that cheesy golden top, you will crave zucchini season all year.
