This cheesy baked zucchini casserole is one of those happy solutions to bumper crops or extra veggies in the fridge It comes out bubbly and golden with irresistibly crisp breadcrumbs and a duo of cheeses that melds into the tender zucchini slices The garlic and olive oil coax out a savory robust flavor you just cannot get from steaming or sautéing After one try it quickly joined our summer dinner rotation and I love how the recipe works as a side or a light main
My family loves the aroma of this dish as it bakes It is always one of the first to disappear from the table and I usually sneak extras for lunch the next day
Ingredients
- Zucchini: medium size for the right slice to texture ratio look for firm unblemished skin bright and free of mold spots for best results
- Garlic: fresh cloves really bring depth and warmth chopped or pressed so the flavor spreads evenly
- Olive oil: choose extra virgin for rich taste or regular for a milder note makes every bite saucy and helps with browning
- Salt: always taste as you go use flaky or kosher for best seasoning control
- Black pepper: always grind fresh to release its pungency which perks up the mellow zucchini
- Cheddar cheese: gives classic melt factor sharp or medium both work opt for block cheese to shred yourself for the creamiest result
- Parmesan cheese: adds a nutty crusty goodness grating it fresh just before baking gives the deepest flavor
- Breadcrumbs: create that signature golden topping go for fine fresh or quality storebought for best crunch
Instructions
- Prepare the Oven and Baking Dish:
- Set your oven to 190 degrees Celsius to preheat Lightly coat a baking dish with olive oil using a brush or paper towel which helps prevent sticking and encourages browning
- Season the Zucchini:
- Slice zucchini evenly to ensure even cooking Place slices in a large bowl Add your minced garlic olive oil salt and pepper Toss with clean hands or tongs so that every piece gets coated for uniform flavor throughout
- Arrange in Baking Dish:
- Spread the coated zucchini in a single even layer in your baking dish Try not to overlap much so every slice gets some direct heat and turns tender without becoming too soft
- Add Cheese and Top:
- Distribute the shredded cheddar over the zucchini then sprinkle the freshly grated Parmesan on top Finish with an even layer of breadcrumbs pressing lightly so they stick to the cheese for your crispy topping
- Bake to Perfection:
- Slide the dish onto the middle rack Bake uncovered for 25 to 30 minutes The cheese should be bubbling and the breadcrumbs golden brown If your top is not crisp enough set the dish under the broiler for an extra minute or two
- Rest and Serve:
- Let the casserole cool for a few minutes before using a spatula to serve Cooling just a bit firms everything up so you get neat slices and all that gooey cheese stays where it should

Zucchini is my favorite for these kinds of bakes because it is mild yet soaks up all the other savory flavors I still remember my little one helping sprinkle the cheese and giggling at how stretchy it got once hot from the oven those moments make this recipe extra special
