Oven baked zucchini and cheese turns a pile of summer squash into a bubbly, golden side dish with very little work. Layers of tender slices, melted mozzarella, and a crunchy Parmesan crumb topping bake together in about twenty five minutes.
It works with almost any main course, and the oven does the hard part while you cook the rest of dinner. Leftovers reheat well, so it is a smart choice for busy weeknights and potlucks.

Why This Oven Baked Zucchini and Cheese Recipe Works
Slicing the squash into even rounds helps every piece soften at the same pace, so nothing turns mushy while the thicker slices stay firm.
Tossing the slices in olive oil and seasoning first builds flavor in every layer instead of only on the crumb topping.
The Parmesan and breadcrumb mix browns into a crisp lid, and the mozzarella underneath melts into stretchy pockets between the layers.
Ingredients for Oven Baked Zucchini and Cheese
- 4 medium zucchini, sliced into 1/4 inch rounds
- 2 tablespoons olive oil
- 1 clove garlic, minced
- 1 teaspoon dried oregano
- 1/4 teaspoon salt
- 1/4 teaspoon black pepper
- 1 cup shredded mozzarella cheese
- 1/2 cup grated Parmesan cheese
- 1/2 cup plain breadcrumbs
- Fresh basil leaves, for garnish
Zucchini. Choose firm, medium squash with shiny skin, because oversized ones hold more water and bake up soft and watery.
Cheese. Shred mozzarella from a block if you can, since it melts more smoothly than the bagged kind with anti caking coating.
Breadcrumbs. Plain dry breadcrumbs make a fine crust, and panko gives an even crunchier topping if you prefer.
Olive oil. Use a good everyday olive oil, because it coats the slices and helps the topping brown.
Seasoning. Salt is light here because the cheeses are salty, so taste a baked slice before adding more at the table.
How to Make Oven Baked Zucchini and Cheese
1. Heat and prep Heat the oven to 375 degrees F and grease a 9 by 13 inch baking dish, then slice the squash into even quarter inch rounds.
2. Season the slices Toss the rounds with olive oil, garlic, oregano, salt, and pepper in a large bowl until every slice looks glossy.
3. Mix the topping Stir the mozzarella, Parmesan, and breadcrumbs together in a second bowl so the cheese and crumbs spread evenly.
4. Build the first layer Arrange half of the slices in the dish with a slight overlap, then scatter half of the cheese mixture over the top.
5. Add the second layer Repeat with the remaining slices and finish with the rest of the topping, pressing lightly so the crumbs settle.
6. Bake until golden Bake on the middle rack for 20 to 25 minutes, until the squash is fork tender and the top is bubbly and browned.
7. Rest and garnish Let the dish stand for five minutes so the layers set, then scatter fresh basil over the top and serve.
How to Serve Oven Baked Zucchini and Cheese
Serve this dish hot beside grilled paprika chicken breast or oven baked garlic butter salmon for an easy dinner. A bowl of Italian house salad adds crunch, and creamy garlic Parmesan orzo turns the plate into a bigger meal.
How to Store and Reheat Oven Baked Zucchini and Cheese
Cool leftovers within two hours, then store them in an airtight container in the refrigerator for up to four days. Reheat portions in the oven at 350 degrees F until the center reaches 165 degrees F. The topping softens in the fridge, and the dish does not freeze well because the squash turns watery.
Tips and Variations for Oven Baked Zucchini and Cheese
Flag the allergens. This side contains milk and wheat, and some breadcrumbs include soy, so check labels when cooking for guests.
Dry the slices. If the rounds look wet after slicing, pat them with a clean towel so the dish bakes crisp instead of soggy.
Wash the squash. Rinse the skin under running water and scrub lightly before slicing, even though you plan to leave the peel on.
Keep slices even. Use a mandoline or a steady knife so the rounds stay about the same thickness and finish together.
Boost the crunch. Broil the dish for one to two minutes at the end and watch it closely so the crumbs brown without burning.
Try other herbs. Swap the oregano for Italian seasoning or fresh thyme if you want a different flavor.
Mix the squash. Replace one zucchini with yellow summer squash for a more colorful dish.
Check trusted guidance. For general advice on cooling and storing leftovers, see the University of Minnesota Extension guide to storing leftovers.
