These baked Parmesan summer veggies are wonderfully simple: zucchini, yellow squash, and small tomatoes roasted together and topped with a thin layer of Parmesan that melts into a golden, savory crust. It’s a genuinely easy way to make the most of summer produce, and the combination of tender roasted vegetables and melty, slightly crisped cheese is nothing short of addictive. With just a handful of ingredients and about 25 minutes, this is the kind of side dish that comes together quickly enough for a weeknight but tastes special enough for company.
What makes this dish so appealing is how little it asks of you for how much flavor it delivers. The vegetables roast at high heat until tender, while a thin layer of Parmesan on each piece melts and browns into a savory, golden topping. There’s no sauce to make and no complicated technique, just good summer vegetables, a sprinkle of seasoning, and cheese, baked until everything is perfectly tender and golden.
Why this works
A few simple things are what make these veggies so good, and they’re worth understanding.
High heat roasting is what gives the vegetables great texture. Roasting at 425°F cooks the zucchini, squash, and tomatoes quickly, so they turn tender without becoming mushy or watery, and it’s also hot enough to properly melt and brown the Parmesan on top in the same amount of time. This higher temperature is really doing double duty, cooking the vegetables through and browning the cheese in a single, relatively short bake.
Arranging the vegetables in a single layer helps everything cook evenly. Spreading the zucchini and squash rounds out with the tomato halves tucked into the gaps means every piece gets direct contact with the hot pan and oven heat, so nothing steams or cooks unevenly in a crowded pile of overlapping vegetables.
A thin layer of Parmesan on each piece is the key topping technique. Spooning just a thin layer of Parmesan onto each vegetable (rather than a thick mound) lets it melt and turn golden brown evenly across the whole pan, giving every bite that same delicious, cheesy, slightly crisp topping. A thick clump, by contrast, tends to melt unevenly and can end up greasy in spots and dry in others.
And watching the bake time closely (or finishing under the broiler) ensures perfect browning. Since ovens vary, keeping an eye on the vegetables and pulling them as soon as the Parmesan turns light golden brown prevents overcooking, and a quick minute or two under the broiler at the end can speed up that browning if needed, especially in an oven that runs a little cool.
What goes in
The ingredient list is short and simple.
You’ll need a zucchini, a yellow summer squash, a pint of small tomatoes, garlic salt and freshly ground black pepper, and freshly grated Parmesan cheese.
A few notes. Cut the zucchini and squash into ¼-inch-thick slices so they cook evenly. Use small tomatoes (like cherry or grape tomatoes), halved, cut side up, so they roast nicely without falling apart. Use freshly grated Parmesan, rather than pre-shredded, for the best melt and browning. And this is a great way to use up a summer garden or farmers market haul.
How to make it
Place an oven rack in the center position and preheat the oven to 425°F. Line a baking sheet with foil (lightly misted with nonstick spray) or parchment paper.
Wash and dry the zucchini and squash, then cut each into ¼-inch-thick slices. Arrange the zucchini and squash rounds evenly on the prepared pan. Wash, dry, and halve the tomatoes, and place them cut side up in the empty spaces between the zucchini and squash.
Lightly sprinkle the vegetables with garlic salt and black pepper. Use a small spoon to spread a thin layer of Parmesan on each piece of vegetable.
Bake for 15 to 20 minutes, until the Parmesan melts and turns light golden brown. Watch closely the first time you make these, and pull them early if the cheese browns before 15 minutes; alternatively, broil for a minute or two at the end to speed up browning. Serve immediately.
Tips, serving, and storing
A few things help. Slice the zucchini and squash evenly so they cook at the same rate. Spread just a thin layer of Parmesan on each piece rather than a thick mound, for the most even browning. Watch closely near the end of baking, since ovens vary and Parmesan can go from golden to burnt quickly. And serve immediately, while the cheese is still melty and the vegetables are hot.
A couple more. If you want extra browning, a quick minute or two under the broiler at the end does the trick, just watch it closely so it doesn’t scorch. And feel free to season with a pinch of Italian herbs or a sprinkle of red pepper flakes if you’d like extra flavor.
These veggies make a wonderful side dish for grilled chicken, steak, fish, or burgers, and they’re a great way to use up an abundance of summer produce. Serve them hot, right out of the oven, alongside almost any main dish. They’re light enough to pair with something rich, and flavorful enough to stand on their own as a light vegetarian meal too.
For storing, keep leftovers in an airtight container in the fridge for up to 3 days. Reheat in the oven or a skillet to help the cheese and vegetables regain some of their texture (the microwave will soften them further and make the topping less appealing). These are best fresh, since the cheese topping loses some of its appeal once reheated, but leftovers are still tasty.
This makes about 3 to 4 servings. Simple, cheesy, and full of summer vegetable flavor, these baked Parmesan summer veggies are a genuinely addictive side dish, and they’re a great way to turn a handful of garden vegetables into something you’ll want to make again and again. It’s proof that a side dish doesn’t need many ingredients or much effort to end up as the thing everyone reaches for seconds of.
