The Essential Ingredients for Success
Zucchini: You will need 2 medium zucchini, sliced into 1/2-inch (1.25cm) rounds. Look for firm skins to ensure they hold up under the heat.
Yellow Summer Squash: 2 medium yellow squash provide a beautiful color contrast. Like the zucchini, these roasted yellow squash coins should be uniform in thickness.
Parmesan Cheese: Use 1/2 cup (50g) of finely shredded parmesan. This is what creates that thick, golden-brown, bubbly parmesan cheese crust seen in the photos.
Extra Virgin Olive Oil: 2 tablespoons (30ml) are essential for achieving that olive oil sheen and promoting the charred vegetable edges.
Garlic: 3 cloves of minced garlic. These turn into tiny bits of toasted minced garlic during the roasting process, adding a deep umami flavor.
Seasoning Trio: A combination of 1/2 teaspoon (3g) sea salt, 1/2 teaspoon (1g) cracked black pepper, and 1/2 teaspoon (0.5g) dried parsley flakes for the perfect finish.
How to Make The Best Oven Roasted Zucchini and Squash
1. Preparing for Maximum Crunch
Preheat your oven to 425°F (220°C). A high temperature is non-negotiable for achieving charred vegetable edges without the vegetables becoming mushy.
Line a dark, rustic slate sheet pan or a heavy-duty baking sheet with parchment paper. Using a dark pan helps absorb more heat, leading to better caramelized zucchini rounds.
2. The Seasoning Technique
In a large mixing bowl, toss your zucchini and squash rounds with the olive oil until they have a glistening olive oil sheen. Add the minced roasted garlic bits, salt, and cracked black pepper.

3. Achieving the Toasted Parmesan Crust
Arrange the vegetables in a single layer on the sheet pan. Do not overlap them, or they will steam instead of roast. Sprinkle the finely shredded parmesan cheese generously over each round.
Ensure the cheese reaches the rims of the vegetables. This allows the cheese to melt down the sides and create those jagged, toasted edges that are highly visible in the macro photography.
4. Roasting to Golden Perfection
Roast for 15-20 minutes. You are looking for specific Visual & Sensory Cues: the cheese should be bubbly and golden-brown, and the vegetables should show slight caramelization and charred brown spots on the rims.
In the final 2 minutes, you can turn on the broiler for an extra-crispy, thick parmesan crust. Watch closely so the minced roasted garlic bits don’t burn.
5. The Final Flourish
Remove from the oven and immediately sprinkle with the very fine flakes of dried parsley. The residual heat will wake up the aroma of the herbs. Serve while the cheese is still visible crunch sharp.
Expert Tips for Non-Soggy Roasted Vegetables
- Salt at the End: If your vegetables tend to get watery, try salting them only after they come out of the oven, though seasoning during tossing is usually fine at 425°F.
- Uniform Slicing: Use a mandoline or a very sharp knife to ensure every round is the same thickness for even cooking.
- Avoid Overcrowding: If you have too many vegetables for one pan, use two. Airflow is the key to firm and dry textures.
- Pairing Suggestion: This side dish goes beautifully alongside our tender oven roasted asparagus for a full vegetable feast.
Storage, Reheating, and Freezing
Storage: Place leftovers in an airtight container in the refrigerator for up to 3 days. Note that the parmesan crust will lose some of its crunch over time.
Reheating: For best results, reheat in an air fryer or oven at 350°F (175°C) for 5 minutes. Avoid the microwave, as it will make the squash soggy.
Freezing: We do not recommend freezing this dish, as the cellular structure of the zucchini and squash will break down, resulting in a mushy texture upon thawing.
What to Serve With Oven Roasted Zucchini and Squash

Frequently Asked Questions
Yes! Bell peppers or red onions work well, but ensure they are cut into sizes that will cook in the same 15-20 minute window.
For the best ‘bubbly’ crust, use a block of parmesan and shred it finely yourself. Pre-grated cheese often contains anti-caking agents that prevent it from melting and crisping properly.
No, the skins are thin and edible. Keeping the skins on helps the rounds maintain their shape and adds a beautiful color contrast to the finished dish.
To prevent sogginess, roast the vegetables at a high temperature (425°F/220°C), avoid overcrowding the pan, and ensure they are sliced to a uniform 1/2-inch thickness.
Absolutely. Both zucchini and yellow squash are low-carb vegetables, and the parmesan cheese provides healthy fats and protein without adding carbs.
