Position a rack in the center of your oven and preheat to 400°F (200°C). Line a large rimmed baking sheet with parchment paper or aluminum foil for easy cleanup. The high temperature will help caramelize the vegetables and create a crispy cheese topping.

In a small bowl, combine the olive oil, minced garlic, and Italian seasoning. Stir well and let the mixture sit for 5-10 minutes. This resting time allows the garlic and herbs to infuse the oil with their flavors, creating a more aromatic base for your vegetables.

Place the sliced zucchini, yellow squash, and halved tomatoes in a large mixing bowl. Pour the garlic-infused oil mixture over the vegetables. Using clean hands or a gentle tossing motion with two large spoons, coat all the vegetables evenly with the seasoned oil. Make sure each piece gets a light coating for maximum flavor.

Transfer the seasoned vegetables to your prepared baking sheet, arranging them in a single layer with minimal overlap. Try to distribute the tomatoes evenly throughout. Season generously with salt and freshly ground black pepper, keeping in mind that the Parmesan will add saltiness as well.
05 -
Sprinkle the shredded Parmesan cheese evenly over the arranged vegetables. Place the baking sheet in the preheated oven and roast for 25-30 minutes, or until the vegetables are tender when pierced with a fork. The cheese should be melted and golden brown with some crispy edges forming.

For extra browning, you can switch your oven to broil for the final 2-3 minutes, watching carefully to prevent burning. Remove from the oven and let rest for about 2 minutes. Sprinkle with fresh or dried parsley for a pop of color and fresh flavor. Serve immediately while still warm and the cheese is at its most delicious.
