How to Make Roasted Garlic Parmesan Zucchini, Squash, and Tomatoes :

Begins by preheating the oven and preparing a baking tray with parchment paper or light greasing. The vegetables are washed, then zucchini and yellow squash are sliced into even rounds while the tomatoes are left whole to keep them juicy.

Next, all the vegetables are combined in a bowl and tossed with olive oil, garlic, salt, pepper, and Italian seasoning until evenly coated. They are then spread out on the tray in a single layer so they roast properly instead of steaming.

The vegetables are roasted in the oven, with a gentle stir halfway through to help them brown evenly. They are cooked until tender and slightly golden at the edges.

Finally, the roasted vegetables are removed from the oven and topped with Parmesan cheese so it melts slightly. They are finished with fresh parsley if desired and served warm.
