Ingredients for Roasted Garlic-Parmesan Zucchini, Squash, and Tomatoes

Ingredients:

Two small zucchini (about 1 lb total), sliced 1/2-inch thick
Two small yellow squash (about 1 lb total), sliced 1/2-inch thick
14 ounces small Campari or Flavorino tomatoes, halved
3 tablespoons olive oil
4 garlic cloves, minced (about 1 1/2 tablespoons)
1 1/4 teaspoons Italian seasoning
Salt and freshly ground black pepper, to taste
1 cup finely shredded Parmesan cheese (about 2.4 ounces)
Fresh or dried parsley, for garnish (optional)

Optional substitutions

Use a vegan Parmesan alternative to make the dish dairy-free.
For a lower-fat version, halve the olive oil and reduce the cheese.

How to Make Roasted Garlic-Parmesan Zucchini, Squash, and Tomatoes – Step by Step

Step 1: Preheat the oven

Preheat the oven to 400°F (200°C). Line an 18 x 13-inch rimmed baking sheet with parchment paper or aluminum foil for easy cleanup.

Step 2: Make the seasoned oil

In a small bowl, mix the olive oil, minced garlic, and Italian seasoning. Let the mixture rest for 5–10 minutes so the garlic flavor infuses into the oil.

Step 3: Prepare the vegetables

Combine the zucchini, yellow squash, and halved tomatoes in a large bowl. Drizzle with the seasoned oil and gently toss to coat each piece evenly. Season lightly with salt and pepper.

Step 4: Arrange for roasting

Spread the vegetables in a single layer on the prepared baking sheet. Avoid crowding to ensure they roast rather than steam; leave a little space between pieces for best caramelization.

Step 5: Add cheese and roast

Sprinkle the shredded Parmesan evenly over the vegetables. Roast in the preheated oven for 25–30 minutes, or until the vegetables are tender and the cheese is golden and slightly crisp along the edges. If you like more browning, switch to the oven’s broil setting for 1–2 minutes—watch closely to prevent burning.

Step 6: Garnish and serve

Remove from the oven and let the vegetables rest a couple of minutes. Garnish with chopped parsley if desired, then serve warm as a side or part of a main course.

Helpful tips

Choose fresh produce: Firm, seasonal zucchini, squash, and ripe tomatoes yield the best texture and flavor.
Prevent sogginess: Give the vegetables room on the pan and roast at a high enough temperature so they brown instead of releasing too much moisture.
Adjust cheese timing: For a crisper topping, add most of the Parmesan at the end of roasting or broil briefly. For a more integrated, melty finish, add it at the start.
Use convection if possible: A convection oven circulates hot air and helps crisp the edges of the vegetables.
Flip once: Turn the vegetables halfway through cooking for more even browning.

Serving suggestions

This roasted vegetable medley pairs wonderfully with grilled steak, roast chicken, or pan-seared fish. To make a vegetarian meal, serve over quinoa, couscous, or farro and add a drizzle of olive oil and a squeeze of lemon. The dish also complements fresh greens or a simple grain salad. A light white wine such as Sauvignon Blanc or Pinot Grigio pairs nicely, but water with lemon or iced tea are equally refreshing accompaniments.

Storage and reheating

Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in a 350°F oven until warmed through to refresh texture and re-crisp the cheese. The microwave will heat quickly but may soften the vegetables and toppings. Freezing is not recommended, as it can change the texture of the vegetables.

Frequently Asked Questions (FAQs)

Can I add other vegetables? Yes. Bell peppers, mushrooms, or thinly sliced carrots roast well with these ingredients. Adjust roasting time for denser vegetables.
Will pre-shredded Parmesan work? Yes, but freshly grated Parmesan melts and caramelizes more evenly and provides a fuller flavor.
How do I avoid watery tomatoes? Use smaller, firmer tomatoes like Campari or Flavorino. Halve them and spread cut-side up if you want to minimize juices on the pan.
How can I make it dairy-free? Replace the Parmesan with a vegan Parmesan-style product or sprinkle with nutritional yeast for a cheesy flavor.
