How to Make Easy Oven-Roasted Zucchini, Squash, and Tomatoes with Parmesan Recipe
Step 1: Get Your Oven Ready
Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper. This step ensures your veggies cook evenly without sticking, setting you up for perfectly roasted goodness.
Step 2: Toss Your Veggies
In a large bowl, combine the zucchini, yellow squash, and halved tomatoes. Tossing them together lets you evenly coat every piece with flavor in the next step.
Step 3: Add Flavor and Oil
Drizzle the olive oil over the veggies, then add the minced garlic, salt, black pepper, and Italian seasoning if using. Toss well until everything is nicely coated—this flavorful oil blend is what creates that irresistible roasted crust.
Step 4: Prepare for Roasting
Spread the vegetables out in a single layer on the parchment-lined baking sheet. Giving them space is essential for even roasting and browning, so avoid overcrowding.
Step 5: Roast to Perfection
Place the baking sheet in the oven and roast the veggies for 15 to 20 minutes. About halfway through, give them a gentle stir to ensure even cooking. You’ll want to see tender, slightly golden vegetables by the end of this step.
Step 6: Sprinkle Parmesan
Remove the sheet from the oven and generously sprinkle freshly grated Parmesan all over the roasted veggies. This step is where the magic happens—cheese meets warm veggies creating an irresistible crust.
Step 7: Melt and Brown the Cheese
Pop the baking sheet back into the oven for another 3 to 5 minutes. Watch closely as the Parmesan melts and forms a light golden brown, bringing a wonderful savory depth to the dish.
Step 8: Garnish and Serve
Finish with a sprinkle of fresh chopped basil or parsley for a splash of color and a bright, herbaceous lift that complements the rich Parmesan and roasted vegetables perfectly.

Make Ahead and Storage
Storing Leftovers
You can store any leftovers in an airtight container in the refrigerator for up to 3 days. The flavors actually deepen after resting, though it’s best enjoyed within this short window for optimal texture and freshness.
Freezing
While roasting vegetables is best fresh, if you need to freeze leftovers, allow them to cool completely, then place in an airtight freezer-safe container. Use within 1 month, though keep in mind the texture may soften after thawing.
Reheating
To reheat, place the veggies on a baking sheet and warm in a 350°F (175°C) oven for about 10 minutes to revive their roasted charm. Avoid microwaving, which can make the veggies soggy.
FAQs
Can I use other vegetables besides zucchini and squash?
Absolutely! Feel free to add bell peppers, eggplant, or mushrooms for a hearty variation. Just adjust the roasting time as needed since different vegetables cook at different rates.
Is Parmesan essential for this recipe?
Parmesan adds a nutty, salty crust that really ties the dish together, but you can skip it if you want a dairy-free option. Nutritional yeast works well as a cheesy substitute.
Can I prepare this dish without garlic?
Yes, though garlic adds a fantastic aroma and depth. You can omit it or substitute with garlic powder if you prefer a milder hint of flavor.
What if I don’t have Italian seasoning?
No worries! You can use a mix of your favorite dried herbs like oregano, thyme, or rosemary. The Italian seasoning is just a convenient blend that brightens the dish.
Can this be made ahead of time?
You can prep and toss the vegetables with oil and seasonings a few hours ahead, then roast right before serving to keep them fresh and vibrant.
