Ingredients

For this Roasted Garlic-Parmesan Zucchini, Squash and Tomatoes recipe, you’ll need:

• 2 medium zucchini (about 1 pound/450g), cut into 1/2-inch slices
• 2 medium yellow squash (about 1 pound/450g), cut into 1/2-inch slices
• 1 pint (2 cups/300g) cherry or grape tomatoes, halved
• 4 large garlic cloves, minced (about 2 tablespoons)
• 2 tablespoons olive oil
• 1 teaspoon dried Italian seasoning
• 1/2 teaspoon salt
• 1/4 teaspoon freshly ground black pepper
• 1/2 cup (50g) freshly grated Parmesan cheese
• 2 tablespoons fresh basil, chopped (for garnish)

Choose zucchini and squash that feel firm and heavy for their size. For the Parmesan, freshly grated delivers far superior flavor compared to pre-packaged varieties. The tomatoes should be ripe but firm to maintain their shape during roasting.

Pro Tips

Even Sizing Matters: Cut your zucchini and squash into uniform pieces to ensure they cook at the same rate. Vegetables of similar thickness will finish cooking simultaneously, preventing some pieces from becoming mushy while others remain undercooked in your vegetable parmesan bake.

Avoid Overcrowding: Use a large baking sheet or two smaller ones to give your vegetables plenty of space. Overcrowding causes steaming rather than roasting, robbing you of those deliciously caramelized edges that make roasted vegetables so irresistible. For the best roasted summer vegetables, they should be in a single layer with a bit of space between pieces.

Temperature is Key: Start with a fully preheated oven (425°F/220°C). This high heat quickly sears the outside of the vegetables, locking in moisture while creating those desirable browned edges. A cooler oven will result in softer, less caramelized vegetables, changing the character of your garlic Parmesan roasted vegetables entirely.

Instructions

Step 1: Preheat your oven to 425°F (220°C) and position a rack in the center. Line a large baking sheet with parchment paper or aluminum foil for easier cleanup.

Step 2: Prepare your vegetables. Slice the zucchini and yellow squash into 1/2-inch thick rounds. Halve the cherry tomatoes. Mince the garlic as finely as possible to ensure it distributes evenly throughout the dish.

Step 3: Place all the vegetables in a large mixing bowl. Drizzle with olive oil and sprinkle with garlic, Italian seasoning, salt, and pepper. Toss thoroughly to coat every piece. Make sure you’re getting all those fantastic flavors onto each vegetable.

Step 4: Arrange the seasoned vegetables on your prepared baking sheet in a single layer. For the best results with your Roasted Garlic-Parmesan Zucchini, Squash and Tomatoes, ensure the vegetables aren’t touching too much. This allows hot air to circulate around each piece, promoting even browning.

Step 5: Place the baking sheet in the preheated oven and roast for 15 minutes. The vegetables will begin to soften and release their juices.

Step 6: Remove the baking sheet from the oven and sprinkle the Parmesan cheese evenly over the vegetables. Return to the oven and continue roasting for another 5-7 minutes until the cheese is melted and beginning to turn golden in spots.

Step 7: For the finishing touch, scatter freshly chopped basil over the hot vegetables just before serving. The heat will release the aromatic oils in the basil, adding a wonderful fragrance to your perfectly roasted vegetables.

Variations

Mediterranean Style: Transform your Roasted Garlic-Parmesan Zucchini, Squash and Tomatoes by adding 1/2 cup pitted kalamata olives and 1/2 cup crumbled feta cheese instead of Parmesan. After roasting, drizzle with a tablespoon of balsamic glaze and sprinkle with fresh oregano for an instant trip to the Mediterranean coastline.

Spicy Kick Version: For those who enjoy heat, add 1/4 to 1/2 teaspoon of red pepper flakes to the seasoning mix before roasting. After cooking, finish with a sprinkle of smoked paprika and replace the Parmesan with pepper jack cheese for a bold flavor variation of zucchini squash tomato bake.

Herb Garden Harvest: Enhance the aromatic profile by incorporating a broader range of fresh herbs. Add 1 tablespoon each of fresh thyme, rosemary, and oregano along with the basil. This variation works particularly well when served alongside grilled meats or as part of an antipasto platter.

Storage and Serving

Roasted Garlic-Parmesan Zucchini, Squash and Tomatoes can be stored in an airtight container in the refrigerator for up to 3 days. The flavors actually develop nicely overnight, making this an excellent make-ahead side dish. Reheat in a 350°F (175°C) oven for about 10 minutes to restore some of the original texture, or microwave for 1-2 minutes if you’re in a hurry.

Serve these vibrant vegetables alongside grilled chicken or fish for a complete, healthy meal. They also make a wonderful addition to grain bowls – try them atop quinoa or farro with a dollop of hummus for a satisfying vegetarian main dish. For an elegant presentation, serve your roasted vegetable medley on a large platter with fresh herbs scattered on top and lemon wedges on the side for guests to brighten their portions as desired.

FAQs

Can I prepare this dish ahead of time?
You can slice all the vegetables up to a day in advance and store them in the refrigerator. For best results, wait to season and roast them until shortly before serving. The finished dish can be reheated but is most vibrant when freshly made.

How do I prevent my vegetables from becoming soggy?
Make sure not to overcrowd the baking sheet. Vegetables release moisture while cooking, and if they’re too close together, they’ll steam rather than roast. Also, higher temperature roasting (425°F) helps evaporate moisture quickly.

Can I use different vegetables in this recipe?
Absolutely! Bell peppers, eggplant, or red onion would work beautifully in this Roasted Garlic-Parmesan Zucchini, Squash and Tomatoes recipe. Just make sure to adjust cooking times for denser vegetables.

Is this dish keto-friendly?
Yes, this recipe is excellent for keto diets. Zucchini, squash, tomatoes, garlic, olive oil, and Parmesan are all low in carbohydrates and keto-approved.

Can I use dried basil instead of fresh?
While fresh basil provides the best flavor, you can substitute 1 teaspoon of dried basil added with the other seasonings before roasting. Fresh herbs are always added at the end, while dried herbs benefit from the entire cooking process.
