Instructions
- Prepare the oven
Preheat oven to 425°F (220°C).
Line a large baking sheet with parchment paper or lightly grease it.
For better browning, use a large enough pan so the vegetables aren’t overcrowded. - Season the vegetables
Add zucchini, yellow squash, and tomatoes to a large bowl.
Add minced garlic, olive oil, Italian seasoning, oregano, red pepper flakes, salt, and black pepper.
Toss gently until everything is evenly coated. - Roast
Spread the vegetables in a single layer on the prepared baking sheet.
Roast for 15 minutes.
Remove from the oven and gently toss or turn the vegetables.
Sprinkle evenly with about ½ cup Parmesan.
Return to the oven and roast for another 8–12 minutes, until the vegetables are tender and the Parmesan is melted and lightly golden. - Add the finishing touch
If using the optional garlic butter, mix melted butter with grated garlic and 1 tbsp Parmesan.
Drizzle lightly over the hot roasted vegetables.
Sprinkle with the remaining Parmesan, fresh parsley, basil, and lemon zest. - Serve
Serve immediately while warm and cheesy. Add an extra sprinkle of Parmesan and freshly cracked black pepper just before serving.

Q&A
Q: Can I use frozen zucchini or squash?
A: Fresh vegetables are recommended because frozen zucchini and squash release more water and may become softer. If using frozen, thaw and drain very well first.
Q: How do I keep the vegetables from becoming watery?
A: Don’t overcrowd the baking sheet. Spread the vegetables in a single layer and roast at high heat. This allows excess moisture to evaporate and helps them caramelize.
Q: Can I prepare this ahead of time?
A: Yes. Slice the vegetables and prepare the seasoning several hours ahead. Store refrigerated, then toss and roast just before serving.
Q: Can I use grape tomatoes instead of cherry tomatoes?
A: Yes. Either variety works well.
Q: Can I add onions?
A: Absolutely. Thinly sliced red, yellow, or sweet onion makes a delicious addition.
Q: What Parmesan works best?
A: Freshly grated Parmesan melts and browns better than many pre-shredded varieties.
Q: Can I make this dairy-free?
A: Yes. Replace Parmesan with a dairy-free Parmesan-style cheese or nutritional yeast.
Q: Is this recipe low-carb?
A: Yes. Zucchini, yellow squash, and tomatoes can fit well into a low-carb meal. The exact carbohydrate amount will depend on your serving size.
Q: Can I make it extra crispy?
A: Yes. Roast until golden, then broil for 1–2 minutes at the end. Watch closely because Parmesan can brown quickly.
Q: How should I store leftovers?
A: Refrigerate in an airtight container for up to 3–4 days. Reheat in the oven or air fryer for the best texture.
Q: Can I freeze the leftovers?
A: Freezing isn’t ideal because zucchini and squash can become soft and watery after thawing. For the best texture, enjoy them fresh or refrigerated.
