💖 Why This Recipe Works
- Crispy on the outside, tender on the inside—thanks to the high-heat roast
- Uses simple ingredients for big flavor in under 25 minutes
- Pairs perfectly with everything from grilled chicken to pasta or steak
⭐ Star Ingredients
- Zucchini – Go for firm, medium zucchini—those big ones can be watery. Patting them dry before roasting helps them crisp instead of steam, which makes all the difference.
- Parmesan Cheese – Freshly grated is key! It melts into a golden crust and adds that perfect salty, nutty bite. I always use Parmigiano-Reggiano for the best flavor and texture.
- Garlic Powder – It gives deep, even flavor without burning like fresh garlic can at high heat. Just a light sprinkle brings that warm, savory vibe that makes this dish so moreish.

🔪 How To Make Parmesan Roasted Zucchini
- Step 1: Preheat your oven to 400°F and lightly grease a baking sheet with olive oil. Slice the zucchini into ½-inch thick rounds and pat dry with a paper towel.
- Step 2: Brush or spray with olive oil, then season with garlic powder, salt, pepper, and most of the Parmesan (reserve a little for later).
- Step 3: Place the baking sheet in the oven. Roast for 9–10 minutes, then switch to broil for 1–2 minutes until crispy and golden on top.
- Step 4: Top with reserved Parmesan and fresh parsley, then serve hot and crispy!
💡Hint: Don’t skip drying the zucchini slices—removing moisture helps them crisp instead of steam.
👩🍳 Expert Tips
Want that next-level crispy zucchini with loads of flavor? These quick tricks make a big difference:
- Preheat your baking sheet – Pop the pan in the oven while it heats. That sizzle when the zucchini hits the hot surface? Instant caramelization and extra crispiness.
- Salt before roasting – Lightly salt your zucchini slices and let them sit for 10–15 minutes, then pat them dry. This draws out excess moisture so they roast—not steam.
- Finish with lemon zest or herbs – A sprinkle of lemon zest or chopped parsley after roasting adds freshness, aroma, and that final pop that makes it feel gourmet.
💭 FAQs
Yes! Air fry at 375°F for 8–10 minutes. You’ll still get that golden, crispy finish with even less oil.
Yes, you can definitely use an oil spray instead of regular olive oil for roasting zucchini.
Oil spray can help evenly coat the zucchini slices with a lighter layer of oil, which is great if you’re looking to reduce the overall fat content of the dish. It also ensures a more uniform and mess-free application, helping the Parmesan and seasonings adhere well to the zucchini while promoting even crisping during roasting.
Just make sure to spray both the baking sheet and the zucchini slices thoroughly to prevent sticking and to achieve that delicious golden crust.
Not ideal—zucchini loses its texture after freezing. Best to enjoy fresh or repurpose leftovers into veggie pasta or omelets.
Store Parmesan Roasted Zucchini in an airtight container in the refrigerator for up to 3 days.
