How To Make It
Cut the ends off each zucchini.
Cut the zucchini into 1/2 thick slices.
Place zucchini slices in a large bowl.
Add garlic.
Sprinkle in pepper.
Sprinkle in salt.
Drizzle on olive oil.
Sprinkle in parsley.
Mix well to coat the zucchini slices evenly.
Arrange the zucchini slices on a baking sheet.
Sprinkle the Parmesan cheese on top of each zucchini slice. Bake for 20 to 25 minutes, until the zucchinis are golden and the cheese has turned golden. Keep an eye on them to keep them from burning. Remove from the oven and serve warm.
Note
Ensure the zucchini slices are uniform in thickness. This will help them roast evenly, preventing some pieces from becoming too soft while others remain undercooked.
Storage
To store Parmesan roasted zucchini, let it cool completely, then transfer it to an airtight container and refrigerate for up to 3 days. To reheat, spread the zucchini on a baking sheet and warm in the oven at 350°F for about 5-8 minutes, or until heated through. This method helps the zucchini stay crisp rather than becoming too soft, though you can also reheat it in an air fryer at 350°F for a few minutes to bring back extra crispiness.
Helpful Hints
Pro tip: Arrange properly!
Arranging the zucchini in a single layer on the baking sheet will allow each slice to roast properly and develop that desired golden, slightly crispy texture.
Here are some helpful hints for making a Parmesan roasted zucchini in the oven recipe:
- Prep the Zucchini for Even Roasting: Cut the zucchini into even slices or sticks for uniform cooking. This helps prevent some pieces from getting mushy while others remain undercooked. Aim for ¼ to ½-inch thickness, so they roast properly without turning too soft.
- Use a High-Quality Parmesan: Freshly grated Parmesan will give the best flavor and a deliciously crisp coating. Pre-grated Parmesan can work in a pinch but doesn’t have quite the same texture and can be saltier, so consider adjusting the salt accordingly.
- Don’t Skimp on the Olive Oil: A light coating of olive oil is essential to help the zucchini roast instead of steam. The oil also helps the Parmesan adhere to the zucchini, creating that flavorful golden-brown crust. Just be careful not to overdo it, as too much oil can make the zucchini soggy.
- Add Herbs for Extra Flavor: Fresh herbs like parsley, basil, or rosemary add an aromatic layer to the dish and complement the Parmesan. You can sprinkle herbs on just before serving for a burst of freshness or roast them with the zucchini for a subtler flavor.
- Roast at a High Temperature: Roasting at 400°F (200°C) encourages browning and keeps the zucchini slightly crisp on the outside while tender inside. Be sure to keep an eye on them, as overcooking can lead to a mushy texture.
Serving Suggestions
Zucchini roasted in the oven makes complements grilled meats like chicken, steak, or fish exceptionally well, adding a burst of flavor and vibrant color to the plate. For a complete meal, consider serving it alongside a simple pasta dish tossed with olive oil, garlic, and herbs, allowing the roasted zucchini to shine through as a fresh and flavorful addition.
Another delicious way to enjoy roasted zucchini is by incorporating it into salads. After roasting, let the zucchini cool slightly before adding it to a mixed greens salad with cherry tomatoes, avocado, and a light vinaigrette. The warmth of the zucchini enhances the salad, making it more satisfying while adding a unique texture that contrasts with the crisp greens. This combination not only tastes great but also boosts the nutritional value of your meal.
For a fun and casual twist, try serving the Parmesan roasted zucchini as a topping for flatbreads or pizzas. Spread some marinara or pesto on a prepared crust, then add the roasted zucchini along with your choice of cheese and additional toppings. Bake until bubbly and golden for a delightful dish that’s perfect for a family dinner or entertaining guests. This approach takes the simple roasted vegetable and transforms it into a delicious and visually appealing main course.
