Steps to prepare oven-baked zucchini gratin
To start your easy recipe, wash the zucchinis and trim the ends. At this point slice them lengthwise. It’s not necessary to use a mandoline because, being gratinated with a fairly flavorful coating, it is better for them to have some thickness to provide softness and sweetness to your dish. A very sharp knife, used carefully, is sufficient to obtain regular slices. Arrange the slices on a baking tray lined with parchment paper, spacing them slightly apart.
While the oven heats, focus on the gratin mixture. In a food processor or on a cutting board, finely chop the parsley, basil, garlic clove and chili pepper. In a bowl, mix this chop with the breadcrumbs, Parmigiano Reggiano and the grated lemon zest. Add a drizzle of extra virgin olive oil to moisten the mixture: this technical step allows you to obtain a coating that adheres perfectly to the zucchini and browns without burning.
Take the zucchinis you arranged on the tray and evenly sprinkle them with the aromatic breadcrumb mixture you just made. Press gently with your fingers so the fragrant mix stays well attached to the surface. Add a pinch of salt and a final drizzle of extra virgin olive oil over each slice. Bake at 392°F (200°C) for about 15-20 minutes, using the fan setting if you want a more pronounced crust. Your easy recipe is ready when the surface looks amber and inviting.
Once cooking is complete, take your oven-baked zucchini gratin out of the oven and let them rest for a couple of minutes before serving. This short waiting time allows the zucchini fibers to stabilize, making the slice firmer and easier to lift without breaking the crust. You can enjoy them hot, straight from the oven, or at room temperature, when the scents of lemon and basil are even more persistent and harmonious.
Tips for a perfect result
Constant thickness: Try to cut the slices all the same thickness, about 1/5 inch (0.2 in), so the oven cooking will be even across the tray.
Organic lemon: Since you use grated zest, make sure the lemon is untreated to ensure a genuine and very fragrant easy recipe.
Do not overlap: For a perfect gratin, never overlap the zucchini slices; hot air must circulate freely around each piece.
Tasty variations
Nutty note: Add chopped pine nuts or flaked almonds to the breadcrumb mix to give extra crunch to your zucchinis.
Oregano aroma: If you prefer a more rustic aroma, replace the basil with dried oregano, which pairs very well with Parmigiano.
Mediterranean touch: Stir a teaspoon of rinsed, chopped capers into the breadcrumb mix for a salty Mediterranean boost.
Storage
In the refrigerator: You can store the zucchinis for 1-2 days in an airtight container.
How to reheat: To bring back the crunchy coating, avoid the microwave; pass them under the oven grill for a few minutes or use an air fryer.
FAQ (Questions and Answers)
Can I use pecorino instead of Parmigiano?
Certainly, pecorino will give a saltier and stronger note, perfect if you love bold flavors.
The zucchinis release water, what should I do?
If the zucchinis are very watery, you can salt them lightly 10 minutes before seasoning and blot them with kitchen paper.
Can I prepare them in advance?
Yes, you can bread them in advance and bake them only at the last moment to keep them crispy.
