ABOUT THIS RECIPEFrom Aubergine Classic to Courgette Bake
Parmigiana is often made with aubergine, tomato sauce and cheese; there are several regional versions and ways of preparing it. This version uses courgette, so it isn’t a classic melanzane alla parmigiana. Courgettes are most widely available in the warmer months, but you can also make this bake out of season with firm ones. Choose courgettes that feel heavy and have smooth skin; very large ones can contain a lot of seeds and moisture.
The most important step comes before the baking dish: fry the courgette slices in a hot pan. This evaporates some of their moisture and browns the cut sides. Arrange the slices in a single layer and cook them in batches if needed; an overcrowded pan cools down and makes the vegetables more likely to steam. Use a wide frying pan and add just a little oil at a time. The courgette doesn’t need to be completely cooked yet, as it will continue cooking between the sauce and cheese.
Simmer the tomato sauce briefly until it is no longer watery. A thick layer of sauce makes the dish soggy, while a thin layer adds plenty of flavour without overpowering the courgette. Mozzarella melts soft and stringy; drain fresh mozzarella well and pat it dry if needed. Grated Parmesan adds a saltier, more savoury note. If you don’t have Parmesan, use another hard cheese that grates well. For a slightly firmer result, replace some of the mozzarella with grated provolone.
The crumb topping is deliberately thin: breadcrumbs, olive oil and cheese brown on top, while the inside stays soft. Panko makes larger, airier crumbs; fine breadcrumbs form a more even layer. Use stale bread that you grind yourself if you prefer coarser, irregular pieces. Add the crumbs only over the top layer and don’t press them down, so they can toast instead of becoming soggy.
Serve the parmigiana after a short rest, with basil and, for example, a green salad with a fresh dressing. Toasted bread is also good for mopping up the tomato sauce. Store leftovers covered in the fridge and reheat within two days until piping hot throughout; the crumbs will be less crispy. If you have time, reheat them uncovered in the oven to dry out the topping a little.
