This version of eggplant parmigiana is the most popular outside of Italy. Hailing from Campania, this variation on a dish is made with eggplants, olive oil, onions, basil, tomatoes, mozzarella or fior di latte cheese, and grated Parmigiano-Reggiano.
The eggplants are peeled, sliced, and shortly fried, then arranged in a baking dish over the tomato sauce along with the cheese, basil leaves, and grated Parmigiano-Reggiano. The layers are repeated, and the final one should end with tomato sauce and grated cheese.
