Crocchè (also spelled 'crocché' or 'panzarotti') are the ubiquitous potato croquettes of Neapolitan street food—golden, crispy cylinders of mashed potato enriched with egg, Parmigiano, parsley, and sometimes a molten core of provola or mozzarella, fried to shattering perfection and sold from every pizzeria fritta and friggitoria in the city. The name derives from the French 'croquette,' another gift from the Bourbon court's French chefs, but the Neapolitan version has evolved into something distinctly its own—larger, more generously seasoned, and less refined than its French ancestor. The potatoes are boiled, riced while hot, and combined with egg yolks (never whites, which make them too firm), grated Parmigiano or pecorino, finely chopped flat-leaf parsley, salt, pepper, and sometimes a hint of nutmeg. The mixture is cooled until firm enough to shape into elongated cylinders roughly the size of a large thumb. Each crocchè is rolled in flour, dipped in beaten egg, and coated in fine breadcrumbs before frying in abundant hot oil (170-175°C) until deep golden. The exterior should be audibly crispy—a proper crocchè crackles when you bite through the crust—while the interior remains creamy, smooth, and potato-rich. The cheese-filled variant (crocchè ripieni) hides a cube of fior di latte or provola in the centre that melts into a stretchy, molten surprise. Crocchè are sold alongside pizza fritta, arancini, and other fried street foods at the friggitorie that line the streets of Spaccanapoli and Forcella, typically eaten standing, wrapped in paper, as a mid-morning merenda or a late-night snack. They represent the democratic genius of Neapolitan cooking: a few cheap ingredients, transformed by the alchemy of hot oil, into something irresistible.
Rice potatoes while hot for smooth texture. Use egg yolks, not whole eggs. Season with Parmigiano and parsley. Shape into cylinders. Triple coat: flour, egg, breadcrumbs. Fry at 170-175°C until deep golden.
Chill the shaped crocchè for 30 minutes before coating—they hold their shape better during frying. A tiny pinch of nutmeg in the potato mixture adds invisible depth. For the cheese-filled version, freeze the provola cubes first so they melt slowly during frying. Double-breadcrumbing (dip in egg and crumbs twice) creates an extra-crispy shell.
Using whole eggs (too dense). Under-frying (not crispy enough). Shaping when mixture is too warm (fall apart in oil). Oil temperature too low (greasy). Making them too large (raw centre). Not draining properly.
