Frittata con le Cipolle alla Genovese
Genoa's onion frittata — the defining Ligurian version of the Italian omelette: a thick, set, room-temperature egg cake with slowly caramelised onions as the sole filling. The Genovese frittata is cooked entirely on the stovetop (never finished in the oven), flipped using a plate to cook the second side, and rested before serving at room temperature. The onions must be cooked to a complete golden-jammy state — 30 minutes minimum — before the eggs are added. Served as antipasto or as a light main with salad. The Ligurian egg is richer-yolked than northern Italian varieties, often from 'uova dell'aia' (farmyard eggs).

The Method
1
Warm the olive oil in a 24–26 cm heavy-based frying pan over medium-low heat. Add the thinly sliced onions and a pinch of salt. Cook, stirring occasionally, for a full 30 minutes until the onions are golden, translucent, and completely sweet — no raw or sharp character should remain, though they must not darken to a deep caramel. Remove from the heat and allow the onions to cool in the pan for several minutes.
2
Beat the eggs with the grated Parmigiano and the fresh marjoram leaves. Season lightly with salt, bearing in mind that the cheese is already saline. Scatter an additional tablespoon of Parmigiano directly over the cooled onions in the pan, then pour the egg mixture evenly over them.
3
Return the pan to the lowest possible heat and cover with a lid. Cook for 8–10 minutes until the edges are fully set and only the very centre of the surface retains the faintest tremble when the pan is gently shaken.
4
Slide the frittata onto a large flat plate. Invert the pan over the plate and, holding both firmly, flip so the frittata returns to the pan with its uncooked side down. Cook uncovered for a further 3–4 minutes over residual low heat until the underside is lightly set and dry to the touch.
5
Slide the frittata onto a board or serving plate and allow it to rest, uncovered, until it reaches room temperature — at minimum 15 minutes. It will firm sufficiently to slice into clean wedges only once fully cooled; a hot frittata is too tender to hold its shape under the knife.

Quality Hierarchy
01
Reserve — Uova dell'aia — true Ligurian farmyard eggs with deep, rich yolks; aged Parmigiano Reggiano (24 months minimum); freshly picked marjoram from a Ligurian hillside; a single-estate Ligurian DOP olive oil.
02
Estate — Free-range eggs with visibly orange yolks; 18-month Parmigiano Reggiano; fresh marjoram from a kitchen garden; a quality Ligurian or Tuscan extra-virgin olive oil.
03
Market — Good free-range supermarket eggs; standard Parmigiano Reggiano; fresh marjoram from a produce counter; a reliable extra-virgin olive oil with low acidity.
04
House — Any free-range egg; Grana Padano in place of Parmigiano; fresh marjoram is still required — dried is not acceptable in this preparation; a neutral extra-virgin olive oil.

Sensory Tests
◇Smell. After 30 minutes over medium-low heat, the onions release a fully sweet, mellow aroma with no trace of pungency — the raw volatile compounds have cooked away entirely.
◇Sight. The onions are uniformly golden and translucent, collapsed to a soft mass, with no white or pale segments remaining.
◇Touch. The frittata is done on its first side when the edges pull cleanly from the pan and only the very centre yields slightly under a fingertip pressed through the lid's condensation.
◇Sight. At room temperature, the frittata holds a clean vertical edge when sliced into a wedge — the interior is set but moist, not rubbery.
◇Where it lives or dies. The onions must cook for a full 30 minutes to a golden, jammy sweetness before the eggs are added — under-cooked onions remain sharp and overpower the egg, and the dish cannot recover from that point.
