Frittata con le Cipolle alla Genovese

Genoa, Liguria

Overview

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).

Flavour Context

Sweet caramelised onion depth; egg richness; Parmigiano savouriness; marjoram floral note; room temperature elegance

Key Principles

{"Onions (white or golden): slice thinly and cook in olive oil over medium-low heat for 30 min until golden-translucent and sweet — no caramel colour, just golden","6 eggs beaten with Parmigiano and a pinch of marjoram (the Ligurian herb signature) — season lightly, the cheese provides salt","Pour eggs over the cooled onions in the pan; cook on lowest heat, covered, 8–10 min until the top is just barely set","Flip using a plate: slide the frittata onto a plate, invert the pan over it, flip — the second side cooks 3–4 min on the residual heat of the pan","Cool to room temperature before service — hot frittata is too tender to slice cleanly; room temperature is the intended eating temperature"}

Pro Tips

{"Marjoram is the defining Ligurian herb — use fresh; dried marjoram lacks the floral quality needed","Adding a tablespoon of Parmigiano over the onions before the eggs adds a layer of cheese that doesn't disappear into the egg","The frittata keeps for 24 hours at room temperature — it is ideal for picnics and packed lunches","Cutting into wedges and serving with local olives and focaccia is the canonical Genovese antipasto board"}

Common Mistakes

{"Under-cooking the onions — the sweetness of completely caramelised onions is essential; raw or half-cooked onion remains sharp and overpowers the egg","High heat — the egg bottom burns before the top sets; minimum heat is the only approach for a creamy interior","Serving hot — the frittata is designed to be eaten at room temperature; hot is an incidental result of just-cooked","Using butter instead of olive oil — the Ligurian frittata is olive oil; butter gives a French omelette flavour"}
