Fegato alla Veneziana

Fegato alla Veneziana — paper-thin slices of calf's liver flash-fried with sweet, long-caramelised onions — is the defining offal dish of Venice, eaten in bacari alongside a glass of prosecco or ombra (house wine). Unlike the assertive liver dishes of other traditions, the Venetian method uses sweet white onions cooked very gently for 30 minutes, their sweetness counterbalancing the liver's iron richness.

Serves: 4

Ingredients

• 600g (1¼ lb) calf's liver, sliced paper-thin (3–4mm), membranes removed
• 4 large white onions (about 800g / 1¾ lb), halved and sliced into thin half-rings
• 4 tbsp (60ml) extra-virgin olive oil
• 30g (2 tbsp) unsalted butter
• Fine sea salt and black pepper
• 3 tbsp (45ml) dry white wine
• Small handful flat-leaf parsley, chopped
• Lemon wedges, to serve
• Soft polenta or grilled white bread, to serve

Instructions

1. Heat 2 tbsp olive oil with the butter in a wide pan over the lowest possible heat. Add the sliced onions with a pinch of salt. Cook, stirring occasionally, for 30–35 minutes until completely soft, golden, and sweet — they should almost melt. Do not rush this step. Set onions aside.
2. Pat liver slices completely dry. Season generously with salt and pepper on both sides.
3. Heat remaining 2 tbsp olive oil in the same pan over the highest heat until almost smoking.
4. Working in batches, sear the liver slices for 30–45 seconds per side — no more. They should be golden on the outside but still slightly pink within. Overcooking makes liver dry and bitter.
5. Return all liver to the pan. Add white wine and toss for 20 seconds to deglaze. Return onions to the pan and toss together gently.
6. Scatter with parsley and serve immediately with soft polenta or grilled bread, and lemon wedges.

Cook's Notes: Calf's liver is far milder than beef or pork liver. Ask your butcher to slice it thin — this is the key to the Venetian version's tenderness. If you can only find beef liver, soak it in milk for 1 hour before cooking to mellow the flavour.
