Sarde in Saor is one of Venice's oldest and most beloved dishes, born centuries ago as a way to preserve fried fish on long sea voyages. The magic lies in the agrodolce — the sweet-sour balance of caramelised onions, plump raisins and toasted pine nuts bathed in white wine vinegar. Like all great Venetian food, patience is the secret ingredient: the flavours deepen dramatically after a full day in the fridge.

Sarde in Saor – Authentic Venetian Sweet & Sour Sardines

Ingredients

800 g fresh sardines, cleaned and butterflied
500 g white onions, thinly sliced
150 ml white wine vinegar
50 g raisins
40 g pine nuts
50 ml dry white wine
Flour, for dredging
Extra-virgin olive oil, for frying and sautéing
Salt and freshly ground black pepper
2 bay leaves

Method

Soak the raisins in warm water for 15 minutes, then drain and pat dry. Set aside.
Season the cleaned, butterflied sardines lightly with salt and dredge them in flour, shaking off any excess.
Pour enough olive oil into a wide frying pan to shallow-fry. Heat over medium-high until shimmering, then fry the sardines in batches for 2–3 minutes per side until golden and crisp. Transfer to a plate lined with kitchen paper and season lightly with salt.
Discard the frying oil and wipe the pan. Add 3–4 tablespoons of fresh olive oil and the sliced onions with a pinch of salt. Cook over low heat, stirring occasionally, for 20–25 minutes until the onions are very soft, sweet and just starting to turn golden — do not rush this step.
Add the bay leaves, white wine and white wine vinegar to the softened onions. Stir well and simmer for 5 minutes over medium heat to mellow the acidity slightly.
Stir in the drained raisins and pine nuts and cook for a further 2 minutes. Taste and adjust salt if needed. Remove from the heat.
In a deep dish or ceramic container, layer the sardines and the warm onion mixture alternately, starting and finishing with the onion layer. Ensure every sardine is well covered.
Allow to cool to room temperature, then cover and refrigerate for at least 12 hours — ideally 24–48 hours — before serving at room temperature.

Tips from the kitchen

💡 Ask your fishmonger to clean and butterfly the sardines for you to save time. Fresh, plump sardines make all the difference — avoid frozen if possible.

💡 Do not skip the resting time. Sarde in Saor is genuinely better on day two or three, as the sardines absorb the agrodolce marinade and the flavours fully harmonise.

💡 For a more traditional Venetian touch, add a small pinch of ground cinnamon or a few whole cloves to the onion mixture — a nod to the spice trade that once made Venice rich.

Frequently asked questions

How long do sarde in saor keep in the fridge?

Stored in a well-sealed container, sarde in saor keep beautifully in the fridge for up to 4–5 days. The flavour actually improves over the first two days, making it an ideal make-ahead dish.

Can I use a different type of fish?

Sardines are traditional and ideal, but the same saor marinade works well with small sole (sfogi), sprats or even fillets of mackerel. The fish should be small, oily and suitable for shallow-frying.

Should sarde in saor be served hot or cold?

Always at room temperature, never straight from the fridge. Remove the dish from the refrigerator about 30 minutes before serving. It is typically served as an antipasto, often on top of a slice of white polenta in Venice.
