Vitello Tonnato: Piedmont's Cold Veal With Tuna Sauce, Why Veal and Tuna Work Together, and the Emulsified Sauce That Shouldn't Work But Does

Vitello tonnato is a Piedmontese summer classic that reads, on paper, as a dish that should not exist: cold sliced veal covered in tuna sauce. In practice, it is one of the great Italian antipasti — mild, savory, slightly briny, refreshing in the heat, and deeply satisfying in a way that neither the veal nor the tuna provides alone.

The dish is primarily associated with Piedmont and dates to the early 19th century, when it appears in northern Italian cookbooks. The original versions used tuna preserved in oil and a mayonnaise-style emulsion as the sauce base — the same fundamental approach used today. It has spread across Italy as a summer staple but remains most identified with Turin and the Piedmontese table.

Why Veal and Tuna Work Together

Both veal and canned tuna are:

• Mild — neither has aggressive, competing flavors
• Lean — the fat in the sauce is provided by the mayonnaise and olive oil, not by either protein
• Protein-forward — both have a clean, savory quality that takes on the flavor of what surrounds them

The tuna sauce does not taste of fish in an aggressive way — the anchovy provides most of the savory depth, the capers provide acidity and brine, the lemon provides brightness, and the tuna provides body and a subtle, savory richness. The result is a sauce that is identifiably tuna-based but functions primarily as a savory, creamy emulsion rather than a seafood condiment.

The Sauce

There are two versions:

1. Classic (older): tuna, hard-boiled egg yolks, capers, anchovy, oil, lemon — fully emulsified without commercial mayonnaise
2. Modern (most common now): tuna blended with commercial mayonnaise, capers, anchovy, and lemon — faster, more consistent

Both produce the same essential sauce. The classic version has slightly more texture and a rounder flavor from the hard-boiled yolks; the modern version is silkier.

The sauce should be smooth and cream-like — not chunky. Use a food processor or immersion blender. If too thick, thin with a small amount of the veal cooking liquid or water.

The Veal

Correct cuts: Eye of round, rump, or topside — lean cuts with a uniform shape that poach or roast cleanly and slice thin without falling apart.

Poached method (most common): Simmer the veal in a court-bouillon (water, white wine, onion, celery, carrot, bay leaf, peppercorns) for 45–60 minutes until just cooked through and still slightly pink (62–65°C internal). Allow to cool completely in the cooking liquid — this keeps it moist. Chill overnight before slicing.

Roasted method: Sear; roast at 180°C to 62°C internal; rest; chill overnight. Produces a more concentrated flavor.

The Complete Recipe

Serves: 6 as antipasto | Time: 1.5 hours active + overnight chilling

For the Veal

• 800g veal eye of round or rump, tied into a cylinder
• 1 liter white wine
• 1 liter water
• 1 onion, halved
• 2 stalks celery
• 1 carrot
• 2 bay leaves, 10 peppercorns, 1 teaspoon salt

For the Tuna Sauce

• 200g canned tuna in oil, drained
• 150g good-quality mayonnaise
• 30g capers in brine, drained (plus more for garnish)
• 4 anchovy fillets in oil
• 2 tablespoons lemon juice
• 2–4 tablespoons reserved veal cooking liquid (to adjust consistency)
• Salt, white pepper to taste

Method

1. Poach the veal: Place veal in a pot with all court-bouillon ingredients; bring to a simmer; cook 45–60 minutes until just cooked through (62–65°C). Cool completely in the liquid; refrigerate overnight.

2. Make the sauce: Blend tuna, mayonnaise, capers, anchovy, and lemon juice until completely smooth. Adjust consistency with a little cooking liquid — it should coat a spoon but still flow. Season.

3. Slice the veal: Remove from cooking liquid; pat dry; slice as thin as possible (2–3mm) with a sharp knife or meat slicer.

4. Assemble: Fan the veal slices across a large serving platter; pour the tuna sauce over the top to cover completely; scatter with additional capers.

5. Rest: Allow to sit at room temperature 30 minutes before serving — the sauce should not be fridge-cold when eaten.

Serve: As a starter, accompanied by crusty bread or grissini.
