How to Make Tonnato, the Italian Tuna Sauce From โ€˜The Bearโ€™


A chilled Italian sauce thatโ€™s perfect for summer is having a moment, thanks to โ€œThe Bear.โ€

Though the crew has been consistently slinging marinara, it was another sauce that got a special shoutout this season, like Hamburger Helper did earlier on.

Episode 9 is titled โ€œTonnato,โ€ after the creamy tuna sauce โ€” a dish that carries emotional significance for both Carmy (Jeremy Allen White) and his estranged mother Donna (Jamie Lee Curtis).

In this episode, Carmy arrives at Donnaโ€™s doorstep to hand over old photographs she asked for. He tries to leave โ€” but she coaxes him inside and they hash things out over faded pictures.

In a quieter moment, Donna recalls a day alone in Italy after an argument with Carmyโ€™s father.

A lady at a cafe made the sobbing Berzatto โ€œred roasted peppers and a sauceโ€ that tasted like โ€œmayonnaise with fish.โ€ She says it โ€œlooked disgustingโ€ but was โ€œdelicious.โ€

โ€œTonnato,โ€ Carmy says.

He makes her chicken tonnato, a dish he used to regularly prepare at French Laundry, reviving his motherโ€™s memory of that meal in Italy.

Tonnato โ€” โ€œtunaโ€ in Italian โ€” comes from the Piedmont region in northwestern Italy and is typically made with tuna, anchovy, olive oil, lemon and mayonnaise, though some people add capers, dill, basil and more. The ingredients are then blended to form a smooth, creamy, beige sauce, which is commonly spooned over cold, sliced veal to make the dish called vitello tonnato.

These days, itโ€™s not unusual to see it drizzled atop sliced tomatoes, asparagus, green beans and other vegetables.

โ€œItโ€™s a delicacy,โ€ says Aimee France, a baker and food influencer who recently shared her off-the-cuff recipe online, โ€œIf youโ€™ve never had it, you gotta try and donโ€™t hate itโ€™s so good, itโ€™s like the dip of the summer.โ€

According to Italian food and wine magazine Gambero Rosso, the first published recipe for tonnato is in a 1862 book titled, โ€œThe kitchen of weak stomachs: that is, a few uncommon, simple, cheap and easy to digest dishes with some rules on good governance of the digestive tract,โ€ which has three different recipes for vitello tonnato. The original sauce had tuna, anchovy, veal stock, oil and lemon.

โ€œIf you like tuna in general, or just are a tuna salad lover, you will love tonnato,โ€ says France says, who likes to serve the sauce with crudites and potato chips, and even on tomato sandwiches.

Tonnato sauce is surprisingly simple to make, involving four steps and one appliance. Katherine Lewinโ€™s recipe swaps out the veal for tomatoes, making it perfect for summer.

To a blender or food processor, add lemon zest and juice, grated garlic, tuna, anchovies, mayonnaise, mustard, capers and black pepper.

While this blends, drizzle in some oil. And thatโ€™s really it. Once smooth, pour that over your tomatoes and imagine youโ€™re in northern Italy as you take a bite. Maybe throw on a silk scarf and sunglasses.
