Ensaladilla Rusa: Why Every Spanish Bar Serves a Russian Salad and No One Finds It Strange

Walk into almost any bar in Spain, order a caña, and look at the tapas on offer. Somewhere on that list, as reliably as olives and tortilla, will be ensaladilla rusa. Russian salad. A creamy mound of potato, tuna, and peas that Spaniards eat by the ton, in a country not otherwise famous for its warmth toward Russia, and nobody blinks at the name.

It is one of the small, lovely absurdities of Spanish food culture. A dish named after a country on the other side of Europe has become one of the most Spanish things you can eat, a fixture of every tapas bar, supermarket deli counter, and family table. The story of how a Moscow restaurant’s luxury salad turned into Spain’s most casual bar snack is genuinely worth telling, and it makes the dish taste even better once you know it.

A Salad Born in a Moscow Restaurant

The original was not Spanish, not casual, and not cheap. It was created in the 1860s by a Belgian-born chef named Lucien Olivier, who ran an exclusive restaurant called the Hermitage in Moscow, catering to the Russian aristocracy. His salad was the height of luxury.

The first version bore almost no resemblance to the potato salad we know now. It was built on extravagant ingredients: grouse and other game birds, veal tongue, crayfish tails, caviar, all bound together with a rich, secret mayonnaise-style dressing that Olivier guarded jealously. He never wrote the recipe down, and it is said he took the exact formula to his grave.

The secrecy became part of the legend. Rival cooks spent years trying to reverse-engineer Olivier’s dressing, producing imitations that spread the salad’s fame even as the true recipe stayed locked away. By the time anyone might have prised it loose, the dish had already escaped into the wider world, evolving with every kitchen that adopted it. What survived was the idea, a composed salad of fine ingredients cloaked in a creamy dressing, which quickly became famous across Russia as Salat Olivier.

That is the dish’s true origin, and it explains the name that has confused visitors to Spain for generations. It really did come from Russia, invented in Moscow for wealthy diners, and its Russian identity was never in doubt at the start. Everything that happened afterward was a long, strange process of the salad shedding its finery and travelling far from home.

How It Lost Its Luxury and Kept Its Name

The grand version could not survive the twentieth century. After the Russian Revolution, the aristocracy that had eaten caviar-laden salads was gone, and the dish adapted to harder times. The game birds and crayfish gave way to what ordinary people could actually get: boiled potatoes, carrots, peas, and eggs, still bound in mayonnaise.

This humbler version is the one that spread, and spread astonishingly widely. It travelled across Europe and beyond, picking up local names and tweaks everywhere it landed. In much of the world it is simply Russian salad, in Italy insalata russa, in Portugal salada russa, and across Latin America ensalada rusa, often a fixture of Christmas tables. The same basic idea, boiled vegetables in a creamy dressing, put down roots on several continents.

What is striking is how completely the dish democratised while keeping its aristocratic-era name. The caviar vanished, the price collapsed, and the salad became food for everyone, yet it stayed tied by name to the Russian restaurant where a Belgian chef first assembled it for the rich. That gap between the humble reality and the exotic label is a big part of the dish’s charm wherever it is eaten, and nowhere more than in Spain.

It is a rare dish that carries its whole history in its name while tasting of none of it. Nobody eating a scoop of potato and tuna in a Madrid bar is thinking of Tsarist Moscow, and yet the thread runs unbroken from the one to the other.

How It Became Spanish

Exactly how the salad reached Spain is a little hazy, which is fitting for a dish with such a well-travelled past. There are a few competing accounts, and the truth is probably a blend of them.

One version has the recipe arriving through cookbooks: a French culinary text circulating in Spain in the mid-nineteenth century is sometimes credited with introducing the ensaladilla rusa name. Another popular theory ties it to the twentieth century and the Spanish Civil War, suggesting the dish was reinforced by exiles who had spent time in the Soviet Union and returned with a taste for it. However it arrived, it found perfect soil. Its creaminess, its make-ahead convenience, and its knack for stretching cheap ingredients suited Spanish tapas culture exactly.

The most telling twist came during the Civil War itself, when the word Russian became politically awkward. For a time the salad was pointedly renamed ensaladilla nacional, national salad, scrubbing the inconvenient foreign association. The renaming did not stick, and Russian salad it remains, but the episode captures how thoroughly Spain had adopted the dish. You only bother to rename something you already consider your own.

That sense of ownership is complete today. Ask a Spaniard where ensaladilla rusa comes from and many will answer, without irony, that it is simply Spanish, the Russian in its name reduced to a quaint footnote nobody thinks about while eating it.

What Goes In a Spanish One

Today the Spanish ensaladilla rusa has settled into a recognisable form, even if every bar and every abuela swears by their own version. At its base are boiled potatoes and carrots, diced small, with peas for colour and sweetness, all folded generously into mayonnaise.

The ingredient that makes it distinctly Spanish is tuna, usually good canned bonito del norte, which adds savour and substance and turns a side salad into something you can make a light meal of. Hard-boiled egg is common, both mixed in and used to garnish. Strips of roasted red pepper, often the sweet piquillo, add colour and a note of smoke, and green olives are a frequent finishing touch. In the south, especially around Seville and Cádiz, you will find versions crowned with boiled shrimp, which pushes it toward something almost celebratory.

The single biggest quality lever is the mayonnaise. Because the dish is essentially vegetables bound in mayo, that dressing is not a background element but the main event, and a homemade mayonnaise, or a good aioli, transforms the whole thing. A grandmother’s classic trick is to stir in a little of the oil from the tinned bonito, which threads the tuna flavour all the way through. Served cold, scooped up with crunchy breadsticks called picos and washed down with a cold beer or a vermouth, it is one of the great simple pleasures of a Spanish summer. It is cheap to make, it keeps for days, and it pleases nearly everyone at the table, which is really all a great tapa is ever asked to do.

A Dish Spaniards Argue About

For something so simple, ensaladilla rusa provokes strong opinions, and any Spaniard will happily tell you which bars make a good one and which commit crimes against it. It is a genuine love-it-or-hate-it dish, and the dividing line is almost always quality.

A great ensaladilla is fresh, generous with tuna, bound in real mayonnaise, and served properly cold. A bad one, the kind that gives the dish its detractors, is a gluey, over-mayonnaised scoop from a plastic tub that has sat too long, tasting mostly of refrigerator. The gap between the two is enormous, which is why Spaniards treat a bar’s ensaladilla as a kind of test: get this humble thing right and you probably know what you are doing with everything else.

The mayonnaise is where the arguments get heated. Purists insist on homemade, made properly with good olive oil, and look down on jarred versions. Others happily use a quality shop-bought mayo and spend their energy on the rest. There are regional loyalties too, over whether to include egg, how much tuna, whether shrimp belongs, and whether an olive on top is classic or fussy. None of it is settled, and none of it ever will be, which is exactly how Spaniards like their food debates.

Making It at Home

Ensaladilla rusa is forgiving and almost impossible to get wrong, which is part of why it is everywhere. The only real discipline is in the details: dice everything to a similar small size so each forkful is balanced, and do not overcook the potatoes, or the salad turns to paste.

It is also, crucially, a make-ahead dish, arguably better after a few hours in the fridge, which is what made it such a natural fit for tapas bars in the first place. Boil your vegetables, let everything cool completely before mixing so the mayonnaise does not slacken, fold it together, and chill. Then garnish it as plainly or as proudly as you like, from a simple scatter of olives to the full old-fashioned display of piped mayonnaise, grated egg yolk, pepper strips, and shrimp. Either way, you will have made a dish that has crossed a continent and two centuries to end up, improbably and deliciously, as the most Spanish salad there is.

Ensaladilla Rusa (Spanish Russian Salad)

Spain’s beloved tapas-bar potato salad: potatoes, carrots, and peas folded with tuna, egg, and plenty of mayonnaise, served cold with breadsticks. Better made a few hours ahead.

Serves: 6 as a tapa · Prep: 25 minutes, plus chilling · Cook: 25 minutes

Ingredients

• 500 g (1 lb) waxy potatoes, whole and unpeeled
• 2 medium carrots, whole and unpeeled
• 150 g (1 cup) peas, fresh or frozen
• 2 x 80 g tins good tuna or bonito in olive oil, drained (oil reserved)
• 3 large eggs, hard-boiled
• 200 g (¾ cup plus 2 tbsp) mayonnaise, ideally homemade
• 2 roasted red peppers or piquillo peppers, cut into strips
• Handful of green olives, pitted
• Salt, to taste
• Picos or breadsticks, to serve

Method

1. Put the whole potatoes and carrots in salted water, bring to the boil, and simmer until just tender, about 20 to 25 minutes. Cook the peas separately for a few minutes, then drain. Cool everything completely.
2. Peel the potatoes and carrots and dice them small, into even 1 cm pieces. Chop two of the hard-boiled eggs.
3. In a large bowl, combine the potatoes, carrots, peas, flaked tuna, and chopped egg.
4. Fold in the mayonnaise gently until everything is coated. For deeper flavour, stir in a teaspoon of the reserved tuna oil. Season with salt to taste.
5. Spread into a serving dish and smooth the top. Garnish with strips of roasted pepper, the remaining egg (sliced or with the yolk grated over), and the olives.
6. Chill for at least an hour before serving. Serve cold, with picos or breadsticks for scooping.

Notes

• Homemade mayonnaise makes a real difference here, since the dish is mostly vegetables and mayo. A good aioli works beautifully too.
• Southern Spanish versions add cooked, peeled shrimp, either mixed through or arranged on top.
• Boil the potatoes whole and in their skins so they do not absorb water and go mushy.
• Keeps, covered, in the fridge for up to 3 days, and the flavour improves overnight.
