Spanish Potato Salad
This ensaladilla rusa recipe makes Spain's creamy potato salad — waxy potatoes, carrots, peas, tuna and egg bound in mayonnaise and crowned with white asparagus, piquillo peppers and olives. Unlike the German potato salad, which is dressed in vinegar and broth, or the American version, which has no fish, the Spanish one is defined by tuna and a cool, creamy dressing. One serving is about 360 g.
Ensaladilla rusa means 'little Russian salad', and it is Spain's version of the Olivier salad — the potato salad created by the French chef Lucien Olivier at the Hermitage restaurant in Moscow in the 1860s. While the Russian original uses chicken or ham and pickles, the Spanish version took tinned tuna, olives and peppers to suit Spanish tastes and what was available after the war, and it became a fixture of every tapas bar in the country. Most Spanish versions share the same base — potato, carrot, peas, egg and mayonnaise — with tuna as the defining addition.
Pairs well with: Crusty bread, pan con tomate and a cold beer

A true ensaladilla rusa uses waxy potatoes that hold their shape, tuna in olive oil, and a cool mayonnaise dressing — and it is always served cold.
Execution Methodology & Culinary Technique
Prep Stage: Start the Vegetables Boiling
20 Mins • Knife Work
Put the potatoes and carrots in a large pot, cover with cold salted water and bring to a boil. Boil the eggs in a separate small pot so their timing stays exact. While everything cooks, whisk the mayonnaise with the lemon juice and mustard for the dressing.
Maestro Tip: Start the vegetables in cold water — they cook evenly from the outside in, instead of going mushy outside and raw inside.
25 Mins Boiling water, 100°C (212°F)
Put the potatoes and carrots in a large pot, cover with cold salted water and bring to a boil. Simmer for 20–25 minutes until the potatoes are just tender when pierced with a knife — firm, not floury. Add the frozen peas for the last 3 minutes. Drain and leave to cool completely.
Cool the vegetables completely before mixing — warm potatoes drink up the mayonnaise and turn the salad greasy.
Done when: The potatoes are tender but still firm; a knife slides in with slight resistance.
10 Mins Boiling water, 100°C (212°F)
Put the eggs in a small pot, cover with cold water and bring to a boil. Boil for 10 minutes, then plunge into cold water. Peel 2 eggs and chop them; keep the third whole for garnish.
A grey ring around the yolk means overcooking — 10 minutes is enough for a large egg.
Done when: The yolks are fully set and pale yellow, with no grey ring.
10 Mins Room temperature
Peel the cooled potatoes and carrots and dice them into small, even cubes of about 1 cm. Put them in a large bowl with the peas and the 2 chopped eggs. Season lightly with the salt — remember the tuna and olives are salty already.
Dice small and even — big chunks fall apart when mixed and small ones turn to mash.
Done when: The dice are even and the vegetables are cool to the touch.
5 Mins Room temperature
Whisk the mayonnaise with the lemon juice and mustard. Add it to the bowl with the flaked tuna, then fold everything together gently with a large spoon until just coated. Do not stir hard or the potatoes will break.
Fold, do not stir — a few gentle turns from the bottom of the bowl are enough.
Done when: Every piece is coated in a thin, even layer of dressing and the potatoes are still in cubes.
60 Mins Chilled, at or below 4°C (39°F)
Cover and chill for at least 1 hour. To serve, spoon the salad into a shallow dish, smooth the top, and garnish with the sliced third egg, the white asparagus, piquillo strips and black olives. Serve cold, straight from the fridge.
Chilling is not optional — the flavours need the hour to marry, and the salad is meant to be eaten cold.
Done when: The salad is cold all the way through and holds its shape on a fork.
Finishing Touches & Plating
Chill for at least 1 hour, then garnish and serve cold with crusty bread — the salad should be cool, creamy and just firm enough to hold its shape on a fork.

Vitamins & minerals: Vitamin C and vitamin A (carrots, peas, peppers), vitamin B12 and vitamin D (tuna, egg), potassium (potatoes) and iron (egg, tuna).
Vegetables and Fish Together
Potatoes, carrots and peas bring fibre, potassium and vitamin C, while the tuna adds protein and omega-3 fats.
Protein from Tuna and Egg
About 20 g of protein per serving from tuna and egg — the salad eats like a proper lunch, not a side dish.
Cool and Make-Ahead
Served cold and made ahead, it is a calm, no-cook lunch for hot days — the fridge does the work.
Food Pairings
To optimize nutrient absorption and elevate the sensory depth, pair with these authentic accompaniments:
Sides
Crusty Bread
Crusty bread is made for scooping — the salad is halfway between a salad and a spread, and bread is the best way to eat it.
Vegetables
A Green Salad with Sherry Vinegar
A bitter green salad with sherry vinegar cuts through the rich mayonnaise and refreshes the palate between bites.
Drinks
A Cold Beer
An ice-cold beer is the classic tapas-bar partner — its bitterness and fizz balance the creamy, salty salad.
Full Menus
As Part of a Tapas Spread
Serve it as one of several small plates with pan con tomate, olives and jamón — the ensaladilla is the creamy anchor of the spread.
Complete menu
Serve the ensaladilla as part of a tapas spread with pan con tomate, olives and a cold beer, or as a light lunch with crusty bread and a green salad.
Digestive Guardrails
To prevent digestive distress, sluggishness, or palate clash, avoid pairing the dish with these elements:
Leaving the Salad Warm
Mayonnaise is an emulsion that splits when it warms, and a mayonnaise salad left in the sun becomes a food-safety risk as well as a greasy one. Keep the salad chilled at or below 4°C (39°F) and never leave it out for more than 2 hours. This is general guidance, not medical advice.
Using Floury Potatoes
Floury potatoes break apart when mixed and turn the salad into mash. Use waxy potatoes and mix gently, folding rather than stirring hard.
