Traditional Spanish Salad: Ensalada Campera

Ensalada campera is a traditional Spanish country-style potato salad, usually served cool or at room temperature. Tender potatoes, ripe tomatoes, peppers, tuna, hard-boiled eggs and olives are tossed with olive oil and vinegar for a hearty salad that needs no mayonnaise and suits a relaxed lunch or shared table.

Ingredients

2 lb (900 g) waxy or all-purpose potatoes, similar in size
3 large eggs (about 5 oz / 150 g without shells)
2 medium ripe tomatoes, about 2 cups (300 g) chopped
1 medium green bell pepper, about 1 cup (150 g) chopped
½ small red or yellow onion, about ½ cup (75 g) finely chopped
2 cans tuna in olive oil or water, 5 oz (142 g) each, drained weight about 8 oz (226 g) total
½ cup (75 g) pitted green olives, whole or halved
⅓ cup (80 ml) extra-virgin olive oil
2 tbsp (30 ml) sherry vinegar
¾ tsp (4 g) fine salt, plus 2 tsp (10 g) for the potato water
¼ tsp (about ½ g) freshly ground black pepper
2 tbsp (8 g) chopped flat-leaf parsley, optional

Instructions

Cook the potatoes. Scrub the potatoes, leave them whole and unpeeled, and put them in a large pot. Cover with cold water by about 1 in (2.5 cm), add the 2 tsp (10 g) salt, and bring to a boil. Lower the heat to a steady simmer. Cook for 20–25 minutes, depending on size, until a thin knife slides into the center without much resistance. Avoid cutting them before boiling; whole potatoes are less likely to become waterlogged.
Boil the eggs. While the potatoes cook, put the eggs in a small saucepan and cover with cold water. Bring to a boil, then lower the heat to a gentle simmer and cook for 10–11 minutes. Transfer them to cold water and leave until cool enough to handle. For whole boiled eggs, the yolk and white should be firm. Peel and set aside.
Cool and prepare the vegetables. Drain the potatoes as soon as they are tender. Leave them in the colander for 15 minutes, until they are cool enough to handle but still slightly warm. Meanwhile, chop the tomatoes and green pepper into bite-size pieces and finely chop the onion. If the onion tastes especially sharp, rinse it briefly under cold water and pat it dry; this softens its bite without changing the basic character of the salad.
Make the dressing. Whisk the olive oil, sherry vinegar, ¾ tsp (4 g) salt and black pepper in a small bowl. The dressing should taste lively and a little tart on its own; the potatoes will absorb some of that seasoning. Sherry vinegar is a familiar Spanish choice. If it is hard to find, use red wine vinegar for a slightly sharper, less rounded flavor.
Assemble the salad. Peel the potatoes if you prefer, then cut them into roughly ¾-in (2 cm) chunks. Put them in a large serving bowl and gently toss with about half the dressing while they are still just warm. Add the tomatoes, pepper, onion, drained tuna and olives. Break the tuna into generous flakes rather than mashing it, and fold everything together carefully so the potatoes hold their shape.
Finish and chill. Cut the peeled eggs into quarters or thick slices and arrange them over the salad, or fold them in gently. Pour over the remaining dressing and add parsley if using. Cover and refrigerate for 30 minutes so the flavors can mingle. Let the salad stand out of the refrigerator for 10–15 minutes before serving if you want the olive oil and tomato flavors to show more clearly. Keep it chilled again promptly after serving.

Tips

Choose potatoes that hold their shape. Waxy potatoes, such as red-skinned or small yellow potatoes, are especially reliable. All-purpose potatoes also work if you stop cooking as soon as a knife passes through easily. Floury baking potatoes can break down when tossed, so handle those gently and expect a softer, more rustic salad.
Dress the potatoes while they are warm. They take up seasoning more readily before they cool completely. Add the dressing in stages, though: tomatoes release juice as they sit, and you may not need every last drop. If the salad seems dry after chilling, drizzle in a little olive oil and vinegar rather than stirring hard.
Drain the tuna and olives well. Excess canning liquid can dilute the dressing and make the bottom of the bowl watery. Tuna packed in olive oil gives a richer result; tuna packed in water tastes lighter. Either is suitable, and the oil from the can can replace a spoonful of the recipe’s olive oil if it is fresh and pleasantly flavored.
Keep the pieces generous and the mixing gentle. This is a substantial, composed salad rather than a finely chopped salsa. Large potato chunks and visible flakes of tuna give each serving good texture. Add the eggs last or arrange them on top so they do not crumble through the bowl.

Serving Suggestions

Serve ensalada campera as a light main dish for lunch, especially on a warm day, or offer it as part of a larger meal. It is filling enough to stand on its own because it combines potatoes, tuna and eggs, but it also fits naturally beside grilled vegetables, roast chicken or simply cooked fish. For a Spanish-style spread, set it out with crusty bread, a bowl of olives and a few other small plates; the bread is useful for catching the seasoned oil and tomato juices.

For a neat presentation, spoon the salad onto a broad platter and arrange the egg wedges and olives where they remain visible. A little extra parsley is optional, not essential. Serve it cool rather than icy cold if possible: a short rest on the counter softens the chill and makes the olive oil less firm. If serving buffet-style, put out a modest amount at a time and replenish it from the refrigerator instead of leaving the whole bowl at room temperature for a long meal.

Variations

Ensalada campera has many household and regional versions, so the combination can be adjusted without treating one exact ingredient list as the only correct one. Some cooks use white onion instead of red or yellow, while others leave onion out. A small amount of finely sliced spring onion can be used in its place for a milder flavor. Red bell pepper adds sweetness and color; it can replace the green pepper, though the salad will taste less grassy and more mellow.

For a version without tuna, leave it out and add a few extra olives or another chopped hard-boiled egg. The result is less substantial but still works as a side salad. If you want a more pronounced seafood flavor, use tuna packed in olive oil and keep the flakes fairly large. Anchovies are a much saltier alternative, not a one-for-one substitute, so use only a few finely chopped fillets and reduce the added salt.

Sherry vinegar is worth seeking out if you enjoy Spanish cooking, but red wine vinegar is a practical stand-in. White wine vinegar also works, although its cleaner, sharper taste can make the dressing seem more acidic. Start with 1½ tbsp (22 ml), taste, and add the remaining vinegar only if needed. A pinch of sweet paprika can be added to the dressing for a gentle earthy note, but it is optional and changes the salad’s flavor rather than being required for the basic preparation.

Storage and Reheating

Because this salad contains cooked potatoes, tuna and eggs, refrigerate it within 2 hours of making or serving it; in a hot setting above 90°F (32°C), refrigerate it within 1 hour. Store leftovers in a covered container at 40°F (4°C) or colder. For best texture and flavor, eat them within 3 days. Food-safety guidance allows most cooked leftovers 3–4 days refrigerated, but the cut tomatoes and dressed potatoes can become watery, and the eggs and tuna are best enjoyed while fresh.

There is no need to reheat ensalada campera. It is intended to be served cool or at room temperature, and warming it can make the tomatoes soft and the dressing greasy. Take only the amount you plan to eat from the refrigerator, then return the rest promptly. If the salad has been left out longer than the safe time, discard it rather than relying on smell or appearance. Freezing is not recommended: potatoes tend to become grainy after thawing, and the fresh vegetables lose their texture.

Frequently Asked Questions

Can I make ensalada campera ahead?
Yes. You can cook the potatoes and eggs, cool them, and refrigerate them separately for up to a day before assembling. For the freshest texture, chop the tomatoes and combine the salad on the day you plan to serve it. If you make the complete salad ahead, keep it covered and chilled, and add a small splash of olive oil and vinegar only if it seems dry before serving.

Should I peel the potatoes?
Either choice is fine. Peeling after boiling gives a softer, more uniform salad, while leaving the skins on adds texture and saves a step, especially with thin-skinned potatoes. If you leave the skins on, scrub the potatoes well before cooking and remove any blemished areas. In either case, let them cool enough to handle before cutting.

Can I use fresh tuna instead of canned?
Yes, but it changes the preparation and the finished texture. Cook the tuna separately, then check the thickest part with a food thermometer; the USDA FSIS safe minimum internal temperature for fish is 145°F (63°C). Let it cool before flaking it into the salad. Canned tuna is the convenient, familiar option here and does not need extra cooking.

Why did my salad turn watery?
Very juicy tomatoes, wet olives or tuna that was not drained can add liquid to the bottom of the bowl. The potatoes may also have been overcooked and broken up during mixing. Drain the add-ins well, use potatoes that hold their shape, and fold rather than stir. If liquid gathers after chilling, spoon off a little before serving and refresh the seasoning with a small amount of oil and vinegar.

Can I make it without eggs or tuna?
Yes. Omit either ingredient, or both, to suit the meal. Without tuna and eggs, it becomes a lighter potato-and-vegetable salad; you can add extra olives or a handful of cooked white beans for more substance. If leaving out the salty tuna, taste the dressing before serving and adjust the salt gradually rather than adding the full amount automatically.

Is this salad served cold or warm?
It is usually served cool or at room temperature, not hot. Tossing the potatoes with some dressing while they are slightly warm helps them absorb flavor, but the finished salad benefits from a short chill. Letting it stand for 10–15 minutes before serving takes the refrigerator edge off without leaving it out for an extended period.
