In Ecuadorian households, this vibrant Ecuadorian Tuna Potato Salad (ensalada de papa y atún) represents the heart of everyday cooking—resourceful, nourishing, and bursting with fresh flavors.

What is Ecuadorian tuna potato salad?
Ecuadorian tuna potato salad is a popular traditional dish that combines tender potatoes, tuna and citrus-marinated tomatoes and onions. Unlike creamy American potato salads, this version has a bright, citrus-based dressing that lets the fresh vegetables shine! The combination of starchy potatoes, protein-rich tuna, and zesty lime juice creates a balanced meal enjoyed throughout the country as a lunch staple or side dish.

Ingredient For Ecuadorian Ensalada de Papa y Atún

- Potatoes: Use waxy potatoes like Russet potatoes or gold potatoes. Wash them well and leave them unpeeled for the best results.
- Red Onion: Adds a sharp flavor and crunchy texture. Make sure to soak them in cold water to remove the overpowering flavor!
- Tomatoes: Add juiciness, freshness, and a touch of natural sweetness.
- Cilantro: For a bright, herbal flavor. If you don’t like cilantro, feel free to replace it with parsley.
- Lime: Fresh lime juice adds the best flavor here! It adds a tangy flavor that will balance out the richness of the potatoes and tuna.
- Tuna Fish: Canned tuna packed in oil is preferred, but you can also opt for tuna packed in water.
- Olive Oil: If you are using tuna packed in oil, use the oil from the cans. Otherwise, add some extra virgin olive oil to the tuna salad.
- Salt: To taste!

Tips for Success
- Don’t peel the potatoes before boiling! Cooking potatoes in their skins helps preserve flavor and prevents them from becoming too watery.
- Soak those onions! This step is crucial—properly soaked and rinsed onions add flavor without overwhelming the dish with sharpness.
- Marinate the vegetables. Allowing the onion-tomato mixture to sit with lime juice for 30 minutes creates a quick “curtido” that infuses the entire salad with flavor.
- While you can serve immediately, the flavors develop beautifully when the salad rests in the refrigerator for at least an hour.
- Taste as you go. The balance of lime, salt, and oil should be adjusted according to your preference. Don’t be afraid to add more of any component until it tastes just right.

Tuna Salad Recipe Variations
- Vegetables: Feel free to add extra vegetables to this salad recipe. You can add diced bell pepper for extra crunch, or cooked corn for a hint of sweetness. You can also serve it on top of lettuce leaves or throw in some chopped green beans!
- Herbs: If you don’t like cilantro, you can use fresh parsley or basil instead.
- Potatoes: For an extra colorful variation, you can use half regular potatoes and half purple potatoes.
- Yuca or Boiled Cassava: Replace the boiled potatoes with boiled cassava or yuca.
- Green plantains: Replace the boiled potatoes with boiled green plantains.
- Avocado: If you are an avocado lover, you can add some diced or sliced avocado on top right before serving.
- Mayonnaise: For a creamier variation, you can add mayo or a mix of mayo and yogurt.
