Peruvian causa is a chilled, layered dish of mashed yellow potatoes seasoned with lime, oil, and ají amarillo, often filled with chicken, tuna, or vegetables. This version pairs the tangy, gently spicy potato with creamy avocado and a simple shredded-chicken salad for a fresh, sliceable centerpiece.
Ingredients
- 2½ lb (1.13 kg) Yukon Gold potatoes, similar in size if possible
- 1 lb (450 g) boneless, skinless chicken breast
- 6 cups (1.4 L) water, for poaching the chicken
- 1½ tsp (7.5 g) fine salt for the potatoes, plus 1 tsp (5 g) for the chicken poaching water
- ⅓ cup (80 ml) fresh lime juice, divided
- 2 tbsp (30 g) ají amarillo paste
- ¼ cup (60 ml) neutral oil, such as canola or sunflower oil
- ½ tsp (1 g) ground black pepper
- ½ cup (120 g) mayonnaise
- ¼ cup (35 g) finely chopped red onion
- 2 tbsp (8 g) finely chopped cilantro
- 1 large ripe avocado (about 200 g flesh), peeled, pitted, and sliced
- 1 tbsp (15 ml) lime juice, taken from the measured amount, to brush over the avocado
- ¼ cup (35 g) sliced pitted black olives, for garnish
- 6 lettuce leaves (about 60 g), for serving
Instructions
- Cook the potatoes. Scrub the potatoes and put them whole, unpeeled, in a large pot. Cover with cold water by about 1 inch (2.5 cm), bring to a boil, then lower the heat to maintain a steady simmer. Cook for 20–30 minutes, depending on size, until a knife slides into the center without resistance. Drain them well. While the potatoes cook, poach the chicken in the separate pot as described in the next step.
- Poach and cool the chicken. Put the chicken breast in a saucepan with the 6 cups water and 1 teaspoon salt. Bring just to a boil, then reduce the heat so the water simmers gently. Cook for about 15–20 minutes, turning once if needed for even cooking. Use a food thermometer to confirm the thickest part reaches the USDA FSIS safe minimum of 165°F (74°C). Lift the chicken out, shred it with two forks, and spread it in a shallow dish. Refrigerate it while you prepare the potatoes; let it cool for about 20 minutes before mixing it with mayonnaise.
- Make the causa potato mixture. When the potatoes are cool enough to handle, peel them. Pass them through a potato ricer or mash them thoroughly while still warm, working out any lumps. Stir in the ají amarillo paste, 2 tablespoons of the lime juice, the oil, salt, and black pepper. Mix until smooth and pliable, then taste. Add a little more lime juice or salt if needed. Let the potato mixture cool for about 20 minutes before assembling so it does not soften the avocado or warm the chicken filling.
- Prepare the filling. In a bowl, mix the cooled shredded chicken with the mayonnaise, red onion, cilantro, and the remaining 1 tablespoon lime juice. Taste and adjust the seasoning. The mixture should be creamy enough to spread but not loose or watery; if the chicken has released liquid, drain it before mixing. Keep the filling refrigerated until you are ready to assemble.
- Layer the causa. Lightly oil an 8-inch (20 cm) springform pan or place a ring mold on a serving plate. Press half of the potato mixture into an even layer across the bottom. Arrange the avocado slices over it and brush them with the reserved tablespoon of lime juice if you have not already done so. Spread the chicken mixture evenly on top, then finish with the remaining potato, pressing gently to make a level surface. Avoid compressing the layers hard, which can make the potato dense.
- Chill and serve. Cover the pan and refrigerate the causa for 30 minutes so the layers firm up. Run a thin knife around the edge, release the springform or lift away the ring, and garnish with sliced olives. Cut into wedges with a sharp knife and serve each portion on a lettuce leaf.
Tips
- Choose a potato that mashes smoothly. Peru’s traditional papa amarilla, or yellow potato, gives causa its vivid color and soft texture, but it can be difficult to find outside Latin American markets. Yukon Gold potatoes are a practical substitute; they make a slightly less intensely yellow causa but mash smoothly and hold their shape. Avoid waxy potatoes, which can turn gluey when mashed.
- Use ají amarillo paste carefully. This Peruvian yellow chile paste brings fruity flavor and moderate heat as well as color. It is sold in jars or tubes at Latin American groceries and some larger supermarkets. If unavailable, use a mild yellow chile paste or a small amount of minced yellow chile with a pinch of paprika; the flavor will be less distinctive. Start with less if your paste is especially hot.
- Keep the potato mixture supple, not wet. Rice or mash the potatoes while warm, and add the oil and lime gradually. Different potatoes absorb liquid differently. The finished mixture should be soft enough to press into a layer but firm enough to hold a clean edge when sliced. If it feels dry or cracks, work in a teaspoon of oil or lime juice at a time; if it is loose, let it cool a little longer.
- Cool the components before building the layers. Warm potato can make avocado mushy and can raise the temperature of the chicken-and-mayonnaise filling. Use a shallow dish to cool chicken quickly, and refrigerate the filling while you work. For the neatest slices, chill the completed causa for the full 30 minutes and wipe the knife between cuts.
Serving Suggestions
Serve causa cold or cool, not hot, as a first course, a light lunch, or part of a larger Peruvian-style meal. The lettuce leaf under each wedge adds a crisp, fresh contrast, while the olives give a salty accent. A simple tomato and red onion salad, extra lime wedges, or a little chopped cilantro on the side also works well. Because the potato, chicken, and avocado make the dish satisfying, modest wedges are usually enough when it is served alongside other food.
For a buffet, make one large ring-molded causa and cut it at the table, or assemble individual portions in small ramekins for a tidy presentation. Keep it refrigerated until serving and set out only what guests are ready to eat. The layers are soft, so use a thin, sharp knife and lift each piece with a cake server or broad spatula rather than trying to pick it up by hand.
Variations
Tuna causa: Replace the cooked chicken with about 2 cups (300 g) drained canned tuna. Mix it with the mayonnaise, onion, cilantro, and lime as directed. Tuna is a common alternative filling, and it makes the dish quicker to assemble; check that the tuna is well drained so the layers stay firm.
Vegetarian causa: Leave out the chicken and layer in cooked green beans, corn, or finely chopped cooked vegetables with the avocado. You can also use a chickpea salad bound with mayonnaise. Season the filling well, because the potato layers are mild apart from the lime and chile.
More or less heat: Adjust the ají amarillo paste to taste, but keep enough in the potatoes to give them their characteristic chile flavor. For a milder result, begin with 1 tablespoon (15 g); for a more pronounced chile taste, add another teaspoon after tasting. If using a substitute chile, add it gradually because its heat can differ from jarred ají amarillo paste.
Individual portions: Press the same layers into small ramekins or food rings, dividing the ingredients evenly. Chill them for 30 minutes as for the large causa, then unmold onto lettuce-lined plates. Smaller portions are convenient for serving, though the avocado and chicken still need to be kept cold.
Storage and Reheating
Refrigerate assembled causa within 2 hours of making it, covered tightly or in an airtight container. For the best texture and color, serve it within 24 hours: avocado can darken, and the potato layers gradually lose their clean, firm texture. It can be kept refrigerated for up to 2 days; discard it sooner if it has been left at room temperature for more than 2 hours. If you prepare the chicken filling ahead, store it separately in the refrigerator and use it within 3–4 days of cooking.
Causa is designed to be served chilled, so do not reheat the assembled dish; heating will soften the avocado and mayonnaise filling. If you have leftover chicken filling that you want to serve warm in another dish, reheat it separately to 165°F (74°C), then serve it without the cold potato and avocado layers. Do not freeze the assembled causa, since thawing makes the potato and avocado watery and uneven.
Frequently Asked Questions
What does causa mean in this dish?
The name is associated with causa limeña, a Peruvian preparation of seasoned potato served in layers or molded portions. The potato base is the defining feature; fillings and garnishes vary by cook and region, so chicken is one popular version rather than the only one.
Can I make causa without ají amarillo?
Yes. A mild yellow chile paste is the closest practical stand-in, though the flavor will not be identical. If using fresh yellow chile, mince it finely and add a small amount at a time. The recipe will still have its lime-seasoned potato character without the paste, but it will be less fruity and less traditionally flavored.
Can I prepare the components ahead?
Yes. Cook and shred the chicken and refrigerate the filling separately, and make the potato mixture the same day if possible. Assemble the causa shortly before serving or up to a day ahead. Keeping the avocado protected between the potato and chicken layers helps limit browning, but the cut avocado is still best when fresh.
Why is my causa sticky or difficult to slice?
Overworking potatoes can make them gummy, especially if they are mashed in a food processor. Use a potato ricer or hand masher and stop as soon as the mixture is smooth. A very warm potato base, wet chicken filling, or insufficient chilling can also blur the layers; cool the ingredients, drain the filling, and chill the assembled dish before cutting.
Can I use leftover cooked chicken?
Yes. Use about 2 cups (300 g) of cooked, shredded chicken in place of the raw breast, and skip the poaching step. Keep the chicken refrigerated while preparing the other ingredients, then mix it with the mayonnaise and seasonings. If reheating leftover chicken before using it in another preparation, heat it to 165°F (74°C); for causa, use it cold and assemble promptly.
