Causa rellena is a chilled, layered Peruvian dish made with seasoned yellow potatoes, lime, and ají amarillo, often filled with chicken, tuna, or vegetables. This version pairs a soft, citrusy potato layer with creamy chicken and avocado; its make-ahead assembly and bright flavors make it a practical centerpiece or shared starter.
Ingredients
- 3 lb (1.36 kg) yellow-fleshed potatoes, such as Yukon Gold, scrubbed; this makes about 6 to 7 cups (1.4 to 1.7 L) mashed potato
- 1 lb (450 g) boneless, skinless chicken breast, which yields about 2 cups (280 g) shredded chicken
- 4 cups (950 ml) water for poaching the chicken
- 1/2 cup (120 ml) fresh lime juice, divided
- 1/3 cup (80 ml) neutral vegetable oil, such as sunflower or canola oil
- 1/4 cup (60 g) ají amarillo paste
- 1 1/2 tsp (9 g) fine salt for the potato mixture, plus 1/2 tsp (3 g) for the chicken and filling
- 1/2 tsp (1 g) ground black pepper, divided
- 1/3 cup (75 g) mayonnaise
- 1/4 cup (35 g) finely minced red onion
- 2 medium ripe avocados (about 10 oz / 280 g whole, or 1 cup / 225 g sliced flesh)
- 1 tsp (5 ml) extra lime juice and a pinch of salt for the avocado
- 2 large eggs (about 3.5 oz / 100 g), optional, hard-boiled until the yolk and white are firm
- 8 black olives (about 1 oz / 30 g) and 2 tbsp (8 g) chopped parsley, optional, for garnish
Instructions
- Cook the potatoes. Put the whole potatoes in a large pot and cover with cool water by about 1 inch (2.5 cm). Bring to a boil, then reduce the heat to maintain a steady simmer. Cook for 20 to 30 minutes, depending on their size, until a thin knife slides easily into the center. Drain them well. Let them sit just until cool enough to handle, then peel while still warm; the skins should slip off with a small knife or your fingers.
- Poach the chicken while the potatoes cook. Place the chicken breast and 4 cups (950 ml) water in a saucepan. Bring the water to a gentle simmer and cook for about 15 to 20 minutes, turning the chicken once if it is not fully submerged. Check the thickest part with a food thermometer: USDA FSIS sets 165°F (74°C) as the safe minimum internal temperature for poultry. Transfer the chicken to a clean plate and let it cool for about 15 minutes, then shred it finely with two forks. Do not use the raw-chicken poaching liquid in the filling.
- Season and mash the potato. While the potatoes are still warm, press them through a potato ricer or mash thoroughly until smooth, with no large lumps. A ricer gives the lightest texture; a regular masher works as well. Stir in the ají amarillo paste, 1/3 cup (80 ml) of the lime juice, the vegetable oil, 1 1/2 teaspoons (9 g) salt, and 1/4 teaspoon (0.5 g) black pepper. Mix until evenly colored and supple. Taste after mixing, then add some or all of the remaining lime juice to balance the potato’s richness. Let the mash cool until it is no longer warm before layering.
- Make the chicken filling. In a bowl, combine the shredded chicken, mayonnaise, minced red onion, 1 tablespoon (15 ml) of the remaining lime juice, 1/2 teaspoon (3 g) salt, and the remaining 1/4 teaspoon (0.5 g) pepper. Stir until the chicken is evenly coated. It should hold together when spooned but remain moist; add another teaspoon of mayonnaise if the chicken seems dry. Taste and adjust the salt or lime if needed.
- Prepare the avocado. Peel and pit the avocados, then cut the flesh into slices about 1/4 inch (6 mm) thick. Toss gently with 1 teaspoon (5 ml) lime juice and a pinch of salt. The acid slows browning, but prepare the avocado close to assembly for the freshest color and flavor.
- Layer the causa. Lightly oil an 8-inch (20 cm) square dish, or line it with parchment with enough overhang to help lift out the finished dish. Divide the potato mixture into three portions. Press one portion into an even layer in the dish, smoothing it to the edges without compacting it hard. Arrange the avocado slices over the potato, then spread the chicken filling on top. Add the remaining potato in two portions, smoothing the second layer over the filling and the last portion across the top. A damp spatula or clean hands make the potato easier to spread without sticking.
- Chill, cut, and garnish. Cover the dish and refrigerate for at least 30 minutes so the layers firm up enough to slice. Cut into eight portions with a sharp knife, wiping the blade between cuts for tidy edges. If using, garnish each piece with a quartered hard-boiled egg, an olive, and a little parsley. Serve cold or cool, not warmed.
Tips
- Choose potatoes that mash smoothly. Yellow potatoes are a convenient choice because they become creamy without much added fat. If you use a starchier potato, handle it gently after mashing; vigorous mixing can make the texture gluey.
- Adjust ají amarillo to taste. Ají amarillo paste gives causa its characteristic fruity, gently spicy flavor and golden color. Paste varies in heat, so start with a little less if yours is unfamiliar and add more after tasting. If you cannot find it, use 2 tablespoons (30 g) yellow bell pepper purée plus 1 small seeded jalapeño (about 15 g), finely minced. This substitute is less fruity and may taste sharper, so add it gradually.
- Keep the potato mixture tender. Rice or mash the potatoes while warm, then stir in the oil and lime until smooth. Avoid a food processor or blender: the blades can overwork the starch and turn the mash elastic. If the mixture cracks while spreading, work in 1 teaspoon (5 ml) oil or lime juice at a time.
- Make clean, stable layers. Cool the potato before assembly, and spread each layer evenly rather than pressing down hard. Chill the completed dish before cutting. For easier serving, use a sharp knife and clean it between slices; a firm but gentle cut keeps the filling from squeezing out.
Serving Suggestions
Serve causa rellena as a cool lunch, a substantial first course, or part of a Peruvian-inspired meal. The recipe makes eight generous portions; for a buffet or appetizer spread, cut each portion in half into smaller squares. Arrange the pieces on a platter with the optional egg, olives, and parsley, and offer lime wedges at the table for anyone who wants extra brightness.
Because the dish already includes potatoes, chicken, and avocado, pair it with something crisp and simple: a green salad dressed with lime, sliced tomatoes, or lightly dressed lettuce. It also fits well alongside grilled vegetables or a bowl of soup. Keep accompaniments mild so the citrus and ají amarillo in the causa remain easy to taste.
Variations
Chicken is one familiar filling, but causa has many household and regional versions rather than a single fixed combination. For a tuna version, replace the poached chicken with 2 cups (280 g) drained canned tuna and mix it with the same mayonnaise, onion, lime, salt, and pepper. Since canned tuna is already seasoned, taste before adding the full amount of salt.
For a vegetarian filling, use 1 1/2 cups (240 g) cooked, cooled green peas and 1 cup (150 g) finely diced cooked carrot in place of the chicken. Fold them with the mayonnaise and onion, or layer them with the avocado. For a seafood version, use cooked shrimp instead of chicken; keep it chilled and chop larger shrimp into bite-size pieces. A simpler presentation is to shape individual rounds with a ring mold, layering the same potato, avocado, and filling in each one.
Storage and Reheating
Refrigerate the assembled causa within 2 hours of making it, covered tightly, and keep it at 40°F (4°C) or colder. For best texture and the least avocado browning, serve it within 1 to 2 days; if needed, properly chilled leftovers can generally be kept for 3 to 4 days. The avocado may darken and the potato may become firmer over time, even when the food has been handled safely. Do not leave servings at room temperature for more than 2 hours, or more than 1 hour when the temperature is above 90°F (32°C).
Causa rellena is intended to be served chilled or cool, so reheating is not recommended: heat can soften the layers and make the avocado unpleasant. If you have leftover chicken filling that was stored separately, reheat that filling to 165°F (74°C) if you plan to eat it warm, but do not reheat the assembled causa. Freezing is also not ideal because potatoes and avocado can turn watery or grainy after thawing.
Frequently Asked Questions
What does causa rellena mean?
“Causa rellena” is commonly translated as “stuffed causa.” It refers to a Peruvian preparation in which seasoned mashed potato is layered around a filling, often chicken, tuna, or vegetables. The name and exact ingredients can vary in family and regional cooking.
Can I make causa rellena ahead?
Yes. You can cook and shred the chicken and prepare the seasoned potato a day ahead, storing them in separate covered containers in the refrigerator. For the freshest avocado and neatest layers, assemble the dish on the day you plan to serve it, then chill it for at least 30 minutes before cutting.
Can I use regular potatoes instead of yellow potatoes?
Yes. Russet potatoes work, although they are starchier and can become sticky if overmixed. Cook them whole, drain them thoroughly, rice or mash them while warm, and fold in the seasonings just until smooth. If the mash feels dry, add a small amount of oil or lime juice rather than extra water.
How spicy is causa rellena?
It is usually mildly to moderately spicy, but the heat depends on the ají amarillo paste. Start with 3 tablespoons (45 g) if you want a gentler flavor, then taste and add more before assembling. The lime, potato, and creamy filling balance the chile, but they do not remove its heat.
Why is my potato layer difficult to spread?
The mash may have cooled too much, be too dry, or have been compacted. Let it sit briefly at room temperature if it is stiff, then work in a teaspoon of oil or lime juice at a time. Spread it with a damp spatula, using light pressure so the layers stay tender.
