Causa Rellena con Pollo (Peruvian Layered Potato and Chicken)

PIn it

Introduction

Causa Rellena is a Peruvian layered potato cake bound with mayonnaise and filled with shredded chicken—it’s assembled cold and served chilled or at room temperature, making it ideal for meal prep or a composed appetizer plate. The dish relies on contrasting textures: creamy mashed potato, tender chicken filling, and bright garnish of hard-boiled egg and olives. You build it in a mold, chill it, then unmold and slice to reveal clean, distinct layers.

Recipe Details

• Prep Time: 35 minutes
• Cook Time: 25 minutes
• Total Time: 60 minutes (plus chilling time)
• Servings: 6 or more

Ingredients

• 10 medium potatoes (yellow, new, or red are a good choice)
• 1 pound of shredded boiled chicken meat
• 100 g mayonnaise
• 25 g butter
• 2 cloves garlic
• Salt
• Pepper
• Lettuce
• 3 hard boiled eggs
• Black olives

Instructions

1. Cook and peel potatoes. Allow to cool, then mash.
2. In a bowl combine the chicken, mayonnaise, onion, salt, and pepper.
3. Line a deep dish with plastic wrap, or place a molding cylinder on a plate.
4. Add the mashed potatoes to form a bed about 1 cm tall at the bottom.
5. Add a second layer of 1 cm of the chicken mixture evenly over the potato.
6. Top the chicken mixture with a final layer of potato, forming a sandwich of chicken inside two layers of potato.
7. Unmold or remove the cylinder.
8. Garnish with lettuce and mayonnaise.
9. Cut the hard boiled eggs in discs and place on top. Add black olives, if desired.
10. This dish can be served slightly cold.

Variations

Vegetarian version: Replace the shredded chicken with crumbled queso fresco mixed with finely diced roasted vegetables (bell peppers, zucchini, or carrots)—this keeps the creamy, savory filling but shifts the dish toward a lighter profile.

Spiced potato layer: Mix the mashed potatoes with a pinch of ground cumin or ají amarillo paste before forming the base layer for subtle Peruvian warmth without overpowering the chicken.

Add avocado: Layer thin slices of ripe avocado between the chicken mixture and the top potato layer for creaminess and a mild, buttery note that complements the mayo-based filling.

Seafood filling: Swap the chicken for canned or fresh lump crab meat or cooked shrimp mixed with the mayonnaise—this gives you a lighter, briny alternative that works well served cold.

Individual molded servings: Use small ring molds or ramekins to create individual portions instead of one large cake; this makes plating cleaner and allows guests to serve themselves.

Tips for Success

Chill the assembled causa for at least 2 hours before unmolding. This allows the potato and filling to set and hold their shape cleanly when you lift the mold or remove the plastic wrap.

Mash the potatoes while they’re still warm but not piping hot. Hot potatoes absorb butter and mash smoothly; cold potatoes become gluey. Add the butter to the warm potatoes for better absorption.

Don’t overfill the chicken layer. A thin, even 1 cm layer prevents the structure from collapsing when you unmold; thick pockets of filling create weak spots.

Use a bench scraper or offset spatula to spread each layer evenly. This ensures clean, uniform thickness and makes the unmolded causa look intentional rather than rustic.

Taste and season the chicken mixture generously before layering. Once assembled, the flavors don’t blend further, so under-seasoned filling reads as bland against the mild potato.

Storage and Reheating

Store the assembled causa in an airtight container in the refrigerator for up to 3 days. Keep it in the mold or loosely wrapped in plastic to protect the shape. This dish does not freeze well; the potato texture becomes grainy when thawed.

Causa Rellena is best served cold or at room temperature straight from the fridge—no reheating needed. If you prefer it slightly warmer, let it sit on the counter for 15–20 minutes before serving.

FAQ

Can I make the potato and chicken components ahead of time?

Yes. Cook and mash the potatoes up to 1 day ahead; store them in an airtight container in the fridge. Prepare the chicken filling separately and refrigerate. Assemble the causa no more than 4 hours before serving so the layers stay distinct.

What if I don’t have a molding cylinder?

Use a deep bowl or cake ring lined with plastic wrap, or even a clean can with the top and bottom removed. The plastic wrap makes unmolding much easier; press it gently against the sides as you build each layer.

The instructions mention onion in the chicken mixture, but onion isn’t in the ingredients list—should I add it?

No. Follow the ingredient list as written; the recipe works well without onion. If you’d like onion flavor, finely mince a small piece of raw onion or shallot and stir it into the chicken filling to taste.

Can I use leftover mashed potatoes?

Only if they were made fresh and refrigerated the same day. Leftover mashed potatoes that contain cream or milk may be too loose and won’t hold a clean layer. Freshly made mash gives you the best structure.
