Causa Rellena con Pollo (Peruvian Layered Potato and Chicken)

Introduction

Causa rellena is a Peruvian layered dish built in three clean stages: mashed potato base, seasoned chicken filling, and potato cap, all unmolded and garnished. It works cold or at room temperature, making it ideal for meal prep, potlucks, or a composed lunch plate that looks more refined than its simple ingredient list suggests.

Recipe Details

• Prep Time: 30 minutes
• Cook Time: 25 minutes
• Total Time: 55 minutes
• 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

With avocado: Layer thin slices of ripe avocado between the chicken filling and the top potato layer for creaminess and mild richness that complements the mild chicken.

Spiced chicken filling: Mix hot sauce, cumin, or smoked paprika into the chicken-mayonnaise mixture to add depth and warmth to the filling.

Add roasted vegetables: Fold roasted diced bell peppers, corn, or peas into the chicken mixture for texture and color contrast.

Cheese layer: Crumble queso fresco or feta between the chicken and top potato layer for tang and a slight textural break.

Herb garnish: Top the finished dish with fresh cilantro or parsley instead of (or in addition to) lettuce for brightness.

Tips for Success

Cool the potatoes completely before massing. Warm potatoes release steam and can become gluey; cooled potatoes mash to a smooth, workable consistency that layers cleanly.

Use a plastic wrap–lined bowl or a molding ring. This makes unmolding foolproof—the wrap peels away cleanly and holds the layers together during the invert.

Keep each layer to exactly 1 cm. Use a ruler or the side of a knife to check; uneven layers will topple when unmolded, and thin layers ensure the dish holds its shape.

Season the chicken mixture well. Because potatoes are bland, the filling must carry enough salt and pepper to flavor the whole bite.

Slice the hard-boiled eggs while the dish is still cool. Warm eggs become difficult to slice cleanly; cold eggs cut with sharp, thin discs that stay intact on top.

Storage and Reheating

Store the unmolded causa in an airtight container in the refrigerator for up to 3 days. It does not freeze well—the potato texture becomes grainy and the mayonnaise-based filling can separate.

FAQ

Can I assemble this ahead of time?

Yes. Build the causa up to 4 hours before serving, cover it loosely with plastic wrap, and refrigerate. Unmold just before garnishing and serving so the layers don’t absorb excess moisture.

What if I don’t have a molding cylinder?

A deep bowl or small loaf pan lined with plastic wrap works equally well. Invert the bowl onto a plate, peel away the wrap, and the shape will hold.

Can I make the chicken filling without mayonnaise?

Not without changing the dish significantly. Mayonnaise binds and moistens the filling; without it, the chicken will be dry and crumbly, and the layers may collapse during unmolding. Sour cream or Greek yogurt are poor substitutes here because they’re too wet and will seep into the potato layers.

Why is there “onion” in the ingredients list when potatoes and garlic are the only aromatics mentioned?
