Causa Rellena con Pollo (Peruvian Layered Potato and Chicken)

Introduction

Causa rellena is a classic Peruvian dish of layered mashed potato, shredded chicken, and creamy filling—it’s assembled cold and served as a stunning appetizer or light main. The potato acts as both structure and base, while the chicken mixture in the center stays moist and flavorful. This works equally well for a dinner party or meal prep, and the assembly is straightforward once your components are ready.

Recipe Details

• Prep Time: 45 minutes
• Cook Time: 35 minutes
• Total Time: 80 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

• 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

Add ají amarillo paste: Mix 1–2 teaspoons of ají amarillo (Peruvian yellow chili paste) into the mashed potato layer for authentic heat and color without changing the structure.

Use a different protein: Substitute the chicken with the same weight of canned tuna, flaked and drained, or shredded cooked turkey for a lighter variation.

Layer in individual servings: Instead of one large mold, use small ramekins or ring molds to create individual portions—easier to unmold and more elegant for plating.

Add avocado: Fold thin avocado slices into the chicken mixture or place them as a thin layer between the chicken and top potato for richness and a creamy texture contrast.

Incorporate corn: Mix fresh or frozen corn kernels into the chicken filling to add sweetness and a subtle textural contrast.

Tips for Success

Cool your potatoes completely before mashing: Hot potatoes absorb seasoning unevenly and become gluey; letting them cool also prevents the mayonnaise from breaking when you mix it in.

Season the chicken mixture boldly: The potato layers are relatively neutral, so taste the chicken filling and adjust salt and pepper to your preference—it carries the flavor of the whole dish.

Use plastic wrap for easy unmolding: Lining your mold prevents sticking; gently peel the wrap away from the sides before inverting onto your serving plate.

Keep layers thin and even: Aim for exactly 1 cm per layer so the structure holds together when you cut it and each bite has all three components.

Chill before serving if time allows: 30 minutes in the fridge sets the layers and makes the dish easier to cut cleanly; it also develops the flavors.

Storage and Reheating

Refrigerator: Store the assembled causa in an airtight container for up to 3 days. Keep it covered to prevent the potato from drying out.

Freezer: Causa does not freeze well—the potato texture becomes grainy and the layers separate when thawed.

FAQ

Can I prepare the components ahead of time?

Yes. Cook and mash the potatoes up to 2 days ahead and store them covered in the fridge. Boil the chicken and prepare the filling 1 day in advance. Assemble the final dish no more than 4 hours before serving to keep the potato layers from absorbing too much moisture.

What if the layers don’t hold together when I cut?

Your mashed potato may be too wet or insufficiently cooled. Next time, drain excess moisture from the potatoes after cooking and let them cool fully before mashing. You can also refrigerate the assembled dish for 30 minutes before unmolding to help the layers set.

Can I use a different mold or container?

Absolutely. A loaf pan, springform cake pan, or any deep dish lined with plastic wrap works; a cylindrical mold simply produces the classic round presentation. Whatever you use, make sure the sides are straight so the layers release cleanly.

Is there a dairy-free option for the filling?

You can replace the mayonnaise with an oil-based or plant-based alternative in the same amount. The texture and binding will be slightly different, but the dish will still hold together and taste good.
