Causa Rellena con Pollo (Peruvian Layered Potato and Chicken)

Pin it

Introduction

Causa rellena is a Peruvian layered potato cake with a tender chicken salad center, built in a mold and unmolded to reveal clean, distinct strata. Yellow potatoes mash into a silky base that holds together without additional binders, creating structure sturdy enough to slice cleanly. This is a showpiece dish that looks composed and elegant but requires only basic cooking skills and one bowl of mixing.

Recipe Details

• Prep Time: 30 minutes
• Cook Time: 40 minutes
• Total Time: 70 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

Swap the chicken for canned tuna: Use the same weight of drained canned tuna in place of boiled chicken. The result will be slightly less rich but saves cooking time and works well for a lighter weeknight version.

Add fresh lime juice to the potato layer: Fold 2 tablespoons of fresh lime juice into the mashed potatoes before layering. This brightens the earthiness of the potatoes and is traditional in some Peruvian preparations.

Layer in avocado slices: Place thin avocado slices as a fourth layer between the chicken mixture and the top potato layer. This adds creaminess and a mild, buttery flavor that complements the chicken salad.

Use a ring mold instead of a dish: Instead of lining a deep dish, set a stainless-steel ring mold on a plate lined with plastic wrap. This makes unmolding easier and gives you a more defined cylinder shape.

Garnish with sliced red onion and cilantro: Replace or supplement the lettuce with thinly sliced red onion and fresh cilantro leaves for a sharper, more herbaceous top layer.

Tips for Success

Mash the potatoes while they’re still warm: Warm potatoes mash to a smoother, more cohesive texture. Once cold, they become dense and lumpy. Cool just enough to handle, then mash immediately.

Press each layer firmly as you build: Use the back of a spoon or an offset spatula to pack each layer gently but firmly against the one below. This ensures the layers stay intact when you unmold and slice.

Chill the assembled causa before unmolding: Refrigerate the molded dish for at least 1 hour before removing the mold. Cold causa holds its shape much better during unmolding and slicing than room-temperature causa.

Taste the chicken mixture before layering: The chicken salad should be well-seasoned and slightly salty—it’s sandwiched between two mild potato layers, so it needs to carry flavor on its own.

Use a sharp, wet knife to slice: A damp blade prevents the potato from sticking and tearing. Wipe the knife clean between cuts for neat, defined portions.

Storage and Reheating

FAQ

What if my potato mash is too wet and won’t hold its shape? Yellow potatoes are naturally starchy and should mash into a cohesive mass. If your mash is wet, you likely overworked it or boiled it too long. Boil potatoes just until a fork pierces them easily; avoid a mushy texture. If the mash is already too wet, fold in a tablespoon or two of the butter to help it bind together.

What goes in the chicken mixture if the recipe doesn’t list onion in the ingredients? The instructions mention onion but it’s not listed in the ingredients. Use 1 small finely diced onion or 2 tablespoons of minced white onion in the chicken salad for a traditional flavor profile.
