Causa Rellena con Pollo (Peruvian Layered Potato and Chicken)

Introduction

Causa rellena is a Peruvian layered potato cake filled with seasoned chicken—it’s assembled cold and served in neat slices. The dish relies on waxy potatoes that hold their shape when mashed, a creamy chicken filling, and a careful layering technique. It works equally well as a light lunch, an appetizer, or a make-ahead dinner centerpiece.

Recipe Details

• Prep Time: 30 minutes
• Cook Time: 35 minutes
• Total Time: 65 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

Tuna filling: Swap the shredded chicken for canned tuna (drained well) mixed with the same mayonnaise, garlic, salt, and pepper. The result is lighter and works well for a cold lunch.

Roasted vegetable layer: Replace the chicken mixture with a layer of roasted and cooled vegetables (zucchini, bell pepper, eggplant), mixed with mayonnaise and garlic. This shifts the dish toward vegetarian while keeping the same structure.

Spiced potato base: Add 1 teaspoon of ground cumin and a pinch of cayenne to the mashed potatoes before layering. This deepens the flavor without changing technique or texture.

Avocado topping: Add sliced avocado alongside the hard-boiled eggs and olives on top of the unmolded causa for creaminess and richness.

Single-mold presentation: Instead of a deep dish, use a tall ring mold or cylinder to create individual portions—easier to serve and more elegant plating.

Tips for Success

Choose waxy potatoes: Yellow, new, or red potatoes hold their shape when mashed and give you a firmer, sliceable structure. Starchy russets will break down too much and fall apart when you cut the causa.

Cool the potatoes fully before mashing: Warm potatoes release more starch and become gluey. Room-temperature potatoes mash to a looser, more workable consistency.

Keep layers even and compact: Use an offset spatula or the back of a spoon to spread each layer smoothly to the edges. Uneven layers can collapse when you unmold or slice.

Don’t skip the plastic wrap or mold: This holds everything in place while you assemble and chill. Remove it gently right before serving, or leave it on the plate underneath for support.

Chill for at least 1 hour before unmolding: Cold causa holds together much better when you cut it. Warm or room-temperature layers will slide apart.

Storage and Reheating

Refrigerator: Cover the assembled causa with plastic wrap and store for up to 3 days. It actually tastes better after a few hours in the fridge, when the layers firm up.

Freezer: Not recommended. The potato texture breaks down when thawed, and the layers separate.

Serving: Serve cold or at room temperature. There is no need to reheat. If you prefer it slightly warmer, leave it on the counter for 30 minutes before serving, but don’t use heat.

FAQ

Can I assemble causa the night before?

Yes. Assemble it completely (including garnish if using eggs and olives), cover it tightly with plastic wrap, and refrigerate overnight. The flavors meld and the layers firm up, making it easier to slice cleanly.

What if I don’t have a molding cylinder?

A deep bowl, a loaf pan, or even a clean plastic container works just as well. Line it with plastic wrap and layer as directed. When unmolding, gently pull the plastic wrap to release the sides, then slide it onto a plate.

Can I use store-bought rotisserie chicken?

Yes. Shred it finely and mix with the mayonnaise and garlic as directed. This saves time on boiling and shredding, and the result tastes just as good.

Why does my causa fall apart when I cut it?

The dish was likely not chilled long enough, or the potato layers were too thin. Refrigerate for at least 1 hour (2 is better) before cutting, and make sure each potato layer is a full 1 cm thick for structural support.
