A little context

Causa is a staple of the Peruvian Andes, historically made with native yellow potatoes (papa amarilla) and often filled with tuna or chicken. Traditional recipes frequently call for vegetable oil and a touch of sugar to balance the heat of the aji pepper. We honor this heritage by sourcing authentic yellow potatoes and using aji amarillo paste, but we strictly eliminate seed oils and refined sugars, substituting them with cold-pressed extra-virgin olive oil and the natural sweetness of ripe fruit or dates if a touch of balance is needed.

Why this food

The longevity story

The dish leverages the resistant starch in cooled yellow potatoes to support gut microbiome diversity and lower the glycemic impact of the meal. Extra-virgin olive oil provides high concentrations of oleocanthal and oleuropein, potent anti-inflammatory polyphenols that protect cellular integrity. The inclusion of pasture-raised chicken ensures a superior amino acid profile and higher omega-3s compared to conventionally raised birds, while the black olives add monounsaturated fats and iron without the sodium spikes of processed deli meats.

Method

01
Poach the chicken
Place the pasture-raised chicken breast in a medium pot, cover with cold water, add a pinch of sea salt and a sprig of thyme. Bring to a bare simmer (do not boil vigorously) and cook for 12-15 minutes until the internal temperature reaches 74°C (165°F). Remove, let cool, and shred into bite-sized pieces. Reserve the cooking liquid for broth if desired.
02
Boil the potatoes
While the chicken cooks, place the peeled yellow potatoes in a large pot of salted cold water. Bring to a boil, reduce to a simmer, and cook for 20-25 minutes until a knife slides in effortlessly but the potatoes do not fall apart. Drain immediately and let them steam-dry for 5 minutes.
03
Rice the potatoes
Pass the hot potatoes through a potato ricer or food mill into a large mixing bowl. It is crucial to rice them while hot to ensure a smooth, lump-free texture. Do not use a food processor, which will make the potatoes gummy.
04
Season the base
While the potatoes are still warm, whisk together the extra-virgin olive oil, lime juice, aji amarillo paste, and sea salt. Pour this mixture over the riced potatoes and gently fold with a silicone spatula until fully incorporated. Taste and adjust seasoning. Let the mixture cool to room temperature, then refrigerate for 20 minutes to firm up.
05
Prepare the filling
In a separate bowl, combine the shredded chicken, diced avocado, sliced black olives, and rinsed red onion. Drizzle with 1 tablespoon of fresh lime juice and a tiny drizzle of extra-virgin olive oil. Toss gently to combine, being careful not to mash the avocado.
06
Assemble the Causa
If using a ring mold, place it on a serving plate. Spoon half of the potato mixture into the mold, pressing down firmly to create a flat, even layer. Spread the chicken and avocado filling over the potato base. Top with the remaining potato mixture, pressing down gently to seal. If not using a mold, layer in a glass dish: potato base, filling, potato top.
07
Chill and serve
Refrigerate the assembled Causa for at least 30 minutes to allow the flavors to meld and the layers to set. Carefully remove the ring mold if used. Garnish generously with fresh chopped cilantro just before serving.

Pro tips

✦Sourcing the right potato is non-negotiable: Look for 'Papa Amarilla' or 'Peruvian Yellow Potatoes' at a Latin market; if unavailable, Yukon Gold is the closest substitute, but Russets will fail.
✦Always rinse the red onion in ice water before adding it to the filling to remove the harsh bite while keeping the crunch.
✦Do not skip the cooling step for the potato base; warm potatoes will melt the avocado and make the dish mushy.
✦When selecting aji amarillo paste, read the label carefully: it should contain only peppers, oil (preferably olive), and salt—no sugar or seed oils.

Substitutions

pasture-raised chicken breast → wild-caught tuna or smoked trout (A traditional substitution that increases omega-3 intake; ensure the fish is flaked gently.)
black olives → green olives (manzanilla) (Provides a slightly different salt profile; ensure they are cured in brine, not oil.)
aji amarillo paste → fresh aji amarillo peppers (roasted and blended) (Make your own paste by roasting fresh peppers, removing seeds, and blending with a splash of EVOO.)

Storage

Store in an airtight glass container in the refrigerator for up to 3 days. The avocado may brown slightly; press plastic wrap directly against the surface to minimize oxidation. Do not freeze, as the potato texture will become grainy upon thawing.

What to serve with it

Sparkling water with a wedge of lime and fresh mint
Cold-brew green tea (unsweetened)
A glass of dry, organic Peruvian Torrontés or Sauvignon Blanc
Simple side salad of arugula and cherry tomatoes with EVOO dressing

FAQ

Can I use regular white potatoes?+

You can, but the texture and flavor will be different. White potatoes are starchier and lack the distinct buttery flavor and vibrant yellow color of the native varieties. If using white potatoes, add turmeric for color, but the taste will be less authentic.

Is this recipe low-carb?+

While potatoes are a starchy vegetable, this recipe uses resistant starch (from cooling) which lowers the glycemic impact. It is not strictly keto, but fits well within a whole-food, low-glycemic, Blueprint-aligned lifestyle when portioned correctly.

Can I make this ahead of time?+

Yes, the Causa actually benefits from being made 4-6 hours in advance as the flavors meld. However, add the fresh avocado and cilantro topping just before serving to prevent browning.
