Ecuador's take on the Andean classic — boiled potatoes blanketed in a creamy, golden ají amarillo and fresh cheese sauce, served as a starter with lettuce, egg and olives.
Papa a la huancaína is originally a Peruvian dish from the sierra city of Huancayo, but it has been adopted and adapted across the Andes, and Ecuador's version reflects local ingredient preferences while maintaining the essential character: boiled potatoes in a poured, vivid yellow cream sauce made from ají amarillo chile, fresh white cheese, crackers and oil that is simultaneously spicy, creamy, tangy and rich. In Ecuador, the sauce is typically made with ají amarillo (or the local ají de color as a milder substitute), queso fresco, a little lime juice and crackers or bread to bind and thicken the sauce. The yellow color comes entirely from the ají amarillo — a naturally vivid orange-yellow chile that contributes both heat and a distinctive fruity flavor unlike any other pepper. The sauce is blended until completely smooth and poured generously over sliced boiled potatoes arranged on a bed of lettuce. The garnish — hard-boiled egg halves, black olives, sliced radish and fresh cilantro — transforms what is essentially dressed potatoes into a composed appetizer of striking visual appeal. It is served cold or at room temperature, making it ideal as a starter or side dish at Ecuadorian Sunday lunches and celebrations.
Serves 4
Boil potatoes in well-salted water until completely tender — a thin knife should pass through without resistance. Drain, peel while warm and slice into 1 cm rounds. Set aside to cool.
Blend ají amarillo, queso fresco, crackers, garlic, oil, lime juice and salt in a blender until completely smooth. The sauce should pour like a thick cream.
If the sauce is too thick, add oil or evaporated milk 1 tbsp at a time. If too thin, add more crackers.
Taste the sauce for salt and acidity. The ají amarillo heat intensifies as the sauce sits — if you prefer milder, use fewer chiles or more queso to dilute.
Arrange lettuce leaves on a platter or individual plates. Lay sliced potatoes on the lettuce. Pour the sauce generously over the potatoes. Garnish with hard-boiled egg halves, black olives and cilantro.
Use waxy potatoes (not floury) — they hold their shape after boiling and slicing without crumbling.
Ají amarillo paste (jarred) is available in Latin grocery stores and is easier to use than fresh — use 2–3 tbsp in place of fresh chiles.
Classic Peruvian version: use evaporated milk instead of oil for a richer, creamier sauce.
Add 1 tbsp turmeric to boost the golden color if ají amarillo is unavailable.
The sauce keeps refrigerated up to 3 days and thickens as it chills — thin with a little water or milk before serving. Store boiled potatoes and sauce separately.
Papa a la huancaína originated in Huancayo, Peru, in the late 19th century, reportedly served to railway workers building the Lima-Huancayo line. The dish traveled with Andean trade and migration throughout the southern Andes, and Ecuador adopted it — with characteristic regional modifications — into its own culinary repertoire. Ecuador's version typically uses less evaporated milk (a Peruvian kitchen staple) and more fresh lime juice, reflecting coastal Ecuador's citrus abundance.
Ají amarillo paste in jars is available at most Latin American grocery stores and online — it is far easier to find than fresh peppers. As a substitute, combine equal parts red bell pepper and jalapeño for similar heat and fruitiness, though the distinctive flavor of ají amarillo is irreplaceable.
Yes — the sauce keeps refrigerated up to 3 days. It thickens as it chills. Stir in 1–2 tbsp water or milk when you take it out and blend briefly to restore smooth consistency.
