Ocopa arequipeña is one of Arequipa’s most iconic dishes. It is a creamy, fragrant sauce made with dried ají mirasol peppers, huacatay, toasted peanuts, fresh cheese, crackers, and evaporated milk. It is traditionally served over boiled potatoes with hard-boiled eggs, black olives, and lettuce.
Its bold flavor and distinctive greenish color set it apart from other Peruvian sauces. Ocopa is strongly connected to Arequipa’s picanterías, traditional eateries that play an important role in the region’s culinary identity. In 2025, ocopa arequipeña received Peru’s national Traditional Specialty Guaranteed recognition.

Arequipa Ocopa
- Prep Time: 25 minutes
- Cook Time: 35 minutes
- Total Time: 1 hour
- Yield: 6
- Category: Main Course
- Cuisine: Peruvian
Ingredients
- 1 kg yellow potatoes or starchy white potatoes (6 medium potatoes)
- 4 eggs
- 60 ml vegetable oil (¼ cup)
- 100 g red onion, cut into chunks (1 small onion)
- 12 g peeled garlic (3 cloves)
- 80 g dried ají mirasol peppers, seeded and deveined (4 medium peppers)
- 30 g fresh huacatay leaves (1 packed cup)
- 100 g unsalted toasted peanuts (¾ cup)
- 250 g fresh cheese or queso serrano, crumbled (2 cups)
- 100 g saltine crackers or plain water crackers (1½ cups)
- 240 ml evaporated milk (1 cup)
- 5 g salt (1 teaspoon)
- 2 g ground black pepper (½ teaspoon)
- 80 g pitted black olives (½ cup)
- 100 g lettuce leaves (1 small head)
Preparation
- Cook the potatoes and eggs, wash the potatoes and cook them with their skins on in a pot of water until tender when pierced, about 25 to 35 minutes depending on their size. In a separate pot, boil the eggs for 10 minutes once the water reaches a boil. Cool, peel, and halve the eggs. Peel the potatoes while warm and cut them into thick slices.
- Sauté the sauce ingredients, heat the oil in a skillet over medium heat and add the red onion, garlic, and ají mirasol. Cook for 6 to 8 minutes, stirring often, until the onion is soft and the peppers are fragrant without browning. Add the huacatay during the final minute, then remove the skillet from the heat.
- Blend the ocopa sauce, add the sautéed ingredients, toasted peanuts, cheese, crackers, evaporated milk, salt, and pepper to a blender. Blend until smooth, thick, and creamy. If it is too thick, add 15 to 30 ml more evaporated milk; if it is too thin, add one or two crackers and blend again.
- Plate and serve, arrange lettuce leaves on serving plates and place the sliced potatoes on top. Spoon a generous amount of ocopa sauce over the potatoes, then garnish each serving with half a hard-boiled egg and black olives. Serve at room temperature or slightly chilled.
Chef’s Tips
- Use dried ají mirasol, which is dried yellow ají pepper, for the most authentic depth of flavor.
- Wash and dry the huacatay carefully; its herbal aroma is essential to traditional ocopa.
- Blend the sauce in short pulses to prevent it from becoming overly warm.
- Add evaporated milk gradually, because the sauce should coat the potatoes without becoming runny.
- You can make the sauce several hours ahead and refrigerate it. Let it sit for 15 minutes before serving so it becomes creamy again.

In Arequipa, ocopa can also appear with egg, shrimp, and other picantería-style accompaniments. The best-known version is served with boiled potatoes, hard-boiled eggs, black olives, and lettuce, while the huacatay, ají mirasol, peanut, and cheese sauce remains its defining feature.

Frequently Asked Questions
Ocopa has a more herbal, toasted flavor because it includes huacatay, peanuts, and dried ají mirasol. Huancaína sauce is generally made with fresh ají amarillo, cheese, and milk, without huacatay’s intense aroma or the nutty flavor of peanuts. Both sauces are served with potatoes, but they belong to different regional Peruvian traditions.
Fresh yellow ají can add heat and color, but dried ají mirasol is the best option for traditional ocopa. Drying concentrates the pepper’s flavor and gives the sauce its distinctive depth. You can combine it with a small amount of fresh yellow ají, but do not replace the dried pepper entirely.
Keep it in an airtight container in the refrigerator for up to two days. Before serving, stir it well and let it stand at room temperature for a few minutes. If it becomes too thick after chilling, add a small amount of evaporated milk and mix until the sauce is creamy again.
No. Traditional ocopa is served at room temperature or slightly chilled over cooked potatoes. The sauce may still be warm after blending, but it does not need to be boiled or reheated before serving. This helps preserve the aroma of huacatay and the creamy texture created by the cheese and peanuts.
