Crab causa limeña is an elegant Peruvian variation of classic causa: chilled layers of yellow potato seasoned with ají amarillo, lime juice, and oil, filled with creamy crabmeat and avocado. The dish balances the velvety potato base with the delicate, lightly tangy flavor of crab.
Causa is an essential part of Lima’s culinary tradition and can be filled with poultry, seafood, avocado, or vegetables. Crab causa is especially popular as a cold appetizer for family lunches, celebrations, and Peruvian-style gatherings.

Ingredients
- 900 g cooked, peeled yellow potatoes
- 60 ml fresh lime juice (4 tablespoons)
- 30 ml vegetable oil (2 tablespoons)
- 60 g ground ají amarillo or ají amarillo paste (4 tablespoons)
- 8 g salt (1½ teaspoons)
- 340 g cooked, cleaned crabmeat (12 ounces)
- 60 g mayonnaise (4 tablespoons)
- 30 ml fresh lime juice (2 tablespoons)
- 1 g cayenne pepper (¼ teaspoon)
- 200 g sliced avocado (1 large avocado)
- 15 g chopped fresh parsley (¼ cup)
- 80 g lettuce leaves (8 large leaves)
Preparation
- Mash the potatoes, cook the potatoes until tender, peel them while still warm, and press them through a potato ricer. Let the mashed potatoes cool to room temperature so they remain light and easy to shape.
- Season the potato mixture, add 60 ml of lime juice, vegetable oil, ají amarillo, and salt. Mix with clean hands or a spatula until the mixture is smooth, even, and moldable. Taste and adjust the salt if needed.
- Make the crab filling, check the crabmeat carefully for any shell fragments, then combine it with mayonnaise, 30 ml of lime juice, and cayenne pepper. Fold gently so the crab remains light and retains some texture.
- Assemble the causa, spread half of the potato mixture into a small rectangular dish or four individual molds. Press gently into an even layer, arrange the avocado slices over it, and spread the crab filling on top.
- Finish and chill, cover with the remaining potato mixture and smooth the surface with a lightly dampened spatula. Refrigerate for 30 minutes so the causa firms up and is easier to slice or unmold.
- Garnish and serve, place the causa over fresh lettuce leaves, sprinkle with chopped parsley, and serve chilled. Add a small amount of mayonnaise to each portion just before serving, if desired.
Chef’s Tips
- Use Peruvian yellow potatoes whenever possible for the most authentic creamy texture.
- Do not use a blender or electric mixer for the potatoes, as they can turn gummy.
- Drain the crabmeat thoroughly before mixing it with mayonnaise.
- Slice the avocado shortly before assembling to keep it fresh and bright.
- Keep the finished causa covered in the refrigerator so the potato layer does not dry out.
Traditional Variations
In Peru, causa is also commonly filled with chicken, tuna, seafood, crabmeat, avocado, or vegetables. The classic potato base remains the same: yellow potatoes, ají amarillo, lime juice, oil, and salt.
How to Serve
Serve crab causa limeña chilled as an appetizer, either in neat rectangular portions or individual molds. Plate it over fresh lettuce leaves and finish with chopped parsley. It pairs well with chilled chicha morada, ají amarillo sauce, or a fresh green salad.
A Little History
Causa limeña has pre-Hispanic roots connected to yellow potatoes and ají peppers. Lime was incorporated later, helping create the chilled, vibrant dish that became a defining part of Lima’s food culture.
Crab causa preserves that traditional potato base while showcasing the seafood fillings that have made causa one of Peru’s most adaptable and beloved appetizers.
Frequently Asked Questions
Use cooked, cleaned, and well-drained crabmeat with a mild flavor and firm texture. It should be free of shell fragments and not overly seasoned. Fresh crabmeat gives the best result, but good-quality refrigerated pasteurized crabmeat can also work well when fresh crab is not available.
Yes. You can assemble it several hours ahead and keep it covered in the refrigerator. Add the parsley and lettuce shortly before serving so they remain fresh. Avoid freezing the dish because the potato mixture and mayonnaise can change texture after thawing.
Chill it for at least 30 minutes before slicing or unmolding. Use a straight-sided dish or mold and gently press each potato layer into place as you assemble it. For clean slices, use a sharp knife dipped briefly in water and wipe it clean between cuts.
Traditionally, it is served as a chilled appetizer. You can also serve a larger portion as a light lunch with a fresh salad. The crab and avocado make it satisfying, but the dish still keeps the refined, starter-like character of classic Peruvian causa.
