This is one of the few dishes my grandmother Ismelda loved both to cook and to eat. As she got older, many of the things she loved were no longer options for her. The food changed, the portions changed, and that took a real toll on her mood. But whenever someone mentioned Caigua Rellena, something shifted. I could literally see her light up. It was her dish, and that alone is reason enough to share it.
The recipe I am making here is the one she used to prepare for us when I was a kid. I have only made a few minor adjustments to make it work for those of us cooking outside of Peru who do not always have the exact same fresh ingredients on hand.
Caigua (scientific name Cyclanthera pedata) is a climbing plant whose fruit is used as a staple vegetable in Peruvian cuisine and across other regions in Latin America. Depending on the exact region, it is also known as caihua, achocha, or jaiva.
It has an elongated shape and pale green skin. Inside, it is completely hollow, containing a cluster of seeds that must be removed before stuffing. Its natural flavor is very mild and neutral, closely resembling a cucumber or chayote squash. The most interesting thing about caigua is what happens when you cook it: it becomes incredibly tender, completely absorbs the flavors of the filling and the broth, and changes color to a much darker, vibrant olive green. While it is sometimes used in juices for its antioxidant properties in Peru, stuffing it is by far its most classic culinary application.
Finding fresh caigua is very difficult outside of Peru and other Andean countries. In the United States, your best option is to look for it frozen in specialized Latin or Peruvian markets. Some Ecuadorian grocery stores also carry it regularly.
The frozen version works perfectly for this recipe. The only major difference is that frozen caigua does not need to be blanched in boiling water before stuffing, as the freezing and thawing process has already softened the cell walls. If you try to blanch thawed frozen caigua, it will fall apart in the pan.
The filling requires aji panca paste for its signature flavor. If your local Latin market does not stock it, you can easily order Aji Panca Paste on Amazon to keep in your pantry.
Choose caiguas of the same size
If all of your caiguas are roughly the same size, they will cook evenly in the pan. Mixing massive caiguas with small ones means some will turn out perfectly tender while others end up either mushy and overcooked or too crunchy.
Do not overstuff them
It is incredibly tempting to pack every single centimeter of space inside the vegetable, but an overstuffed caigua will burst open either during the simmering process or the moment you try to plate it. Pack the filling in firmly, but leave a small margin at the top before placing the “lid” back on.
Reserve part of the filling for the cooking broth
This is the specific technique that makes all the difference. Before stuffing the caiguas, set aside about 6 tablespoons of the meat filling and mix it directly into the beef broth in the pan. This creates a deeply flavored, rich sauce that the caiguas simmer in, which is exactly what you spoon over the rice at the end.
Blanch only if the caigua is fresh
A quick one-minute dip in boiling water is all a fresh caigua needs to soften up just enough to make stuffing easy. If you are using frozen caigua, skip this step entirely.
Give the sofrito time
The red onion, garlic, tomato paste, and aji pastes need to cook over medium heat for at least 5 minutes. This allows the ingredients to integrate properly, caramelize, and lose their raw, sharp flavors. Do not rush this step.
Ingredients are very basic, and the star of the dish is the Caigua, if you are wondering how it tastes, it has a unique flavor, and it is tender and juicy; a must-try.
As with most things in Peruvian cuisine, it all starts with an “aderezo”, sautee, onions, garlic, and some Ají Panca paste, to add color and flavor.
If you wondering if you have seen this filling in another Peruvian dish, you might be right, the filling is really similar to the one we use in our recipe for Papa Rellena,
White rice is the mandatory classic side. The caigua is served directly on top of the rice, and you must spoon the rich, beefy sauce from the bottom of the pan generously over the top. The rice acts as a sponge, soaking up that sauce and becoming an essential part of the dish.
If you want to add some brightness to the plate, a fresh Salsa Criolla served on the side provides a sharp, acidic crunch that perfectly cuts through the richness of the beef filling.
Store the leftover stuffed caiguas and any remaining sauce in an airtight container in the refrigerator for up to 3 days.
When reheating, do it gently in a skillet over low heat, adding a small splash of beef broth or water so the meat does not dry out. While the microwave works in a pinch, the caigua tends to lose some of its texture and become slightly rubbery. I do not recommend freezing this dish.
What does caigua taste like?
On its own, it has a very mild, neutral flavor similar to a cucumber or chayote. Because it has no strong flavor of its own, it is the perfect vessel for stuffing, as it completely absorbs the rich flavors of the beef and the broth it cooks in.
Can I use a filling other than beef?
Yes. While ground beef is the classic choice, many households in Peru stuff them with ground chicken, but you can try other fillings like shredded tuna or even a vegetarian quinoa and cheese mixture.
Why does the caigua change color when cooked?
As the heat breaks down the vegetable, it absorbs the deeply colored aji panca and beef broth, changing its appearance from a pale, light green to a dark, saturated olive color.
Can I prepare the filling ahead of time?
Absolutely. You can make the beef filling a day in advance and store it in the fridge. Like many stews and meat fillings, the flavors actually deepen and improve after sitting overnight.
Is the filling similar to Papa Rellena?
Yes, it shares the exact same culinary DNA. The combination of ground beef, onions, aji panca, raisins, hard-boiled eggs, and black olives is a classic Peruvian “picadillo” used to stuff everything from potatoes (Papa Rellena) to rocoto peppers (Rocoto Relleno).
