Chanfainita is a Lima worker's stew of diced beef lung simmered with potato in an aji-panca-and-cumin sauce, finished with fresh mint and served over rice. The lung is pre-boiled until tender, then cut small and stewed into a dark, hearty guiso. Cheap, filling and warming, it is the archetypal menu del dia lunch sold in market stalls and corner kitchens. Often it shares the plate with mote, boiled hominy corn.
Chanfainita is rooted in the frugal criollo and Afro-Peruvian cooking of Lima, which made full use of cheap offal. Its name traces to the Spanish chanfaina, an old Iberian dish of chopped offal in sauce that crossed to the Americas and was reworked locally; the Peruvian version settled on beef lung with potato and aji panca. It is firmly working-class fare, a staple of the cheap set-menu lunch rather than restaurant cooking, and as a folk dish it has no fixed date of origin.
The lung is spongy and light, with a soft, airy chew unlike any dense muscle meat — it drinks up the dark, smoky aji panca sauce. The gravy is deep and earthy, savory with cumin, the potatoes soft and starchy; a final lift of mint cuts the richness. Hearty and a little funky, it is rib-sticking lunch food meant to be spooned over rice.
Lung is an open, air-filled spongework of tissue, so it cooks fast and stays light but can turn rubbery if overheated; it is pre-boiled until just tender, then simmered gently in sauce. Its porous structure acts like a sponge, soaking up the aji panca gravy so the flavor sits inside each piece rather than only on the surface. The potatoes release starch as they stew, thickening the sauce, while aji panca contributes smoke and color over heat.
Variations
Some cooks add a little tripe or other offal alongside the lung; others stretch it with extra potato. The aji and herb balance varies by kitchen, and a few versions lean drier while others keep it brothy. It is commonly plated with mote or rice, and sits beside sangrecita and cau cau in the canon of Lima's frugal offal lunches.

How it's made
8 steps · 30 min active + 45 min waiting
- 145 min
Rinse the beef lung and boil it with aromatics until tender, skimming the foam.
Watch outBoil the lung only until just tender, skimming the foam — its spongy tissue cooks fast and turns rubbery if overheated, so stop the moment it yields.
- 28 min
Drain, cool and dice the cooked lung into small cubes.
- 38 min
Saute red onion, garlic and aji panca paste in oil until deeply fragrant.
- 44 min
Add cumin, oregano and a little of the cooking broth to build the sauce.
- 518 min
Add diced potato and the lung and simmer together until the potato is soft.
Watch outSimmer the diced lung with the potato until the potato softens — the porous lung is soaking up the aji panca gravy now, so let it sit in the sauce to take on flavour throughout.
- 64 min
Adjust the sauce so it thickens and coats; season with salt and pepper.
- 71 min
Stir in chopped fresh mint at the end.
- 81 min
