Chairo is a hearty, thick soup from Peru’s southern highlands, made with black chuño, lamb, dried lamb, potatoes, fava beans, and grains. Its rich flavor comes from slow cooking and from the combination of preserved Andean ingredients with fresh vegetables.
In areas such as Puno, Cusco, Arequipa, and Andahuaylas, chairo is a meaningful part of local food traditions. It is usually served piping hot in generous portions, often as a full meal that restores energy after a long day. Black chuño, an ancestral freeze-dried potato, is one of its defining ingredients and gives the soup its unmistakable texture.

Ingredients
- 300 g lamb pieces with bone (about 10.5 oz)
- 120 g dried lamb, chopped (about 4 oz)
- 150 g black chuño (about 10 medium pieces)
- 150 g pearled wheat (¾ cup)
- 200 g white potatoes (2 medium potatoes)
- 180 g fresh shelled fava beans (1½ cups)
- 150 g grated macre squash or kabocha squash (1 cup)
- 100 g carrot, cut into thin batons (1 medium carrot)
- 80 g chopped leek, white part only (½ cup)
- 100 g chopped red onion (1 medium onion)
- 20 g garlic paste (4 garlic cloves)
- 30 ml vegetable oil (2 tablespoons)
- 1.8 liters water (7½ cups)
- 5 g dried oregano (1 teaspoon)
- 1 g ground cumin (¼ teaspoon)
- 15 g fresh mint (6 sprigs)
- 10 g chopped parsley (¼ cup)
- 8 g salt (1½ teaspoons)
- 2 g ground black pepper (¼ teaspoon)
Preparation
- Soak the chuño and wheat, rinse the chuño several times under cold water and soak it overnight in plenty of water. Soak the wheat separately so it cooks evenly the next day.
- Cook the meats, place the lamb and dried lamb in a large pot with 1.8 liters of water. Bring to a boil, skim off any foam from the surface, and cook over medium heat for 45 minutes, until the lamb begins to soften.
- Make the seasoning base, heat the oil in a skillet and cook the onion, garlic, oregano, cumin, black pepper, and salt for 6 to 8 minutes. Add the grated squash and cook until it softens and creates a thick, fragrant base.
- Add the wheat and chuño, stir the drained wheat and soaked chuño into the pot with the meats. Cook over medium heat for 25 minutes, stirring occasionally so the chuño does not stick to the bottom.
- Finish the soup, add the seasoning base, carrot, leek, fava beans, and potatoes cut into medium cubes. Cook for another 20 to 25 minutes, until the potatoes are tender, the wheat is soft, and the broth has a lightly thickened consistency.
- Add the herbs and serve, stir in the mint and parsley during the last 3 minutes of cooking. Taste for salt, let the soup rest for 5 minutes, and serve it very hot, making sure each bowl includes lamb, chuño, potatoes, and fava beans.
Chef’s tips
- Rinse black chuño thoroughly before soaking it to reduce its strong earthy flavor.
- Use bone-in lamb because it gives the broth more depth and body.
- Do not overcook the fava beans; they should be tender but still hold their shape.
- Add hot water if the soup becomes too thick while cooking.
- Taste before adding extra salt because dried lamb is naturally concentrated and salty.
Traditional variations
In Puno, chairo is often made with charqui, hominy corn, and fava beans. Some Cusco-style versions include lamb offal, wheat, and a stronger herbal profile. In Arequipa, recipes may include beef, black chuño, squash, and corn, depending on local ingredients and family tradition.
How to serve
Serve chairo in deep bowls while it is still steaming hot, with a generous portion of meat in every serving. In the southern Peruvian highlands, it is commonly enjoyed as a main dish with ground chili sauce or llajua on the side.
Serve it with toasted Andean corn, toasted fava beans, or a small portion of cooked hominy. Muña tea or chicha de jora are traditional-style drinks that pair well with its savory flavor.

A little history
Chairo is closely connected to highland cooking and to preserved foods such as chuño and dried lamb. These ingredients could be stored for long periods, making them especially valuable during cold seasons, demanding agricultural work, and travel through rural Andean areas.
The name is associated with Andean terms such as “chayru,” referring to a soup or food prepared with chuño. While related versions exist in several Andean regions, chairo holds a strong place in the food culture of southern Peru.
Frequently Asked Questions
Black chuño is a traditional Andean freeze-dried potato. Potatoes are exposed to freezing nighttime temperatures, dried, and washed until they can be stored for long periods. In chairo, it creates a distinctive soft texture and helps thicken the broth. Rinse and soak it well before cooking for the best flavor.
Yes. You can make chairo using only bone-in lamb, although dried lamb gives the soup its deeper, more concentrated flavor. If you cannot find it, use a little more lamb with bone and simmer the broth slowly to build richness before adding the vegetables and grains.
Store cooled chairo in an airtight container in the refrigerator for 2 to 3 days. The chuño and wheat will absorb broth as the soup rests, so add a little hot water when reheating. Warm it over medium heat until it reaches a gentle boil before serving.
Chairo should be hearty and slightly thick, but it should still have enough broth to eat as a soup. Grated squash, chuño, and wheat naturally give it body. Simmer uncovered if it looks too thin, or add hot water gradually if it becomes too dense.
