Seco de Cordero (Peruvian Lamb Stew with Coriander)

In Peru, seco de cordero is the kind of slow-simmered lamb stew made for serving with plain rice and plenty of sauce. The dish is defined by its vivid coriander base, blended here with onion, garlic and aji amarillo paste, then cooked down so the raw herb flavour becomes rounded and savoury. Lamb shoulder gives the stew body as it braises, turning tender in a glossy gravy enriched with cumin and stock. Peas bring a little sweetness at the end, while lime sharpens the finish. It is hearty, aromatic and practical: a one-pot main that rewards patient cooking and needs little more than long-grain rice to make it complete.

Why this recipe works

  • Deep savoury base: Browning the lamb first adds caramelised depth that enriches the coriander and aji amarillo sauce as it simmers.
  • Recognisable seco character: Blending fresh coriander with onion, garlic and chilli paste creates the vivid, herb-led sauce that defines the dish.
  • Bright finish: A squeeze of lime at the end cuts through the richness of the lamb and sharpens the flavour of the sauce.

Ingredient notes

  • Aji amarillo paste: Aji amarillo gives the stew its fruity, rounded heat rather than sharp chilli burn.
  • Use fresh coriander: Fresh coriander leaves and tender stems are essential for the sauce; dried coriander will not give the same colour or flavour.
  • Blend until pourable: The coriander mixture does not need to be perfectly silky, but it should be smooth enough to coat the lamb evenly.

Adjust the heat

  • For less heat: Use a little less aji amarillo paste, then adjust at the end if the sauce needs more warmth.
  • For more heat: Increase the aji amarillo paste slightly or serve extra on the side so each portion can be adjusted.
  • Keep it balanced: The rice and lime help balance the chilli, so avoid making the sauce too hot before the stew has finished simmering.

Timing notes

  • Mostly hands-off cooking: The active work is browning the lamb and blending the sauce; the tenderness comes from the longer covered simmer.
  • Cook to tenderness: Use the timing as a guide and continue simmering gently until the lamb is very tender and the sauce looks glossy.
  • Good the next day: Like many braised stews, the flavour settles well after chilling, making it a strong make-ahead option.

Make-ahead tips

  • Freeze the stew, not the rice: For the best texture, freeze the lamb and sauce separately and cook fresh rice when serving.
  • Reheat gently: Warm on the hob with a splash of water or stock, stirring occasionally, until piping hot throughout.
  • Keep rice separate: Storing the rice apart from the stew prevents it from absorbing too much sauce and turning soft.

  1. Blend the coriander with the onion, garlic, aji amarillo paste and a splash of the beef stock until smooth enough to pour. Set aside.
  2. Cut the lamb into large bite-sized pieces. Heat the vegetable oil in a dutch oven over medium-high heat, then brown the lamb well in batches so it takes on colour.
  3. Stir in the ground cumin and cook for 30 seconds until fragrant. Pour in the blended coriander mixture and cook for 3 to 4 minutes, stirring, until it darkens slightly and smells cooked rather than raw.
  4. Add the remaining beef stock and bring to a gentle simmer. Cover and cook on low for 70 to 80 minutes, stirring occasionally, until the lamb is very tender and the sauce is glossy.
  5. Rinse the rice until the water runs mostly clear, then cook it in a saucepan with water according to the packet instructions. Keep it covered off the heat for 5 minutes, then fluff with a fork.
  6. Stir the peas into the stew and simmer uncovered for 5 to 7 minutes until hot and tender. Squeeze in lime juice to taste, then serve the stew with the rice so it can soak up the sauce.

Recipe notes

Tips

  • For the best flavour, take time to brown the lamb properly; the caramelised bits on the base of the pan will enrich the sauce once the stock is added.
  • If the sauce looks thin at the end, simmer uncovered for a few minutes to reduce; if it looks too thick, loosen with a splash of beef stock.
  • If serving vulnerable groups, ensure the stew is simmered until the lamb is piping hot throughout before serving.

Substitutions

  • Replace beef stock with chicken stock for a lighter, cleaner-tasting sauce.
  • Replace lime with lemon for a similar bright finish.

Storage

  • Refrigerate up to 3 days
  • Cool the stew quickly, then refrigerate in a sealed container. Reheat gently on the hob with a splash of water or beef stock until piping hot; freeze the stew (without rice) for best texture.
