Seco de Cordero (Peruvian Lamb Stew with Coriander)
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.

Ingredients
Instructions
- Blend the coriander with the onion, garlic, aji amarillo paste and a splash of the beef stock until smooth enough to pour. Set aside.
- 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.
- 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.
- 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.
- 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.
- 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.
