Pit-Style Lamb Barbacoa (Barbacoa de Borrego)
Lamb rubbed in a deep red chile adobo and steamed for hours wrapped in maguey leaves until it falls apart at the touch of a spoon, served with its own rich consomé. This is the slow, Sunday-market treat of central Mexico, made foolproof for a home oven.

Steps
Make the chile adobo
Toast the guajillo and ancho chiles on a dry hot skillet for about 20 seconds per side, just until fragrant and pliable, not burnt (burnt chile turns bitter). Soak them in hot water for 15 minutes until soft, then drain. Blend the chiles with the garlic, cumin, marjoram, thyme, one bay leaf, vinegar, salt and a splash of water into a smooth, thick paste.
- 4 guajillo chiles
- 2 ancho chiles
- 6 cloves garlic
- 1 tsp cumin seeds
- 1 tsp marjoram
- 1 tsp thyme
- 1 bay leaf
- 60 ml white vinegar
- 1 tbsp salt
✅ Done when: the adobo is smooth, deep red and thick enough to coat a spoon
Marinate the lamb
With a sharp knife, make a few shallow cuts into each piece of lamb so the adobo can soak in. Rub the paste all over every piece, pushing it into the cuts. Cover and refrigerate for at least 8 hours, or up to 24, so the chile and herbs really get into the meat.
- 2 kg lamb pieces
✅ Done when: the lamb looks deep red all over and smells strongly of chile and herbs, not raw
Set up the pot
In a large heavy pot or Dutch oven, place the soaked chickpeas (or rice), the remaining bay leaf, the halved onion and the water or broth. This liquid sits below the lamb and slowly becomes the , catching every drop of juice that drips down. Set a steamer rack or metal colander inside the pot, above the liquid without touching it, and line it with the maguey or banana leaves, overlapping them and leaving plenty of overhang to fold over later.
- 200 g chickpeas or rice
- 1 bay leaf
- 1 onion, halved
- 2 litres water or broth
- 6–8 large maguey or banana leaves
Wrap and Steam Slowly
Lay the marinated lamb and the avocado leaves on top of the lined rack, then fold the leaves over tightly to seal the meat completely, like wrapping a big tamal. The tight wrap traps the steam and juices around the meat instead of letting them escape, which is what makes the lamb so moist. Cover the pot with its lid, sealing the edges with a layer of foil underneath if needed, and cook in an oven preheated to 150°C (300°F) for 4½ to 5 hours.
- 2 kg marinated lamb
- 4 avocado leaves
- 6–8 large leaves (to fold over)
✅ Done when: the meat pulls apart easily with a fork and almost falls off the bone on its own
Rest, then shred
Take the pot out of the oven and let it rest unopened for 15 minutes so the juices settle back into the meat. Open the leaf wrap carefully, standing back as the trapped steam escapes, then shred the lamb with two forks, discarding the bones and leaves.
✅ Done when: the lamb shreds into tender strands with almost no resistance
Finish the consomé and serve
Strain the cooking liquid from the bottom of the pot, keeping the chickpeas or rice and discarding the onion and bay leaf. Skim off excess fat, taste and adjust the salt, then stir in the chopped cilantro. Serve the shredded lamb hot with bowls of the , warm tortillas, chopped onion, more cilantro, lime wedges and your favourite salsa.

The Story Behind the Dish
Barbacoa began as a way of cooking meat slowly in a pit lined with hot stones and maguey leaves, a technique rooted in central Mexico long before lamb arrived with the Spanish. Once sheep became common in the highlands of Hidalgo and the Valley of Mexico, lamb became the meat of choice, taking on the chile adobo and herbs that define the dish today.
Traditionally it is still cooked overnight in an earthen pit, the meat wrapped in maguey leaves above a pot that fills with consomé as it steams. Families gather around it on Sunday mornings, buying it fresh from market stalls to eat with tortillas, salsa and the broth itself as a starter.
⭐ Why It's Famous
The combination of smoky maguey leaf, rich chile adobo and hours of slow steaming gives barbacoa a depth and tenderness that no quick-cooked lamb dish can match, and the consomé that comes with it is considered just as much a treasure as the meat.
💡 Fun Fact
Many barbacoa cooks still swear that the dish only tastes right when cooked in an underground pit; the maguey leaves themselves add a faint, grassy sweetness that no other wrapping quite reproduces.
