Barbacoa (Slow-Cooked Beef in Chilli and Vinegar Sauce)
Why this recipe works
- Layered chilli depth: Guajillo and ancho chilli powders bring earthy, rounded heat, while cumin, oregano, clove and bay add savoury complexity.
- Slow-braised tenderness: A long, gentle cook breaks down beef chuck into shreddable meat without drying it out.
- Rich but balanced: Apple cider vinegar cuts through the beef’s richness and keeps the sauce bright rather than heavy.
- Improves with resting: Cooling the beef in its sauce helps the flavours settle and makes reheating straightforward.
Get the most out of this recipe
Adjust the heat
- For a gentler heat: Use more ancho-style chilli powder in place of some guajillo for a softer, smokier warmth.
- For extra heat: Add a small amount of hotter chilli powder or chipotle chilli powder to the sauce, tasting as you go.
- Keep the tang in check: If increasing the chilli, keep enough vinegar in the sauce to stop the beef tasting flat or overly rich.
Timing notes
- Mostly hands-off cooking: The active work is mainly seasoning, mixing the sauce and shredding; the tenderness comes from the slow braise.
- Reduce the sauce at the end: Do not skip the uncovered simmer after shredding; it concentrates the cooking liquid so it clings to the beef.
- Excellent the next day: The flavour deepens after resting in the sauce, making this a strong make-ahead option.
Common mistakes
- Boiling too hard: Keep the liquid at a bare simmer; vigorous boiling can toughen the meat and reduce the sauce too quickly.
- Letting the pot run dry: The beef should stay partly surrounded by liquid during the braise. Add a little more stock if the sauce reduces too far.
- Returning beef to thin sauce: Reduce the cooking liquid until glossy before mixing it back through the shredded meat.
Make-ahead tips
- Cook ahead: Prepare the barbacoa in advance and chill it in the sauce so the beef stays moist.
- Reheat gently: Warm over low heat with a splash of stock if needed, stirring until the beef is piping hot.
- Freeze in portions: Freeze cooled barbacoa with some sauce in each portion, then defrost overnight in the fridge before reheating.

Ingredients
Instructions
- Pat the beef dry and season all over with 1 tsp of the fine sea salt. Peel and finely chop the yellow onion, then peel the garlic cloves and crush them.
- In a small bowl, whisk together the guajillo chili powder, ancho chili powder, ground cumin, dried oregano, ground cloves, apple cider vinegar, beef stock, and the remaining 1 tsp fine sea salt. Set the sauce aside while you start the braise.
- Put the onion and garlic in the base of a dutch oven and sit the beef on top. Pour over the chilli-vinegar sauce and tuck in the bay leaves.
- Bring to a gentle simmer over medium heat, then cover with a tight-fitting lid and turn the heat to low. Cook very gently for 3 hours, turning the beef once or twice, until it is fork-tender and shreds easily.
- Transfer the beef to a board and shred it with two forks, discarding any large pieces of fat. Keep the cooking liquid in the pot.
- Simmer the cooking liquid uncovered over medium heat for 10 to 15 minutes until slightly reduced and glossy, then return the shredded beef to the pot. Stir well so the meat is thoroughly coated, and cook for 2 to 3 minutes to warm through.
Recipe notes
Tips
- Keep the heat low enough that the liquid barely bubbles; a gentle braise gives the most tender, shreddable beef.
- If the sauce reduces too quickly during cooking, add a splash of beef stock to keep the beef partially submerged.
- For best results, cool the barbacoa in its sauce, then reheat gently; the flavour deepens as it rests.
Substitutions
- Replace apple cider vinegar with white wine vinegar for a slightly sharper tang.
- Replace beef stock with chicken stock for a lighter, less beefy sauce.
- Replace guajillo chili powder with extra ancho chili powder for a milder, smokier heat.
Storage
- Refrigerate up to 4 days
- Cool completely, then refrigerate in a sealed container with the sauce. Reheat gently on the hob over low heat with a splash of beef stock until piping hot. Freeze in portions for up to 3 months and defrost overnight in the fridge before reheating.
