How long does the beef need to braise?
Typically 3–4 hours on low heat or until the beef shreds easily with a fork. Time varies based on oven temperature and exact cut size.
Can I make this in a slow cooker or Instant Pot?
Yes. Slow cooker: 6–8 hours on low. Instant Pot: 60–90 minutes high pressure, then 10-minute natural release.
What are the best dried chiles to use?
Ancho and guajillo are mild and fruity; this recipe uses a mix. Avoid very hot varieties unless you prefer spicy tacos.
Can I prepare this ahead?
Yes. Braise the beef fully, cool, and refrigerate up to 3 days. Reheat gently on stovetop with a splash of broth.
What if my beef isn't tender after 3 hours?
Continue braising in 30-minute increments. Older or tougher cuts may need the full 4+ hours. Resist the urge to raise heat, which toughens meat.
