Ingredients
  

  • Beef chuck roast (3–4 pounds), trimmed and cut into large chunks
  • Avocado or olive oil (for searing)
  • Yellow onion, thinly sliced
  • Garlic (4–6 cloves), minced
  • Tomato paste (2 tablespoons)
  • Beef broth (1 cup), low-sodium
  • Apple cider vinegar (1–2 tablespoons)
  • Fresh lime juice (1 lime)
  • Chipotle peppers in adobo (1–2 peppers, minced) + 1 teaspoon adobo sauce
  • Chili powder (1 tablespoon)
  • Ground cumin (2 teaspoons)
  • Dried oregano (1 teaspoon), preferably Mexican oregano
  • Smoked paprika (1 teaspoon)
  • Ground coriander (1/2 teaspoon)
  • Sea salt and black pepper
  • Bay leaf (1)
  • Optional add-ins: sliced jalapeño, a small piece of cinnamon stick, fresh cilantro, radishes for garnish
  • For serving (keto-friendly): romaine or butter lettuce leaves, cauliflower rice, low-carb tortillas, avocado, sour cream, shredded cheese

Method
 

  1. Season the beef: Pat the chuck roast dry. Generously season all sides with salt and pepper. Let it sit while you prep the aromatics.
  2. Mix the spice paste: In a small bowl, combine chili powder, cumin, oregano, smoked paprika, coriander, minced chipotle, adobo sauce, and tomato paste. Stir in 2–3 tablespoons of broth to loosen into a thick paste.
  3. Sear for flavor: Heat a large skillet over medium-high. Add 1–2 tablespoons oil. Sear beef chunks on all sides until browned, about 2–3 minutes per side. Work in batches to avoid crowding.
  4. Layer the crockpot: Add sliced onion and garlic to the slow cooker. Place seared beef on top. Scrape any browned bits from the skillet into the pot.
  5. Add liquids and spices: Pour in the remaining beef broth, apple cider vinegar, and lime juice. Spoon the spice paste over the beef. Add the bay leaf. If you like more heat, add sliced jalapeño.
  6. Cook low and slow: Cover and cook on Low for 8–10 hours or on High for 4–5 hours, until the beef is fork-tender.
  7. Shred the beef: Remove the beef to a board and shred with two forks. Discard large pockets of fat. Remove the bay leaf from the slow cooker.
  8. Reduce the sauce (optional but recommended): If the cooking liquid is thin, ladle 1–2 cups into a saucepan and simmer 5–10 minutes to thicken. Alternatively, turn the slow cooker to High with the lid ajar for 20–30 minutes.
  9. Combine and finish: Return shredded beef to the slow cooker. Toss with the sauce until well coated. Taste and adjust with salt, pepper, a splash more lime, or a pinch of sweetener if needed to balance heat.
  10. Serve: Spoon into lettuce cups, over cauliflower rice, or in low-carb tortillas. Top with avocado, cilantro, radishes, cheese, or sour cream.
