Early morning barbacoa tacos with fresh cilantro and onion are a cherished weekend ritual. This high protein, family-friendly dish is a fresh, rich, carnivore breakfast tradition.
Trim excess fat from the beef chuck roast and cut it into large chunks for even cooking.
Place beef in a slow cooker or dutch oven, add garlic cloves, bay leaves, cumin, pepper, salt, and oregano. Cover with water until beef is just submerged.
Cook on low heat for 6 hours (or simmer gently if using stovetop), ensuring the liquid never boils vigorously—this preserves tenderness.
Remove beef and shred with two forks, mixing in a few tablespoons of the cooking liquid for moist texture.
Warm corn tortillas in a dry skillet over medium heat for 30 seconds per side. Assemble tacos with shredded beef, diced onion, chopped cilantro, and a squeeze of lime.
