Instructions
Prepare the Peppers: In a dry skillet set over medium heat, toast the guajillo and ancho peppers for approximately 2-3 minutes, stirring frequently, until they become fragrant. Ensure they do not burn to maintain a pleasant flavor. Remove from heat and transfer to the slow cooker.
Blend the Marinade: In your blender, combine the toasted peppers, minced garlic, quartered onion, ground cumin, dried oregano, smoked paprika, ground cinnamon, beef broth, apple cider vinegar, and a generous pinch of salt and pepper. Blend the mixture until smooth and well-combined, ensuring no large chunks remain.
Combine in Slow Cooker: Place the chopped beef chuck roast into the slow cooker, spreading it out evenly. Pour the blended marinade over the meat, ensuring that every piece is generously coated.
Cook: Cover the slow cooker with its lid and set it to the low setting for 8-10 hours or high for 4-5 hours, until the meat is tender enough to shred easily with a fork.
Shred the Meat: Once the cooking time is completed, carefully remove the beef from the slow cooker. Using two forks, shred the meat into bite-sized pieces. Reserve the flavorful broth in the slow cooker for serving.
Warm the Tortillas: In a skillet, warm the corn tortillas on medium heat for about 30 seconds on each side, or until they are warmed through and pliable. This step is essential for easy assembly and optimal enjoyment of the tacos.
Assemble the Tacos: Take a warm tortilla and generously fill it with the shredded beef. To enhance the flavor, drizzle some of the reserved cooking broth over the meat.
Garnish and Serve: Top each taco with freshly chopped cilantro and diced onion. Add a squeeze of lime for brightness and flavor. Serve the tacos alongside a small bowl of the reserved broth for dipping.
