Creating your Crock Pot Birria Tacos can be straightforward if you follow these simple steps:

1. Prepare the Dried Chiles: Soak the guajillo and ancho chiles in hot water for about 15 minutes until they are soft.
2. Make the Sauce: In a blender, combine the softened chiles, beef broth, apple cider vinegar, chopped onion, garlic, cumin, oregano, paprika, cinnamon, salt, and pepper. Blend until smooth.
3. Prepare the Meat: Cut the beef chuck roast into large chunks and place it in the Crock Pot.
4. Add the Sauce: Pour the blended sauce over the meat in the Crock Pot.
5. Slow-Cook: Cover and cook on low for 8 hours or high for 4 hours until the beef is very tender and easily shreds.
6. Shred the Meat: Use two forks to shred the meat directly in the Crock Pot. Mix it with the cooking liquid for extra flavor.
7. Heat the Tortillas: On a skillet over medium heat, warm corn or flour tortillas until pliable.
8. Assemble the Tacos: Place a generous portion of shredded beef on a warm tortilla. Top with chopped onions, cilantro, and any other desired toppings.
9. Serve: Serve with lime wedges on the side for squeezing over your tacos.
