Experience the ultimate Mexican street food with these tender, slow-cooked beef birria tacos. Shredded beef is tucked into corn tortillas dipped in rich chili oil, pan-fried until crispy with melted cheese, and served with a savory dipping broth.
Prepare the dried chilies by removing the stems and seeds. Roughly chop them and simmer in a saucepan of boiling water for about 10 minutes until the flesh is soft and mushy. Reserve 1/2 cup of the soaking water.
Create the adobo paste by blending the softened chilies, the reserved soaking water, garlic, small onion, tomato, dried oregano, ground cumin, and black pepper. Blitz until the mixture is as smooth as possible.
Heat 2 tablespoons of vegetable oil in a large Dutch oven or heavy-based pot over high heat. Sear the beef chunks in batches until they are aggressively browned and dark golden on all sides. Remove the beef and set aside.
In the same pot, add the adobo paste and cook for 2 minutes, stirring constantly to develop the flavors. Lower the heat if the paste begins to splatter.
Return the beef to the pot and add the beef stock, cinnamon stick, bay leaves, apple cider vinegar, and salt. Bring to a boil, then reduce the heat to a very gentle simmer. Cover with a lid and cook for 2.5 to 3 hours, or until the beef shreds easily with a fork.
Remove the beef from the pot and shred it thoroughly. Skim the red fat from the surface of the braising liquid and collect it in a small bowl; this is your 'Birria Oil'.
Take 1 cup of the remaining braising liquid (the consommé) and toss it with the shredded beef in a pan over medium heat until the liquid is absorbed. This keeps the meat incredibly moist.
To assemble, heat a non-stick skillet over medium-low heat with a teaspoon of the reserved Birria Oil. Dip a corn tortilla into the oil to coat it, then place it in the pan. Top half of the tortilla with shredded cheese, beef, chopped white onion, and cilantro.
Fold the tortilla over and pan-fry for about 2 minutes per side until the shell is crispy and the cheese has melted. Serve hot with a small bowl of the warm consommé for dipping, lime wedges, and salsa.
For the best flavor, use a combination of beef chuck and bone-in short ribs. If you prefer using a slow cooker, follow the steps to sear the beef and cook the paste, then transfer everything to the slow cooker and cook on low for 6-8 hours. Always serve the consommé warm for the best dipping experience.
