Start by soaking dried chilies in hot water until soft and pliable. Then blend them with onions, garlic, tomatoes, and spices. This creates a rich, smoky base that defines quesabirria flavor.
Place beef in a pot and pour the blended chili sauce over it. Add broth, bay leaves, and seasonings, then slow simmer gently. Cook until meat becomes tender enough to shred easily.
Remove beef from the pot once fully cooked and tender. Use forks to shred it into juicy, bite-sized strands. Keep it moist by mixing it with a bit of consommé.
Dip corn tortillas into the top layer of red consommé fat. This gives them color and helps them crisp while frying. Heat them lightly before assembling tacos.
Add shredded beef and cheese onto one side of tortilla. Fold and cook on a hot skillet until crispy and golden. The cheese should melt perfectly inside.
Serve tacos hot with a small bowl of consommé for dipping. This dipping broth is what makes quesabirria so special. Enjoy immediately for best texture and flavor.
