Ingredients

1.5 lbs beef sirloin or flank steak, thinly sliced against the grain
3 dried guajillo chiles, stemmed and seeded
2 dried ancho chiles, stemmed and seeded
1 cup pineapple juice
0.25 cup white vinegar
2 tbsp achiote paste
3 cloves garlic
1 tsp ground cumin
0.5 tsp dried oregano
0.5 tsp salt
1 tbsp olive oil
12 corn tortillas
0.5 cup finely diced fresh pineapple, for garnish
0.25 cup chopped fresh cilantro, for garnish
0.25 cup finely diced white onion, for garnish

Instructions

Place dried chiles in a bowl, cover with hot water, and let soften for 20-30 minutes. Drain, reserving a little soaking liquid.
In a blender, combine softened chiles, pineapple juice, white vinegar, achiote paste, garlic, cumin, oregano, and salt. Blend until very smooth, adding a tablespoon of chile soaking liquid if needed to reach a pourable consistency.
Place beef slices in a non-reactive dish or resealable bag. Pour the marinade over the beef, ensuring all pieces are coated. Marinate in the refrigerator for at least 2 hours, or preferably overnight.
Heat olive oil in a large skillet or cast-iron pan over medium-high heat. Remove beef from marinade, letting excess drip off. Cook beef in batches, searing quickly for 2-3 minutes per side until browned and cooked through. Do not overcrowd the pan.
Warm corn tortillas in a dry skillet or microwave until pliable.
Assemble tacos: Place cooked beef on warm tortillas, then top with diced fresh pineapple, chopped cilantro, and diced white onion. Serve immediately.

Tips

Marinating the beef overnight allows the flavors to fully penetrate, resulting in a more tender and flavorful taco filling.
Cook the beef in small batches to ensure a good sear and prevent the meat from steaming, which can make it tough.
For an authentic touch, lightly char the corn tortillas over an open flame or in a dry hot skillet until slightly browned and flexible.

Frequently Asked Questions

Can I use a different cut of beef?

Yes, thinly sliced pork shoulder or even chicken thighs can be used as alternatives, though the flavor profile will differ slightly from traditional al pastor.

What if I can't find achiote paste?

Achiote paste provides a distinct earthy flavor and red color. If unavailable, you can omit it, but the tacos will lack some of their traditional depth and hue.

How can I make these tacos spicier?

For extra heat, you can add a small amount of a spicier chile, like chile de arbol, to the marinade, or serve with a spicy salsa on the side.
