Tacos al pastor is one of the great collision stories in food history. Lebanese immigrants brought the vertical spit-roasting technique of shawarma to Mexico. Within a generation it had been completely transformed: lamb became pork, tahini became salsa, and a slice of pineapple on top of the spit became the signature move. The result is a taco with smoky, chile-stained pork, caramelized pineapple, raw onion, cilantro, and a bit of lime. It is bright, rich, sweet, and spicy all at once, and it might be the single best taco in the Mexican canon. This sheet pan version skips the vertical spit but keeps everything that matters. One of my favorite things we make in spring and summer, and the timing is perfect heading into Cinco de Mayo.
Dried guajillo and ancho chiles, toasted and soaked, blend into a deep red marinade with achiote paste, garlic, and pineapple juice. Slicing the pork shoulder thin is critical so it can char under the broiler the way it would on a rotating spit. Two hours of marinating is the minimum, but overnight is better. Broil the pineapple slices alongside the pork until they get dark spots, then chop and mix everything together. Warm your corn tortillas on a dry comal or directly over a gas flame. Top simply: onion, cilantro, a spoonful of salsa verde, lime.
Marinate Thoroughly
Combine marinade ingredients including spices, acids, and aromatics. Mix until well blended. Add protein and turn to coat every surface completely. Cover and refrigerate for the recommended time. Proper marination allows flavors to penetrate deeply and acid to tenderize proteins. Rushing this step results in surface-level seasoning only. For Tacos al Pastor, overnight marination produces noticeably better results than short marination. The marinade components work together to transform the texture and infuse authentic flavor throughout. 
Cook at Proper Temperature
Preheat cooking surface or oven to the specified high temperature. Remove protein from marinade and arrange with space between pieces to prevent steaming. High heat caramelizes the marinade and creates charred edges typical of traditional preparation. Monitor internal temperature carefully to avoid overcooking. The goal is deeply browned, almost blackened exterior with juicy interior. Proper heat management separates excellent results from mediocre ones in this dish.
Rest and Serve Correctly
Let cooked protein rest briefly to redistribute juices before slicing. Cut against the grain for tender texture. Assemble with traditional accompaniments that balance richness and provide textural contrast. Serve immediately while still warm. The mix of spiced protein, tangy condiments, cool vegetables, and warm bread creates the complete authentic experience expected from properly prepared Mexican cuisine.

Description
Tacos al pastor trace their origins to Lebanese immigrants who brought shawarma to Mexico in the early 20th century. The vertical spit remained, but lamb was swapped for pork, and the marinade became a vivid red paste of dried chiles and achiote. A whole pineapple sits on top, its juices basting the meat as it turns. This home version uses a sheet pan to approximate the charred, caramelized edges and that essential sweet-spicy interplay that makes al pastor the king of the taqueria.
Ingredients
- 2 pounds boneless pork shoulder, sliced into 1/4-inch thick pieces
- 4 dried guajillo chiles, stemmed and seeded
- 2 dried ancho chiles, stemmed and seeded
- 1/2 cup pineapple juice
- 3 tablespoons white vinegar
- 3 cloves garlic
- 1 tablespoon achiote paste (or 1 teaspoon annatto powder)
- 1 teaspoon ground cumin
- 1/2 teaspoon dried oregano
- 1/2 teaspoon freshly ground black pepper
- 1 teaspoon kosher salt
- 4 slices fresh pineapple, about 1/2 inch thick
- Small corn tortillas, warmed
- For serving: diced white onion, fresh cilantro, lime wedges, salsa verde
Instructions
- Toast the guajillo and ancho chiles in a dry skillet over medium heat for 1-2 minutes per side until pliable and fragrant. Place in a bowl, cover with hot water, and soak for 20 minutes until soft. Drain, reserving 1/4 cup soaking liquid.
- Blend the soaked chiles, reserved liquid, pineapple juice, vinegar, garlic, achiote paste, cumin, oregano, pepper, and salt until smooth. The marinade should be a deep, brick-red paste.
- Place the sliced pork in a large bowl or zip-lock bag. Pour the marinade over and turn to coat every piece. Marinate for at least 2 hours, or overnight in the refrigerator.
- Preheat the oven to broil on high. Line a sheet pan with foil. Spread the marinated pork in a single layer on the pan, overlapping slightly. Place the pineapple slices alongside or on top.
- Broil 6 inches from the heat for 8-10 minutes until the edges of the pork are deeply charred and caramelized. Flip the meat and pineapple, then broil for another 6-8 minutes. The meat should have blackened, crispy edges.
- Chop the cooked pork into small pieces on a cutting board. Dice the broiled pineapple and mix it into the meat.
- Serve on warmed corn tortillas topped with diced white onion, cilantro, and a squeeze of lime. Pass salsa verde alongside.
Notes
- Slicing the pork thin before marinating allows the chile paste to penetrate deeply and creates more surface area for charring under the broiler.
- Achiote paste is what gives al pastor its distinctive red-orange color and earthy flavor. It can be found at Latin American grocery stores or online.
- Corn tortillas should be small (4-5 inches) and doubled up for structural integrity. Warm them on a dry comal or skillet, not in the microwave, for the best flavor and pliability.

Frequently Asked Questions
What is achiote paste and where do I find it?
Achiote paste is made from annatto seeds, garlic, vinegar, and spices. It gives al pastor its distinctive brick-red color and earthy flavor. Find it in the Latin section of most grocery stores, or online. Annatto powder works as a substitute but the flavor is less complex.
Can I make tacos al pastor without a vertical spit?
Yes. Slice the pork thin, marinate it in the chile paste, stack it on a sheet pan, and broil at high heat. The thin slices char at the edges just like they would on a trompo. Flip once and broil again.
Why toast the dried chiles before soaking?
Toasting activates the oils in the chile skins and deepens their flavor. Without toasting, the marinade tastes flat and one-dimensional. Press each chile flat in a dry skillet for 1 to 2 minutes per side until pliable and fragrant.
