Slow Cooker Tacos al Pastor

Slow cooker tacos al pastor combine the traditional flavors of cumin, coriander, pineapple, citrus, and adobo. The modern part? Your slow cooker.

Three assembled slow cooker tacos al pastor with shredded pork, pineapple-avocado salsa, and chipotle mayo, with lime wedges on the side.

Tacos al pastor is hands down my favorite taco. I was first introduced to it at our neighborhood taco joint when we lived in Chicago, and I quickly fell in love. Tacos al pastor contain slowly roasted and super-flavorful pork paired with juicy, sweet pineapple. To re-create this taco for a delicious, healthy weeknight dinner, I use a pork shoulder roast and trim most of the fat to make it much leaner. It’s still scrumptious and juicy, thanks to a delicious marinade and a slow cooker. Roasting the onions and pineapple is the secret to bringing out their natural sweetness and imparting a smoky flavor to the marinade. The marinade also includes bold flavors like adobo, cumin, garlic and bright notes of citrus. This taco is just as good, if not better, than the one I fell in love with in Chicago!–Danielle Davis

How much pork butt can I cook for tacos al pastor?

If you feel the need to double this recipe (and look, we don’t blame you), remember that size matters. Although exactly how it matters depends on your personal preference. We prefer to roast a couple modestly sized 3- or 4-pound pork butts side by side in the same roasting pan rather than a single 8-pound pork butt, only because they seem to remain moister. But that’s just us.

Make the tacos

Preheat the oven to 400°F (204°C). Slick a rimmed baking sheet with cooking spray.

Season the pork with 3 teaspoons of the salt and the black pepper, making sure to cover the whole pork shoulder.

Place the onion and pineapple on the prepared baking sheet. Drizzle the onion and pineapple with 1 tablespoon of the oil and sprinkle them with 1/4 teaspoon of the salt.

Roast the onion and pineapple until tender, flipping them halfway through the cooking time, 15 to 16 minutes. Add the brown sugar and toss the roasted onion and pineapple to coat them. Roast the onion and pineapple until they start to caramelize, 3 to 4 minutes.

Drop the onion and pineapple into a blender or large food processor. Add the lime juice, lime zest, orange juice, orange zest, remaining 1 tablespoon of oil, broth, vinegar, garlic, chipotle peppers, adobo sauce, chili powder, cumin, coriander, oregano, onion powder, allspice, and remaining 1/4 teaspoon of salt. Blitz the ingredients until a smooth, thick sauce forms.

Place the pork in the slow cooker and cover with the pineapple sauce. Cook on low heat until the pork is fork tender, 7 to 8 hours.

Move the pork to a large bowl, and remove the bone if you are cooking a bone-in pork shoulder. Remove any fatty pieces, then use forks or tongs to shred the pork.

Stir in 1/2 cup or more of the leftover sauce from the slow cooker, if desired.

Make the pineapple-avocado salsa

In a medium bowl, combine the onion, pineapple and avocado. Stir in the oil, lime juice, agave, cilantro, and salt, and mix until all of the ingredients are well combined.

Make the chipotle mayo

In a small bowl, combine the mayo, yogurt, adobo sauce, and lime juice and stir well.

Over a gas burner or in a medium skillet over medium-high heat, slightly char the corn tortillas. Top each tortilla with the pork, pineapple-avocado salsa, and chipotle mayo.

Recipe Testers' Reviews

This recipe for slow cooker tacos al pastor requires some patience and planning but the rewards are great and therefore worth it. The marinade is the most time-consuming part to make and then it's smooth sailing. The slow cooker was a clever way to achieve the spit grilled effect and your house will smell pretty amazing even a day later! You get the scents of everything from the adobo and the pineapple and all the rich flavors of the marinade come through in the shredded pork.

The pineapple and avocado salsa is also amazing and I would eat this alone or with fish or shrimp. I also liked the idea of doing half yogurt half mayo for the sauce (I used Duke's mayonnaise.) I had a fair amount of fat on my pork shoulder, so I only got enough for about 10 tacos.

These slow cooker tacos al pastor were amazingly delicious! There was lots of prep involved but well worth it in the end. I'm not a big fan of pork tacos, they always seem to be heavy and rich so I eat two tacos and then I'm done. Not tonight! The pineapple and the orange really came through in the pork itself so it wasn't heavy and rich, it was fresh and delicious. The chipotle mayo and the salsa were the perfect companions (nice change from slaw). This dish would be a perfect summer dish to take to a pot-luck or when you have friends over sitting in the backyard having a cold beer.
