Three plated al pastor tacos with decorative additions


  • 2.5 pounds boneless American lamb shoulder
  • 3 garlic cloves, (chopped)
  • 2 tablespoon salt-free chili powder
  • 2 teaspoon ground paprika
  • 2 chipotle peppers adobo, (use less for a milder version)
  • 1 cup fresh pineapple chunks
  • 1/2 cup pineapple juice
  • 1/4 cup white vinegar
  • Kosher salt, (to taste)
  • Freshly ground pepper,(to taste)
  • Flour tortillas
  • Fresh cilantro leaves, pico de gallo, sour cream, avocado, (for garnish)
  • Cotija cheese crumbled, (for garnish)


Before you begin prepping your Al Pastor Sauce, set the boneless lamb shoulder on a baking sheet to bring to room temperature.

Next, in a food processor combine garlic, chili powder, paprika, chipotle peppers, pineapple chunks, pineapple juice, vinegar, kosher salt, and pepper. Blend until smooth.

Place the lamb shoulder into the bottom of a 5-quart slow cooker. Cover the lamb shoulder with the “Al pastor sauce”. Set the slow cooker either on low for 8-hours or on high for 4-hours.

* Note: The USDA recommends that lamb reach an internal temperature of at least 145 degrees F with a 3-minute rest.

Once cooked, remove the lamb shoulder from the slow cooker and place on the cutting board. Using two forks shred the lamb.

Toast a tortilla and then top with shredded lamb and desired toppings.

  1. I used a full 15 oz can of pineapple chunks and cooked it with a lamb neck. The sauce is delish! This would work well on any tough cuts, such as lamb riblets, bone-in shoulder, shanks, etc… and you can pull out the bones before shredding the meat. Yummmmmmm
