Instructions

1. 1

   Soften the chillies

   Bring 750 ml (3 cups) of water to the boil. Add the ancho and guajillo chillies, then lower the heat and simmer for 10 minutes, until softened and rehydrated. Lift the chillies out of the water and set them aside.

2. 2

   Blend the marinade

   Put the softened chillies, 150 g (1 cup) of the diced pineapple, chipotles in adobo, garlic, onion, orange juice and pineapple juice in a food processor or blender. Blend until smooth. Add the oregano, cumin, smoked paprika, salt and pepper, then pulse a few times to combine. Taste and adjust the seasoning if needed.

3. 3

   Prepare the pork

   Prick the pork all over with a fork so the marinade can work into the meat.

4. 4

   Slow-cook and shred

   Put the pork, marinade and remaining 300 g (2 cups) of diced pineapple in a large slow cooker and mix to coat. Cook on HIGH for 4 hours or LOW for 8 hours. Twenty minutes before the cooking time ends, transfer the meat to a large plate and shred it with a fork. Return it to the slow cooker and cook for the remaining 20 minutes.

5. 5

   Assemble the tacos

   Serve the pork in warmed tortillas with coriander, diced onion and diced pineapple on top. Serve with lime wedges.

What are tacos al pastor?

Tacos al pastor are associated with central Mexico and draw on spit-roasted methods brought by Lebanese immigrants, adapted with Mexican chillies and seasonings. The traditional cooking method uses thinly sliced pork cooked on a vertical spit.

This version uses a slow cooker rather than a spit, with dried chillies, chipotle, citrus and pineapple blended into a marinade. The long, gentle cooking makes the pork easy to shred, while fresh toppings bring contrast at the table.

Nutrition and macros by portion

The nutrition label shows one serving as written: 650 calories, 40g protein, 30g carbs, 43g fat.

Most of the energy and fat come from the pork shoulder, which also supplies most of the protein; tortillas contribute much of the carbohydrate. Pineapple and the juices add some carbohydrate, while the salt and chipotles contribute to the sodium. Serve with extra fresh vegetables or a crisp salad to add freshness alongside the tacos.

A marinade with depth

Dried chillies: rehydrating the ancho and guajillos softens them for blending and brings their flavour into the marinade. Chipotles in adobo add a smoky, spicy note, so take care to include the sauce as well as the peppers.

Fruit and spice: orange juice and pineapple juice loosen the mixture, while oregano, cumin and smoked paprika give it savoury warmth. Blending until smooth helps the marinade coat the pork evenly.

Why the pork needs time

Pork shoulder has enough connective tissue and fat to become tender during a long, moist cook. Trimming excess fat keeps the cooking liquid from becoming overly greasy, but leave some marbling in place.

A fork-prick over the surface gives the marinade more places to cling. The pork is ready to shred when it yields easily to a fork; if it still feels firm, it needs more cooking time.

Shred before the finish

Shredding the pork for the final 20 minutes lets the strands take up more of the cooking juices. Return the meat to the cooker promptly so it stays moist as it finishes.

The slow-cooker setting changes the overall timing: allow 4 hours on HIGH or 8 hours on LOW, then add the final 20 minutes after shredding. Check the pork for tenderness rather than relying only on the clock.

Build in fresh contrast

Warm the corn tortillas before filling so they are pliable and less likely to split. Keep the filling modest enough that each taco can be lifted and eaten comfortably.

Coriander and diced onion add freshness, while pineapple echoes the fruit in the marinade. Lime wedges let everyone add a sharp finishing squeeze to taste.

Make-ahead planning

The pork can be cooked ahead and stored with some of its cooking juices to help it stay moist. Reheat it gently before assembling the tacos, and prepare the fresh garnishes close to serving.

For a gathering, set out the warm tortillas, pork and toppings separately. This makes it easy for guests to assemble tacos as they eat.

Recipe notes & tips

• Remove the chilli seeds and stems before soaking, as directed, for a smoother marinade.
• Trim excess fat from the pork shoulder but keep some marbling for a tender result.
• Blend the marinade thoroughly so no large pieces of dried chilli remain.
• Warm tortillas just before serving so they stay flexible.
• Keep some cooking liquid with the shredded pork to help it remain moist.

Variations

• Adjust the heat: Use one chipotle pepper for a milder marinade or add another for more smoky warmth.
• Add extra citrus: Serve with additional lime wedges for a sharper finish.
• Use a different tortilla: Swap the corn tortillas for flour tortillas if preferred.
• Prepare a topping: Add shredded cabbage for a crisp, fresh contrast.
• Make it in batches: Cook the pork ahead and warm it with its juices just before serving.

Common mistakes to avoid

• Skipping the soak: Dried chillies can blend unevenly; simmer them for the full 10 minutes until soft.
• Leaving large chilli pieces: A coarse marinade coats less evenly; blend until smooth.
• Shredding too early: Firm pork will resist the fork; let it cook until it pulls apart easily.
• Drying out the meat: Reheat shredded pork with some of its cooking juices.
• Overfilling the tortillas: Too much filling makes them difficult to handle; assemble smaller tacos.

How to store

Refrigerate leftover pork in an airtight container with some cooking liquid for up to 3 days. Reheat gently in a covered pan or microwave until piping hot, adding a splash of water if it seems dry. Store tortillas and fresh toppings separately.
