Choosing the Right Cut of Lamb

While you can use different cuts of lamb for slow cooking, nothing beats shoulder when making Crockpot Lamb Barbacoa Tacos. This particular joint comes with the perfect mix of fat, connective tissue and meat, which breaks down beautifully over several hours. It holds up well during the long cooking time and rewards patience with unparalleled tenderness. 

The bone-in aspect matters too: it enhances the flavour of the final dish while giving the sauce a depth that boneless alternatives can’t match. Trimming excess fat beforehand is key, but don’t be too aggressive. Some fat is essential for moisture and richness. Once the lamb has cooked and rested, you’ll find it easy to pull apart. The result? Juicy shreds packed with flavour, perfect for folding into warm taco shells.

Making the Most of the Sauce

The sauce created in this recipe deserves just as much attention as the lamb itself. In Crockpot Lamb Barbacoa Tacos, the sauce isn’t just an afterthought. It’s the glue that binds all the elements together. It starts as a marinade, then turns into a braising liquid, and finishes as a glossy, punchy reduction

Reducing it after the lamb is cooked intensifies the flavours and gives the meat a final coating that clings to every strand. Don’t rush this part. The liquid should bubble gently and then thicken slightly as the flavours concentrate. If it reduces too far, a splash of water or stock brings it back into balance. A great sauce makes each bite more vibrant, transforming tacos from tasty to unforgettable.

Taco Shells and Tortillas: Choosing the Right Base

The base of your taco matters. For Crockpot Lamb Barbacoa Tacos, a soft corn tortilla works best. It’s pliable, flavourful, and holds the meat well without tearing. Warm it briefly on a hot, dry pan to soften and develop flavour. If you prefer crunch, hard taco shells also work. Just be aware they can crack under the weight of juicy lamb and toppings. Flour tortillas are another option and tend to be more forgiving if you’re feeding a crowd. 

Whichever you choose, make sure they’re warmed just before serving. A cold taco shell dulls the flavour and texture, while a warm one enhances both. Keep them wrapped in foil or a clean tea towel to retain heat. The tortilla is the vessel that holds everything together. Don’t overlook its importance.

Taco Toppings

A great taco is more than just its filling. The toppings you choose for Crockpot Lamb Barbacoa Tacos should enhance, not overpower. Start with contrast: the lamb is rich and spiced, so cool, fresh additions work well. A sharp pico de gallo gives brightness and crunch. Guacamole offers creaminess and subtle richness. Meanwhile, a drizzle of lime crema adds a cooling element that ties everything together. 

If you enjoy heat, sliced jalapeños or a hot sauce work beautifully. If you want to add texture, try finely shredded cabbage or pickled onions. They cut through the richness and keep the tacos lively. And finally, a handful of chopped coriander or parsley brings a touch of freshness. The key is balance: each topping should support the lamb, not compete with it.

Great for Batch Cooking

One of the best things about Crockpot Lamb Barbacoa Tacos is how well they lend themselves to batch cooking. The slow cooker allows you to make a large portion without extra effort, and the results reheat beautifully. The flavours deepen overnight, so leftovers often taste even better

You can divide the lamb into meal-sized portions and freeze them for later. Simply defrost and reheat on the stove with a splash of water. This makes them ideal for meal prep or feeding unexpected guests. You can also repurpose the lamb beyond tacos: try it in quesadillas, rice bowls, or even stirred through pasta for something different. Versatile, flavourful, and easy to store, this recipe is a brilliant investment in future meals.

  • 1 tsp sea salt
  • ½ tsp ground allspice
  • ½ tsp freshly-ground black pepper

For the lamb:

  • 1.5 kg bone-in lamb shoulder joint
  • extra-virgin olive oil
  • 1 large onion, finely chopped
  • 6 garlic cloves, finely sliced
  • 1 extra-large orange, juice and zest
  • 1 lime, juice and zest
  • 1 tbsp apple cider vinegar

  • 1 litre water
  • 2 dried bay leaves

Instructions

You will need a Crockpot Sizzle and Stew Slow Cooker. Buy yours here.

  1. Combine the spice mix ingredients in a small bowl.
  2. Score the fat on the bone-in lamb shoulder. Season generously with sea salt on all sides. Drizzle with olive oil and spread to cover.
  3. The Crockpot Sizzle & Stew has a hob-safe bowl, so you can sear and slow-cook from start to finish with just one pot. Added bonus: it’s easy to clean and is dishwasher safe!
  4. Heat the hob-safe bowl over medium-high heat. Sear the lamb shoulder until browned on all sides. Transfer the browned lamb to a large plate.
  5. Reduce the heat to medium-low. Add the onion and cook, stirring occasionally, until softened and starting to brown, around 10 minutes.
  6. Add the garlic and cook, stirring constantly, for 1 minute, then add the spice mix and cook, stirring constantly, for a further 30 seconds. The short cooking time will ensure that you don’t burn the spices, which would make them, and thus the finished recipe, bitter.
  7. Add the remaining ingredients – orange juice and zest, lime juice and zest, apple cider vinegar, sugar, water, and dried bay leaves – and stir to combine.
  8. Return the browned lamb to the sauce. Cover with the lid and bring to a simmer, then transfer the hob-safe bowl straight from the stove to the slow cooker. Cook on the high setting for 4 to 5 hours, or until fall-apart tender. Note: the Crockpot Sizzle & Stew has high, low and keep-warm settings, which offers great control over every meal.
  9. Remove the lamb from the sauce and let rest for 15 to 20 minutes. At this point, the lamb should be so tender that the bone slips right out and the meat will be juicy and tender.
  10. Remove the lid and return the hob-safe bowl to the stove. Reduce the sauce over high heat for 15 to 20 minutes, stirring occasionally.
  11. Once the lamb has rested, shred it with two forks, discarding any large pieces of fat. Return the shredded lamb to the sauce and stir to combine. Taste and adjust seasoning, to your liking.
  12. Return the hob-safe bowl to the slow cooker on the keep-warm setting while you toast your tortillas and prep your toppings. Serve family-style and enjoy!
