Tender slow-cooked shredded Welsh lamb in a spicy Mexican-style barbacoa sauce, piled onto soft tacos and loaded with toppings.
I’m making a taco FEAST today, and most of the work is done by the slow cooker.
Everyone will adore this special dish. So great for a family get together and it makes a brilliant alternative to the traditional Sunday Roast!

This post was created in partnership with PGI Welsh lamb. All opinions are my own.

Last year Chris and I spent a fantastic couple of days down in south Wales, learning all about lamb.
We visited the Salt Marshes at Gower Salt Marsh Lamb and made this delicious slow roast shoulder of lamb with it when we got back home.

Now we’re working with Welsh lamb again!
You may not notice, but we do very little brand work. We work with just a handful a year, so we only pick our absolute favourite brands to work with.
We adore Welsh lamb, so that’s why we’re working with them again!

This time I really wanted to show of the versatility of lamb and how it can take on some seriously big flavours. So we’re going Mexican and making these amazing barbacoa-style lamb carnitas tacos.

What do we need?

  • 2 kg bone-in shoulder of Welsh lamb
  • For spicy rich heat – adobo paste and chipotle paste
  • Aromatics and spices – garlic, cumin, ground coriander, dried oregano, ground cloves
  • Chicken or lamb stock
  • Salt and Pepper
  • 2 Limes

To Serve:

  • Soft tacos – I like to warm them in the oven or brown them on the griddle or homemade flatbreads.
  • Plenty of choices for toppingsmy favourites include: red onion, fresh coriander (cilantro), jalapenos, cherry tomatoes, sour cream, salsa, guacamole and lime wedges.

  • Transfer to a slow cooker and cook on low for 8-9 hours or high for 6 hours (see tip in the recipe card for cooking in the oven).
  • Remove the lamb from the slow cooker and shred the meat using two forks.

  • Serve with wedges of lime.

Don’t be shy with those toppings now.
And be sure to drizzle on some of the cooking liquid from the slow cooker – it tastes AMAZING. In fact, I like to include little individual bowls of the cooking liquid for dipping.

Notes

Cooking in the oven rather than the slow cooker:
If you don’t want to cook the lamb in a slow cooker, you can cook it in a heavy-based, oven-proof pan, with a lid, in the oven at 160C for 3 hours.
Add an extra 180ml (3/4 cup) of stock and check a few times during cooking to ensure the lamb doesn’t cook dry. Add good splash of boiling water or stock if it starts to look too dry.
Can I make it ahead?
Yes – you can make up the carnitas right up to the point you shred the meat. Then cool, cover and refrigerate the lamb for up to two days. 
Cool, cover and refrigerate the cooking liquid too.
To reheat, fry the lamb in a large frying pan in two tbsp of oil until golden and piping hot throughout.
The cooking liquid can be reheated in a saucepan until piping hot.
Can I freeze it?
Yes. Make up the carnitas right up to the point you shred the meat. Then cool, cover and freeze.
Freeze the cooking liquid too (leave a little space in the container as the liquid will expand slightly upon freezing.
Defrost in the refrigerator overnight, then reheat as per the ‘make it ahead’ instructions above.
How to scale down this recipe to serve fewer people
If you want to scale down this recipe for 2-3 people (around 6 tacos), replace the lamb shoulder with a half shoulder joint or 2 lamb shanks. Reduce the all of the other ingredients by one quarter and cook in the same way.

    Delicious. Would recommend drinking the juice from the lamb afterwards. A proper cockle warmer

    I made a few changes but followed all the measurements to a tee. I switched the cloves to cinnamon, added extra lime juice and half an orange. Had some spring onions in frig so I threw those in too. This is a delicious recipe! Looking forward to making this at our next Sunday Brunch. Thank you!

    This is the most tender lamb I’ve ever cooked and it goes perfectly crispy in the pan. I couldn’t find the adobo paste but it’s still full of flavour without it. The lamb goes beautifully in tacos and burritos. I also like to use this lamb in my own rice concoction with pepper, carrot, red onion, garlic, egg, coriander and turmeric 😋

  7. Juan g says:

    I would not add sour cream or guacamole I used for chips as a appetizer?

  8. simon says:

    Not sure where I’d purchase Adobo paste from as I’ve never seen it in the shops?

    1. Nicky Corbishley says:

      It’s normally in the spice aisle of larger supermarkets in little jars. In the mexican section, or with other paste jars (such as chipotle and tamarind paste).
