Slow Roasted Lamb Shoulder

I love a roast dinner – there’s something about it that feels so homely, and with friends of ours coming over for dinner (who have recently emigrated to Hong Kong) I decided to do a traditional British supper to welcome them back to the country.  This time of year is all about Spring Lamb and slow roasting it really shows it off at its best!  Slow Roasted Lamb Shoulder is definitely a firm favourite in our household!Slow Roasted Lamb Shoulder by Emma Eats & Explores - SCD, Paleo, Grainfree, Glutenfree, Dairyfree, Sugarfree, Primal, Whole30, Low Carb, LCHF

The thing I love about slow roasts is that you can’t really go wrong – the time scale doesn’t matter too much – you can under-do it, but it’s pretty hard to over-cook it.  The longer it stays in the oven, the better it gets – perfect if you find yourself having a catch up and dinner gets pushed back a bit!

The cooking guidelines obviously vary with the size of the piece of meat that you use, but mine was 2kgs and was in the oven for 4 1/2 hours.  This sized lamb shoulder was plenty for four of us with lots of left-overs so it probably serves 6!

So how to prepare the meat…  

Start by preheating the oven to 170C (340F).

Begin the prep by chopping the garlic into fairly thick slices – maybe 3 or 4 slices per clove and then place the lamb, fat side up and score small incisions with a sharp knife all over the fat of the lamb shoulder.  Stuff a piece of garlic into each incision along with a small sprig of fresh rosemary.Slow Roasted Lamb Shoulder by Emma Eats & Explores - SCD, Paleo, Grainfree, Glutenfree, Dairyfree, Sugarfree, Primal, Whole30, Low Carb, LCHF

Then layer the anchovy fillets on top of the lamb shoulder.  I promise it wont taste fishy – it just really adds a lovely salty, umami taste to the whole Slow Roasted Lamb Shoulder – I don’t even really like anchovies and you can’t taste them at all!  If you’re really worried about the anchovies then leave them out and just use regular olive oil or butter to drizzle over the lamb shoulder (see later for this step).Slow Roasted Lamb Shoulder by Emma Eats & Explores - SCD, Paleo, Grainfree, Glutenfree, Dairyfree, Sugarfree, Primal, Whole30, Low Carb, LCHF

Slice the onions and layer them on a baking tray along with any leftover rosemary and garlic that you may have.  Place the shoulder of lamb on top of the onions and drizzle the anchovy oil over the whole thing.  Season well with salt and pepper.  Add 100ml of water to the baking tray.

Now you have to enclose the lamb.  Using tin foil, cover the lamb and the tray entirely so that it can steam inside the foil – you want to try to not have any gaps in the tin foil at all.

Pop the lamb into the pre-heated oven and leave to roast for about 4 hours.  After the 4 hours, remove the tin foil and cook for a further 30mins so that the lamb has a chance to brown and crisp up.  You can then pretty much leave it in the oven until you are ready to serve it – you may want to rest it for 10-15 mins when it comes out of the oven so that the juices have a chance to drain.

If you want to, you can make a gravy from the juices and the onions in the bottom of the baking tray.  Collect the juices from the resting lamb and those in the bottom of the baking tray.  Skim off as much fat from the surface as possible.  Blend these with the onions using a Hand Blender then reduce the sauce in a pan (heat on low for about 10-15 minutes) on the hob until it thickens slightly (as I can’t use flour to thicken my sauces).

Doesn’t it look amazing!

You almost don’t need to carve it, it just falls away from the bone, and the fat has all melted and the skin is lovely and crisp.  Give it a try – it’s so easy to make and looks so much more impressive than the actual effort required to cook it.  I’m sure Slow Roasted Lamb Shoulder will become a family favourite in your house too!Slow Roasted Lamb Shoulder by Emma Eats & Explores - SCD, Paleo, Grainfree, Glutenfree, Dairyfree, Sugarfree, Primal, Whole30, Low Carb, LCHF

I served it with potatoes dauphinoise (for the others), Cauliflower Mash, Honey & Thyme Roasted Carrots, and Roasted Fennel for a proper Roast Dinner!Slow Roasted Lamb Shoulder by Emma Eats & Explores - SCD, Paleo, Grainfree, Glutenfree, Dairyfree, Sugarfree, Primal, Whole30, Low Carb, LCHF

I then served my Apple & Cinnamon Crumble for dessert – you can’t get more British than that!  If you love this you’ll love my Slow Cooker Lamb Shanks too!

  11. Jen Enoch says:

    I have to tell you, I’ve never made lamb, mostly because I’m so afraid of ruining it. These steps are laid out so well, I really think I can do it!! Thank you so much for posting this!

    1. You can’t ruin this! The longer you cook it the better!! ?

  12. Erica Price says:

    That does look so tasty. Difficult to beat a good roast and I love how it looks with the rosemary sprigs.

  13. Holly says:

    This looks really good. Lamb is just so expensive.

    1. I find most meat is these days ? – decent organic stuff anyway, but worth it for a special occasion!

      1. Doreen says:

        Emma, I too eat all organic, and yes, it is rather costly here in America too. I didn’t buy myself turkey for our Thanksgiving holiday as it was way too expensive. I instead roasted a chicken. Worked for me!

  14. Oh gosh! It looks delish! I would love to eat it now please hahaha!

  15. Doreen says:

    It looks delicious. Amazingly yummy. I’m American, so silly question, but what is a hob? LOL Also, I would imagine if you leave the roast in a hot oven too long, it would dry out, no? I like a juicy roast.

  16. Brooke says:

    I can smell it through the screen! Looks so yum!!

    I’ve never made lamb, but this I have to try. It looks amazing.

  38. I’ve never roasted lamb before, or cooked it all for that matter. We have enjoyed it in restaurants, though. I love how tender this looks and will definitely have to try it out.

  39. Anne Murphy says:

    I’ve used the slow roast method for beef, but never for lamb. (Well, I don’t cook lamb very often – it’s not that readily available here, and ridiculously expensive…) I can sometimes get it at the farmer’s market, though, so I’ll have to look out for a shoulder and try this!

  40. WOW this is stunning! Bet it tasted great too.

  41. Rosy says:

    Thanks for sharing this interesting food with us, I hardly try new food due to fear so reading about it is almost as good!

  46. mjndiaye says:
