I like to serve this meal with some mashed potatoes and gravy (which is made with the lamb sauce) and a salad. 

Also you can serve it with a salad of your liking. 

how to cook lamb shoulder in the oven

Let the oven do the work, while you do whatever else it is you need to do for the day/evening. 

But please for the love of GOD do not leave the house with the oven on.

This results in way to many house fires each year and I do not want to be responsible for that. 


It is REAL easy, since everything is down in one pot.

Basically all your going to have to do is spend less than 5 minutes seasoning it, then you will want to cover it with a oven safe lid.

Or if you want you can use tinfoil as well, just make sure their is a gab to allow the air to circulate around the lamb

You will make it the exact same way as you would in the oven. Except you will want to cook it longer, since it is really slow cooking in the crock pot. Anywhere from 8-10 hours would be ideal. 


I would say one lamb shoulder the size of 2.25kg should serve 6-8 people which is better lamb shoulder or leg

NO, it is not recommended to give any dog cooked bones of any kind. They can splitter and be a choking hazard. I like to give my dogs raw chicken and beef bones though. These can be found at your local butcher or at a raw feed dog food store.

First time doing a shoulder and gravy from scratch. Used red wine. All turned out great. Lamb beautiful and tender. Thanks for sharing it. This was an amazing way to cook the shoulder of lamb. My oven must be a little hotter because it was done after 3 hours but I was really amazing. This recipe is a keeper for sure

I made this recipe as the first meat to give to my baby… after it was fished cooking I took the bones out and put it in my ninja to pureé I then froze it in portions to save and then warmed up to feed to her for lunch and dinner… she loved it.

Can you please provide me with recommendation for the cooking time based on the weight of the joint? I have half a lamb shoulder and don’t won’t to over cook it. Cheers!

I believe you can make great food with everyday ingredients even if you’re short on time and cost conscious. You just need to cook clever and get creative! Read More

Can you cook this 2 days before (a Friday) and reheat on the Sunday? If you can, would I follow the recipe up to stage 5 and keep the lamb on the onions in fridge, ready to reheat. Thanks

Lamb shoulder is cheaper, juicier and easier to roast than leg. Infused with rosemary garlic flavours, this is not the sort of roast for craving, just pull the meat off with tongs. Make Truly Crunchy Roast Potatoes while the lamb is resting! Recipe video below

Thanks for your question. As the lamb is slow-cooked, the cooking time doesn’t need to be as exact as with other methods of cooking. For a half shoulder, we’d suggest around 4 hours.

I simply want to say I am just very new to blogging and site-building and seriously savored this web page. Very likely I’m planning to bookmark your site . You certainly have remarkable posts. Regards for sharing your webpage.

Thanks for revealing your ideas. I would also like to state that video games have been at any time evolving. Modern technology and enhancements have served create realistic and enjoyable games. All these entertainment video games were not actually sensible when the concept was first being used. Just like other kinds of electronics, video games way too have had to progress by many years. This itself is testimony to the fast development of video games.

Next time I read a blog, Hopefully it won’t disappoint me just as much as this particular one. I mean, Yes, it was my choice to read, but I really thought you would probably have something useful to say. All I hear is a bunch of whining about something that you could possibly fix if you weren’t too busy searching for attention.

An intriguing discussion is definitely worth comment. I think that you should write more about this subject, it might not be a taboo subject but typically people do not discuss such topics. To the next! Kind regards.

I really love your website.. Excellent colors & theme. Did you develop this web site yourself? Please reply back as I’m planning to create my own personal website and would love to find out where you got this from or exactly what the theme is called. Cheers.
