Slow cooked roast lamb with gravy


May 2, 2017

Tender juicy roast lamb with the most delicious gravy

  • Prep: 10 mins
  • Cook: 4 hrs
  • Yields: 6-8 servings


Lamb leg roast 900g to 1kg (see notes)

2x cups of beef stock

2tsp minced garlic

2x sprigs of thyme or 2 tsp dried thyme

1x sprig of rosemary or 1 tsp of dried Rosemary

1tsp dried parsley

Salt and pepper


1Place all ingredients into a slow cooker and cook on high for 3 1/2 to 4 hours.

2When the lamb meat looks like it's falling off the bone it's ready.

3I placed my lamb on a tray and covered it with foil to rest for as long as possible and finished it off in the oven on 180deg for 10 mins to warm it back up and to get the outside of the roast crispy but that is completely optional.

4See the notes section on how to use the delicious stock that's left in your slow cooker for a delicious lamb gravy.


1Make sure you check the size of your slow cooker to make sure you purchase a lamb roast that will fit.

2The stock left over in the slow cooker makes an amazing gravy, I ladled 2 cups into a saucepan and thickened it with my favourite gravy powder. Roast meat gravox powder has given me the best flavour. I use about 4-5 tablespoons and whisk it really well to help prevent those lumps and then add some salt and pepper to finish it off. As soon as its nice and thick its ready to pour all over your tender roast lamb.

Made this yesterday. What a gorgeous dish.! The family gobbled it up, even the fussy child. Makes a beautiful gravy as well.

Made this today. I used 2.5 kg leg. Flavours were perfect! Also made gravy from the liquid once cooked. Whole family loved it!

If that’s all you have I’d use it – it’s more a salty flavour booster than actual chicken tasting I find ๐Ÿ™‚

Hi I only have chicken stock will this work๐Ÿ˜ฌ or will it give it a whole different flavour

This is now my go-to roast lamb recipe. It’s so tasty and tender, and the gravy is a complete winner too!

A very good recipe and the lamb was absolutely delicious and gravey was nice as well and i used 1 cup of beef stock and 1 cup of chicken stock in the slow cooker and the smell of a leg of lamb and mixed herbs was so good

Loved this recipe! I rested my 1.5kg roast on some peeled and halved potatoes and a couple of whole peeled onions. Cooked on high for 1 & half hours, then 5 hours on low. Lamb was succulent served with pumpkin, sweet potato and beetroot baked in the oven, & steamed veggies. The gravy made with the meat juices was delicious! Will definitely do it again. ๐Ÿ˜‹

This is now my go-to roast recipe, Iโ€™ve made it several times and itโ€™s a hit every time. I multiply everything by 2.5 since I do a 2.5kg roast, and cook it for roughly the equivalent of 10-12 hours on low (I usually have some combination of high & low depending on how much time I have!). I use vegetable stock instead of beef as itโ€™s less overpowering. Thank you for this recipe, itโ€™s awesome!

Lamb is quite possibly my favourite roast meat and this was absolutely beautiful. My piece of lamb was a click over 1kg, cooked for 4 hours on the dot. Made the gravy as per recipe which really finished it off. Family loved it, will definitely make again!

Omg what can I say this dish is absolutely delicious .. This is a 10/10 for sure itโ€™s definitely my new Sunday night toast..

Wow. I was a little hesitant since other recipe’s suggest searing, and slitting the leg and massaging ingredients in. I literally just threw the leg in, poured the stock in and counted out the herbs. 5hrs later (1.5Kg leg), it was incredibly good! Blown away!

Great recipe! Thanks for sharing. I didn’t have any thyme so substituted with marjoram. The lamb was so juicy I didn’t bother with gravy.

Made this Saturday night. Made up my own beef stock with stock cubes so the beef stock wasn’t as over powering and used Tuscan seasoning and garlic granules from the pantry. Was bang on! Usually don’t like lamb but was so tender and delicious it was just falling off the bone. Leftover stock and juice made the yummiest gravy. Deff 10/10 and so easy to do!

Beautifully tender lamb and the gravy was to die for! Personally i think the beef stock overpowered the lamb a little bit so might try vegetable stock next time. Still giving 5 stars because the recipe is bang on!

Looks yummy! Do you use lamb leg with or without bone??


July 31, 2017

Do you rub the herbs on the lamb or just in with the stock? And do you turn the lamb? Thanks

Made this tonight for dinner and it was fantastic, we loved it. The gravy was awesome as well, though I did only use half the beef stock it was still more then enough for the 2 of us. This is the way my lamb will be done in future just delish !!

I would do around 8hrs on low


June 30, 2017

How long would I cook this on low please
