Serving: 2
Prep Time 5 mins
Cook Time 4 hrs 30 mins
Total Time 4 hrs 35 mins


  • 2 x lamb shanks
  • 1 x onion
  • 1/2 cup gravy powder (I use Maggi Rich Gravy Mix)
  • 1.5 cups water
  • salt and pepper to taste
  • 1-2 sprigs fresh rosemary


  • 1. Spray slow cooker base with cooking spray. Slice onion in half, one half slice in half rings, the other half dice.
  • 2. Place the sliced half rings on base of slow cooker, then place lamb shanks on top of the onions.
  • 3. In small saucepan, saut the diced onions (and yes I do believe it adds a depth of flavour to the dish to do this step, but of course it is optional). Pour these sauted onions on top of the lamb shanks.
  • 4. In same small saucepan blend together the gravy powder and the water and season with salt and pepper if desired then pour this over the lamb shanks. No need to heat or cook this gravy, just blend it - just use the same saucepan to save dishes ๐Ÿ™‚
  • 5. Place your rosemary into the slow cooker.
  • 6. Cook on HIGH 4-5 HRS or LOW 6-8 HRS.
  • 7. Serve on a bed of mashed garlic potatoes.
  • Note: If you want to you can add 2 TBS of French onion soup mix to this but I prefer it simple.

  1. Hello I’m concerned about how much gravy powder to put in, I can only buy 27 gram sachets of Maggie roast meat gravy, which I love ๐Ÿ™‚ but 1/2 cup seems a lot. So could you tell me how many sachets I should use. Keeping in mind 1 sachet is 27 grams. Hope you can help. Regards Kerrie Martin

  2. Love love love this recipe! I use a little less gravy powder however maybe 1/3 of a cup (gravox traditional) as it was slightly too rich the first time. As I have made it a few times I havent always had the fresh rosemary available so I have made it both without and with dried rosemary and its equally delish! Thanks for the recipe!

  3. Love this Recipe! I made it for 4 people and used 2 cups of water, 3/4 cup of Red Wine and 1/4 cup of port. Amazing!!! This will be a favourite for years. Thank you

  4. Wow, this was absolutely fabulous!

    I added some garlic to the onions when I fried them with a stock pot and I mixed a packet of brown onion soup to the water and added that to the cooker. Did not add extra salt.

    This is so on my favourites list!!!

  5. This is the lamb shanks recipe I’ve been looking for! Really tender lamb and a tasty rich gravy. Once the lamb was cooked, I moved the gravy to the hob to thicken and added cornflour. I’ll definitely be making this again.

  6. It was obsolutely delicious. I did my own tweets to it. I didn’t have the rosemary substituted it with homemade gravy as far as used 3 tablespoons of flour , pepper and salt to taste beef bouilion packet.
    I added 1 green peppers sliced, carrots closed thin, and fres garlic. It turned out to be very tasty and delicious. I will definitely go this once a month to add verity to my dinners. What a wonderful choice to add to your recipes!!

  7. This was a crowd pleaser in my family. This dish finally pushed my husband into believing in a slow cooked meal. Thanks again ladies for giving me yet another yummy recipe ๐Ÿ˜๐Ÿคฉ๐Ÿ‘Œ

  8. We tried this tonight for the first time and it was really nice, it got the tick โœ… of approval
    Next time I will add some mushrooms but it was so good

  9. Hello . Iโ€™m wanting to make this but canโ€™t get the maggi gravy in the supermarket in the uk. Only available on line Can you suggest an alternative please & how much & how to make it up ?
    Many thanks Laura

  10. This is so delicious! I added fresh diced garlic as garlic is my thing and I put it in everything! I also used the Maggi deglaze gravy and it was heaven on mashed potatoes. Will definitely make again and might also try it with a boneless lamb roast.

  11. Reviewed in 2019, but it’s still delish! Served with rice, steamed carrots and baby spinach. So easy and enough leftover gravy to slow cook some meatballs or make a savoury mince! There’s only the two of us so this recipe is great.

    Fantastic recipe. Almost too easy to prep and walk away for the end result. Meat was so tender and the gravy perfect. I added half a packet of salt reduced french onion soup (personal preference) but will try without it next time. Hubby has already asked for these again. Thankyou for a great fuss free, tasty recipe.
