  1. Curious, could throwing in other veggies as well as the carrots work too? I’ve got a fussy toddler to feed and veggies always end up on the floor haha.

  2. Hi just wondering if the 1 cup of beef stock is the only liquid in this recipe? Just doesn’t seem enough liquid to cook properly? Not wanting to stuff it up! πŸ™‚

  3. Loved this.
    I used gravy flour to thicken the cooking liquid into a gravy and added an extra slug of wostershire sauce and tomato sauce.
    Easy recipe as I always have these ingredients in the pantry.

  4. This recipe is excellent. The sauce has a lovely flavour and it’s a very affordable family meal.

    Thank you Gail

  5. We had this for dinner last week and it was very yummy with lots of flavour… So this week my dad asked if you could use Turkey legs. We had it for dinner tonight with Turkey legs and the only ingredient i changed was the Beef stock to Chicken stock and was yummy… I’m not a fan of turkey as i find it too dry but this just fell apart…. Only problem with turkey is that it is also very filling….

  6. This was a real winner!! Followed the recipe except for the carrots and thickened the sauce with 3 tablespoons of instant chicken gravy with 30min to go. Delicious!!

  7. I love this recipe and so did the whole family! So easy to throw together too. I use beef instead of lamb shanks and serve on mashed potato. Thanks for sharing! πŸ™‚

  8. I made this recipe the other day, deeeelish! I used a tsp of powdered beef stock instead of liquid stock , a can of chopped tomatoes, a clove of garlic and two tiny red chillies, it was a hit. And the gravy on mashed potatoes is super yum, thanks for an easy shanks recipe

  9. Divine. It was so flavoursome and the meat simply fell off the bones. We are putting this in our favourites to have again.

  10. I added a teaspoon of chilli flakes and a teaspoon crushed garlic, thickened liquid with a little cornflour..absolutely fantastic

  11. We have these about once a fortnight. Absolutely delicious! Such an easy and tasty recipe. I always keep the leftover gravy and have it with sausages the next night. Can’t wait to try it with beef.

    I cooked this dish today but substituted the lamb shanks with 6 chicken drumsticks. I also usd the low salt variety of the onion soup mix. I cooked it on low for 8 hours & thickened the sauce with cornflour. I served it with sweet potato mash & steamed broccoli. A very enjoyable meal.

  13. Absolutely scrumshussss! I was ready to put my slow cooker away in the cupboard or give away bcoz i hadn’t made anything that i found absolutley delicious, until this, slow cooker definately staying ??

  14. Fantastic recipe with store cupboard ingredients. I made a slight change in not reducing the sauce towards the end, instead, I removed the shanks (I used homegrown hogget) and added cornflour to make a thicker sauce. Blitzed the cornflour into the remaining liquid. A wonderful autumn touch to the meal.

  15. I love this recipe, at the end I make a slurry of plain flour and water and add it to the juices to thicken and make a gravy. Amazing

  16. Just finished eating this tonight and everyone cleaned their plate! So easy to make. I followed the recipe to the letter except I took the meat off the bones at the end, added some cornflour to the liquid and then returned the meat to the slow cooker while I served up the mash and green beans. Perfect Sunday dinner on a cold winter’s night

  17. I’ve never been a big fan of lamb shanks, UNTIL NOW! This recipe is amazing and so full of flavour. If I could give it more stars I would.

  18. First time making these tonight, they were amazing, the whole family loved them, will definitely make again.

  19. I decided to try this one tonight, only change I made was the Onion as my son isn’t a fan of it (33 yrs old, yeh I know hahaha) so I substituted the onion with cherry tomatoes and wasn’t disappointed, very nice if I say so myself… 5 stars for sure

  20. Family enjoyed this great recipe. Easy to make. I tweaked slightly, in that I cooked on low for 8 hours and thickened with a cornflour slurry 20 minutes before serving with kumara mash and green vegetables

  21. I cooked this last night
    Seared four lamb shanks,double all sauce ingredients. Four and half hours on high.

  22. If I’m only cooking 2 do I still do the same cooking time, obviously I’ll half the other ingredients πŸ™‚

    Loved this recipe.
    Not too much tomato flavour in it, not salty either. The meat fell off the bones, melt in the mouth.
    Another meal on repeat.
