wow, this was amazing. didn’t change anything, did as recipe states. the sauce poured over my mash and veg, beautiful

Absolutely delicious

Yes we often do Chicken obsession. I still use the mushroom soup myself and it’s amazing but you can use chicken if you want πŸ™‚

Could you do this with chicken and use condensed chicken soup?

I made this for my family. We only had a small roast so I added some more chops. Omg will be definitely cooking it again.

If you are worried it will taste like mushrooms – don’t worry πŸ™‚ Every day I see adamant mushroom HATERS assure me they never tasted it and even feed it to unsuspecting mushroom hating partners and they never guess hahaha
If it’s allergy related you can swap to cream of chicken but it’s not as good

Is there anything else I can use besides the can of mushrooms????

Tried for first time today and sauce was absolutely delicious, I didn’t make any amendments.
My lamb leg was a bit fatty so would use different cut next time.
Will definitely make again.

I must be the only person that doesn’t like this recipe. Meat was lovely but I did not like the sauce. Think it may have been the french onion soup. πŸ™

Love this recipe, so tasty, works so well with a leg of lamb. I’ll never cook a leg of lamb any other way! Big hit with the family. Leftovers great on toast or sandwiches the next day.

This has been a big winner in this house for years now πŸ™‚ my children and I absolutely love it as well as other family and friends it’s amazing πŸ™‚ I wish lamb was cheaper to have more often haha we usually cook roast veggies to go with it and we even had it for Christmas one time and was a massive hit

Had Lamb obsession with leg of lamb omg was just awesome lovely flavours wont do any other way yummy


April 21, 2020

Cooked this today with rump and it was amazing. Didn’t add the mint sauce because I didn’t have any. I have prepared this as a dump bag and just added veggies and it was amazing. Definitely lived up to the all the reviews and will be doing this again

I’d cook it all day on low πŸ™‚ 9-10hrs at least


December 19, 2019

I have a 3kg leg of lamb, how long should I cook this for please?


July 27, 2019

I made this for the family for the 1st time it was so delicious the meat was super tender and just fell off the bone. So easy to prepare I did leave the mint sauce out though as we don’t like it .
Definitely a winner for our house


January 14, 2019

Absolutely amazing and so easy


December 6, 2018

So I’ve made this several times and thought I’d better leave a review. WOW! What a super easy yet super tasty dish..we love it! Made with both a roast and chops. Make the juice into a gravy. Mmm. Husband calls it Lamb Delicious! Even got my mum onto it!

It’s not often I rave about a recipe but this one deserves all of the 5***** reviews it has been given. I used a lean leg of lamb and it fell off the bone it was so tender. The Obsession Sauce is to die for. I carved the meat and put it back in the sauce for the last 30 minutes and served it with new potatoes, runner beans and carrots. Abolutely gorgeous!

HUGE FAMILY FAVE!! Meat literally falls apart. The leftovers (if any!) are the most devine pie filling for the next nights dinner.


June 25, 2018

Love it. ❀️❀️
I use roast lamb, trimming most of the fat off. Remove any bones and shred meat , and mix through the sauce, serve with mashed potato and veggies. Yummy. πŸ˜‹

Oh and if any left overs, it makes amazing toasties/jaffles.

OMGEEE!!This was the most amazing Leg of lamb I have ever had..cooked a 2kilo leg using the “lamb Obsession”recipe..how something so easy an quick to prepare with minimal ingrediants can taste that good is just AMAZING!!!
LOVED this..LOVED everything about this.
10 out of 10😁😁😁

Steph if you go to the original recipe and have a look at the comments below it you’ll see dozens of people all leaving feedback that there is zero mushroom taste and they feed it all the time to unsuspecting mushroom haters who never once detect it … trust us… he won’t taste it πŸ™‚


May 22, 2018

Love the sound of this but hubby won’t touch mushrooms. Any suggestions for replacement soup flavours? Thinking tomato perhaps?

You can do it all on low for sure πŸ™‚ If it’s a large roast it can easily handle more hours 8-10hrs on low


May 13, 2018

I’m going to try lamb roast do I have to cook on high for 2 hours first or can I cook for 8 hours on low as I work

Janet Miller

March 13, 2018

We had this for dinner tonight. BEAUTIFUL!!!! Everyone enjoyed it. Will definitely be having this again. πŸ˜‹πŸ˜ƒ

Yes it will cook happily for 6-8hrs on low easily πŸ™‚

Can I just cook on low for longer as I won’t be home to change the settings?


February 23, 2018

Did this with chops last night. Husband said I can cook it every night only there was one problem. NO Leftovers bloody beautiful. Will certainly be having this again. Might try small lamb roast next time.

Tried this for the first time tonight and was so happy with the result! This is absolutely beautiful, so yummy and devoured by my family! It’s so easy too which is an added bonus! This will become a regular for us! πŸ˜€

I made this with a lamb shoulder. It was amazing! My favourite slow cooker meal so far. The meat easily shredded, plenty of sauce, so easy to do.
I ate it with fresh bread.


June 25, 2017

Made this up with a leg of lamb before we went out to the footy today and 8 hours later when we arrived home it was ready. The meat fell apart and was SO succulent. Thankyou for a super easy and delish meal x

Sorry I missed your question until now
I find it easily shreds the same was as you’d do pulled pork if cooked long enough
Or you can slice it like a roast style πŸ™‚


June 10, 2017

Ok so I have just put this in on, my first time making it (I’m not lover of lamb) but the people I’m making this for are. I’m using a lamb shoulder roast.
My question: will this fall f the bone & do I just use forks to seperate it ( like I do for the pulled pork?
Please & thank you

No not needed πŸ™‚


May 29, 2017

Trying this for the first time, just wondering if I need the teatowel under the lid please?

Any roast size piece of lamb of any kind will work πŸ™‚


April 9, 2017

Is this just using a normal leg or lamb with the bone in?

I made this with roast veg and some steamed veg for visitors and they raved about it. Really delicious the flavours were just beautiful together.

OMG Family loved it. My 7yr old son even commented “the meat is so nice and soft, it melts in your mouth”.

Paulene @ Slow Cooker Central

February 15, 2017

Give it at least 4hrs on low (after the 2hrs high) if its’ a smaller roast like around 1kg or go the 6hrs if it’s closer to 2kg or above πŸ™‚


February 14, 2017

First time obsessor here! How will I know if my lamb will need 4, 5 or 6 hrs on low ? I’d like the meat to melt in my mouth and be easy to cut. Thanks. πŸ™‚

Family loved it, used spring vegetable soup mix instead, definitely cooking again.

hahah kids are like that with names they remember hey πŸ™‚


November 20, 2016

This is a favorite in our house although my 6 year old calls it fireman lamb. No idea why but happy for him to call it whatever he wants if it ends in a clean plate (which it always does)

hahah love it! πŸ™‚


October 13, 2016

This is absolutely delicious and is now a regular in our house hold. Just need to get my portion sizes under control as it is hard to stop

Omg this is amazing!!! The lamb was so tender and the sauce was absolutely delicious. This will be a regular in my house I am making it again next week

Neil all lamb will be oily by nature of the meat.
However there are several ways you can help to prevent or limit it in your finished dish πŸ™‚
How can I remove excess fat/oil from my slow cooker dish?

Neil Sheppard

I really want to try this but EVERY time I cook lamb for my family they say “It’s too fatty” or “It’s too greasy” Does this turn out fatty / greasy?

Am about to find some lamb roasts in freezer and thaw out for cooking tomorrow!! I must check that I have Mushroom soup, Im going to add some fresh mushrooms too just because I love them.


April 30, 2016

Did this with a rolled Lamb Shoulder Roast and smashed it out of the park. Will get a bigger cut next time and double up.

Paulene, you’re a genius!
