Slow Cooker Lamb Leg
Slow Cooker Lamb Leg – slow-roasted succulent lamb meat with the well-browned and crispy exterior; flavored with creole seasoning, garlic, and rosemary. A recipe with minimal prep but delivers great flavors in every bite.
When it’s the holidays, the meat that is always a highlight on the dining table is either Ham, Turkey, or beefy Prime Rib Roast.
I totally get it. Don’t get me wrong. But here is a great addition for your holiday table – slow cooker lamb leg. One of those main cuts of meat that is readily available this time of the year and doesn’t require an oven. Freeing up oven space.
Slow-cooking makes it tender and fall part and roasting it in the oven on broil for another 10 minutes gives it an additional beautiful browning and added crispiness.
Oh, you can barely taste the “lamb-y” flavor that most people complain about.
The garlic and rosemary mixture permeates every inch of this lamb meat and that added wine, too; making it to soooo flavorful in every inch of it.
Why choose the boneless leg of lamb?
Boneless leg of lamb is the perfect choice for this recipe and for oven-roasted lamb recipes. It cooks faster compared to bone-in lamb leg and aside from which, you’ll also attain the exact doneness you want.
But if you want to offer both medium-rare and well-done on a single lamb leg cut to cater to your guests’ preference, you may want to go with Bone-in Lamb Leg as each meat’s ends cooked in different temperatures.
Boneless lamb legs can also be butterflied easily and be able to season the meat inside out. I got mine already butterflied. Had to remove the strings to season.

How to cook a leg of lamb?
Prep the Lamb Leg
- Rinse and butterfly the lamb: Rinse the leg of lamb, then pat dry with a paper towel. (Photo 1)
- Butterfly or split it open. Generously salt and pepper inside and out of the lamb, then season with salt and pepper or this Cajun Creole seasoning. Set aside. (Photo 2)
Marinating the Lamb Leg
- Rub the lamb with salt: Make sure you rub the salt deep into as many cracks and crevasses as possible. Mix together minced garlic, rosemary, thyme, and white pepper. Rub the lamb with garlic mixture until it’s evenly distributed in the whole leg. (Photo 3)
- Tie it up and Marinate: Double the garlic, rosemary mixture if you like your food well seasoned. If time permits it’s best to let the lamb marinate overnight so it permeates every inch of the lamb. Tie it up to achieve regular shaping lamb to make sure it cooks evenly. (Photo 4)
Prep and Slow-cook
- Prep the stock: Add about 1 cup wine or chicken stock in the slow cooker, followed by onions, bay leaf, and celery. (Photo 5)
- Start Slow-cooking: Place the marinated lamb in the crockpot then slowly cook for about 5 -6 hours on low. (Photo 6)
- Transfer: Remove meat to a serving platter and pull apart with forks until you have chunky shreds of meat. Alternatively, you can roast in the oven. See notes for cooking times and temperature.
Make the Roux (Photos 7-8)
- Add flour and mix: Heat a saucepan or skillet with butter over medium-high heat. Gently whisk in the flour to make a “roux.” Stir the roux for 2-3 minutes to remove any raw taste of the flour.
- Gradually add liquid: Add about a ¼ or more of liquid and continue whisking until the mixture is thick and somewhat smooth as seen above. Then add the remaining liquid and adjust thickness to personal preference – season with salt and pepper. Remember gravy thickens as it cools down.
You’ll never regret having this delicious and affordable meat on your table. This would become one of your most-requested recipes. Trust me, you’ll definitely love this!
And of course, if you have some leftovers (which I doubt you will 🙂 ), you can use them on sandwiches along with the gravy and some burritos. Now go grab your fork and knives. Dig in!!!

Tips & Notes:
- When choosing a lamb cut at your local butcher’s market, go with the leg of lamb particularly the sirloin-end legs that start at the hip and start at around the knee.
- Boneless lamb leg cooks faster than bone-in lamb leg and it’s easier to hit your desired exact doneness.
- After choosing a boneless lamb leg, make sure you have it butterflied (split open and rolled out) so you can season thoroughly the lamb meat both inside and out.
- To allow the meat to absorb the flavor well, season the meat at least 45 minutes before cooking it but marinating it overnight does deliver a very good result.
- You can season the meat with your preferred spices but lambs usually taste better when seasoned with one of the following: rosemary and garlic mixture, Chinese five-spice, and Harrisa.
- After seasoning your lamb inside out, make sure to roll it and tie up to achieve a regular shape during cooking. Irregular shapes lead to uneven cooking, so take note of that.

So so tasty! I had a 2 lb boneless leg so I checked the internal temp after 3 hours in the crockpot on low and it was totally done. I probably could have gotten away with taking it out 15-20 mins earlier. Even though it’s slightly more well done than I usually like my lamb, it’s super juicy and the flavor is incredible. I’m always intimidated by cooking meat that isn’t ground lol but this recipe was so easy to follow and I’m proud I did it!
Sounds amazing to hear about your exprience. Thank you for your words:)
I added fresh lime juice to marinade and left it for 24 hrs. Followed the recipe further and was mind-blowing. Easiest, tastiest lamb ever! Thank you for the inspiration…
Wow! Thank you, Jennifer!
Where do i get the lamb stock from?
Hi James! Use beef or chicken stock instead. Thanks
I agree with you
I plan on trying this recipe (in the slow cooker) sometime this week. I was wondering if it would work equally well to brown the outside BEFORE adding it to the slow cooker. I was thinking that it might be easier because once it comes out of the slow cooker, if it’s already falling apart that it may be more difficult.
Yes that’s another option. Brown first before adding to the slow cooker.
Just finished eating this recipe! It was amazing, very good flavor. I drizzled a tbsp of apple cider vinegar on top as well. This was a very great lamb meal!! Thank you for this!!
Awesome! So glad it turned out great!
I must admit I haven’t tasted it yet…it marinating. But one point people may wish to know is that unless the package says otherwise, the mesh holding a boneless leg of lamb together can be used to put the roast back together and cook. My package only said to remove the mesh if barbecuing. So much neater and uniform than I could do with string.
Wow! Great Tip Anthony.
My husband made this recipe last week. The only additions he made were to add potatoes and carrots which he placed around the lamb. It was awesome! We will definitely be making this again. Thank you for sharing.
Yaaay! Thank you for letting me know, Linda. And thanks for the tip. 🙂
Just wondering…. won’t putting it in the over for an additional 2-3 hours overcook it? I am interested in how oven cooking changes this…. but don’t want to char my lamb! Thanks.
Hi Samantha. That oven part there is another cooking method that you can follow to cook this lamb leg. SO you either do it slow and low using the slow cooker (with an additional 10 minutes in the oven on broil to achieve that added crisp) OR roast it in the oven for 2-3 hours at 350 degrees F. Hope this clears out the confusion.
THANK you!
Can I suggest you change the wording of this part?
“You can enjoy a tender and juicy lamb leg after it’s cooked in the slow cooker or if you want an exterior crispy and pretty browning, you can pop it in the oven afterwards for an additional 2-3 hours.”
It makes it sound as though you slow cook it THEN roast for 2-3 hours.
Thank you for pointing it out, Hannah. Already edited the post.
Want to try this, but still confused. You EITHER cook in slow cooker, then broil for 10-15 minutes for crispness OR roast in oven for 2-3 hours, right? Hannah’s post appears to say to “pop in oven for 2-3 hours” after slow cooking….That’s incorrect?? . Just want a little clarity….can’t wait to try it.
Hi Pat , Sorry for the confusion. You either cook in the slow cooker , then broil on low heat for about 5-10 minutes rotating the lamb ,half way through- it all depends on your oven. It might take longer time for crispness . Start checking after 5 minutes and use your best Judgement.Or roast in the oven. I have updated the recipe with detailed and clearer instructions for roasting in the oven. Hope this helps.
hi. this is great recipe. i have tried it out it’s really delicious..
thanks for sharing
Awesome! Thanks for taking the time to provide feedback!
Thank you for this delicious recipe. I made it for Thanksgiving and it was so moist, tender and flavorful. There were no leftovers. The only addition I made was that I added Lipton’s beefy onion soup mix to the gravy to give it more flavor. The lamb was absolutely delicious. Also, I did not have twine to tie the lamb and it was no problem I cooked evenly. Thank you again
My pleasure ! Thank you so much for taking the time out to let me know.
May try this for Christmas. Looks delicious! My family love lamb, however, I usually cook it the same… french style with a breading. You may want to reprint because there is an error in your item 6 under instructions. You have “turkey” instead of “lamb”.
Got it ! I have rewritten to make it clearer. Thanks for bring this to my attention
What sides can you have this ?
Hi Kim. You may pair it with any of the following: Scalloped Potatoes, Carrot Souffle, Green Beans, and Mashed Potatoes.
