If you haven’t cooked a leg of lamb before, don’t be intimidated.

I know, it seems incredibly daunting but it’s so much easier than you think. It’s fool-proof and fuss-free. And you don’t even need a long drawn-out ingredient list.

Nope, the ingredient list is super simple here – all you need is garlic, olive oil, fresh herbs, Dijon, salt and pepper.

Now I left the shank on for it’s dramatic presentation but you can easily purchase one with the shank removed – there’s no advantage here except for the aesthetic eye for serving.

Marinating is also not needed here – you’ll see that the simple garlic mixture of this recipe will bring in so much flavor. And it’s sure to be a crowd-please for your Easter holiday or your next dinner party. It also pairs perfectly with these mini hasselback potatoes!

Roasted Leg of Lamb

This recipe is so good yet it doesn’t require too much time, effort or ingredients. It’s easy & fool-proof, even for you first-timers!

20 minutes1 hour 45 minutes


  • 1 (5 to 6 pound) trimmed bone-in leg of lamb

  4. Place lamb, fat side up, on a rack in the prepared roasting pan. Spread garlic mixture evenly over the lamb, rubbing in thoroughly into the scored cuts.

    This is a fantastic recipe. I tried it twice; the first on a three-year-old Icelandic ewe and the second on a yearling lamb. The latter was a LOT smaller than commercial breeds, so I eased back on the time by about 30 minutes-ish, using the thermometer of course.

    I plan on trying the recipe on venison this season because why the hell not?

    Ok, I consider myself a lamb expert. Aussies know how to cook lamb, we are raised on it. This recipe is basically identical to the one we use for roasts, but, minus the thyme. I grow thyme in my garden, so it was easy. Great addition, thank you!

  3. Rated 5 out of 5

    I’ve been cooking lamb all my life but never used chopped thyme,but just the addition of the thyme took the lamb to a higher level if was simply delicious,I’ll certainly use this rub again.Thankyou for sharing this recipe.

    Sounds Amazing.  Planning to make tonight.  
    Question? Can you taste the mustard when you eat the lamb?  My kids don’t like mustard.  

  7. About to make this. Can I omit the rosemary? My family hates the taste.

    Super duper roasted leg of lamb.   , delicious, wonderful left overs for another dinner of yummy roast lamb. Or, Enough for  a hearty lamb stew or yummy spicy lamb curry . Finally boil the bones , add  any bits of chopped lamb,  chopped vegetables and left over gravy.  Finely grate a raw potato into soup and simmer if a thicker soup is desired .   Cheers and enjoy.

    Tried this recipe for a family dinner and it was a hit! Even my cousin who doesn’t care for lamb complimented the great flavor. The prep is easy and in most cases these are ingredients we already have at home, love the practicality. I have also used this on fresh pork ham with great results. Thanks for posting!

    I have never left a review before but I just had to today. Leg of lamb is my husband’s all time favourite. He loved this recipe. I am not a lamb fan, but when I cook it I always try it to make sure it is seasoned correctly. It was very juicy and I loved the seasoning. I gave it the 5 stars because my husband is still talking about it. I will definitely be making this for him and guests again.

    Thank you for this amazing recipe. This was so good I just had to comment. I used dried basil instead of thyme as that was what I had on hand, ginger powder instead of garlic and added a bit of dried mint and marinated overnight. I roasted it for 2 hours as it still had a little blood after an hour and half. Loved that this was so  simple yet so good. Our family roast recipes generally involve heaps of nuts which I can’t use because of food allergies so this recipe was a godsend. Highly recommend!! 

  15. Was my first time to make leg of lamb – was so easy and beyond delicious!! Best ever – in my recipe book

    Super easy, 5.6 lb boneless leg came out perfect after 1.5 hrs. Thanks! I decided to serve it with the potatoes, steamed Swiss chard and a tiny dollop of horseradish or Dijon too

    • Oooo I see now that it says 1 tbsp of salt. I only used a tsp. Still game out great!!!

    • I’ve never cooked lamb in my life….  do I need to ask the butcher to do anything special when prepping the leg? 

      Can I take the juices from the lamb and make some sort of gravy…. how do I do this?   Please be specific… again never cooked lamb before

      What temp should a leg of lamb be when cooked (is it best med rare?) 

      Thank you for your help! 

      This looks amazing and I can’t wait to try it….

    I tried it… I loved it! I made it last night!!!!!
    I used ground thyme instead of fresh, I also lowered the amount of it to 1/4 t. ( Because it would have been too overpowering) Other than that I followed the recipe exactly as given. I appreciated not needing to marinate it before putting it in the oven. After taking it out of the oven and letting it sit for 15 minutes,I sliced off a few pieces and shared some with my daughter. It was delicious!!!! Even though it was late (after 10 pm) I found myself stealing little slivers. If you’re wondering which recipe to try, look no further.

  20. Hi,
    In defence of poor Carol who asked an innocent question . The recipe for potatoes that you shared link to, gave the 425 temperature 😉
    Recipe looks great. Will try not to mess with it!

  21. Rated 4 out of 5

    Absolutely delicious!! It was a big leg of lamb, I’ve cut two onions and lots of garlic + thyme and rosemary and a good splash of red wine! Then  I’ve put the oven at 160 degrees Celsius, gas mark 3 or 320 Fahrenheit for 4 hour covered with foil then last hour removed it, it was nice and soft, juice meat, delicious!! The juices left to make the gravy it’s to beautiful to mix it with flour…I’ve just used the blender, And smells ridiculously good everywhere in the house!!Beautiful wish I could post the picture

    • So, you DIDN’T make the recipe. Right? No Onions! Not with Lamb and not called for. 4 hours??? Did you make Lamb Jerky? smh

  22. I haven’t made this yet but plan to tomorrow. How do you cook the lamb at 350 degrees and the potatoes at 425 degrees at the same time in the same oven.
    Thanks so much. The recipe sounds delicious.
    Thanks, carol

    • Hi. Where does it say 425 degrees? If you don’t have one of those fancy ovens that can cook at two different temperatures, make the at 350 degrees. Will come out fine.

    Just made this last night. First time cooking lamb and second time ever having lamb (first time I did not like it). This recipe was amazing, I made a couple of slight modifications by adding smoked paprika, lime basil, and fresh mint leaves to the rub. I knew this was going to turn out well as soon as rubbed the marinade all over the lamb (it smelled absolutely divine). I also made the hasselback potatoes with sweet potatoes to go along with it (definitely worth making). This had the feel of a super upscale dinner. Definitely a meal you could cook if you are trying to impress someone, would definitely use this recipe again. Absolutely delicious.

  33. The Best! I have cooked lamb several times over the years but this it the absolute Best recipe and the potatoes were great too!

    made this yesterday afternoon. Was just going to make a simple roast, then I found this recipe and since everything I have made from Damn Delicious has been damn delicious I had to try. I was not disappointed and neither were those that ate with me. I did not make the potatoes as I did not have, but did make roasted asparagus and that too was great.
    Thank you for another great recipe.

    Perfect! This was the first time I’ve ever cooked leg of lamb, and it was amazing!! There are 9 in our household from ages 11 to 76, and ALL of them thought it was delicious. The recipe did NOT require a dozen ingredients that I will never use again, the instructions were easy to follow, and it worked. I will definitely be keeping this one and making it again; it will be our family’s Easter dinner from now on.

  44. The bone provides a lot of flavor as does skin. Hence the term soup bones.

    We raise lamb and it is typically too gamey for me. THIS, however, was phenomenal!!! Everyone raved. Seasoning, tenderness, flavor…best lamb we’ve ever had. Be sure to let it rest while covered. Will use this for many more Passover’s to come! THANK YOU!

  49. Rated 5 out of 5

    This was SO GOOD! We’ve never cooked lamb before. I prepped it exactly per the recipe, but then my husband put it on the kamado grill, indirect heat, at 350. The leg was 3.4 lbs and took an hour to reach 140. It was amazing. Thanks for another awesome recipe!

  50. It was good but I think we made the cuts in the fat too deep.  Is that possible?  It was quite salty, leaving me to think that it should be 1 teapoon of salt, not tablespoon?  When you say shallow cuts, how deep?

  51. My boyfriend liked it so much when I made it that I thought he was just about to propose, lol. This is the best recipe I made for lamb, simple and soooo delicious. Making it again for this coming Easter.

    I altered the recipe a bit since I didn’t have dijon mustard – I just used a maple mustard hot sauce I had, with rosemary mixed in, and I had pre-salted the lamb so I didn’t mix salt in with the sauce. My roast was 4.5 pounds (bone-in) and was cooked perfectly in a little over an hour. So easy!

  61. Rated 4 out of 5

    Well my family does love a crunchy skin but just wondering if wrapping and cooking it in tinfoil for the first hour helps make it more tender / cook more evenly? 

  62. So delicious, easy to make. I often get excited about cooking new recipies that turn out to be mediocre plates since I think I’m not a good cook. I was so pleased with this one. Came out sooo goood

  63. It was so delicious, especially the flavourful crusty skin. My kids and significant others gobbled it up! I served it with mint jelly and Greek Leon roasted potatoes.
    I did substitute  orange-lime infused sea salt for the regular sea salt. I actually didn’t check the recommended temperature and didn’t take it out of the oven until it reached 157F and it was still super tender and moist.
    Can’t wait to make it again since it was so easy and a big hit.

  64. Rated 5 out of 5

    The flavor was amazing!! I also added some balsamic vinegar to the rub mix and I let the roast be marinated overnight. Even those who typically are averse to lamb even enjoyed this dish tonight! It was one of the easiest recipes to make!

  65. Leg of lamb cooked with bone in, is Far better than boneless. bone adds to flavour, as with any meat. and cooked long and slow makes it literally fall off the bone with great flavour.

    This was AMAZING! A truly easy–no, make that IDIOT PROOF–recipe. The rub made all the difference in the world. I had my doubts about a garlic and mustard rub but OMG it makes the lamb POP! I scored the top (fatty side) of the roast for the rub; next time I’ll try doubling the rub so I can score all around the roast.

      This was delicious! I changed a few things around because I didn’t have the exact ingredients. I used boneless lamb, regular yellow mustard, ground thyme, regular salt and no rosemary and it still came out amazing. I was a little scared because I didn’t have the exact stuff but surprisingly it was awesome. Thank you for this reciepe!!!

    Used 5.5# of bone-in lamb. Followed instruction until step 3 as I had some left over chimichura in the fridge … used that as base and added fresh rosemary & thyme to my blend. From there, followed as instructed — and it was great! The cooking times were spot on (thank you!!). I will bookmark this method and share with our dinner guests who raved!

    I prepared this awesome recipe down here – Brazil. It’s easy to follow it although it isn’t easy to find Kosher salt, but in a recently travel to Israel my girlfriend brought some. I needed to use dried thyme because I hadn’t the fresh one.

    This was amazing!! I will be keeping this receipe for every time I make leg of lamb! I did however use dried rosemary and thyme (little more than a teaspoon) rather than fresh because thats what I had in the house. It was amazing!

    Delicious and easy. I should have spent more time rubbing the spice mix in the cuts more thoroughly for even better flavor. I had a 6 lb boneless leg of lamb and I cooked it for 1 hour 30 minutes (family doesn’t like the meat pink).

    Loved the recipe with the rub but I still recommend putting slits in the meat and stuffing it with slivers of garlic for that awesome taste throughout. TY

    Hi Chungah
    You are right : first time yesterday and it was sooooo goooood☺…damn delicious.. I almost regretted why I didn’t buy a bigger leg to be enough for my guests. thank you

  88. Hi!! 
    Did you cook the potatoes with the lamb? I’m looking at both the recipes and they cook at different temperatures and for different lengths of time. I really want to try this, but I’m just not sure abou the temp/time. 

    • Yes, they were both cooked at the same time in a double oven but you can still cook multiple dishes in one oven! Here are some helpful tips:

      Most ovens have a 25-degree variance. If one dish needs to be cooked at 350 degrees F and another at 400 degrees F, set the oven for 375. Most ovens are off by about 25 degrees anyway so as long as it’s set around the required temperature, the dish will turn out fine.

      But please be sure to arrange the dishes so there is enough space between them. Air should be able to circulate between all the dishes.

  89. So perfect for Easter! This lamb looks so delicious!

Thank you!!! New follower on your IG, new subscriber as well. Simple instructions, yet an amazing Sunday roast meal. Thanks again!

  94. …the French version of leg of lamb is even easier…..the French call it “weeping leg of lamb”……
    ….garlic rub;one slice of bacon; foundation of thinned sliced russet potatoes…peeled or not….
    …can also be made with roast of pork….
    …..any version of apples goes well for dessert…..w/a good cheese!

    however, this version of leg of lamb also looks very tasty!
