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 cloves garlic, minced
  • 1 tablespoon olive oil
  • 1 tablespoon chopped fresh rosemary

  •  1 tablespoon Dijon mustard
  • 1 tablespoon kosher salt
  • 2 teaspoons ground black pepper


  1. Preheat oven to 350 degrees F. Line a roasting pan with aluminum foil.
  2. Pat lamb dry with paper towels. Using a sharp knife, score the top side of the lamb by making shallow cuts all over.
  3. In a small bowl, combine garlic, olive oil, rosemary, thyme, Dijon, salt and pepper.
  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.
  5. Place into oven and roast until it reaches an internal temperature of 135 degrees F for medium, about 1 hour 30 minutes to 1 hour 45 minutes, or until desired doneness. Let rest 15 minutes before slicing.
  6. Serve immediately with mini hasselback potatoes.

    Made this recipe and added some chicken broth for basting – it came out moist and very favorable , my dinner went so well , that my guests took second portions , I rate this 5 stars 

  5. Rated 5 out of 5

    This is such a simple, fast, delicious recipe. I have cooked lamb every way imaginable and have never gotten such consistently excellent results. Thank you so much for sharing.

  6. Making for the second time…
    I have a roasting pan with a lid… Do I start covered then remove? Or vice versa? Or no cover at all?

  7. 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? 

  8. 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

  9. 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.

    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!

  11. 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.

    Made this leg of lamb today for New Years Day and it was absolute perfection!  Thank you!

    This was a “hit” with family and friends.   Is so easy to make, except I seasoned it overnight and seared it before putting it in the oven.  Thank you.

  14. Can you make this in an instant pot?

  15. Rated 5 out of 5

    Made this for dinner tonight for Christmas, it came out amazing!! Was very nervous because I never cooked lamb before. It came out perfect. The only thing I did do before cooking, I soaked the lamb in milk the day before. 

  16. Delicious! Just made a lamb roast for dinner tonight and it turned out great. I put 1 beer and cup of Chardonnay as my liquid in a covered roasting pan with add’l sprigs of rosemary and thyme. Tender and yum, yum good. Thank you for the recipe!

    Thank you so much for sharing this recipe. We made it last night and it was delicious! 

  18. Rated 5 out of 5

    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.

  19. How long would you cook this with a 2.5-3 lb bone-in roast?

  20. Rated 5 out of 5

    Oh holy hell that is deeeelicious!! Easy peasy recipe . Thanks for sharing cuz it could have been a disaster!!

    We made this fabulous recipe leg of lamb today. It came out perfect. Thank you 

  22. Rated 5 out of 5

    It looks great and seems easy, however, can i make this ahead of time? I would like to make it the day before thxgiving and then warm it up when my turkey is ready! Would that work? 
    I also have two legs of lamb both bone in, I am guessing that it will need longer, right?

      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!!!

  23. Rated 5 out of 5

    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.
    Definitely I recommend this recipe.

  25. What if I don’t have a roasting pan, what can I use?

  26. Rated 5 out of 5

    Delicious Lamb roast. I decided to try your recipe to roast my 5 1/2 # leg of lamb bone in. Followed the recipe except I

    used dried thyme and rosemary since I did not have fresh. I roasted it for 1 hour 45 minutes .It was pink and perfect. I will use this recipe every time I have lamb.

  27. Rated 5 out of 5

    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!

  28. Hi. I’m not a mustard fan. Can substitute mayonnaise or something else? Maybe just olive oil? Thanks!

  29. Hi, can I roast the lamb leg in an iron pot covered with  iron lid or it has to be not covered 

  30. Rated 4 out of 5

    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).

  31. Rated 5 out of 5

    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

  32. Question, I have a boneless leg of lamb.  Could I cook it the same way?  Cooking time?

  33. Rated 5 out of 5

    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

  34. 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.

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

  36. Rated 5 out of 5

    Anxious to cook though I might use slightly cook rice in the bottom of the pan to absorb all the delicious drippings.

  37. Wow, that lamb looks incredible! Goes perfectly with those Hasselback potatoes (:

  38. Um, how did you know we just bought this exact weight of bone-in leg of lamb for Easter and it’ll my first time making lamb? haha! Crazy! The universe has basically just delivered me the perfect recipe! Can’t wait to try it! 🙂

  39. Girl you were reading my mind! I am a novice who wants lamb for Easter! You never let me down! 

  40. …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!

  41. Any idea how long to cook a 5-6 lb. lamb with the bone out?
