There’s something truly special about a perfectly roasted leg of lamb. It’s rich in flavor, beautifully tender, and just the right balance of savory and herbaceous. Whether you’re preparing it for a holiday feast, a Sunday dinner, or just treating yourself to something extraordinary, this easy roast leg of lamb recipe is sure to impress without requiring too much effort.
The key to a great roast leg of lamb lies in the seasoning. You don’t need a complicated marinade, simple is best here. Start by making a garlic and herb paste with fresh rosemary, thyme, garlic, olive oil, and a pinch of salt and pepper. Rub this mixture all over the lamb, making sure to coat it generously for maximum flavor. The herbs provide an earthy, aromatic base that complements the rich lamb beautifully.
Once seasoned, the lamb is ready for roasting. Place it in a preheated oven at 180°C (350°F) and roast until it reaches your desired level of doneness. For a medium-rare roast, aim for an internal temperature of about 125-130°F (52-54°C), which will continue to rise as it rests. Roasting times generally take about 1.5 to 2 hours, depending on the size of the leg and your preferred doneness.
To achieve a beautifully golden crust, you can sear the lamb in a hot pan for a few minutes before roasting. This step adds extra flavor and a nice caramelized exterior.
Once the lamb is done, allow it to rest for at least 10-15 minutes before carving. This helps the juices redistribute, ensuring each slice is juicy and tender.
Serve your roast leg of lamb with roasted vegetables, mashed potatoes, or a fresh green salad to balance the richness of the meat. A drizzle of mint sauce or a red wine reduction can elevate the flavors further, adding a refreshing and tangy contrast.
This easy roast leg of lamb is perfect for creating memorable meals with minimal fuss – flavorful, impressive, and satisfying every time.

Yummy! The garlic and rosemary combo is delicious. Who knew lamb could be so good??
Easy recipe, but not a fan of lamb. I like chicken better.
Looks too simple. Is it really that easy? I have my doubts…
Is it normal to serve this with ketchup? Asking for a friend. 🤔
just what I needed for my dinner party! Can’t wait to make it! ☀️
I make mine with mint jelly on the side. Y’all should try that! 🙂
I followed the recipe, but my lamb came out a bit tough. Maybe my oven’s temp was off?
Maybe you cooked it too long? Lamb can be tough if overdone. I usually check it with a meat thermometer!
Okay, I gotta say, I tried it and it was…just okay. Nothing too special.
Why does everyone love lamb? I don’t get it, tastes like sheep.. no thanks.
I totally get why you feel that way! Lamb has a strong flavor that not everyone enjoys. But have you tried it cooked with plenty of herbs? It can really balance out the taste!
Easy and tasty!! I like to serve mine with mashed potatoes.
Soo good!!! 🐑💖
I followed the recipe but my lamb was tough. What did I do wrong?
This looks delicious! Can’t wait to try it for the family dinner.
Easy?? Didn’t seem easy when I was swearing in the kitchen! But worth the hassle.
Hmmm… does lamb have to be cooked medium-rare? I thought it was supposed to be well done.
Lamb is so good! I love the garlic and rosemary… yumm! 🤤
Omg, this was so easy and fast! Enough for leftovers too! 😋
Tried this recipe for a special occasion, turned out pretty good! However, I left it in the oven just a bit too long.
Yo, this is too much garlic, next time I’m using half! Still tasty tho.
Nah man, more garlic is better! Just the right kick for lamb!
I love garlic but I get it! It’s a strong flavor. You do you!
This is way too much effort for a piece of meat. Ain’t nobody got time for that. 1 star!
5 stars! I’m not even a cooker but this was easy peasy and my friends were impressed.
I was a bit skeptical at first, but it turned out pretty good. Just wish the lamb was a little more tender.
I never know how to make lamb. This helped a lot! But it took forever to cook.
Simple and easy! The kids loved it!
This recipe was super easy to follow! The lamb turned out juicy and flavorful. Will def make again!
Lamb? Never tried it before. Thought it was too fancy for me. Decided to give it a shot, but it was not great, sorry.
This recipe is a lifesaver! I followed it exactly, and my family loved it. The garlic and rosemary really bring out the flavor.
I don’t have rosemary, can I use dried herbs? Will it still be good?
What’s the deal with the resting time? Sounds like a waste of time. I just carve and serve.
I forgot to buy rosemary and used thyme instead. It still tasted good. Just sayin’!
Eh, it was alright. Nothing special. My grandma used to make lamb better than this when we was little. Maybe I’ll stick to her recipes.
Too much oil for my liking. Would cut back next time.
This leg of lamb was amazing! Juicy and flavorful, my family loved it! Definitely a 5-star meal.
This was super easy and absolutely delicious! My family loved it. Will definitely make again!
Looks good, but isn’t lamb a bit too strong in flavor? I prefer chicken.
Glad to hear it turned out great! This recipe is a winner in my book. 😊
As a pro chef, I can say this is basic at best. Needs more seasoning!
As a home cook, I found the seasoning just right! Sometimes, less is more. Enjoyed it!
Isn’t lamb supposed to be, like, a special meal for holidays? I was just curious why anyone would make it on a regular day? 🤔
I think lamb can be amazing any day! It’s not just for holidays. Just makes it feel fancy! 😊
Easy to follow recipes! My husband said it was the best lamb he ever had, and I believe him! Thanks!
That sounds delicious! I’m gonna try it for my family this weekend. Can’t wait to see their reaction!
Best lamb? Really? I mean, did you use a special recipe or something? Looks pretty standard to me.
This looks absolutely delicious! Can’t wait to make it for Sunday dinner.
Yum! My first time roasting lamb, and it was delicious! I didn’t even know what rosemary was before this!
not sure what internal temp means?? but we cooked it for too long anyway 🙁
This seems a bit bland… I added some lemon juice for extra flavor.
Lemon juice? Really? I feel like the garlic and rosemary should be enough flavor on their own. Guess we all have different taste buds!
Easy and delish! Adding this to my go-to list for holidays. Thanks for sharing!
So glad you liked it! It’s a family favorite for sure. Happy cooking!
Looks good, but isn’t lamb super fatty? I usually avoid it.
I thought it was too garlicky. Maybe I used too much? I wouldn’t make it again, but it looked nice.
Garlic can be strong! Maybe just use 2 cloves next time? It’s really tasty otherwise!
I tried this but ended up overcooking it. How do you get it medium-rare? I think my oven is broken…
I just guess the time, lol. My lamb always turns out good! Try not to overthink it!
It sounds like your oven might be too hot! You can also use a meat thermometer to check the temp before it’s done. Medium-rare is 145°F.
I didn’t like it at all. Lamb is too greasy for me. I prefer chicken. Just my opinion.
I hear ya! Lamb can be pretty fatty. Have you thought about making it with chicken instead? It’s a lot leaner and could be just as tasty.
You don’t know what you’re missing! Lamb’s the best! Chicken is so boring… but hey, to each their own.
Are you serious? My grandma used to make it different with mint jelly. This is not it!
i made this but used thyme instead of rosemary. It was also good, ya know. No biggie!
Where’s the lemon? You gotta add lemon zest or its plain.
Is it really that easy? I don’t trust it. Last time I made lamb, it was a disaster. Not sure I’ll try again.
I think it needs more seasoning. Just salt and pepper ain’t enough, right?
I don’t know, I followed the recipe but it came out too salty for my taste. I might have overdone the salt part. 🙁
Maybe try using less salt next time? Or you could balance it out with something sweet!
I think it’s just the recipe. Everyone has different taste buds, right?
My kids loved it! They said it tasted like a fancy restaurant. Thanks for sharing!
Roasting lamb? Isn’t that a little too fancy? I just don’t think I can pull it off.
Don’t worry! This recipe is super easy. If you follow the steps, you’ll do great! Just take your time.
Fancy or not, it’s just meat! My mom used to just throw it in the oven. You got this!
Gonna try this with some BBQ sauce! Bet it’ll taste bomb.
BBQ sauce? That’s a bold move! Can’t wait to see how it turns out!
My kids didn’t like it. They prefer chicken. But I thought it was great!
How long should I let it rest? It doesn’t say in the instructions!!
I followed this recipe for Easter dinner and it was a hit! Perfectly juicy! 👍
This was the best leg of lamb I ever made! So juicy and flavorful. The garlic and rosemary combo is simply divine! Will make it again for sure!
So easy!!! I was worried it would be hard, but this recipe is straightforward. I’m not a pro at cooking so I really appreciated the simple instructions!
For the garlic and rosemary you can use dried ones too. Might not be as good tho.
Followed the recipe, and it was a hit! Juicy and full of flavor. Definitely will make again.
Is it really that simple? I was skeptical, but the lamb was juicy and flavorful. Bravo!
Yes! It’s super easy, right? I made it last week and my family loved it. Can’t believe something so simple can taste so amazing!
Garlic and rosemary is a classic combo! This turned out better than I expected. Yum!
It was okay but I’ve had better at restaurants. Not sure if I’d make it again.
I totally disagree! This recipe is classic and delicious. Maybe you just need to tweak your seasoning a bit?
