We tried grilling two legs of lamb for a family Easter dinner for the first time and they turned out perfectly! What a special treat… the family loved the lamb! We were a bit nervous about trying a new recipe for the first time for a family dinner, but the detailed instructions were spot on, as always. We cooked the lamb on a Big Green Egg seared the lamb on high heat ~450 degrees, then turned down the Egg to about 325 degrees. Excellent tip on using the skewers to hold the meat together as it cooked more evenly. We served the lamb with a beautifully bright green mint/mango based chutney…. so good!
Im making this recipe tonight for myself but I only have a half pound piece of butterflied lamb leg. i wanted to roast it in the oven but cant find how long should i let cook. any advice?
Hello Naya, it’s only a half a pound? I would sear it on all sides on the stovetop and then put it in a 350°F oven for 10 minutes or until the internal temp is 125°F to 130°F.
This recipe (with your Mint Chimichurri) was a huge hit at our Easter dinner last night. Thank you SO much for the detailed instructions on grilling~my hubby was nervous to attempt (& potentially mess up) such a large, expensive cut of meat but it turned out beautifully. Such a blessing for us as nervous hosts of our first Easter lamb meal
THANK YOU SO MUCH FOR THIS RECIPE GUIDE!! I followed this exactly and my first leg of lamb for this thanksgiving turned out AMAZING!!!
I think I have too many years experience both cooking lamb roasts and eating roast lamb all across France (nothing to compare with the salt marsh raised lamb from the western coast of France, especially near St. Michel). I guess this might be the only advantage of ahem, aging! But I would never cook a roast or grilled leg of lamb without trimming the fat and most of the fell away.
Also it should be noted that marinades might add flavor but they do not “tenderize” lamb. Good pink lamb comes already as tender as it’s ever going to be (go to a quality butcher or market). And only the cook can take that away, ending up with over-cooked dry and chewy lamb.
Lamb fat does not have a good and so it won’t add a good flavor. The opposite might be more true.) The flavor of the lamb roast should come from the lovely pink tender flavor of the meat itself and so even flare-ups are better saved for beef.
My boneless leg of lamb is very thick on one side and thin on the other. Should I cook for short side med rare and cut that part off, grilling the thicker side more? I could also flatten the thicker side before cooking.
Or just make sure the thin side is well on the cooler side of the grill.
Hi — this looks amazing and I’m planning on making this tonight. Other recipes I’ve seen have called for making small cuts in the lamb with a paring knife before marinating. Sounds good, but also like it might allow the meat to dry out? Any thoughts on that? It goes without saying, love the site, have eaten my way through half of it already, and am looking forward to the rest. :)
I haven’t tried this with lamb, but with pork or beef roasts we make small cuts and insert garlic cloves into the cuts. Turns out beautifully. ~Elise
As an English woman, I was raised on the most wonderful lamb; roasted lamb, stewed lamb, braised lamb … you name it! I do take issue over your statement that lamb shoud not be cooked more than medium rare, though. If cooked gently it can be well done without being dry and/or tough. I prefer my meat well done and would certainly not put up with dry, unappetizing meat. “Well done” when “done well” means using patience.
Yummy. The best lamb recipe ever! This is our family’s “go to” recipe. We have shared it many times with friends and family. Thanks for sharing! I just might make one this weekend!
This recipe sounds great! I bought a boneless leg of lamb on sale this week, and am going to cook it this way over charcoal this weekend.
One bit of advice for others who, like me, do not care for really sweet foods, and have therefore ruled out the mint jelly – try a vinegar-based mint sauce instead. Crosse & Blackwell makes one that is readily available in most supermarkets – and I’m sure there are several recipes available if you’d rather make your own. What I like about the mint sauce over the jelly is that you get the wonderful mint flavor added to your lamb without the (in my opinion, anyway) overwhelming sweetness of the jelly. Experiment with it by keeping the mint sauce separate, and just sprinkling some on a fork-full of lamb to see what you think of it. If you do, I’m pretty sure you’ll find yourself happily sprinkling the rest of the lamb on your plate with the mint sauce.
Have a great Labor Day weekend, everybody!
That’s great advice, thanks Nancy! ~Elise
Just made our favorite grilled butterflied leg of lamb yesterday. Recipe: 4-5 pound boneless leg of lamb; marinade: 3/4 cup soy sauce, 1 cup red wine, 1 tablespoon cracked black pepper, 2 tablespoons chopped fresh rosemary, 1/2 cup chopped fresh mint, 4 large cloves garlic, minced. Mix marinade ingredients and pour over opened and flattend leg of lamb in 9×13 inch glass pan or very large zip lock bag, marinate 2-6 hours, turning over several times.Grill over indirect medium high heat. I place lamb over center burner of three burner gas grill, middle burner off. Grill 20-25 minutes each side for medium rare. Let meat rest about 10-15 minutes before slicing. Delicious, always a big hit!!
KristinHow can I print Pam’s instructions?Thank you!!
Hi Kristin, when you go to print the recipe (using one of the print buttons on the page) you can check a box that says “print select comments”, then scroll down to the comment you like and click on it. When you go to print you will print out the main recipe and the comment. OR, you can copy and paste the comment into an email and print it from there.
Very good. Next time I will add a little bit more vinegar and salt. Thanks for sharing.
This looks delicious, So far my favourite lamb as been a slow cooked one with classic rosemary, garlic and ginger but smothered in mint jelly and cooked on high for a while at the end of cooking. I think I’m going to do it this way next time though.
To the person who asked if it may be cooked in an oven because they don’t have a grill. I myself live in an apartment building and unfortunately do not have yard space for a grill. But I absolutely love a leg of lamb so the answer is yes. I dice up a garlic clove. I cut slices in the roast and shove the bits of garlic in the slices before cooking. Scatter your slice depth, some quarter way through and some deeper and some more shallow. You do not want the garlic all concentrated in one section of the roast. I do it all the way around. Heat oven to 350 degrees. Cook fat side up for about 40 minutes. Size of roast varies cooking time so check after about 30 mins. I absolutely agree though that lamb can not be cooked more then medium rare.
We had the grilled lamb last night with the fingerling potatoes you posted recently. I marinated the leg of lamb overnight and added red wine from an opened bottle until the leg was completely covered with the wine and marinade sealed in a gallon size bag. The potatoes along with fresh sliced tomatoes and home made biscuits.
These two recipes may become weekly meals. So easy, so delicious.
How very grateful we are to you for sharing so many wonderful recipes. Almost daily I use one of your recipes. I printed so many of yours and some others that I need to organize them in a binder or something. Any ideas?
Some roasted fennel, or eggplant and a white bean salad with some olive oil and shallots or red onion, would be in keeping with this grilled lamb. Or, in the winter, some potatoes, scalloped, of course.
The only way I’ll eat it is to make a paste of a coarse ground mustard like Grey Poupon, mixed with fresh thyme,rosemary, oregano, garlic, salt and pepper etc or what ever herbs and spices you prefer. I cover the inside of the butterflied roast with this mixture. Roll it up and tie it. If I have any of the mustard mixture left, I brush some on the outside before I sear on a grill over high heat and then finish over med heat until med-rare. Oh and I never trim the fat.
Hi, I don’t have a grill. Can I cook this in the oven instead?
I’ve made leg of lamb on the grill like this for year, but I have always taken as much fat off as I could. I’m going to try it this way next time. I don’t mind the mint jelly eaters and sometimes use the rosemary garlic combination, but sometimes I make it Moroccan style with a cumin/coriander seed rub and harissa and yogurt with cucumbers on the side (though I do put mint in with the yogurt).
Without the fat, it will come out tasting like a shoe. My mom taught me that one.
This looks so good.
Yes! I, too, have learned the hard way to leave the fat on! I just did that recently with a roast leg of lamb – I didn’t trim a thing, and my husband said it was one of the best grilled legs of lamb he’s ever had.
It does seem that you are getting good use out of your new grill!
The crunchy goodness on the outside is referred to in BBQ circles as ‘Bark’. Getting between a BBQer and Bark results in a similar issue of getting between Momma bear and her cubs.
Fat (in BBQ) is GOOD. It makes things self-baste which results in the juicy result. And, since it renders out in the cooking process you don’t have to feel quilty about it. You probably noticed that the resulting roast was not too fatty.
Flare ups from the fat hitting the coals can be a problem though if it stirs up ash which can then contaminate the product. After your initial sear you can always try putting the roast over a drip pan to solve this issue.
Great job. I now can’t wait until lunch (teaches me to check my food blogs out this early in the morning).

Wow, this looks great!!!
I usually just pan-sear lamb in a pan hot and fast then finish it with a blast in the oven. Same concept really.
I actually am one of the mint-despisers, usually just enjoying the flavor of the meat. I do prepare it with herbs which are usually rosemary or thyme with garlic though.
