Mary Heffernan of 5 Marys Farms recently sent me the MOST special package of cuts from her family’s farm! Included, was a bone-in lamb leg. I hadn’t cooked lamb before and wanted to make sure that my recipe was well-researched, thought-out, and deserving of such a special cut of meat. After our research, I settled on a Greek-style, slow-roasted leg of lamb. The end product was nothing short of totally epic, y’all.
Here’s how it starts: pierce your leg of lamb so that you can slide 20 pieces of garlic (10 cloves, cut in half length-wise) inside. Roast at high heat for a bit, then lower heat for about 3 hours. A mixture of white wine, lemon juice, broth, and fresh herbs are added in at strategic times. This method yielded the MOST DELICIOUS lamb I have ever, ever enjoyed.
Slow Roasted Leg of Lamb Ingredients
The ingredient list is fairly simple here. Here’s what you’ll need:
- Bone-in Lamb Leg Roast – to start, you’ll need to grab 1 (5-6 pound) bone-in lamb leg roast.
- Garlic Cloves – 10 cloves garlic (sliced in half) really infuses such a delicious flavor into the lamb.
- Olive Oil – 2 tablespoons of olive oil helps to brown the outside of the lamb just a tad.
- Sea Salt + Pepper – to season the lamb roast, you’ll need 1 tablespoon of sea salt + a ½ teaspoon of pepper.
- Fresh Herbs – 4 sprigs of fresh rosemary, 4 sprigs of fresh oregano, and 4 sprigs of fresh thyme add the most delicious, herby flavor here.
- Lemon Juice – a ½ cup (8 tablespoons) of lemon juice adds a touch of acidity and brightness. We recommend going with fresh lemon juice, so you’ll need about 4 whole lemon’s-worth of juice.
- White Wine – you’ll also want to grab 1 cup of white wine. If you’d prefer to omit the wine, simply swap in an additional ½ cup of lemon juice and ½ cup of chicken broth in its place.
- Chicken Broth – lastly, you’ll need 1 cup of chicken broth!
How to Make Slow Roasted Leg of Lamb
This slow roasted leg of lamb recipe is really simple but makes for a dinner that is sure to impress. Here’s how you’ll pull it off:
- Preheat the oven to 450°F.
- Prepare the lamb roast – make 20 slits in the skin of the lamb roast, insert the garlic clove halves into the slits, then rub the leg with the olive oil, and liberally season it with salt and pepper.
- Bake – place the roast in a large, heavy-bottomed pot with a lid and bake uncovered at 450°F for 30 minutes, fat-side up.
- Add the rest of the ingredients and bake – add the thyme, rosemary, oregano, lemon juice, wine, and broth, then cover and bake at 350°F for 3 hours. Check toward the end to make sure that the liquids haven’t all dried up. If they have, add more broth as needed.
- Remove lid and bake – remove the lid, and bake for additional 30 minutes at 350°F or until the top of the lamb roast is browned. If liquid has dried, add more broth.
- Serve – serve with additional lemons, skim pan juices for the sauce (skimming off fat) and season to taste with additional salt, pepper, and lemon juice.
What to Serve with Roasted Lamb
This slow-roasted leg of lamb is absolutely delicious alongside mashed potatoes or roasted hasselback potatoes or this creamy mushroom risotto. Add a simple arugula and lemon salad and you’ve got a complete, really delicious meal!
Frequently Asked Questions
We prefer to do a combination of covered and uncovered baking so that the outside of the lamb can get nice and browned while the inside stays super tender and juicy.
We start our lamb at 450°F to help it brown, then lower the temperature to 350°F after about 30 minutes to help it get more tender.
We do a combination of covered and uncovered cooking here – about an hour total (30 minutes at the beginning and 30 minutes at the end) of uncovered cooking time and 3 hours of covered cooking time.
Sure! I would recommend searing it for 3-4 minutes per side over medium-high heat in a heavy-bottomed pan first, then transferring to the slow cooker. The lamb would take 4-6 hours on high or 8 hours on low in the slow cooker.

If my lamb is only 2.56 lbs, should I just decrease cooking time?
Is right side up fat side up?
Yes, that’s correct! I’ll make that more clear in the instructions now!
Made it with leg of lamb fir my neighbour and she loved it! Today I am making it with a lamb shoulder – hope it will be as tender and tasty as my prior attempt!
Wahoo! So glad it was a hit!
Hi there,
Just wanted to say thank you for this recipe! It is a taste sensation and is now the only way I do lamb! Thanks again
Wahoo! So glad you love it, Danny!
So I got everything ready and found I don’t have white wine, will just chicken broth be ok?
Yes, totally fine, Barbara!
I have a 3 pound leg of lamb with bone in. How long should I cook. Lower bone section removed.
I’d cook it for 2-2.5 hours (rather than 3), until the internal temperature reaches 130°F for medium doneness. Enjoy!
Super tasty & easy to make!
So glad you enjoyed this, Monique!
Could you use a boneless lamb here? Also, do you think dry herbs would work at all? Thank you!
Yes to both, Emily! Enjoy!!
Your directions say to use a heavy pot with a cover but to cook uncovered. but down further it says to uncover, so I’m assuming we are to cover in the beginning, correct?
Hi Jim, it starts out uncovered, but in Step 4 we give instructions to cover it!
One of the best recipes I’ve tried on pinterest.
I have made this recipe every week for the last 6 weeks. Cannot get enough of it! The only difference is after browning it in the oven I pop it in the slow-cooker. I have also used lamb shoulder which is super tender and delicious. I love the zest that the lemon brings. Thanks for the recipe.
How long did you give it in the slow cooker?
It looks like this was a boneless leg, is that right?
It is bone-in!
This roasted leg of lamb sounds absolutely delicious, I love all the fresh herbs that you used in this recipe…impressive
