Ingredients You’ll Need

1 (5- to 6-pound) bone-in leg of lamb, tied with twine: A well-marbled cut is ideal for slow roasting; you can ask your butcher for help.
1 tablespoon kosher salt: Essential for enhancing the natural flavors; adjust if you’re sensitive to salt.
2 teaspoons freshly ground black pepper: For a touch of warmth; pre-ground can work, but fresh is always better.
4 large shallots, peeled and halved lengthwise: Shallots are sweeter than onions, adding a gentle flavor profile.
2 heads garlic, halved: A must for infused flavor as they caramelize beautifully during roasting.
2 lemons, halved: Their acidity cuts through the richness of the lamb and brightens the dish.
8 sprigs fresh thyme: Earthy and aromatic; fresh herbs are highly recommended over dried.
6 sprigs fresh oregano: Adds a lovely Mediterranean touch; opt for fresh, if available.
4 sprigs rosemary: A classic partner for lamb, lending its woody flavor to the meat.
1 (750 mL) bottle dry white wine: Enhances flavor depth; choose a wine you’d enjoy drinking.
1-2 cups low-sodium beef broth, plus more as needed: Use for moisture; low-sodium keeps it healthier.
1/2 cup extra virgin olive oil: Rich in flavor and helps the gremolata adhere to the lamb.
3 tablespoons red wine vinegar: Adds tanginess, balancing out the dish.
2 teaspoons lemon zest: The zest provides a concentrated lemon flavor, enhancing freshness.
1 tablespoon freshly squeezed lemon juice: Brightness in the gremolata; it’s worth using fresh.
1/4 cup minced shallots: Adds a subtle bite in the gremolata.
2 garlic cloves, grated: For a pungent, fresh garlic flavor.
1/2 cup finely chopped fresh cilantro: Refreshing and bright, a unique twist for the gremolata.
1/2 cup finely chopped fresh dill or Italian parsley: Use what you prefer or have on hand.
2 tablespoons drained and rinsed capers: Briny flavor that elevates the gremolata.
1/2 teaspoon kosher salt: Essential for seasoning the gremolata; adjust according to taste.
1 teaspoon Aleppo pepper (or 1/2 teaspoon crushed red pepper flakes): For a gentle heat, without overpowering.

How to Make Slow-Roasted Leg of Lamb with Gremolata

Preheat the Oven: Start by preheating your oven to 350℉. Pat the leg of lamb very dry with paper towels. Season it liberally with 1 tablespoon kosher salt and 2 teaspoons freshly ground black pepper. Feel free to do this step up to 24 hours in advance—just refrigerate the meat uncovered until you’re ready to roast. When you’re ready to cook, let it come to room temperature for about an hour.
Prepare the Dutch Oven: In a large Dutch oven with a tight-fitting lid, layer the bottom with the halved shallots, garlic, and lemon (cut side down), followed by scattering the thyme, oregano, and rosemary. Add the lamb (skin-cap side down) on top, ensuring the thicker part of the meat is at the bottom for even braising. If you don’t have a Dutch oven, a tightly covered roasting pan will do—just be mindful you may need a bit more broth.
Add Liquid and Roast: Pour 1 (750 mL) bottle of dry white wine over the lamb, followed by the low-sodium beef broth, one cup at a time, until the liquid rises 1 to 2 inches up the sides of the meat. Cover the Dutch oven and place it on the middle rack of the oven for 4½ hours. Resist the temptation to open the lid during this time—just set it and forget it!
Check the Lamb: After 4½ hours, check whether the lamb is ready. Poke it with a fork—if it flakes easily, it’s time for the finishing touches. If there’s still some resistance, cover the lamb again and let it roast for an additional 30 minutes. Once it’s tender, carefully flip the lamb over, basting it with the roasting juices, and return it to the oven uncovered. Let it bake for 40 to 45 additional minutes until the surface is deeply browned and crisp.
Let it Rest: Remove the leg from the oven and allow it to rest for 10 to 15 minutes before shredding. This step is important as it lets the juices redistribute throughout the meat.
Make the Gremolata: While the lamb is roasting, mix up the gremolata. In a medium bowl, whisk together 1/2 cup extra virgin olive oil, 3 tablespoons red wine vinegar, 2 teaspoons lemon zest, and 1 tablespoon freshly squeezed lemon juice. Stir in 1/4 cup minced shallots, 2 grated garlic cloves, along with 1/2 cup finely chopped fresh cilantro, and 1/2 cup of finely chopped fresh dill or Italian parsley. Finally, fold in 2 tablespoons of drained and rinsed capers, 1/2 teaspoon kosher salt, and 1 teaspoon Aleppo pepper. Taste and adjust seasoning if it needs a little more zing.
Serve and Enjoy: When the lamb is ready, move it to a cutting board, shred it into medium chunks with two forks, and transfer it to a serving platter. Spoon the gremolata generously over the lamb and serve warm.

Storing & Reheating

For leftovers, allow the lamb to cool to room temperature and store in an airtight container for up to 3 days in the refrigerator. If you’d like to keep it for longer, you can freeze the lamb for up to 3 months—just ensure it’s well-wrapped. When reheating, place it in a 350℉ oven until warmed through, about 20-25 minutes. You may notice minor changes in texture or flavor, but reviving it with a splash of broth will help refresh its natural moisture.

Chef’s Helpful Tips

Avoid the most common mistake of overcooking the lamb. Use a fork to check doneness; it should flake easily.
For the best flavor, always ensure your ingredients (especially the lamb and herbs) are at room temperature before cooking.
If you have extra time, consider marinating the lamb in the seasoning overnight.
When shredding, you can mix in some of the juices from the pot for added flavor.
Feel free to adjust the herbs according to your taste—other herbs like mint or parsley work wonderfully too.
Make the gremolata while the lamb is roasting to let the flavors marry beautifully.

The slow-roasted leg of lamb with gremolata is not just a meal; it’s an experience filled with warmth, flavor, and cherished moments.

Recipe FAQs

Can I use a boneless leg of lamb for this recipe?

Absolutely! A boneless leg of lamb will work beautifully; it may cook slightly faster, so keep an eye on the internal temperature.

How do I know when the lamb is done cooking?

The best method is to use a fork; if it flakes easily, it’s ready. You can also use an instant-read thermometer to check for optimal doneness—145℉ for medium-rare.

Can I make this recipe ahead of time?

Certainly! You can prepare the lamb and refrigerate it overnight before roasting. Just remember to let it come to room temperature before putting it in the oven.

What if I don’t have fresh herbs?

If you don’t have fresh herbs on hand, you can use dried ones as substitutes; however, reduce the amount to about one-third since dried herbs are more concentrated.
