- 4 Garlic cloves (Peeled): Imparts a pungent, savory depth that marries perfectly with the lamb.
- 2 Lemons (Zest only): Zesty brightness to awaken the palate and add a citrus twist.

How to Make Roast Leg of Lamb with Garlic & Herbs Recipe
Step 1: Preheat Your Oven
Start by heating your oven to 180°C fan/200°C/400°F/Gas Mark 6. This temperature will give the lamb a lovely initial sear, locking in juices for that perfectly roasted crust.
Step 2: Prepare the Herb and Garlic Paste
Pop the fresh mint, rosemary, parsley, garlic, lemon zest, olive oil, and a generous pinch of salt and pepper into a blender or food processor. Blitz everything together until a smooth, fragrant paste forms. If the mixture seems too thick, just add a splash more olive oil to make it easy to spread.
Step 3: Score and Season the Lamb
Take your leg of lamb out and give it a good weighing so you can plan the cooking time precisely. Using a sharp knife, carefully make small incisions all over the lamb. This step allows the herb paste to seep deep into the meat for maximum flavor infusion.
Step 4: Rub on the Herb Paste
Generously coat the entire lamb leg with your freshly made herb and garlic paste, making sure to push some into the small cuts you made. This not only flavors the surface but also keeps the meat tender and moist during roasting.
Step 5: Initial Roasting
Place the lamb in a baking tray and pop it into the preheated oven. Roast for 20 minutes at the higher heat to create a flavorful crust. This upfront heat is what gives the lamb that irresistible golden exterior.
Step 6: Lower the Heat and Continue Roasting
After 20 minutes, reduce your oven to 160°C fan/180°C/350°F/Gas Mark 4. From here, roast the lamb for an additional 15-22 minutes per 500g depending on your preferred doneness. Keep in mind, for medium-rare, aim for the lower end of that range. Remember to let your lamb rest for at least 15 minutes after roasting to lock in the juices and relax the meat fibers.
How to Serve Roast Leg of Lamb with Garlic & Herbs Recipe
Garnishes
Sprinkle fresh chopped parsley or mint leaves over the top to add a vibrant pop of color and fresh herbal aroma. A few lemon wedges on the side also make a lovely garnish and allow guests to add an extra squeeze of citrus.
Side Dishes
This roast pairs wonderfully with roasted new potatoes drizzled with rosemary, a crisp green salad, or even a rich, velvety lamb gravy made from the pan drippings. Steamed seasonal vegetables such as green beans or asparagus add crunch and color to your plate.
Creative Ways to Present
For a stunning presentation, carve the lamb into thick slices and serve it on a large wooden board garnished with fresh herbs and lemon slices. You can also elevate your feast by placing it over a bed of crispy roasted garlic potatoes or scatter toasted pine nuts and pomegranate seeds around for a festive touch.
Make Ahead and Storage
Storing Leftovers
If you have leftovers, wrap them tightly in cling film or place in an airtight container and refrigerate for up to 3 days. The flavors actually deepen after a day, making for even tastier sandwiches or salads later on.
Freezing
The cooked lamb freezes well. Slice or chunk the meat before freezing in a freezer-safe container or bag for up to 2 months. Thaw overnight in the fridge for easy reheating.
Reheating
To reheat, warm gently in a low oven or on the stovetop with a splash of stock or water to keep the lamb moist. Avoid high heat which can dry out the meat. Alternatively, pop slices in a covered microwave-safe dish and heat at medium power in short bursts, checking frequently.
FAQs
Can I use boneless leg of lamb for this recipe?
Absolutely! While bone-in gives extra flavor and juiciness, a boneless leg of lamb will work as long as you adjust the cooking time slightly and keep an eye on the internal temperature to avoid overcooking.
How do I know when the lamb is cooked perfectly?
Using a meat thermometer is the best way. Aim for 60°C (140°F) for medium-rare or up to 70°C (160°F) for well done. Remember to rest the meat after roasting; it’ll continue to cook a bit internally.
Can I prepare the herb paste ahead of time?
You can! Make the herb and garlic paste a few hours or even a day before and store it covered in the fridge. Bring it back to room temperature before rubbing on the lamb for easy prep.
What if I don’t have fresh herbs?
Fresh herbs provide the best flavor, but you can substitute dried herbs in smaller amounts. Use about one-third the amount of dried herbs and add them directly into the olive oil to rehydrate before mixing into the paste.
Is this recipe suitable for a special occasion?
Definitely yes. This Roast Leg of Lamb with Garlic & Herbs Recipe is elegant yet easy enough to prepare, making it perfect for holiday dinners, celebrations, or any time you want to impress family and friends with a delicious, home-cooked meal.

Ingredients
Meat
- 2 kg Leg of lamb (Bone in)
Herb Paste
- 30 g Fresh mint (Leaves only)
- 30 g Fresh rosemary (Leaves only)
- 30 g Fresh parsley
- 4 Garlic cloves (Peeled)
- 2 Lemons (Zest only)
- 4 tbsp Olive oil
- Sea salt and freshly ground black pepper (to taste)
Instructions
- Preheat the Oven: Set your oven to 180°C fan/200°C/400°F/Gas Mark 6 to ensure it is properly heated for roasting.
- Make the Herb Paste: In a food processor or blender, blitz together the fresh mint, rosemary, parsley, garlic, lemon zest, and olive oil. Add a good pinch of salt and freshly ground black pepper. If needed, add a bit more olive oil to create a smooth paste consistency.
- Prepare the Lamb: Weigh the leg of lamb to determine cooking time. Place the lamb on a baking tray. Using a sharp knife, make small incisions all over the lamb to help the herb paste penetrate the meat.
- Apply the Herb Paste: Rub the prepared herby paste thoroughly all over the lamb, ensuring it gets into the incisions and coats the entire surface evenly.
- Initial Roasting: Place the lamb in the preheated oven and cook for 20 minutes at 180°C fan/200°C/400°F/Gas Mark 6 to develop a flavorful crust.
- Reduce Oven Temperature and Continue Roasting: Lower the oven temperature to 160°C fan/180°C/350°F/Gas Mark 4. Continue to roast the lamb for approximately 15-22 minutes per 500g, depending on your desired level of doneness. For a 2 kg roast, this translates to around 60-88 minutes more.
- Rest the Lamb: Once cooked, remove the lamb from the oven and let it rest covered loosely with foil for at least 15 minutes to retain juices and make carving easier.
Notes
- The cooking time after the initial 20 minutes depends on the weight of the lamb; calculate 15-22 minutes per 500g for best results.
- Resting the meat after roasting is essential to keep it juicy and tender.
- Feel free to adjust the herb paste ingredients according to personal taste or availability.
- Use a meat thermometer to check doneness: 60°C for medium-rare, 70°C for medium, and 75°C for well done.
