This recipe focuses on simplicity, allowing the natural flavors of the lamb to shine while being enhanced by garlic, herbs, and a touch of seasoning. Below, you’ll find a detailed recipe and tips to help you master this dish.
1. Classic Roast Leg of Lamb Recipe
Ingredients
- 1 leg of lamb (bone-in or boneless, about 4-6 pounds)
- 5-6 cloves garlic, thinly sliced
- 2 tablespoons fresh rosemary, finely chopped
- 2 tablespoons fresh thyme, finely chopped
- 2 tablespoons olive oil
- 1 tablespoon Dijon mustard
- Salt and freshly ground black pepper, to taste
- Juice of 1 lemon (optional, for a hint of brightness)
Instructions
Prepare the Lamb
Remove the lamb from the refrigerator at least 30 minutes before cooking to bring it to room temperature. Pat it dry with paper towels and place it on a roasting rack inside a baking pan.
Make the Herb Rub
In a small bowl, mix olive oil, rosemary, thyme, Dijon mustard, salt, and pepper.
Season the Lamb
Using a sharp knife, make small incisions all over the lamb. Insert garlic slices into the cuts. Rub the herb mixture evenly over the surface of the lamb. For extra flavor, squeeze fresh lemon juice over the lamb before roasting.
Preheat the Oven
Preheat your oven to 450°F (230°C).
Start Roasting
Place the lamb in the oven and roast at 450°F for the first 15 minutes. This step helps create a flavorful crust.
Lower the Heat
Reduce the oven temperature to 325°F (160°C) and continue roasting based on your desired doneness (see the cooking time chart below). Use a meat thermometer for accuracy.
Note: Always allow the lamb to rest for 15-20 minutes after removing it from the oven. The internal temperature will rise slightly during this time, and the juices will redistribute, ensuring a tender, flavorful roast.
2. Tips for Perfect Roast Leg of Lamb
Choose the Right Cut
Opt for a bone-in leg of lamb for added flavor, or a boneless leg if you prefer easier carving.
Using fresh herbs are best
Although you can certainly substitute dried herbs, fresh herbs are key here, delivering the best kind of flavor.
Dry the Lamb Thoroughly
Patting the lamb dry ensures a better sear and helps the seasonings stick to the surface.
Use a Meat Thermometer
This is the most reliable way to achieve your preferred level of doneness. Insert the thermometer into the thickest part of the meat, avoiding the bone.
Rest the Meat
Never skip the resting period. This step locks in the juices and enhances the texture and flavor of the lamb.
Add Vegetables to the Roasting Pan
Toss potatoes, carrots, and onions with olive oil, salt, and pepper, and let them roast alongside the lamb. They’ll absorb the drippings and turn out deliciously caramelized.
