Roasting a leg of lamb is a timeless culinary tradition that brings out the rich, savory flavors of the meat. This recipe combines aromatic herbs and garlic to create a succulent and flavorful dish perfect for any special occasion or family gathering.
If you don't already have rosemary and thyme in your pantry, you'll need to pick them up at the supermarket. Fresh herbs are essential for this recipe as they impart a more vibrant flavor compared to dried ones. Additionally, ensure you have a good quality olive oil to enhance the richness of the lamb.
Ingredients for Roasted Leg of Lamb Recipe
Leg of lamb: The main protein, a whole leg of lamb, is the star of this dish.
Garlic: Sliced and inserted into the lamb to infuse it with a deep, aromatic flavor.
Olive oil: Used to coat the lamb, helping to keep it moist and adding a rich taste.
Rosemary: Freshly chopped, this herb adds a piney, slightly peppery flavor.
Thyme: Another fresh herb, thyme brings a subtle earthiness to the dish.
Salt: Enhances the natural flavors of the lamb and other ingredients.
Black pepper: Freshly ground to add a bit of heat and complexity to the seasoning.
Technique Tip for This Recipe
When preparing the leg of lamb, make sure to let it come to room temperature before roasting. This ensures even cooking throughout the meat. Additionally, when making the small incisions for the garlic, use a sharp knife and insert the slices deeply to infuse the lamb with maximum flavor. For a more aromatic dish, consider marinating the lamb with the olive oil, rosemary, thyme, salt, and pepper mixture for a few hours or overnight. This allows the flavors to penetrate the meat more thoroughly.

How to Store or Freeze This Dish
Allow the roasted leg of lamb to cool completely at room temperature before storing. This helps prevent condensation, which can lead to sogginess and spoilage.
Once cooled, wrap the lamb tightly in aluminum foil or plastic wrap to maintain its moisture and flavor. Alternatively, you can place it in an airtight container.
Store the wrapped or containerized lamb in the refrigerator if you plan to consume it within 3-4 days. This ensures the meat remains fresh and safe to eat.
For longer storage, consider freezing the roasted leg of lamb. Place the wrapped lamb in a heavy-duty freezer bag or an airtight container. Label it with the date to keep track of its freshness.
When freezing, try to remove as much air as possible from the freezer bag to prevent freezer burn, which can affect the texture and taste of the lamb.
To reheat, thaw the lamb in the refrigerator overnight. This slow thawing process helps retain the meat's moisture and flavor.
Reheat the lamb in a preheated oven at 325°F (165°C) until it reaches an internal temperature of 165°F (74°C). Cover it with foil to prevent it from drying out.
Alternatively, you can reheat slices of the lamb in a skillet over medium heat with a bit of olive oil or butter to keep it juicy and flavorful.
