Ingredients

For the Roasted Lamb with Garlic and Rosemary:

  • 1 (4-5 lb) bone-in leg of lamb, trimmed of excess fat
  • 6 cloves garlic, minced
  • 2 tablespoons fresh rosemary, finely chopped (or 2 teaspoons dried rosemary)
  • 3 tablespoons olive oil
  • 1 tablespoon lemon juice
  • 1 teaspoon Dijon mustard
  • Salt and black pepper to taste
  • 2 tablespoons fresh parsley, chopped (for garnish)
  • Optional: 1 cup red wine or lamb stock (for basting or making gravy)

Special Equipment

While making Roasted Lamb with Garlic and Rosemary doesn’t require any specialized equipment, a few kitchen tools will ensure your success and make the cooking process easier:

  1. Roasting Pan or Baking Dish: A large roasting pan is ideal for cooking the lamb evenly. It helps collect any drippings that can be used for making a sauce or gravy.
  2. Meat Thermometer: A meat thermometer is essential for checking the doneness of the lamb. This ensures that the lamb is cooked to your preferred level of doneness without overcooking it.
  3. Sharp Knife: A sharp knife is necessary to trim any excess fat from the lamb and to make clean cuts for carving once the lamb is cooked.
  4. Pastry Brush: A pastry brush will help you evenly apply the garlic and rosemary mixture to the lamb, ensuring that every inch of the meat is flavored.
  5. Aluminum Foil: If you want to tent the lamb while it rests, aluminum foil can help keep the meat warm without overcooking it.
  6. Carving Knife: After the lamb has rested, use a sharp carving knife to slice it into beautiful, even portions.

Step-by-Step Instructions

1. Prepare the Lamb

Start by preparing the leg of lamb. Trim off any excess fat and silverskin from the lamb using a sharp knife. You don’t want to remove all of the fat, as it helps keep the meat moist during roasting, but you can remove any large chunks of fat that might make the dish greasy.

Once the lamb is trimmed, make several small incisions in the surface of the meat using the tip of your knife. These incisions will help the garlic and rosemary mixture penetrate the meat and infuse it with flavor.

2. Make the Garlic and Rosemary Marinade

In a small bowl, combine the minced garlic, finely chopped rosemary, olive oil, lemon juice, and Dijon mustard. Stir the ingredients together until well combined. This mixture will serve as your marinade for the lamb.

Generously season the lamb with salt and black pepper. Then, use a pastry brush or your hands to rub the garlic and rosemary mixture all over the surface of the lamb, making sure to coat the meat evenly, especially in the incisions. If you have time, let the lamb marinate for at least 30 minutes to allow the flavors to meld together, though you can also proceed immediately to the next step.

3. Preheat the Oven

Preheat your oven to 400°F (200°C). This high temperature will help sear the exterior of the lamb, creating a flavorful crust while the inside remains tender and juicy.

4. Roast the Lamb

Place the prepared lamb into a roasting pan or baking dish, fat side up. This positioning allows the fat to render as the lamb cooks, helping to keep the meat moist and flavorful.

Roast the lamb in the preheated oven for about 15 minutes to create a nice sear on the outside. After 15 minutes, reduce the oven temperature to 350°F (175°C) and continue roasting the lamb for about 1 hour to 1 hour 15 minutes, or until the meat reaches your desired level of doneness.

  • For medium-rare: The internal temperature should reach 130°F (54°C).
  • For medium: The internal temperature should reach 140°F (60°C).
  • For well-done: The internal temperature should reach 160°F (71°C).

Baste the lamb occasionally with the pan drippings, or if you prefer, you can add a cup of red wine or lamb stock to the pan to keep the lamb moist and enhance the flavor.

5. Rest the Lamb

Once the lamb has reached your preferred doneness, remove it from the oven and tent it with aluminum foil. Let it rest for at least 15-20 minutes before carving. Resting the meat allows the juices to redistribute throughout the lamb, making it more tender and flavorful.

6. Carve and Serve

After the lamb has rested, use a sharp carving knife to slice it against the grain into thick or thin slices, depending on your preference. Arrange the slices on a platter and garnish with freshly chopped parsley for a burst of color and freshness.

Serve the roasted lamb with your choice of sides, such as roasted vegetables, mashed potatoes, or a fresh salad.

Tips for Perfect Roasted Lamb with Garlic and Rosemary

  • Use Fresh Rosemary: Fresh rosemary has a more vibrant, aromatic flavor than dried rosemary. If you’re using dried rosemary, reduce the amount to about 2 teaspoons to avoid overpowering the dish.
  • Don’t Overcook the Lamb: Lamb is best when cooked to medium-rare or medium. Overcooking can result in dry, tough meat. Use a meat thermometer to ensure the lamb is cooked to perfection.
  • Let the Lamb Rest: Resting the lamb after roasting is essential for achieving the best texture and flavor. It allows the juices to settle and makes the meat more tender.
  • Baste for Extra Flavor: Basting the lamb with its own drippings during roasting will help keep the meat moist and add extra flavor. If you want more flavor, add a little red wine or lamb stock to the pan to create a sauce while the lamb cooks.
  • Adjust the Seasonings: If you prefer a more intense flavor, you can add more garlic or rosemary to the marinade. You can also experiment with other herbs, such as thyme or oregano, for a different twist on the classic recipe.

Variations of Roasted Lamb with Garlic and Rosemary

  • Lamb with Mint Sauce: A classic pairing for roasted lamb, mint sauce provides a refreshing contrast to the savory flavor of the lamb. Serve the lamb with a side of homemade or store-bought mint sauce.
  • Lamb with Mustard and Herbs: If you enjoy the flavor of mustard, try coating the lamb with a mixture of Dijon mustard, honey, and fresh herbs for an extra layer of sweetness and tang.
  • Spicy Roasted Lamb: For a kick of heat, add red pepper flakes or cayenne pepper to the garlic and rosemary marinade. This will infuse the lamb with a subtle spiciness that pairs well with the rich flavor of the meat.
  • Roast Rack of Lamb: Instead of a leg of lamb, you can also make this recipe with a rack of lamb. The preparation and roasting method are similar, but the rack will cook faster and have a slightly different presentation.

Storage and Shelf Life

Roasted Lamb with Garlic and Rosemary is best enjoyed fresh, but you can store any leftovers in an airtight container in the refrigerator for up to 3-4 days. To reheat, gently warm the lamb in the oven or microwave, being careful not to dry it out.

For longer storage, you can freeze the cooked lamb. Wrap it tightly

in plastic wrap or aluminum foil, then place it in a freezer-safe bag or container. Frozen lamb will last for up to 3 months. To thaw, let it sit in the refrigerator overnight before reheating.

Side Dishes and Pairings for Roasted Lamb with Garlic and Rosemary

Pair this succulent lamb with complementary sides to create a well-rounded and memorable meal:

  • Roasted Vegetables: Roasted potatoes, carrots, and parsnips are perfect sides for roasted lamb. The caramelized flavors of the vegetables pair wonderfully with the rich lamb.
  • Mashed Potatoes: Creamy mashed potatoes with butter and cream make a comforting accompaniment to lamb.
  • Greek Salad: A fresh Greek salad with tomatoes, cucumbers, olives, and feta cheese offers a refreshing contrast to the richness of the lamb.
  • Gravy: If you’ve made a pan sauce or gravy from the lamb drippings, serve it alongside the lamb for added flavor.
