Description

This Slow Roast Leg of Lamb recipe features tender, flavorful lamb infused with garlic, fresh rosemary, thyme, and a hint of lemon. Perfectly roasted in the oven until juicy and succulent, this dish is ideal for special occasions or a comforting family dinner.


Ingredients

Meat

  • 1 leg of lamb (about 23 pounds)

Herbs and Seasonings

  • 4 garlic cloves (minced)
  • 2 tablespoons fresh rosemary (finely chopped)
  • 1 tablespoon fresh thyme (chopped)
  • Salt and freshly ground black pepper (to taste)
  • Fresh rosemary sprigs (for garnish)

Other

  • 3 tablespoons extra virgin olive oil
  • Juice of ½ lemon


Instructions

  1. Preheat Oven: Preheat your oven to 375°F (190°C) to prepare it for roasting the leg of lamb evenly and thoroughly.
  2. Prepare the Lamb: Pat the lamb dry with paper towels. Using a sharp knife, make small slits all over the surface to allow the seasoning to penetrate deeply and enhance the flavor.
  3. Make the Seasoning Mixture: In a small bowl, combine minced garlic, finely chopped fresh rosemary, chopped fresh thyme, extra virgin olive oil, lemon juice, salt, and freshly ground black pepper. Mix well to create a flavorful rub.
  4. Rub the Lamb: Spread the seasoning mixture all over the lamb, pressing it into the slits you made earlier to maximize flavor absorption.
  5. Roast the Lamb: Place the seasoned lamb on a rack inside a roasting pan. Roast in the preheated oven for 1½ to 2 hours, depending on your preferred level of doneness.
  6. Check Internal Temperature: For medium-rare, aim for 135°F (57°C); for medium, cook until 145°F (63°C). Use a meat thermometer to check the temperature for perfect results.
  7. Rest the Meat: Remove the lamb from the oven and loosely cover with foil. Let it rest for 15–20 minutes to allow juices to redistribute, ensuring tender and juicy slices.
  8. Serve: Slice the lamb and serve warm, garnished with fresh rosemary sprigs for an aromatic finishing touch.

Notes

  • Make sure to rest the lamb after roasting to maintain juiciness and tenderness.
  • Use a meat thermometer for accurate doneness and prevent overcooking.
  • You can prepare the seasoning rub a few hours ahead and refrigerate for richer flavor penetration.
  • If you prefer, serve with roasted vegetables or a side salad to complete the meal.
