Grilled Italian Lamb Leg Recipe

Recipe by Pedro M. A. Neves

This grilled Italian lamb leg showcases the rustic flavors of Southern Italy with a marinade of garlic, rosemary, lemon, and extra virgin olive oil. Butterflied and cooked over high heat until charred outside and tender within, it's an elegant yet straightforward centerpiece for any occasion. The smoky exterior contrasts beautifully with the herb-infused meat inside.

Ingredients

• 1 lamb leg (1.8–2 kg / 4–4.5 lbs), butterflied to 4 cm (1.5 inches) thickness by your butcher
• 100 ml (7 tbsp) extra virgin olive oil
• 6 garlic cloves, minced
• 30 ml (2 tbsp) fresh lemon juice
• 15 g (½ oz) fresh rosemary, finely chopped
• 10 g (⅓ oz) fresh thyme, finely chopped
• 1 tsp kosher salt
• ½ tsp black pepper
• 1 tsp Aleppo pepper or red pepper flakes (optional)

Instructions

1. Combine olive oil, minced garlic, lemon juice, rosemary, thyme, kosher salt, black pepper, and Aleppo pepper in a bowl. Whisk until the herbs are evenly distributed throughout the oil.

2. Place the butterflied lamb leg on a large cutting board and pat dry with paper towels. Season both sides evenly with the herb marinade, massaging it gently into the meat.

3. Transfer the lamb to a rimmed tray, cover loosely with plastic wrap, and let rest at room temperature for 15 minutes while you prepare the grill.

4. Preheat a gas grill to high heat (230°C / 450°F) or prepare a charcoal grill with coals spread evenly for direct heat. Oil the grates lightly using a folded paper towel and tongs.

5. Place the lamb skin-side up on the hottest part of the grill. Cook for 4–5 minutes without moving, allowing a dark crust to form.

6. Flip the lamb carefully using long tongs and cook the other side for 4–5 minutes for medium-rare (internal temperature 55–60°C / 130–140°F when checked with an instant-read thermometer at the thickest point).

7. Transfer the lamb to a clean cutting board and let rest for 8–10 minutes, tenting loosely with foil to retain warmth but allow excess steam to escape.

8. Slice the lamb against the grain into 1 cm (0.5 inch) thick pieces. Arrange on a serving platter and drizzle any resting juices over the meat.

Substitutions

• For mint lovers: replace half the rosemary with fresh mint for a Sicilian twist.
• For dairy-free herb butter: mix softened butter with fresh herbs and place a spoonful on each slice just before serving instead of additional oil.
• For a smokier flavor: substitute half the olive oil with walnut oil or use smoked salt in place of kosher salt.
• For a lighter version: reduce olive oil to 60 ml (4 tbsp) and add 30 ml (2 tbsp) dry white wine to the marinade.

Tips

• Always butterfly the lamb to uniform thickness to ensure even cooking; ask your butcher to do this for consistent results.
• Use an instant-read thermometer inserted horizontally into the thickest part of the meat for accurate doneness: 55–60°C (130–140°F) for medium-rare, 60–65°C (140–150°F) for medium.
• Let the meat rest after grilling; this allows residual heat to distribute evenly and reabsorbs the juices, keeping the meat tender and flavorful.
• If grilling indoors on a grill pan, work in two batches to avoid overcrowding, and maintain high heat throughout for proper crust development.

Grilled lamb is celebrated throughout Italy, particularly in the southern regions and islands where Paschal lamb traditions remain strong. This simple preparation reflects the Italian philosophy of letting quality ingredients—aged lamb, good olive oil, and fresh herbs from the garden—speak for themselves without heavy sauces or complicated techniques.
