Step-by-Step Grilled Butterflied Leg of Lamb with Herb Rub
1. Preheat the grill to medium-high heat.
Get your grill ready for action, heating it up to about 400°F. This will ensure that your butterflied leg of lamb cooks evenly and develops a beautiful char.
2. Combine the herb rub ingredients.
In a bowl, mix together 3 tablespoons of olive oil with 2 tablespoons each of fresh rosemary and thyme, 4 cloves of minced garlic, 1 teaspoon each of salt and black pepper, plus the freshness of 1 teaspoon lemon zest and the tang from 2 tablespoons lemon juice.
3. Rub the mixture onto the lamb.
Generously coat your butterflied leg of lamb (about 4-5 pounds) with the flavorful herb rub, ensuring every inch is covered. This helps to lock in moisture and flavor as it grills.
4. Marinate the lamb.
Allow your seasoned lamb to sit at room temperature for at least 30 minutes or refrigerate for up to 2 hours. This step enhances the flavors while letting the meat relax before grilling.
