1/4 c. plus 1 tablespoon extra-virgin olive oil, plus more greasing
3 cloves garlic, minced
1 tbsp. minced rosemary, plus 2 sprigs
1 tbsp. minced thyme
1 (6 lb.) leg of lamb
kosher salt
Freshly ground black pepper
2 heads garlic, cloves peeled
8 oz. cipollini onions
2 lemons, halved
Directions
Heat oven to 400°. In a small bowl, combine 1/4 cup oil, garlic, chopped rosemary, and thyme.
Place lamb in a large roasting dish, then season all over with salt and pepper.
Brush herb oil all over lamb (you won’t use it all right now). Roast 30 minutes.
Meanwhile, in a medium bowl, stir together whole garlic cloves, onions, rosemary sprigs, and lemons with 1 tablespoon oil, salt, and pepper.
Reduce oven to 350°. Spread garlic, onions, rosemary, and lemon halves evenly around lamb, then coat lamb in more herb oil. Add ¼ cup water to roasting dish, then roast for 1 to 1 ½ hours more, until meat thermometer inserted into the thickest part of the roast registers about 145° to 150°.
Let lamb rest 15 minutes before carving and serving.
