If you have a butcher where you shop, ask them to prep the leg for you by removing the fell to skip this step. If not, follow the directions below. Overnight marination deepens the flavor of this traditional holiday meal. Serve with fresh spring vegetables and new potatoes.
Ingredients
- 1 bone-in leg of lamb, between 7 and 8 pounds
For the marinade:
- 6 garlic cloves
- 2 teaspoons coarse sea salt
- 1 teaspoon freshly ground black pepper
- 2 tablespoons whole grain Dijon mustard
- 6 tablespoons extra virgin olive oil, plus more for the cooking rack
- Juice of 1 lemon
- 1 tablespoon fresh rosemary or 1 teaspoon dried rosemary needles
Directions
Step 1
Prep the lamb by removing the fell, the thin membrane overlaying the meat: Place the tip of a sharp thin knife under it at one end to lift it, then tug to pull it away. Trim most of the visible fat but leave a very thin layer in place—this adds to the flavor of the cooked meat. Next, use a paring knife to make uniform 1/2” slits in the meaty parts of the leg. Transfer to a platter.
Step 2
Mince the garlic cloves in a mini chopper, then add the rest of the ingredients and process until smooth. Slather the mixture on the lamb, working it into the slits. Tightly cover the leg with parchment paper, place in a plastic bag, and refrigerate overnight.
Step 3
Set your oven to 400°F. For easy cleanup, line your roasting pan with foil. Place a V-shaped rack in the pan and brush it lightly with olive oil. Place the lamb on the rack, then fill the bottom of the pan with 1/4” water. Place in the oven and roast for 15 minutes. Without opening the oven door, reduce the temperature to 350°F. Continue roasting until an instant-read thermometer inserted in the meatiest part of the leg reaches between 130°F and 135°F, about 20 minutes per pound of lamb.
Step 4
Out of the oven, let the lamb rest for 15 minutes before slicing.
