Leg of Lamb en Cocotte with Garlic and Rosemary

Ingredients

1 boneless leg of lamb shank end, (4- to 5-pound), trimmed and tied (see "Tying a Boneless Lamb Roast" below)Salt and ground black pepper 2 tablespoons olive oil 8 medium garlic cloves, peeled and sliced thin2 sprigs fresh rosemary

Before You Begin

We prefer the shank end of the boneless leg of lamb here (rather than the sirloin end). There are two methods butchers use to remove the bone from the meat, referred to as corkscrewed and butterflied; we find the corkscrewed type much easier to work with but a butterflied leg of lamb will also work.

Instructions

  1. Adjust an oven rack to the lowest position and heat the oven to 250 degrees. Pat the lamb dry with paper towels and season with salt and pepper.
  2. Heat the oil in a large Dutch oven over medium-high heat until just smoking. Brown the lamb well on all sides, 7 to 10 minutes, reducing the heat if the pot begins to scorch. Transfer the lamb to a large plate.
  3. Pour off all of the fat from the pot. Add the garlic and rosemary and nestle the lamb, with any accumulated juices, into the pot. Place a large sheet of foil over the pot and press to seal, then cover tightly with the lid. Transfer the pot to the oven and cook until the very center of the lamb registers 125 degrees on an instant-read thermometer (for medium-rare), 45 to 60 minutes.
  4. Remove the pot from the oven. Transfer the lamb to a cutting board, tent with foil, and let rest for 20 minutes. Remove the rosemary from the jus in the pot, then cover to keep the jus warm.
  5. Remove the twine, slice the lamb into 1/4-inch-thick slices against the grain, and transfer to a serving platter. Spoon the jus over the lamb and serve.

Why This Recipe Works

For our lamb en cocotte recipe, we selected readily available leg of lamb that had been butchered in corkscrew fashion. We trimmed much of the fat off the lamb in order to eliminate any gamy flavor and then tied the lamb roast to ensure even cooking. With our leg of lamb trimmed, tied, and ready to go, the recipe was simply a matter of following the en cocotte method for our lamb en cocotte recipe: We seared the lamb on all sides, removed the pot from the heat, discarded any accumulated fat in the pot, and added rosemary and garlic to the pot with the lamb just before it went into the oven.
