Make-Ahead:
The lamb can be assembled (not roasted) up to 1 day ahead, covered and refrigerated. Let the lamb stand at room temperature for 30 minutes before roasting.
To prepare the lamb:

Preheat the oven to 350°F.

Soak the rosemary branches in cold water for 1 hour. This will help prevent the rosemary from burning while they are in the oven.

Heat a heavy large cast-iron griddle pan over high heat. Sprinkle the leg of lamb generously with salt and pepper. Sear the leg of lamb until brown on all sides, about 5 minutes. Transfer the lamb to a baking sheet. 

In a Bump and Grind or another mortar and pestle, combine the olives, garlic, chopped rosemary, and pepper flakes. Pound the olive mixture until the olives break apart. Mix in the olive oil.

Lay the strands of kitchen twine horizontally across a large rimmed baking sheet, spacing them evenly apart. Lay the rosemary branches perpendicularly atop the twine. Stuff some of the olive mixture into the lamb cavity and spread the remaining olive mixture over the lamb.

To roast the lamb:

Arrange the lamb at an angle on the baking sheet so that it fits properly. Roast the lamb until an instant-read meat thermometer registers 125°F when inserted into the thickest part of the lamb meat, turning the lamb occasionally, about 1 hour and 30 minutes.

Transfer the lamb to a carving board and let rest for 30 minutes.

To serve:

Remove the twine and rosemary from the lamb. Carve the lamb into slices and transfer to a platter and serve with any accumulated juices.

To prepare the lamb:

Preheat the oven to 180°C.

Soak the rosemary branches in cold water for 1 hour. This will help prevent the rosemary from burning while they are in the oven.

Heat a heavy large cast-iron griddle pan or frying pan over high heat. Sprinkle the legs of lamb generously with salt and pepper. Working with one at a time, sear the legs of lamb until brown on all sides, about 5 minutes. Transfer the lamb legs to a baking tray.

In a mortar and pestle, combine the olives, garlic, chopped rosemary, and chilli flakes. Pound the olive mixture until the olives break apart. Mix in the olive oil.

Lay half of the strands of kitchen twine horizontally across a large rimmed baking tray, spacing them evenly apart. Lay half of the rosemary branches perpendicularly atop the twine. Stuff some of the olive mixture into the lamb cavity of each leg and spread the remaining olive mixture over the lamb legs.

Set one lamb leg on top of the twines and rosemary. Starting with the center twine and working toward the outer twines, tie the twine as tight as possible around the lamb and rosemary, completely encasing the lamb with the rosemary. Repeat with the remaining twines, rosemary, and lamb leg.

To roast the lamb:

Arrange each lamb leg at an angle on the baking trays so that they fit properly. Roast the lamb until an instant-read meat thermometer registers 50°C when inserted into the thickest part of the lamb meat, turning the lamb occasionally, about 1 hour and 15 minutes.

Transfer the lamb to a carving board and let rest for 30 minutes.

To serve:

Remove the twine and rosemary from the lamb. Carve the lamb into slices and transfer to a platter and serve with any accumulated juices.
