Notes

This recipe will work for boneless lamb loins and bone-in lamb loins. For bone in rub garlic and herbs on the outside. Bone- in loins will take more time to reach doneness temperature.

It's very important to let the lamb come to room temperature for at least 30 minutes before cooking.

Always let the meat rest on a cutting board for at least 15 minutes before cutting slices.

Optional herbs;

fresh thyme
fresh sage

Garnish with rosemary and thyme sprigs.

To Roast Garlic

Cut the top off of an entire garlic bulb to expose the cloves. Sprinkle it with salt and olive oil. Wrap the head of garlic in aluminum foil. Roast in the oven or the grill for about 45 minutes until the garlic is very soft.
