Merry Christmas Nancy. Very well explained recipe. It is always a success. Have a boneless, already seasoned, leg of lamb and have been studying these instructions as well as the comments.

The question I have is about the meat thermometer. The one that we have is a digital thermometer that stays in the meat the whole time it cooks with a timer when it reaches the desired temp. Is this okay to use? Damn near perfect recipe. Cannot stress enough how important it is to get your lamb to room temperature before cooking — as with any meat roasting.

It needs to be the same temperature throughout to cook evenly. I did find the cooking times a little off — so as the author noted you really must go by temperature. My little leg took a fair bit longer to get to medium.

I have a question, actually. I am in the process of cooking a boneless leg of lamb. I planned to use an internal thermometer which we have had for many years. All the thermomoters that you mention are to be used after the meat is removed from the oven. I believe that my old one is a leave-in thermometer. So, my question is do accurate leave-in thermometers exist and if so, do you recommend any? I tested this recipe with a small roast for just my hubby and me and it turned out fabulous!!

I understand that I can smoke and roast the meat in the netting. My question is what is the max temperature the netting can handle, as I plan to reverse sear the roast in a cast iron pan once it get to degrees?

It depends on what type of netting is covering the leg of lamb. If it is cotton then yes, sear away. If it is plastic, the plastic netting may melt while searing at a high temperature. A better option is to remove the plastic netting and retie the roast with cotton string.

You can even add some seasoning inside the roast before retying. We are having Boneless Leg of Lamb roast for Thanksgiving! Sooo good. Let us know how it turns out!
