I got the roasting idea from Paula Deen. When I first saw this way of cooking I said to myself "Get out of here"! BUT this is great for putting in the oven and going to a movie, spending time with guests, preparing the rest of the meal, or just you time. I changed the time to what worked for me. Seasoned to the way we like it. With lots of Fresh Garlic and Rosemary. I made boneless because that is what was for sale. And makes for easy slicing! The cooking time is the actual time roast is in oven while on. Add 3 hours for resting in cooling oven. Oven Door MUST stay closed.
