Make several small insicions all over the roast stuff pieces of garlic in the holes.
Mix oil, Herbs de Provence black pepper and 1 teaspoon salt together in a bowl. Rub mixture all over meat. Place meat on a rack in a shallow roasting pan. Scatter mushrooms around the roast if using. Roast in oven for 1 hour or until the internal temperature reaches 130 degrees for medium rare.
Remove roast from the oven, sprinkle with salt, loosely cover and let stand for 15 minutes. The roast will continue to cook during this time.
Slice thin, about 1/4 inch, and serve.
Notes
It is very important to let the roast rest before slicing. It will redistribute the juices and help ensure a juicy roast.Again, the mushrooms are totally optional as they don't add any flavor to the roast itself. That being said, I loved serving them on the side or to stir into my mashed potatoes. If they look like they are getting dry, you might need to remove them before the roast. Just keep them covered to keep warm. Nutrition information for estimation purposes only.
