Preheat oven to 500 degrees.
Place roast in a baking dish, coat with olive oil on all sides, sprinkle with salt and pepper, press mixed chopped herbs all over roast.
Place roast in oven, reduce heat to 475 degrees.
Cook roast 7 minutes per pound at 475 degrees (that’s 21 minutes for a 3 lb roast).
Do not open the oven door. Turn off the oven and continue to cook for 2 ½ hours, making sure to not open the oven door at all during this entire time.
After the 2 ½ hours, remove from oven, placing a piece of foil over the top and let rest for about 10 minutes.
