Preheat the oven to 500°, In a bowl combine butter, Italian seasoning, garlic powder, salt and pepper. Pat dry the roast.
Spread the butter mixture all over the roast. Transfer it into a roasting pan. Put it the oven. Immediately lower the temperature to 475°.
Cook the roast, 7 minutes per pound. 4 pounds = 28 minutes. Turn the oven off. DO NOT OPEN. Leave the roast in the oven to rest for 1 hour. After 1 hour, turn the oven on and set to 200° and continue to cook the roast for another hour. Once that's done take it out of the oven and let it rest for 15-20 minutes before slicing.
