I make these a couple of times each year.

To prep you will need a spray bottle, garlic powder, black pepper and rosemary.

Spray roast with water and liberally cover with garlic powder. The idea here is to get a good crust on the roast. Spray again with water and cover with black pepper. Spray again with water and cover with rosemary. Put on much more than you think you would seem to need. It will seem like alot but the flavor throughout the roast is amazing.

Put in roasting pan on rack. 450 for 15 minutes. Be careful the top can easily burn at this temp so keep an eye on it. Drop down to 325 until internal temp is 120-125 depending on how you like it. Timing just depends on how big your roast is. The one I made on Sunday was 10 lbs and took about 1 1/2 hours.

Remove from oven and let set.
