Preheat oven to 500 degrees.

Place roast in a roasting pan, brush with oil, and sprinkle the spices over the roast.

Flip roast so the fat side is up.

Place in oven and roast for 25 minutes at 500 degrees.

Turn the oven down to 200 degrees and cook for 25 minutes per pound or until the internal temperature is at least 145 degrees.

Remove from oven and let rest for 20 minutes.

Slice and serve.
