Our easy way of doing them here mixing up soft butter with garlic, pepper, kosher salt, and whatever else you like. Covering the roast with the butter as thick as you can make it.
Pre heat an oven to broil and cook for 5 minutes per pound of roast. Once you’ve reached the time limit DO NOT open the oven. Just shut it off and let it sit in their for an hour. It should have a great crust on it and be medium rare in the middle.
The other way we do it is a dry rub, sear the outsides for 2 minutes on every piece you can get to then chuck it on the Traeger or similar at 225 until it hits 125 or your preferred temp internal.
Either is excellent.
