Pat the beef prime rib roast with paper towels to dry the meat before seasoning it. This way, the seasoning sticks to it better during the cooking process.
Place the prime rib in a roasting pan, fat side up.
Prepare a paste in a small bowl with enough oil, salt and ground pepper that you’ll use to cover the surface of your roast on all sides.
Add other rub flavorings, such as mustard seeds or freshly ground coffee, to achieve the taste you desire.
You can omit the oil if you want, but it does a great job of sealing in the juices of the meat during cooking.
Rub the seasoning paste into the meat all over.
If you’re going to use garlic to season your roast, cut a dozen or more 1”-deep slits in both the top and bottom of the beef roast using a paring knife.
Insert a sliver of garlic clove into each slit.
Let the prepared prime rib roast rest in the pan for up to two hours before placing it in the oven.
