Remove the prime rib from its packaging and separate the bones.
Pat the roast and bones dry with paper towels.
Generously season all sides of the roast and the bones with salt and pepper.
Tie the bones back onto the roast using butcher string.
In a small bowl, mix softened butter, garlic paste, and Italian herb paste until combined.
Using your hands or a basting brush, coat the entire roast generously with compound butter, including the underside.
Place the roast bone side down in a roasting pan.
Roast at 450 degrees for 15 minutes to develop a crust.
Reduce oven temperature to 325 degrees and continue cooking until desired doneness is reached.
