9-10 lb Bone in Prime Rib Roast (about 5 bones) - tied
8 Tbs Unsalted Butter - softened
10-12 cloves Fresh Garlic - minced fine
3 Tbs Fresh Thyme Leaves - minced
Kosher Salt to taste
Fresh Ground Black Pepper to taste
Preparation:
Place your roast on a platter and allow to sit at room temperature for 1-2 hours
Preheat oven to 450ºF
Using a sharp paring knife, score the meat with shallow (no more than ⅛ inch deep) cuts in a diamond pattern
Thoroughly combine the butter, garlic, and thyme - Spread the mixture evenly over the entire roast - Generously season all sides with salt and pepper
Transfer the roast to a roasting pan with a rack rib side down/fat side up
Place in the center of the oven and allow to roast for 30 minutes
After 30 minutes, reduce oven temp to 350ºF and continue to cook until an internal temperature of 115 -120ºF is reached - NOTE: A probe or instant read thermometer is essential to make sure that the roast is removed from the oven at the right time because roasting time varies quite a bit (a general rule of about 15 minutes to a pound is good for estimating time needed)
As soon as an internal temperature of 115-120 ºF is reached, remove from oven and loosely tent with foil - Allow to rest 20 minutes before slicing and serving (internal temp will rise to 130-135ºF = medium rare)
To serve, carve down along the ribs to separate them from the bulk of the meat and then slice between each rib - Slice the roast across the grain and serve with your choice of sauce (creamy horseradish or a red wine reduction made with the pan drippings are the most 'traditional') as the centerpiece of the meal alongside your choice of side dishes
