Prime Rib is a special cut of meat that is the highlight of many holiday meals!
Coat the prime rib with salt, and let it rest for 30 minutes.
Preheat the oven to 500°F.
In a medium bowl, mix together the butter, garlic, rosemary, thyme, and pepper.
Spread the butter mixture evenly over the ribeye roast.
Bake for 25 minutes.
Turn off the oven heat, but leave the ribeye roast in the oven for 2 hours. Be sure to leave the oven door shut so that no heat can escape. I recommend beginning to check the internal temperature after about an hour and a half.
Remove the roast from the oven. Transfer it to a carving board and pour the pan drippings into a medium saucepan.
Heat the drippings over medium heat. Whisk in the flour and beef stock until thickened.
Remove from the heat and strain out any clumps.
Slice the prime rib and serve with gravy.
