Yield: 4 servings

Description

The simplest, most fail-safe version for cooking a Prime Rib - boneless or bone-in.

Ingredients

5 pounds prime rib roast
1 tablespoon kosher salt
2 tablespoons very soft unsalted butter
1 tablespoon kosher salt
2 teaspoons freshly ground black pepper
1/8 teaspoon cayenne pepper

Directions

1 Gather all ingredients.
2 Place beef on a pan, and rub with salt. Place meat on a rack or twisted foil so air can circulate under roast, and transfer to the fridge for 24 to 48 hours.
3 Remove from the refrigerator and let it rest for a few hours to come to room temperature (optional).
4 Preheat the oven to 300 degrees F (150 degrees C). Transfer roast into a roasting pan, preferably on a rack.
5 Mix butter with coarse salt, pepper, and cayenne in a small bowl and spread onto the sides and top of the roast. Then add more salt to the top. Pour water into the bottom of the pan.
6 Roast in the preheated oven until internal temperature is 115 to 120 degrees F (46 to 48 degrees C), about 1 hour and 20 minutes (about 20 minutes per pound). Remove from the oven, cover with foil and let rest for at least 20 minutes before serving.
7 Drippings from the pan can be deglazed with broth or water, and served alongside meat.
