Recipe Information
Ingredients
- 5 pounds bone-in rib roast (prime rib)
- 2 tablespoons kosher salt
- 1 tablespoon freshly ground black pepper
- 1 teaspoon garlic powder
- 1 teaspoon dried rosemary
- 2 tablespoons olive oil
Instructions
Take the rib roast out of the refrigerator at least 2 hours before cooking to let it come to room temperature.
Preheat your oven to 500°F (260°C).
In a small bowl, mix together the kosher salt, black pepper, garlic powder, and dried rosemary.
Brush the rib roast with olive oil to lightly coat the surface.
Rub the seasoning mix all over the roast, making sure to cover it evenly.
Place the rib roast, bone side down, on a roasting rack in a roasting pan.
Put the roast in the preheated oven and cook at 500°F (260°C) for 20 minutes to create a crust.
After 20 minutes, turn the oven off but do not open the door. Allow the roast to continue cooking in the residual heat for about 1 hour and 40 minutes.
Check the internal temperature of the roast with a meat thermometer. It should read 130°F (54°C) for medium-rare. Adjust resting time as necessary.
Remove the roast from the oven, cover it loosely with foil, and let it rest for 15-20 minutes before carving.
Slice and serve the rib roast with your favorite sides.
