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

Directions

Step 1

Take the rib roast out of the refrigerator at least 2 hours before cooking to let it come to room temperature.

Step 2

Preheat your oven to 500°F (260°C).

Step 3

In a small bowl, mix together the kosher salt, black pepper, garlic powder, and dried rosemary.

Step 4

Brush the rib roast with olive oil to lightly coat the surface.

Step 5

Rub the seasoning mix all over the roast, making sure to cover it evenly.

Step 6

Place the rib roast, bone side down, on a roasting rack in a roasting pan.

Step 7

Put the roast in the preheated oven and cook at 500°F (260°C) for 20 minutes to create a crust.

Step 8

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.

Step 9

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.

Step 10

Remove the roast from the oven, cover it loosely with foil, and let it rest for 15-20 minutes before carving.

Step 11

Slice and serve the rib roast with your favorite sides.
