Ingredients

• 6 pounds bone-in prime rib roast
• 2 tablespoons kosher salt
• 2 tablespoons black pepper
• 1 tablespoon garlic powder
• 2 tablespoons fresh rosemary
• 2 tablespoons fresh thyme
• 3 tablespoons olive oil
• 4 tablespoons unsalted butter
• 4 cloves garlic cloves, minced

Directions

Step 1

Remove the prime rib roast from the refrigerator 2 hours before cooking and allow it to come to room temperature.

Step 2

Preheat your oven to 450°F (230°C).

Step 3

In a small bowl, mix the kosher salt, black pepper, and garlic powder. Rub this mixture generously all over the surface of the roast, including the fat cap and sides.

Step 4

In another small bowl, mix the fresh rosemary, fresh thyme, and olive oil to create a herb paste.

Step 5

Rub the herb paste evenly over the roast, ensuring it is fully coated.

Step 6

Place the roast on a roasting rack in a large roasting pan, bone side down, and fat side up.

Step 7

Roast the prime rib in the preheated oven at 450°F (230°C) for 20 minutes to sear the exterior.

Step 8

Reduce the oven temperature to 325°F (165°C) and continue roasting until the internal temperature reaches your desired doneness (125°F for medium-rare; around 90-100 minutes).

Step 9

While the roast is cooking, prepare the garlic butter by melting unsalted butter in a small saucepan over medium heat. Add minced garlic and stir for 1-2 minutes until fragrant. Remove from heat and set aside.

Step 10

Once the roast reaches the desired temperature, remove it from the oven, tent it loosely with aluminum foil, and let it rest for 20-30 minutes. The internal temperature will rise slightly as it rests.

Step 11

Before carving, brush the roast with the prepared garlic butter for an extra layer of flavor.

Step 12

Carve the prime rib roast into thick slices and serve hot with your favorite accompaniments, such as horseradish sauce or au jus.
