Ingredients
Scale
- 5–7 lb. Bone-in Prime Rib Roast
- 5 garlic cloves, minced
- 2 1/2 teaspoons truffle salt
- 2 teaspoons black pepper
- 1 tablespoon fresh rosemary
- 1 tablespoon fresh thyme
- 1 tablespoon fresh oregano
- 1/3 cup unsalted butter, softened
- 1 large yellow onion
- 1 head of garlic, sliced in half
- 8 sprigs of thyme
- 2 sprigs of rosemary
Instructions
- Remove your covered roast from the refrigerator and let it rest for 30 minutes prior to roasting to bring to room temperature.
- Prepare your roasting pan by adding 1 large onion to the bottom along with the whole head of garlic (sliced in half, flesh side up), 8 sprigs of thyme, and 2 sprigs of rosemary. Set aside.
- Pat the Prime Rib Roast dry with a paper towel.
- Preheat oven to 225 degrees F.
- In a small bowl, add minced garlic, truffle salt, black pepper, fresh rosemary, fresh thyme, and fresh oregano. Mix together.
- Remove 1 tablespoon of the mixture and add it to another small bowl with 1/3 cup softened unsalted butter. Mix together, then set aside.
- To the bowl with the remaining herb mixture, add 2 tablespoons of olive oil and mix together to form a paste.
- Rub the garlic herb paste all over the Prime Rib using your hands and place bone side down on a rack in the roasting pan.
- Roast, uncovered, for 3-4 hours, time will vary depending on the size of your roast. Using an instant-read thermometer, check the temperature of the roast.
- When the center of the roast reaches 120 degrees F (for medium rare), remove from the oven and tent with tin foil for 20 minutes. Turn oven up to 500 degrees F.
- Once the oven reaches 500 degrees F, remove the tin foil tent and rub the garlic herb butter on the top and sides of the roast.
- Place the roast back in the oven, uncovered, for 15-20 minutes to brown the outside.
- Remove the prime rib roast from the oven and place on a cutting board to rest for 20 minutes.
- Serve with horseradish sauce or au jus.
