How To Make Ina Garten Prime Rib Roast
- Bring to room temperature: Remove the roast from the fridge 2 hours before roasting for even cooking. Pat dry with paper towels.
- Make the herb rub: In a bowl, combine olive oil, garlic, rosemary, thyme, salt, and pepper.
- Season the roast: Rub the herb mixture all over the prime rib and let it rest for at least 30 minutes at room temperature.
- Slow roast the prime rib: Preheat oven to 250°F (120°C). Place the roast fat-side up on a rack in a roasting pan.
-
Roast until desired doneness: Cook for 3 to 3 1/2 hours, or until the internal temperature reads:
- 120°F for rare
- 125°F for medium-rare
- 130°F for medium
- Rest the meat: Remove from oven and tent with foil for 30–45 minutes to retain juices.
- Sear for a crispy crust: Increase oven to 500°F (260°C). Return roast to oven for 5–10 minutes to crisp and brown the outside.
- Slice and serve: Carve the roast into thick or thin slices. Serve with horseradish sauce or au jus.
