Ingredients
Prime Rib
- 5 Pounds Prime Rib (bone-in)
Seasonings
- 3 Tablespoons Kosher Salt
- 1/2 Cup Olive Oil
- 8 Cloves Garlic (mashed)
- 3 Tablespoons Fresh Rosemary (finely chopped)
- 2 Tablespoons Fresh Thyme (finely chopped)
- 2 Teaspoons Onion Powder
- 1 Teaspoon Ground Black Pepper
Instructions
- Prepare Prime Rib: Remove the prime rib from the refrigerator and let it sit at room temperature for approximately two hours before cooking to ensure even cooking throughout.
- Preheat Oven: Preheat your oven to 500°F to prepare for the initial searing stage of cooking.
- Rub Salt: Rub kosher salt evenly all over the prime rib, then set the meat aside as you prepare the marinade.
- Prepare Marinade: In a small bowl, combine olive oil, mashed garlic, finely chopped fresh rosemary, thyme, onion powder, ground black pepper, and an additional pinch of kosher salt.
- Add Marinade: Mix the marinade ingredients thoroughly and rub the mixture all over the prime rib to infuse it with flavor.
- Cook Prime Rib Initially: Place the prime rib into a cast iron skillet without preheating it, then transfer the skillet to the oven and roast for 20 minutes at 500°F to develop a flavorful crust.
- Reduce Heat: After 20 minutes, remove the prime rib and reduce the oven temperature to 325°F.
- Insert Thermometer: Insert a meat thermometer into the top center of the prime rib to monitor internal temperature precisely during cooking.
- Cook to Medium Rare: Return the prime rib to the oven and continue roasting at 325°F until the internal temperature reaches 135°F, about 1.5 hours for medium rare.
- Cool and Foil Tent: Remove the prime rib from the oven and cover loosely with foil to rest and retain juices for approximately 40 minutes.
- Slice and Enjoy: After resting, slice the prime rib against the grain and serve immediately to enjoy tender, flavorful meat.
Notes
- Bringing the meat to room temperature before cooking is essential to ensure even cooking throughout.
- If you don’t have a meat thermometer, estimate cook time based on 15 minutes per pound at 325°F after the initial sear.
- Resting the prime rib covered with foil allows juices to redistribute, resulting in a juicier roast.
- Use a sharp knife to slice the prime rib for clean cuts and to preserve tenderness.
- Bone-in prime rib tends to retain more moisture and adds flavor during roasting.
