Ingredients
-
1 (5–6 lb) prime rib roast, bone-in
-
6 cloves garlic, minced
-
2 tablespoons fresh thyme leaves, chopped
-
2 teaspoons sea salt
-
1 teaspoon freshly ground black pepper
-
2 tablespoons olive oil
-
1 tablespoon Dijon mustard
-
Optional: fresh rosemary sprigs for garnish
Directions
Prepare the Roast: Begin by removing your prime rib from the refrigerator at least one hour before cooking. Allowing the roast to come to room temperature is an essential step for even cooking. Cold meat placed directly in the oven can result in uneven doneness, with the outside cooking much faster than the center. While the roast is resting at room temperature, take this time to prepare your ingredients and ensure your workspace is organized. Pat the roast gently with paper towels to remove any excess moisture; this step helps the herb rub adhere properly and contributes to a crisp, flavorful crust once roasted.
Preheat the Oven: Preheating your oven is a crucial step to achieving the perfect sear on your prime rib. Set your oven to 450°F (230°C). A preheated oven ensures that the roast develops a rich, golden-brown crust in the first 20 minutes, locking in its natural juices. Position your oven rack in the center to allow for even airflow around the roast. While the oven heats, you can move on to preparing the herb rub and seasoning the meat.
Make the Herb Rub: In a small mixing bowl, combine six cloves of finely minced garlic, two tablespoons of freshly chopped thyme leaves, two teaspoons of sea salt, one teaspoon of freshly ground black pepper, two tablespoons of olive oil, and one tablespoon of Dijon mustard. Using a spoon or small whisk, mix the ingredients until a smooth, uniform paste forms. The garlic and thyme infuse the roast with aromatic flavors, while the Dijon mustard adds subtle tanginess and helps the herb mixture adhere to the meat. This mixture is the key to creating the signature crust that makes this prime rib unforgettable.
Season the Roast: Patting the roast dry once more ensures that the herb rub sticks evenly. Using your hands, gently massage the herb paste over the entire surface of the prime rib, making sure to coat every side, including the ends and corners. Press the rub lightly into the meat so it adheres and forms a uniform layer. This step ensures that every slice of meat will carry the rich, garlicky, herb-infused flavor throughout. Take your time to apply the rub evenly; this attention to detail will result in a beautifully seasoned crust after roasting.
Roasting Setup: Place the prepared prime rib on a roasting rack set inside a shallow roasting pan, fat side up. This position allows the fat to baste the meat naturally during cooking, enhancing flavor and tenderness. Insert a meat thermometer into the thickest part of the roast, avoiding contact with the bone. A thermometer is the most reliable way to monitor doneness, ensuring perfectly cooked meat.
Initial High-Heat Roast: Transfer the roast to the preheated oven and cook at 450°F (230°C) for 20 minutes. This initial high heat step is critical to forming a golden-brown, flavorful crust while sealing in the juices. During this time, the aroma of garlic and thyme will fill your kitchen, creating anticipation for the meal ahead.
Reduce Temperature and Continue Cooking: After the high-heat phase, lower the oven temperature to 325°F (165°C). Continue roasting until the internal temperature reaches your desired level: 120°F (49°C) for rare, 130°F (54°C) for medium-rare, or 140°F (60°C) for medium. Depending on the size of your roast, this stage usually takes 1.5–2 hours. Check the temperature periodically to ensure precision, as overcooking can dry out the prime rib.
Rest the Meat: Once the roast reaches the desired internal temperature, remove it from the oven and cover loosely with aluminum foil. Allow the meat to rest for 20–30 minutes. Resting is a critical step that allows the juices to redistribute throughout the roast, ensuring every slice is tender, juicy, and full of flavor. Do not skip this step, as cutting too soon will cause the juices to escape, leaving a dry exterior.
Carve and Serve: When the roast has rested, carefully slice the meat against the grain to achieve maximum tenderness. Cut into thick, juicy slices to showcase the perfect medium-rare interior and the beautifully browned herb crust. Arrange the slices on a serving platter and garnish with fresh rosemary sprigs if desired. Serve immediately to enjoy the prime rib at its peak flavor and tenderness.
Tips for Perfect Prime Rib
-
Room Temperature Meat: Bringing the roast to room temperature before cooking ensures even doneness throughout.
-
Use a Meat Thermometer: The internal temperature is the most reliable way to achieve your preferred level of doneness.
-
Resting is Essential: Never skip resting. Cutting too soon allows juices to escape, leaving the meat dry.
-
Customize the Herb Rub: Feel free to experiment with other herbs like rosemary or sage for additional flavor.
Side Dish Pairings
A prime rib roast deserves equally impressive accompaniments. Some classic and easy options include:
-
Garlic Mashed Potatoes: Creamy and buttery, they complement the richness of the meat.
-
Roasted Vegetables: Carrots, Brussels sprouts, and parsnips roasted with olive oil and thyme enhance the meal’s aroma.
-
Yorkshire Pudding: A traditional English side that soaks up the roast’s juices beautifully.
-
Horseradish Cream Sauce: Adds a zesty kick that balances the richness of the beef.
Storing and Reheating Leftovers
Prime rib makes excellent leftovers, whether for sandwiches or reheated portions. Here’s how to store and enjoy it later:
-
Refrigeration: Wrap the leftover slices tightly in foil or store in an airtight container. Keep in the fridge for up to 4 days.
-
Reheating: Gently reheat in a 300°F (150°C) oven for 10–15 minutes, or until warmed through. Avoid microwaving, as it can dry the meat.
-
Sandwiches: Thin slices on crusty bread with a smear of horseradish sauce make a luxurious lunch option.
