The Perfect Reverse Sear Prime Rib

For the Prime Rib

• ▢ 1 10-pound bone-in standing rib roast: Choose a well-marbled roast for optimal flavor and tenderness.
• ▢ 2 tablespoons kosher salt: Essential for dry brining and seasoning.
• ▢ ½ cup unsalted butter at room temperature: For the rich, flavorful herb crust.

For the Garlic-Rosemary Crust (Optional, but highly recommended)

• ▢ 2 tablespoons minced fresh rosemary: Adds an aromatic, earthy note.
• ▢ 1 tablespoon minced garlic approximately 5 large cloves: A pungent aromatic for depth of flavor.
• ▢ freshly ground black pepper to taste: For a sharp, spicy kick.

For the Jus (Optional, but highly recommended)

• ▢ 4 tablespoons prime rib drippings: The flavorful foundation of your jus, collected from the roasting pan.
• ▢ 4 tablespoons dry red wine or low-sodium beef broth: For deglazing the pan and adding depth.
• ▢ 2 cups low-sodium beef broth: To form the savory liquid base.
• ▢ salt to taste: To adjust seasoning.
• ▢ freshly ground black pepper to taste: To round out the flavor profile.

For the Horseradish Sauce (Optional, but highly recommended)

• ▢ 1 cup full-fat sour cream: Provides a creamy, tangy base.
• ▢ ½ cup full-fat mayonnaise: Adds richness and smoothness.
• ▢ 2 tablespoons prepared horseradish: The signature spicy kick. Adjust to your heat preference.
• ▢ 1 teaspoon white wine vinegar: Brightens the flavors and adds a touch of acidity.
• ▢ ½ teaspoon salt more or less to taste: Season to your liking.

Preparing the Horseradish Sauce

• In a small mixing bowl, combine 1 cup full-fat sour cream, ½ cup full-fat mayonnaise, 2 tablespoons prepared horseradish, 1 teaspoon white wine vinegar, and ½ teaspoon salt. Using a whisk, stir all ingredients together until they are thoroughly blended and smooth. Taste and adjust salt or horseradish if desired.
• Cover the bowl tightly with a lid or food-safe plastic wrap. Place it in the refrigerator to chill for at least 1 hour. Chilling allows the flavors to meld beautifully, enhancing the sauce’s zest and creaminess. This can be prepared a day in advance for convenience.

The Reverse Sear Prime Rib Process

• Begin by placing your magnificent 1 10-pound bone-in standing rib roast onto a large roasting pan, preferably fitted with a wire rack to allow for even air circulation.
• Generously sprinkle 2 tablespoons of kosher salt over all sides of the rib roast, ensuring a thorough and even coating. This dry brining step is crucial for tenderizing the meat and enhancing its flavor.
• Loosely cover the seasoned rib roast with food-safe plastic wrap, or leave it uncovered if your refrigerator is clean and free of strong odors. Place the roasting pan in the refrigerator and chill for a significant period, anywhere from 8 to 12 hours. This extended chill time allows the salt to penetrate deeply, transforming the meat’s texture and seasoning it from within.
• After the chilling period, remove the roasting pan from the refrigerator and discard the plastic wrap. Let the rib roast stand at room temperature for approximately 30 minutes to 1 hour. This step is vital for ensuring the roast cooks evenly, preventing the outer layers from overcooking while the center remains too cool.
• Preheat your oven to a low temperature of 200° Fahrenheit (93° Celsius). This gentle heat is key to the “low-and-slow” aspect of the reverse sear, promoting even cooking and maximum juiciness.
• In a separate small mixing bowl, combine ½ cup of room temperature butter, 2 tablespoons of minced fresh rosemary, 1 tablespoon of minced garlic, and a generous amount of freshly ground black pepper. Mix these ingredients thoroughly until they are well incorporated, forming a fragrant herb butter.
• Using a basting brush or your hands, spread the aromatic herb butter mixture evenly over all surfaces of the rib roast. This butter crust will contribute significantly to the final flavor and the beautiful caramelized exterior.
• Carefully place the roasting pan with the prepared rib roast into the preheated 200°F oven. Roast for approximately 3 hours, or until the internal temperature of the rib roast reaches your desired doneness (e.g., 115° Fahrenheit for medium-rare, keeping in mind carry-over cooking). Use an internal meat thermometer inserted into the thickest part of the roast, avoiding the bone, for accurate measurement. Note: Refer to the “Internal Temperatures for Desired Doneness” section below for specific temperatures.
• Once the rib roast reaches the target internal temperature, carefully remove the pan from the oven. Tent the pan loosely with aluminum foil to trap some heat and allow the roast to rest for 20 minutes. This resting period is critical for the juices to redistribute throughout the meat, ensuring every slice is succulent. The internal temperature will also continue to rise by a few degrees during this time (carry-over cooking).
• While the roast is resting, increase your oven temperature dramatically to 500° Fahrenheit (260° Celsius). This high heat is what will create the spectacular crispy crust.
• When the oven has fully reached 500° Fahrenheit, uncover the roast and return the pan to the oven. Bake the roast for 5 to 10 minutes, or until all sides are beautifully browned and caramelized, forming a crisp crust. Keep a close eye on it during this phase, as the high heat can quickly lead to burning.
• Once the prime rib has achieved its gorgeous crust, remove the pan from the oven and set it aside while you prepare the accompanying au jus. There is no need for further resting after this searing step, as the juices have already redistributed.

Crafting the Perfect Jus

• While your magnificent prime rib is resting or after its final sear, retrieve a medium saucepan and place it on your stovetop over high heat. This will be used to create the flavorful jus.
• Carefully pour the rendered fat and flavorful brown bits (drippings) from the roasting pan into the saucepan. You’ll need approximately 4 tablespoons of prime rib drippings. Add 4 tablespoons of red wine (or low-sodium beef broth) to deglaze the pan and scrape up any remaining flavorful bits. Finally, add 2 cups of low-sodium beef broth to the saucepan. Whisk all ingredients together until well incorporated and smooth.
• Bring the mixture to a rapid boil over high heat. Once boiling, immediately reduce the heat under the saucepan to medium-low. Allow the mixture to gently simmer for approximately 5 minutes, giving the flavors time to meld and deepen slightly.
• After 5 minutes of simmering, taste the jus and add salt and freshly ground black pepper as desired to achieve your preferred flavor balance. When you are satisfied with the rich, savory taste, carefully transfer the jus into a serving container, such as a gravy boat. Note: If the drippings contain any small pieces of meat or impurities, strain the jus through a fine mesh sieve before transferring it to the serving container for a smoother consistency.

To Serve Your Masterpiece

• With your prime rib perfectly cooked and crusted, it’s time for the grand finale: carving. Carefully slice the prime rib into individual portions of your desired thickness, always cutting against the grain to ensure maximum tenderness. Serve the warm prime rib immediately alongside the creamy, zesty prepared horseradish sauce and the rich, savory au jus. Enjoy your incredible holiday feast!
