Step‑by‑Step Instructions for Perfectly Tender Slow Roasted Prime Rib with Reverse Sear

Step 1: Preparation
Start by asking your butcher to cut your standing rib roast off the bones and tie it for easy carving later. Once home, place the roast in a large roasting pan, allowing it to rest while you prepare the seasoning. This prime rib will be the star of your holiday dinner, so make sure to handle it carefully.

Step 2: Seasoning
The day before cooking, generously season the roast with kosher salt and freshly-cracked black pepper, ensuring it’s coated evenly on all sides. Refrigerate uncovered overnight to allow the exterior to dry out, which aids in achieving a perfect crust during roasting. This simple step enhances the flavor and texture of your Slow Roasted Prime Rib.

Step 3: Room Temperature
On the day of cooking, remove the prime rib from the refrigerator and let it sit at room temperature for about 2 hours. This step ensures the roast cooks evenly throughout. While it rests, preheat your oven to 250°F, preparing for the slow roasting process that guarantees juicy, tender results.

Step 4: Initial Roasting
Once the oven is preheated, place the rib roast, fat side up, on a v-rack in your roasting pan for optimal air circulation. Roast for 3 to 4 hours, monitoring the internal temperature with an instant-read thermometer. You’re aiming for 120-125°F for a perfect rare finish that showcases the deliciousness of your prime rib.

Step 5: Resting Phase
After reaching the desired temperature, remove the prime rib from the oven and tent it loosely with aluminum foil. Allow it to rest for 30 minutes. This resting period is crucial; it lets the juices redistribute within the meat, resulting in an incredibly moist and flavorful prime rib that will impress your guests.

Step 6: Searing
Raise the oven temperature to 500°F. Uncover the prime rib and return it to the oven for a final sear, cooking for about 5-10 minutes until the exterior is beautifully browned and crispy. This reverse sear technique will enhance the flavor and texture, creating a stunning presentation for your Slow Roasted Prime Rib.

Step 7: Serving
Once seared, remove the roast from the oven and let it rest briefly. Then, carve the prime rib and plate it beautifully. For a delightful finishing touch, serve with the optional Roasted Garlic Horseradish Cream Sauce on the side. This addition perfectly complements the tender, juicy slices, making your holiday dinner unforgettable!

Make Ahead Options

These Slow Roasted Prime Rib options are perfect for busy home cooks looking to save time during the holiday rush! You can season the roast with kosher salt and freshly-cracked black pepper up to 24 hours in advance, allowing it to refrigerate uncovered overnight to dry out the exterior for a perfect crust. Additionally, if you prefer, you can prepare the Roasted Garlic Horseradish Cream Sauce ahead of time and store it in the refrigerator for up to 3 days. Just remember to let the roast sit at room temperature for 2 hours before cooking it to ensure even cooking. When you’re ready to serve, simply follow the cooking instructions, and you’ll impress your guests with minimal last-minute effort!

How should I store leftover Slow Roasted Prime Rib?
Very! To keep your leftovers fresh, place them in an airtight container and store them in the refrigerator for up to 3-4 days. Make sure to slice only the portions you plan to eat; leaving the roast whole will help maintain its moisture.

What’s the best way to reheat Slow Roasted Prime Rib?
For the best results, preheat your oven to 250°F. Place the prime rib, covered with foil, in a baking dish to retain moisture.
