Perfectly Roasted Prime Rib with Reverse Sear

1. Preheat the Oven

Start by preheating your oven to the lowest possible setting, ideally 150°F (66°C). If your oven doesn't go that low, use the lowest temperature available. This gentle heat will ensure the roast cooks slowly and evenly, retaining its juices and achieving a perfect, uniform doneness.

2. Season the Roast

While the oven preheats, season your standing rib roast generously with kosher salt and freshly ground black pepper. Don't be shy with the seasoning; it forms a delicious crust and enhances the meat's natural flavors.

3. Prepare the Roast for Cooking

Place the seasoned roast fat cap up on a V-rack set inside a large roasting pan or on a wire rack placed over a rimmed baking sheet. This positioning allows for even airflow and cooking around the meat.

4. Cook the Roast

Insert an instant-read thermometer into the thickest part of the roast, avoiding bone. Cook the roast in the preheated oven. If your oven is set to 150°F, it will take about 5.5 to 6.5 hours. If set to 250°F, it will take around 3.5 to 4 hours. The goal is to reach an internal temperature of 120-125°F (49-52°C) for rare, 130°F (54°C) for medium-rare, or 135°F (57°C) for medium to medium-well. The slow cooking process ensures the meat is evenly cooked and remains juicy.

5. Rest the Roast

Once the roast reaches your desired internal temperature, remove it from the oven and tent it loosely with aluminum foil. Let it rest for at least 30 minutes and up to 1.5 hours. Resting is crucial as it allows the juices to redistribute throughout the meat, resulting in a tender and flavorful roast.

6. Preheat for Searing

While the roast is resting, preheat your oven to the highest possible setting, between 500 to 550°F (260 to 288°C). This high heat is essential for the final sear, which will create a beautifully browned and crisp exterior.

7. Sear the Roast

After the resting period, remove the foil and place the roast back in the oven. Let it sear for 6 to 10 minutes until the exterior is well-browned and crisp. Keep an eye on it to prevent burning.

8. Carve and Serve

Finally, remove the roast from the oven, carve it into slices, and serve immediately. Enjoy the perfectly roasted prime rib, with its tender, juicy interior and deliciously crispy exterior.
