Prime Rib Roast Recipe Turn Off Oven: Reverse Sear Method for Perfect Medium Rare

Achieving perfect medium rare prime rib every time is simpler than you think with the reverse sear method. This professional technique starts low and slow, then finishes with a high-heat sear for ideal results.

The secret lies in the oven management: cook at 200°F until the internal temperature reaches 110°F, then turn off the oven and let it rest. This ensures even cooking without overcooking the edges.

What emerges is a roast with a perfectly pink center from edge to edge, juicy and tender throughout. The reverse sear method eliminates the guesswork of traditional high-heat roasting.

This approach delivers consistent, restaurant-quality results with minimal effort. The turn-off-the-oven step is the game-changer for evenly cooked prime rib.

Quality cut plus a handful of aromatics. Restaurant-grade results start here.

The prime rib is non-negotiable here. Bone-in roasts from a reputable butcher yield the most consistent results, with the bone acting as a natural rack for even heat distribution. Look for heavy marbling—those white fat streaks ensure juiciness. Costco and Whole Foods carry excellent pre-trimmed options if you’re short on time. Avoid pre-seasoned roasts; you want full control over the salt and pepper crust.

No fresh herbs? Dried rosemary and thyme at one-third the amount work, but fresh delivers superior aroma. For the wine, any dry red like Cabernet Sauvignon or Merlot is ideal—avoid sweet varieties. The butter can be swapped for ghee if you prefer a higher smoke point. Skip the horseradish cream if you dislike the bite, but it’s a classic pairing worth trying.

Store the uncooked roast in the coldest part of your fridge for up to 3 days. Once cooked, it keeps for 4-5 days wrapped tightly. The au jus can be made ahead and reheated—flavor actually deepens overnight. Always bring the roast to room temperature before starting the reverse sear process.

Step-by-Step Instructions for Prime Rib Roast Turn Off Oven

This reverse sear method guarantees even cooking and a perfect medium-rare finish every time.

Step 1: Season and Slow-Roast the Prime Rib Roast

Pat the 5 lb Prime Rib Roast completely dry with paper towels. This ensures the 2 tbsp Kosher Salt and 1 tbsp Freshly Ground Black Pepper adhere properly to form a flavorful crust. Rub the seasoning aggressively over the entire surface, including the fat cap and ends.

Place the roast fat-side up on a wire rack set in a roasting pan. Surround it with the 6 cloves Garlic Cloves, 4 whole Fresh Rosemary Sprigs, and 4 whole Fresh Thyme Sprigs for aromatic infusion. Insert a meat thermometer into the thickest part of the roast, avoiding bone and fat.

Preheat your oven to 250°F. Roast the prime rib until the internal temperature reaches 115-120°F for medium-rare, which typically takes 2 to 2.5 hours for this size. The slow rise in temperature ensures even cooking from edge to center.

Step 2: Rest and Preheat for the Sear

Once the prime rib reaches 115-120°F, remove it from the oven and tent loosely with foil. Turn off the oven completely—this is the critical “turn off oven” moment that defines this method. Let the roast rest while the internal temperature continues to rise toward 125°F.

Place your roasting pan with the rack and aromatics on the stovetop. Add the 2 tbsp Olive Oil and 4 tbsp Unsalted Butter to the pan. Turn the burner to medium-high heat to preheat the pan for searing. The residual heat from the oven and the direct flame will create a perfect crust.

The roast can rest for up to 30 minutes during this phase. This extended rest allows the juices to redistribute, and the internal temperature will stabilize at the ideal medium-rare range.

Step 3: Sear for a Crust and Build the Au Jus

Return the prime rib to the hot pan, fat-side down. Sear for 2-3 minutes until deeply browned and a crust forms. Flip and sear the other side and ends for 1-2 minutes each until uniformly deep brown.

Transfer the roast to a cutting board and tent with foil. Pour off excess fat from the pan, leaving the browned bits. Place the pan over medium heat, add the 1 cup Red Wine, and deglaze, scraping up all the fond. Reduce by half, then add the 2 cups Beef Broth and simmer for 5 minutes to create a rich au jus.

Step 4: Carve and Serve

Let the prime rib rest for an additional 10-15 minutes before carving. This final rest ensures the juices settle completely. Slice between the bones for even portions, or remove the bones and carve the meat into 1-inch thick slices.

Strain the au jus and serve it alongside the prime rib. For a creamy accompaniment, mix the 2 tbsp Dijon Mustard with the 2 tbsp Prepared Horseradish and offer it on the side. The roast should be uniformly pink from edge to edge, with a crisp, flavorful crust.
