Instructions

Step 1: The Long Temper (Non-Negotiable)

• Remove the roast from all packaging and pat it completely dry with paper towels.

• Place it on a rack set over a baking sheet or tray, and leave it on the counter to temper. Minimum time: 4 hours for a 4–5 lb roast; add 1 hour for each additional pound. The roast should feel cool but not cold to the touch.

Step 2: Season & Pre-Heat

• About 30 minutes before cooking, preheat your oven to 550°F (288°C). Ensure it is fully preheated—most digital ovens will indicate when ready.

• Just before roasting, combine equal parts salt, pepper, and garlic powder. Massage the mixture aggressively over the entire surface of the roast, including the bones and sides.

• Place the roast fat-side up in a shallow roasting pan. Do not add water. Do not cover.

Step 3: The High-Heat Blast

• Immediately place the roast in the preheated oven. Close the door and do not open it again.

• Cook for the exact time based on your desired doneness and the roast’s weight:

  • Rare (a cool, bright red center): 5 minutes per pound

  • Medium-Rare (a warm, pink-red center): 6 minutes per pound

  • Medium (a warm, pink center): 7 minutes per pound

• Example: A 5 lb roast for medium-rare = 5 x 6 = 30 minutes at 550°F.

Step 4: The Crucial Oven Rest

• When the timer goes off, TURN THE OVEN OFF. DO NOT OPEN THE OVEN DOOR.

• Leave the roast completely undisturbed in the closed, turned-off oven for 2 full hours. This is not a suggestion—it is the step that finishes the cooking gently and evenly from the outside in.

Step 5: Carve & Serve

• After 2 hours, open the oven door. The internal temperature should be between 125–135°F (for medium-rare), perfect for slicing.

• Transfer the roast to a carving board. Slice against the grain for boneless, or slice along the bones to release them before slicing the eye of the roast.

• Serve immediately with pan juices, horseradish cream, and au jus.

The Science & Why It Works

This method utilizes the principle of carryover cooking. The initial high heat creates a flavorful crust (the Maillard reaction) while the oven’s residual heat continues to cook the interior gently and evenly during the two-hour rest. This eliminates the dreaded gray band of overdone meat, yielding a perfect gradient from edge to center.

Pro-Tips for Perfection

• Weigh Accurately: Use a kitchen scale for precise timing.

• Thermometer Check: If you’re anxious, verify the internal temperature after the 2-hour rest. It should read 125–135°F for medium-rare.

• For Older Ovens: If your oven is not well-insulated, add 1 minute per pound to the initial blast time.

• Make It Your Own: Add fresh rosemary or thyme to the rub. For a next-level crust, spread a thin layer of mayonnaise or Dijon mustard over the roast before applying the dry rub.

• Leftovers: Cold prime rib makes the world’s best sandwiches. Slice it thinly for a luxurious treat.
