Ingredients
- 5 lb Bone‑In Prime Rib Roast (Chuck End) (Trim excess fat to about 1/2 inch; keep bone for flavor and insulation)
- 2 tablespoons Kosher Salt (Coarse; used for dry‑brine)
- 2 teaspoons Freshly Ground Black Pepper (Season generously)
Instructions
Trim and Prepare the Roast
Using a sharp knife, trim excess fat from the prime rib to about a 1/2‑inch thickness, leaving the bone intact.
Time: PT5M
Dry‑Brine the Beef
Generously coat the roast on all sides with kosher salt and freshly ground black pepper. Place the roast on a rack set over a sheet pan and refrigerate uncovered for at least 24 hours, up to 4 days.
Time: PT15M
Low‑Temp Roast
Preheat the oven to 250°F. Insert a meat thermometer into the thickest part of the roast, avoiding the bone. Roast until the internal temperature reaches 130°F for medium‑rare, about 4 hours 30 minutes.
Time: PT4H30M
Temperature: 250°F
Rest After Low‑Temp Cook
Remove the roast from the oven, loosely tent with foil, and let it rest at room temperature for 1 hour.
Time: PT1H
High‑Heat Sear
Increase the oven temperature to its maximum (450‑500°F). Once preheated, return the roast to the oven for 10‑15 minutes, or until the exterior is deeply browned and crisp.
Time: PT15M
Temperature: 500°F
Final Rest Before Carving
Transfer the roast to a carving board, keep it loosely covered with foil, and let it rest for 10 minutes.
Time: PT10M
Carve the Prime Rib
Using a carving knife, cut along the bone to remove it, then slice the meat into ½‑inch thick slices against the grain.
Time: PT10M
