Ingredients

  • 1 boneless prime rib roast Prime grade and first cut recommended (see note)
  • 1 tablespoons canola oil see note
  • 1 tablespoon coarse salt kosher salt or sea salt
  • 1 tablepsoon black pepper freshly ground
  • fresh sprigs rosemary or thyme for garnish

Instructions

  • Remove the roast from the refrigerator 1-2 hours ahead of time.
  • Preheat the oven to 450°F, placing the oven rack in the middle position and turning on the convection/forced air (if available).
  • While you’re waiting, prepare the meat. Pat it dry with paper towels to remove excess moisture. Then score the fat on the outside about 1/8-inch deep using a sharp knife in a diamond pattern with the cuts spaced an inch or so apart.
  • Rub the meat on all sides with the oil, followed by the salt and pepper. Place it fat-side up in a roasting pan fitted with a wire rack. Scatter the optional fresh herbs around the roast, reserving some for serving. If you’re using a thermometer, insert the probe into the middle of the meat.
  • Place the meat in the oven and roast for 10 minutes. Then reduce the heat to 325°F. Every 30-60 minutes, baste the meat by spooning of bulb-basting the pan juices onto the meat. If the meat gets dark brown before the final 30 minutes, cover loosely with aluminum foil.
  • After 60-90 minutes (or longer for large roasts), start checking the internal temperature of the meat. Insert the probe of an instant-read thermometer into the center of the roast: 115°F is rare, 125°F is medium-rare, 135°F is medium, 140°F is medium-well and 145°F is well-done. Note that temperatures will typically rise another 10°F from these levels out of the oven.
  • When your desired doneness is reached, remove the roast to a carving board and tent with foil. Let it rest undisturbed for 15-20 minutes to allow the juices to redistribute throughout the meat.
  • Slice against the grain to serve. Note that the outside edges will be more cooked and the center sections more red, so you can distribute servings to guests accordingly.

Notes

  • Beef: When shopping, look for well-marbled beef that is prime or select grade, and ideally the smaller first cut from the loin end. Buy ½ - ¾ pound per person depending on appetites.
  • Oil: Use a high-temperature oil that will not smoke in the oven. Options include canola, sunflower, safflower and refined olive oil. Avoid extra virgin olive oil.
  • Gravy: To make gravy, pour the pan drippings into a medium saucepan over medium-high heat. Remove excess fat so there's only 1/4 cup fat plus brown bits and juices (a fat separator is helpful for this). Once the fat bubbles, whisk in 1/4 cup flour and let it bubble for 30 second. Then dribble in 3 or 4 cups of milk, broth or water, whisking continuously until thick enough to coat the back of a spoon. Taste and season with salt and pepper.
