Oven-Roasted Prime Rib with Dry Rib Rub
In a small bowl, combine salt, mustard, black pepper, garlic, onion powder, thyme, oregano, coriander and celery seeds. Set aside 1/4 cup. (Transfer the remaining mixture to a small jar. Store in a cool, dry place for up to 3 months. Stir or shake before using.)Advertisement
Rub oil over meat. Sprinkle the 1/4 cup spice mixture evenly over meat; rub in with your fingers. Make six 1x1/2-inch knife slits into the fat side (the slits allow the seasoning to penetrate into the meat).* Place meat, fat side up, in a large roasting pan. Insert an oven-going meat thermometer into center, being careful that it doesn't touch the bones.
Roast beef in a 350° oven for 1-3/4 to 2-1/4 hours for medium-rare (135°) or 2-1/4 to 2-3/4 hours for medium (150°).
Transfer meat to a cutting board. Cover with foil and let stand for 15 minutes before carving. (The temperature of the meat will rise 5 to 10 degrees during standing.)
At this point, you can cover the meat loosely with plastic wrap and chill up to 24 hours before roasting.
