PRIME RIB ROAST TIMES RECIPES

Steps:

• Remove the roast from the refrigerator 2 or 3 hours before cooking.
• Preheat oven to 450.
• Rub butter on the cut ends of the roast.
• Combine flour, salt and pepper together in a small bowl, and then massage the mixture all over the meat.
• Set the roast, rib side down, in a shallow roasting pan (the ribs act as a natural rack), and place in the oven. Roast for approximately 20 to 30 minutes, or until the roast is nicely darkened. Reduce oven to 350 and continue to roast, basting every 15 or 20 minutes, until the roast reaches an internal temperature of 125 degrees (for medium-rare) on an instant-read thermometer. Remove the roast to a cutting board and let rest for 20 minutes before carving into either huge slabs or off the bone entirely and then thin slices.

Steps:

• Mix up 1 tablespoon + 1 teaspoon each of onion salt, seasoned salt, and garlic powder, for a total of 1/4 cup of seasoning mix.
• Pat the seasoning mix on both ends of the roast as well as the fat side. (The salt may not stick as well on the fat side, but don’t worry about it.)
• Set the seasoned roast on a roasting rack, bone-side down and fat-side up. Place the rack in a large roasting pan, and insert your meat thermometer into the middle of the roast.
• Place the roast into a 500° preheated oven, uncovered, and cook for 5-6 minutes per pound.
• Then shut the oven off completely, and DO NOT OPEN THE OVEN DOOR FOR TWO HOURS. 
• After two hours, check the temperature of the meat. If your thermometer reads 135-140°F, it’s done! (If it isn't quite to temp yet, just put it back in the oven at 375°F until it's done.)
