Prime Rib Roast

Begin by taking the rib roast out of the refrigerator and letting it sit at room temperature for approximately 3 hours, depending on its size. This step allows the roast to reach a more even temperature, which is essential for cooking.

Next, preheat your oven to 425 degrees Fahrenheit (220 degrees Celsius). To make cleanup easier, line a roasting pan with aluminum foil before proceeding.

Carefully place the rib roast onto the prepared roasting pan. Remove excess moisture from the surface of the roast by gently blotting it with paper towels.

In a separate bowl, combine flour, pepper, salt, paprika, onion powder, garlic powder, and celery seed. Sift the dry ingredients together until they are well-blended.

Dust the rib roast evenly with the flour mixture, making sure to coat it all over.

Place the coated rib roast in the preheated oven and continue cooking until it reaches your desired level of doneness. The recommended cooking time is approximately 4 1/2 hours (20 minutes per pound) for medium-rare. To ensure the roast is cooked to your liking, use an instant-read thermometer inserted into the center of the meat. The internal temperature should be at least 120 degrees Fahrenheit (49 degrees Celsius) for medium-rare, 130 degrees Fahrenheit (54 degrees Celsius) for medium, or 140 degrees Fahrenheit (60 degrees Celsius) for well-done.

Cover the roasted rib roast with aluminum foil and let it rest on a warm surface, such as a countertop, for 30 minutes to 1 hour before slicing.
