Cooking Roasts – Cooking Time For Prime Rib Roast

A Prime Rib Roast which is often referred to as a Standing Roast is the cut between the area of the chunk and the loin. It is taken from the rib primal which is very rare, expensive, tender, succulent and flavorful. The belief that the word prime is already the highest grade quality of beef as per United States Department of Agriculture (USDA) standards doesn’t necessarily mean it, it is just a label because it is expensive as compared to other cuts. The cut comprises the ribs from 6 to 12. A full prime rib roast contains 7 ribs enough to feed more than 14 people, a generous serving of 2 persons per rib. Having the best prime rib roast won’t guarantee that you’ll end up serving the perfect dish that can satisfy your palate. One most important factor in cooking this, is the time element. A required cooking time is one assurance for the best end-product.

To begin with, a reliable and an accurate meat thermometer is needed. Whether it is rare, medium-rare, or well-done an instant- read cooking or meat thermometer should be used to cook it properly. Internal temperature for rare starts at 120°F and going to 125-130°F for medium-rare. Here’s a guide to follow when cooking prime rib roast but remember to always check oven temperature as this affects greatly the baking time of the rib roast. Oven temperatures are not always correct so be sure to check it by placing an oven thermometer at the center of the rack and heat for 15 minutes at 350° F. If the temperature of the oven reads lower or higher than the oven setting after 15 minutes,then have it adjusted.
