It is one of the most tender beef cuts and has generous marbling throughout, which results in a delicious, tender, and juicy piece of meat.Beef rib roast is easy to cook: Start it in the oven at a high temperature to get browning on the outside, then lower the heat to cook evenly throughout. There is a fat cap that you can trim, but it's best to leave it on to keep in the juiciness. Beef rib roast is best at temperatures no higher than medium on the inside, but the outsides are usually well-done.This cut of beef usually requires seasoning with only salt and pepper, but it is possible to do a dry rub or brine with herbs and spices to make a delicious crust. It also pairs well with many sides, such as vegetables. An au jus sauce made from the vegetable juices and the drippings of the meat makes a great complement to the beef's juicy flavor.
