What is prime rib roast?
Prime rib roast is a cut of beef from the primal rib. Therefore, it is known as prime rib, beef rib roast or standing rib roast.

A standing rib roast usually contains anywhere from two to seven ribs. Besides, the New York rib roast and rib-eye rib roast are often sold at the stores when the holiday season approaches.

Then, turn off the oven. Leave the rib roast in the oven for 55 minutes to 70 minutes. And, please don’t open the oven door! This is very important.
