How to Choose a Prime Rib Roast

Prime rib, in our opinion, is one of the most amazingly tender and flavorful cuts of beef. But (and there is always a but) not only does it need to be cooked properly, the beef cut needs to be chosen with care as well.

What Section of the Cow does the Prime Rib Roast Come From?

This cut of beef comes from back or upper middle section of the animal, which gets little to no exercise. The result is an extremely tender piece of meat as it is an excellent combination of muscle and fat.

Prime Rib Roast Facts

Markets or grocers will sell cuts of beef that are labeled with one of three grades:

  • Select
  • Choice
  • Prime

There are technically more than three grades of beef, but these are the three that are labeled safe for human consumption. Prime is the highest grade and most expensive. It is the most tender and has the most marbling (intramuscular fat) of the three grades. Only about 2.9% of all beef is graded Prime.

The “Prime” in Prime Rib does not indicate the grade of beef. It has become somewhat of a general term. Other terms are standing rib roast, or prime rib roast. The “Prime” refers to the Primal cut of beef.

Also, it is a little-known fact that Ribeye are steaks that were cut from a Prime Rib Roast while it was uncooked. What you see on restaurants menus as Prime Rib are steaks sliced off the roast AFTER it has been cooked.

When Choosing a Prime rib roast, one wants to look for when is called Marbling (inter -muscular fat). Marbling is the small flecks of fat that are interspersed within the meat. Don’t select a piece that has large, thick strands of fat running through the meat. These thick strands are difficult to render, and you can overcook the meat trying to do that.

Opt for a bone-in prime rib roast. Leaving the meat on the bone adds more flavor.
