According to FoodReference.com, rib eye is one of the top five favorite beef entrées. It's an expensive cut of meat but also one that's tender, juicy and filled with flavor. This favorite steak is an excellent source of complete protein, zinc, selenium, phosphorus, niacin, and vitamins B6 and B12.
A rib eye steak comes from the large end of the beef rib (near the shoulder). Rib eyes are usually boneless but may be bone-in. It is well-marbled, with bits of fat interspersed in the muscle that give the steak it's flavor and tenderness. The quality of beef is graded according to the amount of marbling. A rib eye that has abundant marbling is "prime" and "choice" rib eyes contain a moderate amount of marbling.
