The rib eye or ribeye (known as Scotch fillet in Australia and New Zealand) is a boneless rib steak from the rib section of cattle, though occasionally other animals will have cuts described as ribeye, such as deer. The cut is popular for cuisines around the world, with French language butchering describing a similar entrecôte steak, and Latin American cusines having similar concepts, like ojo de bife in Argentina and lomo vetado in Chile.
The cut is the same as a prime rib but without the bone.
The Ribeye is typically described as tender, and can be treated like a premium steak.
Ribeye steaks are mostly composed of the longissimus dorsi muscle but also contain the complexus and spinalis muscles. The longissimus dorsi is also referred to as the "eye of the ribeye". The spinalis is also referred to as the "ribeye cap" and the complexus is a small muscle at the front of the ribeye which may be trimmed off by the butcher.
A "tomahawk chop" steak is a ribeye beef steak, trimmed leaving at least five inches of rib bone intact, French trimmed taking the meat and fat from the bared bone to create a distinctive ‘handle’ to the steak.
Rib cap is "taken from the top part of a rib-eye. The muscles there are not used as often as other parts of the cow, giving it a tender texture—though unlike a tenderloin, it also boasts flavor-boosting marbling."
