Chuck steak is
a cut of beef and is part of the primal cut
known as the chuck. The typical chuck steak
is a rectangular cut, cut about 1" thick,
with parts of the shoulder bones, and is
known as a "7-bone steak".
This is a
reference to the shape of the bone
resembling the numeral '7', not the number
of bones. This cut is usually grilled or
broiled; a thicker version is sold as a
"7-bone roast" or "chuck roast" and is
usually cooked with liquid as a pot roast.
The bone-in chuck steak or roast is one of
the more economical cuts of beef.
Boneless steak cuts from the chuck also
include the chuck tender, chuck filet, and
boneless cross-rib steak.
