Chuck Tenderloin

Chuck Tenderloin has a rich, beefy flavor that is best used for slow-cooking. When tenderized with a marinade, chuck tenderloin can also be used for grilling.  The chuck tenderloin is also a lean protein option that still packs a mouthful of flavor.

The chuck tenderloin, also referred to as the “Mock Tender” for its similar appearance to a tenderloin, can be found in the shoulder region known as the Chuck region. The chuck tenderloin consists of the supraspinatus muscle, which is found forward of the large chuck subprimal in the shoulder clod.
