Beef Glossary & Beef Cut Diagram

When looking up cuts of beef, it’s helpful to refer to the beef cut diagram, courtesy of the National Cattleman’s Beef Association. If you enjoy this Beef Glossary, we have a food glossary for almost every category of food.

See hanger steak.
Organic beef is very similar to natural beef, except that everything labeled “organic” adheres to strict USDA Organic program criteria and the ranch has been inspected and certified by an official organic certifier. There are numerous criteria, including no use of antibiotics (an ill animal that needs medicine is removed from an organic herd and generally moved to a natural herd) and there is no use of pesticides on any food eaten by the animals or on any hay it may sleep on. Many natural ranchers adhere to organic practices but elect not to undertake the time and expense of organic certification.
Oxtail was once really from an ox, but today it is usually beef or veal tail. While quite bony and gelatinous meat, is very flavorful, and is popular in British and Caribbean cooking, in stews or soups. Oxtail requires long, slow braising.
The overall taste appeal (tenderness, juiciness and flavor) of cooked, lean beef.
A term that is incorrectly used as synonymous with grass-fed beef. As defined by the American Grassfed Association (AGA), grassfed means “those food products from animals that have eaten nothing but their mother’s milk and fresh grass or grass-type hay from birth to harvest—all their lives.” If an animal is “pasture raised,” its food can be supplemented with grain (corn feed or a mix of cheaper grains)—i.e., not purely grass fed.
See New York cut.
A pot roast is a less-expensive cut of meat, cooked slowly in a covered pot with water, and often root vegetables and potatoes, until it is moist and tender. While any type of meat can be cooked in this way (pork or veal, for example), it is most closely associated with beef. A beef brisket is often cooked as a “pot roast.”
PORTERHOUSE or T-BONE STEAK
The porterhouse is sometimes called the “king of all steaks” because it combines two top cuts of meat in one steak. On one side is a bone-in strip steak; the other side is a portion of tenderloin (filet mignon). The porterhouse is a larger T-bone steak, with more of the tenderloin and the strip steak.
The price of beef is largely based on corn prices, the grain on which cattle feed in the latter days of their growth to develop the marbling. The degree of marbling is a major indicator of whether a piece of beef will be graded Prime or Choice. Ethanol uses up to 26% of the U.S. corn crop. As ethanol demand increases, the price of corn rises. As the price of corn rises, ranchers cut the number of days in which they feed cattle grain. There is less marbled meat, and thus a smaller supply of Prime and Choice meat.

PRIMAL or WHOLESALE CUTS
Basic major cuts that result from cutting carcasses and sides into smaller portions. The wholesale or primal cuts are the brisket/foreshank, chuck, flank, loin, round, short plate, short loin and sirloin. The primal cuts are further broken down into subprimal cuts. Examples of subprimal cuts of beef are the top round, whole tenderloin and rib eye.

- The brisket primal (the breast) is typically cut into smaller portions are pickled to produce corned beef brisket or cured to make pastrami.
- The chuck primal (the shoulder) is cut into subprimal roasts and steaks: blade steak, chuck short ribs, cross rib pot roast, flat-iron steak, ground chuck for hamburgers and stew meat.
- The flank primal (located directly beneath the loin) is cut into subprimals flank steak and London broil.
- The foreshank primal (the shank is the arm of the animal), very flavorful and high in collagen, is ground into lowfat ground beef. In the foodservice industry, it is used to make soups and stocks.
- The loin primal (located behind the primal rib) is cut into subprimals filet mignon, porterhouse, T-bone, sirloin butt roast, sirloin steak and strip steak.
- The rib primal (the ribs and portion of the backbone) is cut into subprimals beef short ribs, boneless rib eye roast, rib eye steaks and roast prime rib of beef.
- The round primal (the hind leg of) is cut into subprimal round roasts and round steaks.
- The short plate primal (rib bones below the primal ribs) is cut into subprimal short ribs and skirt steaks.
See USDA Prime.
Prime rib refers to the finest beef, with even marbling and a creamy layer of fat. It must be USDA Prime, not USDA Choice. Only about 3% of the beef in America is graded USDA prime. Because of the scarcity, it is generally carried only by the finest butchers and restaurants. Often, rib roasts masquerade as prime rib in supermarkets, which typically carry USDA Choice (and lower grades—see all the grades of beef), not USDA Prime, meats. See rib roast.
