fatty flank

MeatYear-round; beef flank is available continuously from commercial suppliers, though grass-fed varieties may show seasonal variation in fat composition based on grazing periods.

Fatty flank is a rich source of complete protein and iron, with elevated fat content (particularly saturated fat) that contributes significantly to its caloric density and flavor profile.

About

Fatty flank is a cut of beef derived from the abdominal muscles of the bovine, located along the lower sides of the animal between the plate and the hindquarter. This cut is characterized by significant intramuscular fat marbling and connective tissue, making it notably more fatty than lean flank. The meat is deeply flavored with a beef-forward taste and moderately firm texture that becomes tender when properly prepared through slow cooking or braising methods.

Fatty flank is prized in cuisines that value fat content for flavor and mouthfeel. It is less tender than premium steaks but contains enough marbling to develop rich, savory characteristics during extended cooking. Different butchering traditions yield variations in thickness and fat distribution; some regions prefer thicker sections suitable for braising, while others emphasize thinner cuts for grilling.

Culinary Uses

Fatty flank is predominantly used in slow-cooking applications where the fat renders and tenderizes the meat through extended heat exposure. It is a staple in braised dishes across European, Asian, and Latin American cuisines—including French pot-au-feu, Italian stracotto, Chinese braised beef (牛腩, niu nan), and Korean jjim preparations. The high fat content makes it suitable for stocks and broths, contributing depth and body. Leaner specimens may be briefly marinated and grilled or pan-seared over high heat, though it benefits from proper slicing against the grain to ensure tenderness.

Forms & Preparations

Whole cut — Intact flank muscle with fat cap and intramuscular marbling; typically 4-8 lbs, used whole for pot roasts or large braises.
Thick steaks (2-3 inches) — Cut perpendicular to the muscle fibers; retains fat marbling and can be braised or slowly grilled.
Thin sliced — Sliced thin against the grain; used in Asian stir-fries, hot pots, or raw preparations (e.g., carpaccio) when high quality.
Stew meat (1-2 inch cubes) — Cut into uniform pieces for even braising in stews, curries, and braises.
Ground/minced — Processed into ground beef for burgers, meatballs, and forcemeats; higher fat content than lean ground beef.
Rendered fat/tallow — Fat trimmed and slowly melted to produce rendered beef fat for cooking, stocks, and traditional preparations.
